Skeletal Heat

On a recent expedition to a remote region of northern Canada, scientists uncovered skeletal remains from about 100,000 years ago. Surprisingly, all the skeletal remains, which included many species from differing biological families and spanned about two thousand years, showed evidence of experiencing temperatures in excess of 1000 degrees Fahrenheit (or 538 degrees Celsius).

Which of the following, if true, best explains the apparent paradox between the cold environment and the evidence of the bones experiencing hot temperatures?

A) Other scientific research released two years before the expedition showed that the remote region of northern Canada underwent considerable warming in the past 100,000 years.
B) Chemical changes that naturally occur during the process of decay in only one north Canadian species produce the same evidence of the species' skeletons being exposed to hot temperatures as the expedition scientists found.
C) A little over 103,000 years ago, a large fire is known to have occurred in northern Canada.
D) Strong evidence exists that as early as 70,000 years ago, Homo sapiens around the world relied heavily on fire to cook animals.
E) In the same expedition and in roughly the same layer of excavation, scientists found rudimentary wood cutting and hunting tools used by early humans.

I don't think this is very representative of a real GMAT question (based on my limited experience so far)

E requires you to assume the fires started with the wood would hit 1000 C

By the same token the "considerable warming" over the past 100,000 years in A could have also baked the remains real good! lets conveniently assume the temperatures over time or at a particular time hit 1000 C to nicely fry the bones....
