One Perspective

Although it has commonly been stated in the past that humans and chimpanzees have 98.5% DNA similarity, this figure has recently been found to be incorrect. Newer research has suggested that there is approximately 96% genetic similarity between Humans and chimpanzees overall.

Of course the fine details depend on what specific chromosomes one is looking at. Although 96% of the DNA is similar overall, there are some very significant differences in some chromosomes, where other chromosomes are nearly identical. Specifically, 18 of the chromosomes of humans are nearly identical to those of chimpanzees, the rest are very different (eg: chromosomes 4, 9, 12, 21, and y).

Some specific examples of differences include:

1) Humans have 23 pairs of chromosomes in total while chimpanzees have 24.

2) Chimpanzees and other apes have telomeres about 23 kilobases long, whereas humans are completely unique among primates with much shorter telomeres only 10 kilobases long.

3) The Y chromosome in chimpanzees is smaller than that of humans and only 60% of the genes are similar to those of the y chromosome of humans.

Another Perspective

It really depends on what we are comparing - the entire genome or just the small fraction (1%) which codes for proteins. If we compare the ENTIRE genome to another then the figures for similarity are very low and in fact, such a study has not been done. If we compare the similarities between the genes that code JUST FOR PROTEINS (1% of entire genome), then the figure is very high! The vast majority of mammalian DNA does NOT code for proteins - it was once believed to be "junk DNA" with no function - Now we know this assumption was totally wrong. We now know they play an important role in preserving the genome itself - and many other functions as well.

What percentage of DNA do humans and mushrooms share?

very interesting, You know, Iโ€™d like to know what percentage of DNA Chimps share with mushrooms? If less, then are we really just Chimps that ate a bunch of mushrooms (likely hallucinogenic, repeat offenders over centuries?). Itโ€™d explain why we share so many of the same viruses that fungi have. Why fungi (penicillin) has saved our lives. Why our brains work the way they do.... mycelium? Itโ€™s a fun thought, for sure. But, Iโ€™d love to see more research done in the field of mycology... Could that save humanity? heres a mycologist working on the mystery of the mushroom. Future smart kids of the world, consider this field. This should be funded as big as NASA. do your research on this guy, Paul Stamets. Think for yourselves. Be good to each other. -Nate

Orang utans share 96.4% of their DNA with us and Chimpanzees share 98.5% of their DNA with us humans... who knows there might be a type of primate out there that has not been discovered yet that shares more of their DNA with us the Bonobos.

The high degree of similarity between chimpanzee and human DNA suggests that?

Humans and chimpanzees share 94% of the same DNA. By comparing certain genes of chimpanzees to those of humans, scientists can tell the approximate number of generations since humans and chimpanzees shared a common ancestor. It is believed that the ancestors of humans and chimpanzees diverged between four and six million years ago. In other words, it is support for evolution and the fact that humans evolved from great apes.
