Anthropological evidence confirms that all people originally came from Africa

I don't really have a problem with this idea, but I think it is a simplification that some more learned than I on the subject may contend. The anthropological evidence on which all these theories are based - still remains very scarce and every time there is some more evidence found - there are yet more theories.

But it rather depends how far back in the earth's past you wish to go. There was a time when there was no African continent - just one big one continent where all our ancestors existed together - in some form. Or if you want to go even further back - existed together in the sea itself....It all seems to lead back to the sea in some way.
