Comparative Genomics of extinct &extant groups

Present DNA technological approaches have progressed in such a way that we have been able to find homologyamong organisms and trace for evolutionary mechanisms even for a fate of a few nucleotides and also analyze the path and time of evolutionary deviations among different organisms. Not only based on anthropological point of view, but also from the homology of DNA sequences we have proved that Homo sapiens arose after hybridization in between two species of Homo. Furthermore, detailed investigations on DNA isolated from the fossil bones .biologists and biochemists have introduced modes of origin of Neanderthal and other Homospecies including Homo sapiens.
