But the human neocortex has accumulated about three times more lipid
changes than the chimpanzee cortex has since we split from our common ancestor.
Not exact matches
Because Neandertals are much closer kin to us
than are
chimpanzees, which diverged from the human lineage 5 to 7 million years ago, matching Neandertal DNA against our own has the potential to reveal genetic
changes that help define who we are.
By studying the muscles of bonobos (which indicates how they physically function), the team was able to discover that they are more closely related to human anatomy
than common
chimpanzees, in the sense that their muscles have
changed less
than they have in common
chimpanzees.
Furthermore, by comparing the patterns of
change in humans and
chimpanzees, it was revealed that HAR - associated schizophrenia genes were under stronger evolutionary selective pressure
than other schizophrenia genes.
So, on average, the genes from humans and
chimpanzees changed faster
than genes from monkeys, which
changed faster
than those from mice.
October 17, 2013 Gene regulation differences between humans and
chimpanzees more complex
than thought
Changes in gene regulation have been used to study the evolutionary chasm that exists between humans and
chimpanzees despite their largely identical DNA.
The vast differences between humans and
chimpanzees are due more to
changes in gene regulation
than differences in individual genes themselves, researchers from Yale, the University of Chicago, and the Hall Institute in Parkville, Victoria, Australia, argue in the March 9, 2006, issue of the journal Nature.
