You didn’t direct your question to me, but I can answer it. Homo erectus was a now-extinct species of the Homo genus, part of the family of hominins. It may or may not have been a direct ancestor of modern man, but it lived on this planet over a million years ago. It may have been one of the first hunter-gatherers (omnivores) in our genus. (Probably not related to Adam and Eve, however, since they were “made from scratch” only 6000 years ago. Yuk, yuk.)
“If pressed about man’s ancestry, I would have to unequivocally say that all we have is a huge question mark. To date, there has been nothing found to truthfully purport as a transitional specie to man, including Lucy, since 1470 was as old and probably older. If further pressed, I would have to state that there is more evidence to suggest an abrupt arrival of man rather than a gradual process of evolving.” 10
