MadSci Network: Evolution |
Wow, what a question! Unfortunately, I can give no definitive answer. The reason being for one, is that the line between human and non-human is blurred, and people have different definitions as to what is and is not considered human. Take a look at our partial family tree, gleaned from the fossil record thus far: http://www.mnh.si.edu/anthro/humanorigins/ha/a_tree.html There has been several new discoveries since this chart was made, but as there is still controversy as to where they belong in this framework, this will have to do for now. So firstly, when you ask "Who was the first (hu)man?" we're in a quandary. Are all of the species listed above considered human? Does humanity begin with the genus "Homo"? Do we draw the line with the first Archaic Homo sapiens or only include those individuals who fit into our own classification of Homo sapiens sapiens? If we draw the line at Homo sapiens sapiens, then the first "Human" existed, according to current data, in Africa and/or Southwest Asia around 115,000-96,000 years ago, and would probably have been similar looking to the people who live in those places now. We're not sure which of these places, if either, gave rise to the first Homo sapiens sapiens, because the fossils from these areas overlap in their possible age ranges. To further complicate matters, it is highly unlikely the "first human" 's remains are even preserved. The chances are more likely than not that they decomposed, as only a small percentage of life forms become fossils. Long story short, no one knows, or will ever know what the first person really looked like because no one can agree on what is or is not a human and the fossil record is not complete enough to be certain about any guess.
