Human Evolution Was Driven By The Genetic Mutations And The Genes That Repressed Them

Humans came to be after millions of years of conflict between genes that mutated and those that repressed their mutation. "We have basically the same 20,000 protein-coding genes as a frog, yet our genome is much more complicated, with more layers of gene regulation," said Sophie Salama, a research associate at the University of California, Santa Cruz, Genomics Institute, where researchers are studying the complex processes of human evolution.
