    Purgatorius, a kind of mammal called a plesiadapiform, might’ve been one of your earliest ancestors. But how did we get from a mouse-sized creature that looked more like a squirrel than a monkey -- to you, a member of Homo sapiens?

    Thanks to Ceri Thomas for the Purgatorius reconstruction. Check out more of Ceri's paleoart at http://alphynix.tumblr.com and http://nixillustration.com

    I recently read an article that says that our last common ancestor might actually be orangutans rather than chimps.

    There's no transition species, humans just appear on the evolutionary time-line.

    I am related to owls. I say this because it is technically true and I like owls.

    Do we have a good idea of what the last common ancestor of homo sapiens and chimps looked like?

    So if we don't have those pads as Hominidaes does that mean that our buttocks are convergent evolution?

    My evolution stretches back to Alan, a bitter old drunk who swore at the television. He never streamed fantastic content like this; thus avoiding the garbage on free to air tv.

    Hang on dont we need to find the missing link before we can say categorically were we fit? As we have seen very recently with the discovery of 210k year old human remains in Greece wich challenges or out of Africa perception or certainly or migration date. That to assume anything in anthropology is to no nothing.

  • Solrod

    I'm confused.Purgatorius was found in North America and it is said to be a human ancestor, and our more recent ancestors appeared in Africa. But I see a map of the world from that time and North America and any means for reaching Africa are just too separated. There were no ships or airplanes back then and I don't think purgatorius could swim such long distances.If purgatorius was from North America and then his descendants that would lead to us were from Africa, how did they reach Africa in the first place? Is purgatorius really our ancestor or it could be another animal we don't know yet?
