The closest relatives
People, 22 pairs of chromosomes otozom, and X and Y sex chromosomes are a total of 23 pairs of chromosomes. Is the closest animal relatives until 1955, and other human primates such as chimpanzees are thought to have 24 double chromosomes.
In this thesis, Albert Levan and Joe-Hin Tijo'nun new microscopic techniques using expired.
A closer inspection of the human chromosome number 2, which still exists in chimpanzees showed that the merger of two smaller chromosomes. This merger makes us human is one of evolutionary events. At the same time, the human and chimpanzee genome shows 96% similarity türediklerinin separated from a common ancestor 6 million years ago and is an indication that they are closely related.

A core of each of our cells and 22 otozom (autosome) chromosomes are a pair. The roles of sexual selection is Otozom chromosomes. Most readers who read this article you have two sex chromosomes. Females have two X chromosomes. The X chromosomes of the DNA molecule consists of two large approximately 155 million nucleotides in length. Men are different, one of the X chromosomes and one Y chromosomes are smaller. The length of the Y chromosome is only 50 million nucleotides. X chromosome has more than a thousand genes, whereas the poor in terms of the Y chromosome gene (27). Y, X is very small according to (a fifth of the size), although the detection of male eşeyinin and has an important role in the development. However, most men do not know the Y chromosome gradually deteriorates.
Mammalian Y chromosome, the origin of chromosomes in terms of lifestyle is extremely normal. In fact, the Y chromosome common ancestor of mammals 100 million years ago, today is probably very similar to the X chromosome. But suddenly something has happened to reverse. This is perhaps a change in the regulation of a gene in the Y chromosome or mutation. This mutation has the effect of changing control of mammalian sexual selection. Whatever happened to the male and female role in determining the difference between the fetal development was the switch or changes. Therefore, the Y chromosome began to lose the ability to communicate with other chromosomes. In other words, the Y-chromosome genome has lost the ability to interfere with other chromosomes or double creation. "Re-mix" loss of ability of these chromosomes, genes eliminated the ability of balancing the harmful mutations. Because the "re-mix", the value of an organism's selection of the harmful effects of mutations, chromosome is an effective method of mutual corrections.
Interference decreases, the Y chromosome genes in the genome lost or slipped, or other chromosomes. Thus, the Y chromosome genes in a number of times of thousands of genes in humans, yet only 27 fell. Other mammals, by looking at the number of H kromozomlarındaki gene, we can easily see that the decline in kromozomumuzdaki.
Over time all this is bad news for the Y chromosome, because if the losses continue in this manner, if at the end of the human genome, the Y chromosome will disappear. Gurularından human genetics at Oxford University, Brian Skyes, looking at the current birth rates, this decline in relation to the Y chromosome, 5,000 generations, or about 125,000 per year 99% predict a decrease. Skyes the human genome, masculinity or femininity predicts change detection equipment. Thus, detection of another chromosome, or male eşeyinin will, or the worst possibility for men, masculinity saptanışının the disappearance of the human genome completely exhausted male sex in humans. This bizarre scenario in sexual üreyemeyecekler people, because there will be only the female sex.
We, however, currently have a Y chromosome, and the distribution of populations in the world for our understanding of this chromosome is a powerful instrument.

Observations on the terminology of Evolution
Evolution terminology key phrases
According to Turkish to English vocabulary and the power of expression, especially scientific and technical issues that we all have a weaker malumu. One of the main problems related to the positioning of 'change' about the concept. Evolutionary terminology often take a look at last the following phrases:
Change: The most general definition of change or no change. According to the meaning of content is changing, but mostly instant, spontaneous and / or being used for the quantitative deşiğiklikleri vugulamak. Change in eye color, changes in the genetic sequence, genetic change, the change in allele Frequencies etc.
Variation: Diversity, variation. Properties of the population, mostly among members of the species being used to refer to the observed changes. Is also used to highlight the diversity between species. One of the common mistakes 'diversity,' 'change' or 'changes' translation of that.
Mutation: Mutation. Gene sequences of random and spontaneously encountered genetic changes in basal replace hardware. One of the common mistakes' mutasyon'un 'change' translation of that.
