Humans share 95% of our genome with chimpanzees, new study shows

Summary

Nutrition label

85% Informative

UC Santa Barbara researchers found differences in gene expression between humans and chimpanzees.

They measured gene expression by observing the amount of mRNA a specific gene produced in humans, chimpanzees and macaques.

They found that many of our genes are much more productive than those of other primates.

Among glial cells, oligododcytes showed the greatest differences in the expression of gene expression.

Yi plans to study the mechanisms behind differences in gene expression and how genes map to different traits.

She plans to trace differential gene expression even earlier in our evolutionary history by incorporating baselines from even more distantly related animals.

And she’s interested in studying genomic differences between us and Neanderthals and Denisovans .
