Chimp and human: Why different?

Human and chimpangees share 97% gene homology. The question then was why are they so different from each other.


In a study published in Proceedings of the National Academy of Sciences an attempted has been made to answer this dilemma.


The researchers found that 90 transcription factors which affect 1,000 genes may be behind this. There are differences in these transcription factors in both human and chimps. Thus they differe in control of gene regulation.

This leads to difference in gene expression in both species and thus both human and chimps become different.
