    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 and

    Whenever I see an evolution tree of life I always thought how human centric the shape become... the slope are all leaning to human. I understand that it make sense since it's us who want to know who we are related to and all but still...

    I'm waiting for my back-hair to go silver so I can be the dominant ape in my tribe.

    Why are they called Purgatorius ceratops when they don't have horns on their heads? Ceratops means "horned face".

    Does the genetically determined date of the last common ancestor of chimps and humans come after the date of the 1st fossil of a human? The video seemed to imply that although I may have missed something.

    Humans have stopped evolving, natural selection no longer applies when we no longer live in nature & everyone's genes get passed on, you could have the smartest human ever never breed & pass on its genes while the dumbest has like 12 kids, the strong breed shure but so do the weak, the genetically speaking inferior, with health problems & what not, we've advanced past the point of evolution, at least from a survival of the fittest perspective

    I'm a proud "primate supremecist" and condemn inter-order relationships and breeding - anyone who is mixed-order is just sub-primate! But same sex marriage/relationships within the order is fine. Allow me to introduce my lemur husband, Alvin.
