DNA CHIMPANZEE VS HUMAN SOFTWARE

The DNA sequencing of the chimpanzee was performed by Celera Genomics, in Rockville, Md., as part of a larger study of human variation headed by company researchers Michele Cargill and Mark Adams.Ĭelera generated some 18 million DNA sequence 'reads,' or about two-thirds as many as were required for the first sequencing of the human genome. 'It is a treasure-trove of ideas to test by more careful comparison of human and chimpanzee development and physiology,' Clark says. 'But we found hundreds of genes showing a pattern of sequence change consistent with adaptive evolution occurring in human ancestors.' Those genes are involved in the sense of smell, in digestion, in long-bone growth, in hairiness and in hearing. Clark, Cornell professor of molecular biology and genetics. 'Human and chimpanzee sequences are so similar, we were not sure that this kind of analysis would be informative,' says evolutionary geneticist Andrew G.

In the most comprehensive comparison to date of the genetic differences between two primates, the genomic analysts found evidence of positive selection in genes involved in olfaction, or the ability to sense and process information about odors.

12, 2003), found these and many other differences in a search for evidence of accelerated evolution and positive selection in the genetic history of humans and chimps. Specifically, two key differences are how humans and chimps perceive smells and what we eat.Ī massive gene-comparison project involving two Cornell University scientists, and reported in the latest issue of the journal Science (Dec. Nearly 99 percent alike in genetic makeup, chimpanzees and humans might be even more similar were it not for what researchers call 'lifestyle' changes in the 6 million years that separate us from a common ancestor.

They filmed the apes and monkeys in their natural habitat and then used sports analysis and statistical software to analyze their movements.ITHACA, N.Y.

It became clear to researchers that downclimbing was a “highly important factor in the diverging anatomical differences between monkeys and apes that would eventually manifest in humans.” Before the discovery of fire, early humans climbed into trees at night for safety, only coming down at dawn.īy looking at the climbing habits of chimpanzees and sooty mangabeys, the researchers compared climbing styles and descent mechanisms. “When downclimbing, not only am I putting muscles under contraction that are probably used less, but unless I am fully lowering myself to a hanging position, that contraction is also placing increased stress on the joints of my upper arm.” Comparing downclimbing styles “I started to think a lot more about how tiring downward movement over steep slopes could be and how much I needed to adapt my movement specifically to deal with the stresses it would place on my quads, hips, and knees,” Joy told UK Climbing. Joy is a climber and watching the chimps descend reminded her how taxing downward movement is on the body, both while climbing and mountain running. While watching chimpanzees, researcher Mary Joy was captivated by the downclimb.