Evolve: evolve. The process of evolution under the cumulative (cumulative) and uyarlanımlı (adaptive) undergo evolutionary changes. Uyarlanımlı of change is very important, because the adaptation (adaptation) without the evolution does not happen.
Adaptation (Wikipedia): adaptation. In a process of natural selection provided a better fit around the creature.
Natural Selection (Understanding Evolution site): Değal selection. Different genotypes in a population, showing that the population differences in gene frequencies will lead to changes in survival or reproduction. One of the common mistakes' natural seçilim'in 'natural selection' translation of that.
As for the definition of Evolution, evolution can be considered as a phenomenon, can be taken as a theory, or as a process that can be handled. Does the philosophy of science or a theory of evolution is a phenomenon that is often the discussions. But I changed the scientific content derived from living organisms evolution simply 'process' meaning to. Because the evolution of the scientific content of a 'process' (process) being the most obvious and important feature of his property.
Come take a look at Understanding Evolution site you'd like to know:
Evolution (Understanding Evolution site): Evolution. The simplest definition of biological evolution, varied derived. The definition and evolution of small-scale (ie, gene frequencies within a population (*) to change from generation to generation) and the evolution of large-scale (ie the generation interval of the passing of a very different species from a common ancestor türemesini) covers.
(*) Please note: In fact, 'gene frequency' rather than the 'allele frequency' to use the more accurate description, but there are some problems with this semantics, I will again in the future to this issue.
Allele (Understanding Evolution site): Allele. One of the different versions of a gene locus. The same locus in different individuals may have different alleles in a population. For example, the locus that determines the color of the yellow color of pea green color of the allele or alleles that can be found. At the same locus different alleles are often separated by large and small letters (for example, such as Y and y alleles).
Frequency of gene expression related to the semantic problems
First, if you take a look at the definition of modern Sentez'in evolution:
This last is a common definition of scientific literature and dictionaries. Of course 100% correct, but a little more technical and difficult to understand for an ordinary reader seems to me a definition.
An interesting point is that the University of California, prepared by the Understanding Evolution site is actually a translation of the main text, that is, for access to a wide audience. Caught my attention, perhaps too technical for kaçmamak 'allele frequency' rather than 'gene sıklıklarındaki' talk about the changes. Allele frequency of 'modern synthesis' strongly emphasizes and technically more accurate statement, but the upper stage of the modern synthesis of a issue, so perhaps the concept of allele-forward (advanced) can be activated at some stage he may have thought.

Dear readers,
So far, thank you very much indeed for your interest in my blog.
During the month of March , "Understanding Evolution" site, I'll be trying to help friends who may be a reduction in the frequency of Evolution Olgusu'ndaki my messages, I hope you for your understanding.
"Understanding Evolution" is really a very important study. To answer the question marks in the minds of human evolution that may occur on the street, factual, objective and scientific transfer.
Please follow the painstaking work of this, please notify your spouse dostunuzu. Theory of evolution, science, light yaymamıza please help ..
Sağlıcakla thick and not go somewhere, do not, evolution will continue on the current developments in the messages are not interesting.

Natural selection is common to what extent?
One of the simplest questions biologists ask about natural selection, would be interesting, the answer given is one of the most difficult ones. Natural selection, the formation of a genetic change in the general population to what extent is responsible? Most of the physical properties of natural selection of living things is a serious suspicion that there's nobody there - beak, biceps, large-scale features, such as the formation of the brain there is another reasonable explanation.However, natural selection, the changes at the molecular level on the role of directing serious doubts on the degree of activity was heard. I wonder that occur in DNA over millions of years of evolutionary change-other than a process-how much is directed by natural selection?
