Chimp and human Y chromosomes evolving faster than expected Date: January 15, 2010 Source: Whitehead Institute for Biomedical Research Summary: The first comprehensive comparison of Y chromosomes ...

After comparingthe Y chromosome sequences of the human and chimpanzee, Howard HughesMedical Institute researcher David C. Page, postdoctoral fellowJennifer F. Hughes and their colleagues have seen ...

The human and the chimpanzee Y chromosomes went their separate ways approximately 6 million years ago. But ever since this evolutionary parting, these two chromosomes have experienced different fates.

The human and chimpanzee genomes are 99% similar. HARs make up a big portion of the 1% difference, which can lead to dramatically different outcomes in human and chimp neurons in petri dishes.

First, the banding (or dye pattern) of human chromosome 2 closely matches that of two separate chromosomes found in apes (chimp chromosome 2 and an extra chromosome that does not match any other ...

Since 2010, scientists have known that the Y chromosome is rapidly evolving in humans, but a new study shows that the same can be said across all Great Apes—the closest relatives to humans.

For example, the X chromosomes of humans and chimpanzees are about 98 percent identical in makeup. On the other hand, only about one-third of the Y chromosomes of the two species matched.
