Results from the human and chimpanzee genome analyses should help in understanding some human diseases. Humans appear to have lost a functional Caspase 12 gene, which in other primates codes for an enzyme that may protect against Alzheimer's disease. Human and chimpanzee genomes. M stands for Mitochondrial DNA
The DNA that is present in today's gorillas diverged earlier from the DNA that is present in today's humans and chimps. Thus both loci should be more similar between human and chimp than between gorilla and chimp or gorilla and human. In the lower graph, locus A has a more recent common ancestor in human and gorilla compared to the chimp sequence.
The earliest fossils clearly in the human but not the chimpanzee lineage appear between about 4.5 to 4 million years ago, with Australopithecus anamensis. Few fossil specimens on the "chimpanzee-side" of the split have been found; the first fossil chimpanzee, dating between 545 and 284 kyr (thousand years, radiometric ), was discovered in Kenya ...

Evidence for the evolution of Homo sapiens from a common ancestor with chimpanzees is found in the number of chromosomes in humans as compared to all other members of Hominidae. All hominidae have 24 pairs of chromosomes, except humans, who have only 23 pairs. Human chromosome 2 is a result of an end-to-end fusion of two ancestral chromosomes ...
Comparing a given gene with that of other species enables geneticists to determine whether it is rapidly evolving in humans alone. For example, while human DNA is on average 98% identical to chimp DNA, the so-called Human Accelerated Region 1 , involved in the development of the brain, is only 85% similar. [2]
A draft version of the chimpanzee genome was published in 2005 and encodes 18,759 proteins, [28] [29] (compared to 20,383 in the human proteome). [30] The DNA sequences of humans and chimpanzees are very similar and the difference in protein number mostly arises from incomplete sequences in the chimpanzee genome.
After a recent study conducted at the University of California, humans may now have a glimpse into the answer to that age old question. Scientists discover that just 7% of human DNA is unique to ...