Arrive until the 1960s, biologists from the response to this question, "almost all" has been, but Japanese researchers Motoo Kimura, a group led by population geneticist, sharply challenged this view. Kimura-environmental conditions to increase the frequency of a feature initially rare "positive" does not affect natural selection-often argued that molecular evolution. However, Kimura, populations or high frequencies of permanent genetic mutations, almost all of the selection in terms of reaching the "neutral" is, that this or that said there was a significant influence on the selection value (Naturally, they continue to occur at a higher rate of harmful mutations, but for not achieving at high frequencies in the population, in evolutionary terms sondurlar predicament.) Current environmental conditions, neutral mutations are essentially invisible, such changes, compile time, greatly changing the genetic, population evolve unnoticed in a quiet manner.
By the 1980s a lot of evolutionary geneticist "neutral mutation" theory had been accepted. However, the data on this theory often dolaylıydı; more directly lacked the critical tests. Two separate development that helped to solve the problem. First, population geneticists, genome neutral changes, a simple statistical tests for the purpose of distinguishing those who have developed compatible. Second, new technology has made it possible to sort the entire genome of many species, so that large amounts of data acquired in this statistical test was applied. New Data "neutral mutations" theory, dropped it into the wild showed the importance of natural selection.
University of California, Davis, David J. Begun and Charles H. One made by a team led by Langley's research , according to two fruit fly species belonging to the class of Drosophila DNA sequences were compared. Scientists have studied both species approximately 6,000 genes, and since the two species from a common ancestor ıraksadığından, which found that the genes was leaving. By applying a statistical test, at least 19% of 6,000 genes that revealed the neutral evolution, in other words, natural selection, evolutionary ıraksamasını yönlendirmişti one fifth of the genes examined (the statistical test applied by "moderate" (conservative), so the actual rate may be higher .) This is a trivial result of evolution does not offer unbiased-ie, the remaining 81% of genes may be genetic sürüklenmeyle ıraksamış. But natural selection, most "neutral mutations" theorist sanısının In contrast, species ıraksamasında prove that a greater role.

Western Australian Institute for Medical Research is a new trial (WAIMR), a young researcher, the complex structure of the human genome has brought clarity.
12 February 2009, "Molecular Cell", this new research published in the online site, covering the human genome sequence opened the curtain of a mystery - 98% of our DNA is the purpose?
The two research teams in the United States under a co-operation, WAIMR'dan Dr Archa Fox - an unknown reason, and in most gemomun - do not make the RNA encoding a unique set of functionality.
Fox, "a non-coding RNA, the 'Neat1'in, and important in every cell that acts as a repository çokbeneklerin ( paraspeckles ) discovered that the structural foundation. " he said.
"The human genome map is removed, only 2%, 25,000 units had been a big surprise to understand protein-coding genes is occurring. However, this alone we are cutting 2% of people açıklayamıyordu complex structure, the remaining 98% cut, if the protein yapmıyorsa What served to? study, an RNA encoding does not make the 'Neat1'in focused on the purpose, and have found that creating the structure of this RNA çokbeneklerin role. "
In 2002, Dr. Fox is a function of the cell in the nucleus and a tank-like "çokbenekleri" finds the first science-lion, çokbenekler proteins are important for the building materials store, so that when a command cells, secreted materials more efficiently, and faster production of proteins provided.
Çokbenekler, cells which proteins to be made for more rigorous supervision, and a protein in cells that need them, the realization of the process provided a method of saving the cells for 25 minutes. If you need to make an analogy çokbenekler, the cache memory of the computer's central processing unit (CPU cache) is like. So, like a cache of creative coding RNA, such as trying to unused.
Unlike coding genes do not make the RNA and protein molecules that do not help the production. Thanks to this new research, coding, do not make the RNA, just like proteins, that help to build important parts of the cell as part of a constructive davranabildiğini have learned.

Steven Scherer and 223 genes
Google "Steven Scherer," + 223 I do a research, dozens of creationist page appears. The source of the journal Nature, published in February 2001, "Initial sequencing and analysis of the human genome" (starting dizgilenmesi and analysis of the human genome), an article by. In this article, "The International Human Genome Sequencing Consortium," (International Human Genome Sequencing Consortium) has been prepared by. Steven Scherer, this consortium is just one of dozens of scientists.
