There was a scientific article a couple of year ago on this. I can't remember
the publication. It might have been Scientific American. There was also a TV
documentary based on it. Both made the point that the proposed, post-impact
environmental conditions and the duration of the disruption should have wiped
out the amphibians.[ Reply to This | Parent | # ]

Actually, no the chemical reactions that drive the muscles do NOT slow down.
They change COMPLETELY. One metabolic pathway shuts down, another one starts up.
Yes the animals do get sluggish, because there is an optimal temperature and
pathway, but cold-blooded animals can survive across a wide range of body
temperatures because of these multiple pathways.
Warm-blooded animals have lost this ability to use multiple pathways. Their
internal temperature must be exactly right, or they die.
