Norsemaiden said:Freezing temperatures were not good for individuals in the Ice Ages. But for the species - that is for the descendants of those who survived - the frigid weather was a benefactor. Parents didn't have to worry that their daughters would mate with worthless young men. When nature gets rough, there are no worthless young men! From the standpoint of eugenics, the hostile climate raised the intelligence level of the survivors' descendants sufficiently to pave the way for civilisation.
I'm sorry but there are a number of false claims in this excerpt alone. For one no scientist can state a factual claim as "the cold weather was a benefactor" - first of all it's an assumption, 2nd is it's a crappy assumption. There may have been some advantages to the colder climates, but weather kills and acts indiscriminately; and the fact that neanderthalensis was the only being adapted enough naturally to survive "ice age" weather says a lot about how much of a "benefactor" it was to normal homo sapiens; the fact was that even with there benefits they could not survive with the climate the way it was without a strong shelter and a supply of food which are hard to come by in a scarce landscape.
Another thing...parents ALWAYS have to worry about worthless young men (and women). Although the intelligence of a being is important, so is the raw physical strength and abilities of one. Power can always replace intelligence if intelligence is not cultivated and used in the correct context (and vice versa). Just because the climate was rough does not mean that the best of the best were only allowed to breed, and hostility does not raise the intelligence of people. And I have to mention that although many throw civilization around as if it was culture, it is not the same thing. Even if many ice age humans (near the end of the ice age anyway) had banded together and created a society, the first recognized civilizations were in Egypt and Mesopotamia. This however does not mean that it is safe to assume there were no concepts of culture back then and that there weren't any smaller civilizations either; the ones recognized had to have had an origin somewhere.
Norsemaiden said:Some of the near relatives of Heidelberg Man, whose remains were found only 100 miles south of the furthest extension of the ice sheet, must have lived through the 40,000 year Mindel Glaciation.
The Heidelbergensis fossil was found in germany which was on the rim and somewhat (but not very far inward) of Germany. not to mention that Heidelbergensis man was just a damn jaw bone that may have been a missing link to relate homo sapiens to homo neanderthalensis, however if I remember a recent genetics test seemed to say neanderthalensis was of a different lineage than homo sapiens; and heidelbergensis was shown more to be an ancestor to neanderthalensis than homo sapiens due to the structure of the jaw bone and theoretical occipital bun.
Norsemaiden said:"It took three more Ice Ages, the Riss Glaciation and Wurm I and II to raise the inventive quality to the level that resulted in the New Stone Age, when tools were made more expertly and in greater variety."
What tool ages are you even referring too? Auschelian (spelling?) was common among hominids before neanderthalensis (Homo Nean used mousterian tools themselves); and humans depending on what region you are looking at got all the way up to the magdalenian era which was boats and bows and arrows. prior to that the chattelperonian was common to many regions - of course the magdelinian era came far after the extinction of neanderthalensis. To just say "tone age tools" is vague