Subsequently put forward controversial subject of the article "probable horizontal transfer" (Possible horizontal transfer) are covered under the title (see page 42/62.) Under this heading, the human genome, very similar to proteins found in bacteria but not seen in invertebrates that 223 pieces of the protein is detected being. A more detailed analysis, this protein synthesis 113'ünün genes in bacteria is a common, multi-celled, but had discovered the only vertebrates suggests.In this paper, these findings as a possible cause of horizontal gene transfer from bacteria to people, a transition in the opposite direction is more likely to be stressed.
Okay so far in such a scientific study of how the Creationists material is the subject of this section is really interesting.
At this stage a person is eccentric to the stage by Zacharia Sitchin. Zecharia Sitchin (d.1922), a writer of books describing the people astronotlarla alien origin.Sitchin, "Annunaki" (or "Nephilim") called for the creation of an ancient Sumerian culture, Solar System, the unseen aliens from the planet Nibiru long and is based on an elliptical orbit circulating suggests. Sitchin'in these opinions as natural scientists, archaeologists and historians yalanlanıyor.
Sitchin "The Case of Adam's alien genes" (the subject of Adam alien genes) in an article by the International Human Genome Sequencing Consortium, 223 found by the original gene, genomic evolutionary tree does not belong to any type of horse says, and as a result of these genes Adam argues that the human species began passing by aliens. Sitchin'in creationists and intelligent designers find this message, blogs, and sites in the issue immediately by moving the event that the bankruptcy of evolutionary theory and human evolution dayandırıyorlar is designed independently.
Easily escape from the eyes detail in this case is an interesting contrast to the claim that the Sitchin'in the original article, a consortium of people that is almost impossible to emphasize that bacterial gene transfer. The article in question from bacteria to human genes is more likely to be emphasized in the past. Thus, even this "alien" to human gene directly contradicts his saçmalığıyla a proposition directly.
After publication in the journal Nature, some researchers will compare a comprehensive data base for the International Human Genome Sequencing Consortium is not controversial, he cited the results. International Human Genome Sequencing Consortium nearly three months after publication, in May 2001, Rockville, Maryland, "The Institute for genomic Research (TIGR)" (Institute for Genomic Research), says a new study. Researchers during the evolution of bacteria by human beings as a relative (if the elapsed) showed very few genes may be in the past. Human, according to analysis of the genomes of bacteria and invertebrates, vertebrates gene in less than 50 people, in a certain period during the evolution of bacteria in the past may be, towards the end of an article published in Science Express, the magazine reported in May 2001.
Researchers have none of these genes directly from bacteria to human being is not possible in the past, whereas some proteins in bacteria are found only in humans and no pretense to be the cause of these genes in invertebrates and invertebrates due to mutations in the human and bacterial genes with saptanamaması announced.
Steven L. TIGR'de head of bioinformatics Salzberg "My friends and I have therefore called for transfer in humans of a bacterial gene could not find any. International Human Genome Sequencing Consortium, using the data described by 41, according to the Celera data, we found the 46 genes shared by humans and bacteria but did not find these genes in invertebrates crawl," he says, and adds, "But we can not claim that this passage of horizontal gene sharing."
In nature, horizontal transfer of genes between species is a phenomenon well-documented. Other bacteria, the bacteria can pass the gene, and also of human cells and organelles mitochondria were once free-living bacteria and in this way people spent their genes.
However, many evolutionary biologists, the way bacteria could pass genes in vertebrates say there is a strong evidence. Therefore, the Human Genome Sequencing Consortium, more than a hundred human proteins "pre-vertebrates or vertebrate species, from bacteria are passed horizontally" in the journal Nature was the big news proposition.
TIGR broadcast, horizontal transition is at least a huge exaggeration, and this thesis showed that it is possible to being completely wrong. On the other hand, no bacteria in vertebrates is currently impossible to prove whether the genes in the past. Instead, TIGR researchers, the available genomic data of the Nature article, tried to support the original description.
As authors of the Nature article, TIGR researchers also unusual species 'distribution traces' bioinformatics tools used to search for. This strategy involved the detection of sequences similar to different types. Salzberg "Array gereçtir strong resemblance, but must be very careful when using," he continues, "Similarity of two proteins is possible that a common ancestor and shows that the functioning of proteins similar to, but does not say when they left."
