If man is so less suited physically in terms of strength, speed, agility, etc. to survive in the same environment as apes, or other hominids, then how would the fledgling species have managed long enough to discover firs and use it to enhance his survival? It doesn't seem reasonable that the discovery of fire alone could account for man's survival with so much else against him. Nor does it make sense that there would have been an evolutionary advantage for man to develop as he has.

Well, I never said that humans were less suited to particular environments than the other apes. Obviously, they were, since they survived and prospered.
Fire is not a real factor, in my opinion. It was useful to humans, certainly, but nobody really knows which of the hominid species first used it.
Tool-making is more of a factor.
firs=fire
Spell check doesn't catch it if it's spelled right. *sigh*
