you couldn't have possibly posted this at a better time! :D Thanks

Thanks so much for giving such clear definitions and examples. Very enjoyable and I'm sure this was a lot of work to do. Great job!

I love it man, not enough people learn this stuff, i know from experience due to being taught creationism as a child. Thanks for putting your knowledge to good use

I was just thinking that many dinosaurs moved to bipedalism as well, but their "hands" atrophied and eventually disappeared, as such, in the birds. The larger relative size of the brain, perhaps the space that had been used to calculate where they needed to go when using them as legs/feet, perhaps was freed up for the novel mode of manipulating and carrying.

Gibbons/Siamangs should be on your chart next to orangutans.

Why is our last common ancestor with chimps dated some 12 MYA in your chart? That should be not more than 8MYA

this was in my history book in middle school.

In monophyletic taxonomy that uses nested hierarchies, if Platyrrhini are New World Monkeys than Catarrhini has to be defined as Old World Monkey and not Cercopithecoidea alone. Since Cercopithecoidea and Hominoidea are the daughter clades of Catarrhini than both must be defined as "monkeys", meaning that "Apes" are a subgroup of "monkey". Otherwise you are skipping sections of the lineage. You are always of the clades of your ancestors, so apes, including apes of genus Homo are Catarrhini (Old World Monkeys). This is in contrast to the older polyphyletic model of only defining Cercopithecoidea as "Old World Monkeys". In short, Hominoidea are a subgroup of "monkeys" if both their mother clade Catarrhini, and their aunt group Platyrrhini are considered "monkeys". "Apes" are "monkeys".
