Rapid evolution of male reproductive genes in the descent of man

摘要: A diverse body of morphological and genetic evidence has suggested that traits pertaining to male reproduction may have evolved much more rapidly than other types character1,2,3. Recently, DNA sequence comparisons also shown a very high level divergence in reproductive proteins between closely related Drosophila species4,5,6, among marine invertebrates7,8 mouse rat9. Here we show rapid evolution genes is observable primates quite notable the lineages human chimpanzee. Nevertheless, by itself not necessarily an indication positive darwinian selection; relaxation negative selection often equally compatible with data. By taking three statistical approaches, driving force behind this evolution. These results open up opportunities test hypothesis sexual plays some role molecular higher primates.
