IIRC a "hypothesis" is an educated guess supported by the available
evidence. It is useful so long as it continues to be tested against new
evidence. For example there is quite a bit of evidence that supports the
hypothesis that man has been cooking for 100,000 years or so. However,
there is not enough evidence to come up with a testable theory as to
when and why cooking began. As an interesting aside, *all* cultures
cook, and *all* cultures also have traditional dishes that include
fresh, raw flesh. This just further confounds the issue.
I am sympathetic to your cause, but I have a knee jerk reaction to your
tactics. Just because you can come up with alternate explanations for
individual bits of evidence doesn't change the fact that the evidence
*does* support the hypothesis that was presented. So, to the uneducated
ear an alternate explanation for burnt bones casts doubt on the whole
theory of early man's cooking habits, but it is *bad* science. To make
the science better you would need to come up with a single hypothesis
which could explain all (or at least a majority) of the available evidence.
The difficulty is that it is tough to prove the negative. It is easy to
prove that men in all cultures have been cooking for all of recorded
history. It is very difficult to prove what they did before then.
Cooking destroys its own evidence. In addition I would offer that your
own explanation for the burnt bones, destroying food to avert predators,
is a better explanation for why men wouldn't leave behind evidence of
their cooking. It is common practice for nomadic people to pack out or
bury evidence of their passage to avert enemies and wild predators. Join
the Army and they'll teach you how it's done ;-) Seems more likely to me
that evidence of cooking would be found with sedentary or semi-sedentary
peoples. However, this doesn't preclude nomadic people cooking. Just
makes it hard to prove either way.
