International human genome sequencing consortium describes finished human genome sequence
...sts have identified more than 1,000 new genes that arose
in the human genome after our divergence with rodents some 75 million years ago. Most of these arose
through recent gene duplications and are involved with immune, olfactory and reproductive functions....
Laboratory test of evolutionary theory confirms importance of links between populations
...he researchers were able to track adaptations that arose
in both bacteria and virus populations and show that the pattern of adaptations depended on both the environment in which the organisms were growing and the spread of genes between different populations. Ecologists use the term "gene flow" to descri...
Of lice and men
...Like the replacement theory, it says modern humans arose
in Africa and spread across the world, Rogers says. Like the multiregional theory, it says those early humans mated with humans elsewhere. The diffusion wave theory adds a new twist, namely, that the genes of humans spreading from Africa came to domi...
