"We ca n't be of the same kind as apes , because ( based on the only `` definition `` of kind I 've heard ) micro-evolution can turn one species into another within `` kinds `` , and humans ca n't turn into anything , or vice-versa ."
"So we ca n't base our definition of `` kind `` on mere appearances ? I mean if we are going to put things into categories and call the category `` kind `` , we should do this by common appearances . A penguin is in the same kind as a hummingbird , but is a lobster in the same kind as an oyster ? Obviously a lobster and a shrimp would be in the same kind , but could a dolphin and a manatee be in the same kind ? Did they evolve from a common ancestor kind ? And since apes look and act so much like humans , did n't they just evolve from humans ? By all appearances , they we must all be in the same kind ."
