Fast-Mutating DNA Sequences Shape Early Development; Guided Evolution of Uniquely Human Traits

Researchers at Gladstone Institutes, University of California have looked at the connection between humans and chimps and what regions of dna they differ in. They had found that there are regions where the mutation rate for humans and chimps vary. These sites are called human accelerated regions (HARs). In humans, there were over 2600 of these sites, of them, it was deemed that about 100 of them had a very fast mutation rate in comparison to the other regions. They have decided that these 100 will be watched closely in future research. This technology has the posibility to pave the way for controlling human evolution.
