Brain Candy as Tiger Milk
Observation: the human brain appears able to use lactate as fuel instead of glucose during strenuous exercise (see Science Daily). Deduction:
From an evolutionary perspective, the result of this study is a no-brainer. Imagine what could have or did happen to all of the organisms that lost their wits along with their glucose when running from predators. They were obviously a light snack for the animals able to use lactate.
This gem was from Gerald Weismann, editor of the FASEB journal in which the study was published. Weissmann did not explain why humans didn’t evolve some means to circumvent this threat of becoming crunchy brain candy to tigers – a little hot sauce surprise in the cerebellum, perhaps. But then, it would be tough for the victim possessing that innovation to pass on his genes. Presumably one can only “imagine what could have or did happen” when one loses his wits.
This is the same Gerald Weismann that won SEQOTW two months ago for updating Darwin with On the Origin of Tumors by Natural Selection (08/13/2008). This time, Weissmann was absolutely right. From an evolutionary perspective, it was a no-brainer.
