Positive Selection on Genes in Humans as Compared to Chimpanzees
نویسندگان
چکیده
Positive selection has been identified and extensively studied in many human genes. In contrast, positive selection in the closest human relative, chimpanzee, has been largely unstudied until recently.With the complete sequencing of the human and chimpanzee genomes, a comparison of the types and numbers of genes that underwent positive selection in the two species is possible. The types of genes under positive selection in human and chimpanzee are different with regard to gene function, but no particular type accounts for a large part of this difference. However, significantly more genes experienced positive selection in the chimpanzee lineage than in the human lineage.

Natural selection on the olfactory receptor gene family in humans and chimpanzees.
The olfactory receptor (OR) genes constitute the largest gene family in mammalian genomes. Humans have >1,000 OR genes, of which only approximately 40% have an intact coding region and are therefore putatively functional. In contrast, the fraction of intact OR genes in the genomes of the great apes is significantly greater (68%-72%), suggesting that selective pressures on the OR repertoire vary...
متن کاملSimilar numbers but different repertoires of olfactory receptor genes in humans and chimpanzees.
Animals recognize their external world through the detection of tens of thousands of chemical odorants. Olfactory receptor (OR) genes encode proteins for detecting odorant molecules and form the largest multigene family in mammals. It is known that humans have fewer OR genes and a higher fraction of OR pseudogenes than mice or dogs. To investigate whether these features are human specific or co...
متن کاملThe difficulty of avoiding false positives in genome scans for natural selection.
Several studies have found evidence for more positive selection on the chimpanzee lineage compared with the human lineage since the two species split. A potential concern, however, is that these findings may simply reflect artifacts of the data: inaccuracies in the underlying chimpanzee genome sequence, which is of lower quality than human. To test this hypothesis, we generated de novo genome a...
متن کاملHuman SNPs reveal no evidence of frequent positive selection.
We compared the single-nucleotide polymorphisms (SNPs) in humans in 182 housekeeping and 148 tissue-specific genes. SNPs were divided into rare and common polymorphisms based on their frequencies. We found that housekeeping genes tend to be less polymorphic than tissue-specific genes for both rare and common SNPs. Using mouse as a second species for computing sequence divergences, we found no e...
متن کاملImplications of natural selection in shaping 99.4% nonsynonymous DNA identity between humans and chimpanzees: enlarging genus Homo.
What do functionally important DNA sites, those scrutinized and shaped by natural selection, tell us about the place of humans in evolution? Here we compare approximately 90 kb of coding DNA nucleotide sequence from 97 human genes to their sequenced chimpanzee counterparts and to available sequenced gorilla, orangutan, and Old World monkey counterparts, and, on a more limited basis, to mouse. T...
