Re: Evolutionary tree showing areas and habitats

Allan Krill

This evolutionary tree includes baboons. Both baboons and humans went from the trees to the ground. The baboon shows a normal evolution, whereas the human shows a weird evolution. I think that is like the ground-dwelling iguana on Galapagos. The tree-dwelling iguana rafted from South America to Galapagos, and was trapped there, with no trees to live in. It adopted a marine habitat, and its body changed dramatically like the human body changed. Then it became ground-dwelling, with a weird body that shows its earlier marine habitat. Read about this iguana on Wikipedia.
