Evidence of Evolution

Modern Whales Evolution supports: homologous structures, transitional organisms, DNA

Whale Evolution Project Homology Bone structures like many in mammals Compared to ungulates

Whale Limb Homology

Ancestry of Modern Whales Are Whales more closely related to perrisodactyls (odd toed ungluates) or artiodactyls (even toed ungulates)

DNA Comparison – base pair differences DNA comparison of gene for beta-casein milk protein

Pakicetus – common ancestor of ungulates and Whales – 54 million years Ambolocetus