TIGR'den Jonathan Eisen, says this approach is effective but is often misleading. Unusual distribution traces, or the fact that the loss of existing genes, but as recognition kayıpmış seem to be mutated may be due. Eisen, "the greatest evolutionary problem of the original study, the loss of genes that invertebrate varsaymasıdır" he said, and "the loss is very common, especially in small genomes gene studies have hundreds if not thousands of envisioning" he added.
Accuracies misleading way to a World Cup qualifier, more data bulundurmaktır example. According to the publication Nature, the human genome predicted protein sequences of four invertebrate sequence and the arrays were compared with other invertebrate eukaryotes. These four invertebrate species, yeast, worms, flies and Arabidopsis plants, respectively.
The other hand, TIGR data set, open to the public genomic data, including hundreds of invertebrate species found partial genes, almost all involved. Researchers "Nature reported the team is not the original set of genes, 21 tenesinin sponge invertebrates, soybeans, and marine invertebrate organisms were detected as the parent," announced. Salzberg, "where you can only omitted the result is that the initial study of these genes," he said. Therefore, the re-analysis, the number of genes in the human gene was detected bacteria is said, to compare the human genome is dependent on how many invertebrates have shown that the genome scanned.
Researcher says Eisen, "The origin of the human genome of bacteria had been having a few hundred genes, even if the human genome has 25,000 genes, ie, Nature of a billion years to 600 million during the race the team entered the vertebrate can be found which would have been a part of one per cent of the genome", and adds, "To tell you the truth, this number is a number that is not so interesting."
So what happened to Steven Scherer'e, you know, use Google search on the name of Nature in the crew area, and the creationist blogs, forums, viewed through the eyes of the hero that he could ask the scientist is irrelevant. According to legend, Steven Scherer, Zacharia Sitchin'e croaker, about 223 genes, "It is a jump that's not does follow current evolutionary Theories", ie, "current theories of evolution in a noncontiguous jump" found in the interpretation. We had a language that no bones! Now I do regret dediklerinden probably due to a thousand.

A more detailed analysis, this protein synthesis 113'ünün genes in bacteria is a common, multi-celled, but had discovered the only vertebrates suggests.In this paper, these findings as a possible cause of horizontal gene transfer from bacteria to people, a transition in the opposite direction is more likely to be stressed.
Okay so far in such a scientific study of how the Creationists material is the subject of this section is really interesting.
At this stage a person is eccentric to the stage by Zacharia Sitchin. Zecharia Sitchin (d.1922), a writer of books describing the people astronotlarla alien origin.Sitchin, "Annunaki" (or "Nephilim") called for the creation of an ancient Sumerian culture, Solar System, the unseen aliens from the planet Nibiru long and is based on an elliptical orbit circulating suggests. Sitchin'in these opinions as natural scientists, archaeologists and historians yalanlanıyor.
Sitchin "The Case of Adam's alien genes" (the subject of Adam alien genes) in an article by the International Human Genome Sequencing Consortium, 223 found by the original gene, genomic evolutionary tree does not belong to any type of horse says, and as a result of these genes Adam argues that the human species began passing by aliens. Sitchin'in creationists and intelligent designers find this message, blogs, and sites in the issue immediately by moving the event that the bankruptcy of evolutionary theory and human evolution dayandırıyorlar is designed independently.
Easily escape from the eyes detail in this case is an interesting contrast to the claim that the Sitchin'in the original article, a consortium of people that is almost impossible to emphasize that bacterial gene transfer. The article in question from bacteria to human genes is more likely to be emphasized in the past. Thus, even this "alien" to human gene directly contradicts his saçmalığıyla a proposition directly.
After publication in the journal Nature, some researchers will compare a comprehensive data base for the International Human Genome Sequencing Consortium is not controversial, he cited the results. International Human Genome Sequencing Consortium nearly three months after publication, in May 2001, Rockville, Maryland, "The Institute for genomic Research (TIGR)" (Institute for Genomic Research), says a new study. Researchers during the evolution of bacteria by human beings as a relative (if the elapsed) showed very few genes may be in the past. Human, according to analysis of the genomes of bacteria and invertebrates, vertebrates gene in less than 50 people, in a certain period during the evolution of bacteria in the past may be, towards the end of an article published in Science Express, the magazine reported in May 2001.
