He says this idea has «very profound» implications for the debate over the origins of bacterial genes that are present in the human genome but absent in our closest relatives (Science, 8 June, p. 1903): The amount of conjugation Waters detected is «high enough to readily explain» the possible infiltration of bacterial genesinto our DNA, meaning that conjugation could have happened quickly enough to add genes only to humans, in the years since they split from the common ancestor they
shared with
chimpanzees.
Most researchers believe that humans
shared a common ancestor with
chimpanzees and bonobos between 5 million and 7 million years ago (for a different take, see ScienceNOW, 27 February).

shared with only the bonobo, but not
chimpanzees.

chimpanzees that are close enough to humans to
share 99.6 % of their DNA.
Ever since researchers sequenced the chimp genome in 2005, they have known that humans
share about 99 % of our DNA with
chimpanzees, making them our closest living relatives.
Added to this, our ancestors probably weaned their babies by mouth - to - mouth feeding of chewed food, as
chimpanzees and some mothers do today, reinforcing the connection between
sharing spit and pleasure.
After analyzing human DNA from several populations around the world and examining primate genomes dating back to the
shared ancestor of both humans and
chimpanzees, researchers reached a striking conclusion that several gene variants linked to schizophrenia were actually positively selected and remained largely unchanged over time, suggesting that there was some advantage to having them.
If, as some say, culture is any learned behavior that is
shared by a collective,
chimpanzees easily make the grade.
The team found that ARHGAP11B was also present in Neanderthals and Denisovans, human cousins with similarly sized brains, but not in
chimpanzees, with which we
share 99 percent of our genome — further support for the idea that this gene could explain our unusually large human brains.
«In addition, our study has shown that there is a mosaic evolution of the three species, in the sense that some features are
shared by humans and bonobos, others by humans and common
chimpanzees, and still others by the two ape species,» said Rui Diogo, lead author of the paper and associate professor of anatomy at Howard University.
It also sheds some light on how two species — humans and
chimpanzees — that
share so many genes can be so different.
«Such a mosaic anatomical evolution may well be related to the somewhat similar molecular mosaic evolution between the three species revealed by previous genetic studies: each of the
chimpanzees species
share about 3 percent of genetic traits with humans that are not present in the other

The sequencing of the human genome (ScienceNOW, 14 April 2003:) gave scientists major new insights into what makes us human: Although we
share more than 98 % of our genetic code with the
chimpanzee, natural selection has turned us into a very different animal than the chimps, from whom our hominid ancestors split evolutionarily some 6 million years ago (ScienceNOW, 31 August).
The

Although this provides one of the first glimpses of cooperative understanding outside humanity — and raises the possibility that such abilities might have been present in our common ancestor more than six million years ago — it does not mean that
chimpanzees can communicate about a
shared goal, like human children.

share with
chimpanzees, our closest living relative.
Chimpanzees are our closest living relative, meaning we also
share a very important evolutionary ancestor.
But ancient - DNA sequencing is beginning to shed some light on the issue.11 For example, by comparing a human HAR sequence with the HAR sequence of an archaic hominin, researchers can estimate if the HAR mutated before, after, or during the time period of our common ancestor.12 This approach has revealed that the rate at which HAR mutations emerged was slightly higher before we split from Neanderthals and Denisovans.3, 13 As a result, most HAR mutations are millions of years old and
shared with these extinct hominins (but not with
chimpanzees).
