Alex I think there is something to that - supposedly forensics can look at a skull and tell if it belonged to a Caucasian, an African, or an Asian. That has always flummoxed me, like how TV works. I don't understand it at all.

History is kind of a funny thing. We have documented facts about a lot of things, and taking that into account, one would assume that these things might not be disputed. But they are. We like to cuss and discuss about what the documented facts actually mean and whether they're even true or not. Sometimes we find out they're not, when an exciting new discovery is made. Then maybe 50 years down the road, we find something else that makes the first discovery obsolete.

It's a never-ending process.