Researchers have none of these genes directly from bacteria to human being is not possible in the past, whereas some proteins in bacteria are found only in humans and no pretense to be the cause of these genes in invertebrates and invertebrates due to mutations in the human and bacterial genes with saptanamaması announced.
Steven L. TIGR'de head of bioinformatics Salzberg "My friends and I have therefore called for transfer in humans of a bacterial gene could not find any. International Human Genome Sequencing Consortium, using the data described by 41, according to the Celera data, we found the 46 genes shared by humans and bacteria but did not find these genes in invertebrates crawl," he says, and adds, "But we can not claim that this passage of horizontal gene sharing."
In nature, horizontal transfer of genes between species is a phenomenon well-documented. Other bacteria, the bacteria can pass the gene, and also of human cells and organelles mitochondria were once free-living bacteria and in this way people spent their genes.
However, many evolutionary biologists, the way bacteria could pass genes in vertebrates say there is a strong evidence. Therefore, the Human Genome Sequencing Consortium, more than a hundred human proteins "pre-vertebrates or vertebrate species, from bacteria are passed horizontally" in the journal Nature was the big news proposition.
TIGR broadcast, horizontal transition is at least a huge exaggeration, and this thesis showed that it is possible to being completely wrong. On the other hand, no bacteria in vertebrates is currently impossible to prove whether the genes in the past. Instead, TIGR researchers, the available genomic data of the Nature article, tried to support the original description.
As authors of the Nature article, TIGR researchers also unusual species 'distribution traces' bioinformatics tools used to search for. This strategy involved the detection of sequences similar to different types. Salzberg "Array gereçtir strong resemblance, but must be very careful when using," he continues, "Similarity of two proteins is possible that a common ancestor and shows that the functioning of proteins similar to, but does not say when they left."
TIGR'den Jonathan Eisen, says this approach is effective but is often misleading. Unusual distribution traces, or the fact that the loss of existing genes, but as recognition kayıpmış seem to be mutated may be due. Eisen, "the greatest evolutionary problem of the original study, the loss of genes that invertebrate varsaymasıdır" he said, and "the loss is very common, especially in small genomes gene studies have hundreds if not thousands of envisioning" he added.
Accuracies misleading way to a World Cup qualifier, more data bulundurmaktır example. According to the publication Nature, the human genome predicted protein sequences of four invertebrate sequence and the arrays were compared with other invertebrate eukaryotes. These four invertebrate species, yeast, worms, flies and Arabidopsis plants, respectively.
The other hand, TIGR data set, open to the public genomic data, including hundreds of invertebrate species found partial genes, almost all involved. Researchers "Nature reported the team is not the original set of genes, 21 tenesinin sponge invertebrates, soybeans, and marine invertebrate organisms were detected as the parent," announced. Salzberg, "where you can only omitted the result is that the initial study of these genes," he said. Therefore, the re-analysis, the number of genes in the human gene was detected bacteria is said, to compare the human genome is dependent on how many invertebrates have shown that the genome scanned.
Researcher says Eisen, "The origin of the human genome of bacteria had been having a few hundred genes, even if the human genome has 25,000 genes, ie, Nature of a billion years to 600 million during the race the team entered the vertebrate can be found which would have been a part of one per cent of the genome", and adds, "To tell you the truth, this number is a number that is not so interesting."
So what happened to Steven Scherer'e, you know, use Google search on the name of Nature in the crew area, and the creationist blogs, forums, viewed through the eyes of the hero that he could ask the scientist is irrelevant. According to legend, Steven Scherer, Zacharia Sitchin'e croaker, about 223 genes, "It is a jump that's not does follow current evolutionary Theories", ie, "current theories of evolution in a noncontiguous jump" found in the interpretation. We had a language that no bones! Now I do regret dediklerinden probably due to a thousand.
