The five Ages of humankind - a potential timeline. The myths surrounding the ages of humankind suggest the first was the longest, and the best. The next was shorter, and a little unsettling. And so on.
So, extrapolating from a few well known events in human history, we can make a bit of a guess as to these events and the timelines of the ages. Perhaps.
10,000 years ago - end of last ice age. Homo floriensis becomes extinct.
x4 40,000 years ago - modern day humans out of Africa, extinctions of purebred Neanderthals and Devisonians
x5 200,000 - appearance of first modern day humans in fossil record
x6 1,200,000 - Homo erectus and Homo ergaster were the first of the hominina to leave Africa, and these species spread through Africa, Asia, and Europe between 1.3 to 1.8 million years ago.(Wikipedia)
x7 8,400,000 - 7 Ma Hominina speciate from the ancestors of the chimpanzees. Both chimpanzees and humans have a larynx that repositions during the first two years of life to a spot between the pharynx and the lungs, indicating that the common ancestors have this feature, a precondition for vocalized speech in humans (Wikipedia)
