kri don t tell a biologist he doesn t know about biology if humans were as old as cremo says they are then humans would have had vertebral columns before the earliest forms of segmentation arose humans would have had fingers before anything else had fins humans would have had kidneys before anything else had protonephridia and humans would have had well developed endoskeletons before anything else had notochords the suggestion that humans could have had derived features before those features existed in their most primitive forms is absurd furthermore cremo s proposal would have humans living on an earth whose atmosphere they couldn t even breathe also the genetic distance between humans and chimps and bonobos goes a long way towards establishing our place in the tree of life cremo s bullshit has no place in this article we shouldn t pretend that cremo s war on reality is anything more than creationism
