Want to see what Colby looked like 600,000 years ago? A quick trip to the Museum of Natural History in DC and voilà! It's a hell of a lot cheaper (and scientifically reasonable) than jumping in a time machine. Watch Colby Homo sapiens sapiens morphing into Colby Homo heidelbergensis. A likely ancestor of Neanderthals and Homo sapiens, Homo heidelbergensis made tools, perhaps used language and very likely buried its dead-- the first hominid to display ritual behavior.
