从分子进化看人类起源

Human′s Origin Studied In Molecular Evolutlon

ＵＰＧＭＡ法，近邻关系法，及最节省法等证明，人类与黑猩猩属于同一进化枝，人类起源的年代远远短于原来的估计．

Human and chimpanzee belong to a same clade, which has ben shown by UPGMA, nei ghbors relation and maximun parsimony methods. So, the divergence time between Human and ape will be as recent as 5 million years ago, rather than a minimum date of 15 million years ago as was commonly accepted by paleontologists.
