65 Million Years ago. The Mass extinction, out of Yucatan and the beginning of
Mammals. The Mass extinction was caused by a comet striking The Yucatan peninsula of
what we call Mexico. Some say the effects of the Comet earth cover was added to by
considerable volcanic activities on what we call the Indian Plate.
About Mammal development; (1) It took about 3,500,000 years to go from first ape like
man to the Stone Age. (4 mill to 700,000).
Present evidence tells us the Australopithecus Africanus (kind of looking like us) are of
this time period.
(2) The archeological studies of the Neanderthal indicate it was on earth some 380,000
years. It was separate and distinct, from all the other varieties. The best evidence is that
its brain size was comparable to Humans, but its body was not built for speed. Its torso
was shorter and squarer.
The face was much flattened at the forehead. It had reddish hair, which covered the body
much more than humans. We do not know if this hominid had language, but it did leave
some art in the form of stone tools and cave drawings.
(3) Archeological findings place the first evidence of Look-a-likes somewhere between
200,000 and 150,000 years ago. These finds are of a smaller brained kind, non-beer
drinker. Probably 45 hp vs.
our 540 hp. They could have had language, but who knows.
(4) Modern Human, with its many variants (Caucasian, Negroid, Asian, and lesser in
numbers such as Indian, Australian native etc.) has been identified as here for
approximately 40,000 years. The term Homo sapiens (or Modern Human—wise man) is
keyed to the finding of a larger brain size (1350 cc) in a lighter built body. This seemed
