Any to suggest that the third human on this planet did NOT COME from the first two.. is to concoct an interesting yarn of science fiction.. There is zero evidence that any form of "human" was not as intelligent as the current ones.. -OR- depending on how cynical you are..... just as dumb..
I think that you missed my point entirely.
I agree with that statement, dear hosepipe. Yet you know as well as I do that evolutionary theorists just EXPECT that man MUST be getting BETTER over time. Meaning: smarter, more "fit," etc. That means past (dead) generations before our own were less smart, less fit, etc., etc., than we who are presently living.
I mean, isn't evolution all about "progress" while at the same time denying any purpose in nature? And yet: How can there be "progress," if there is no purpose, criterion, or standard to assess "progress" by in the first place?
