A small fish crawling on stumpy limbs from a shrinking desert pond is an icon of can-do spirit, emblematic of a leading theory for the evolutionary transition between fish and amphibians. This theorized image of such a drastic adaptation to changing environmental conditions, however, may, itself, be evolving into a new picture.

Fossils Cast Doubt on Climate-change Projections on Habitats
EUGENE, Ore. -- Nov. 18, 2014 -- Leave it to long-dead short-tailed shrew and flying squirrels to outfox climate-modelers trying to predict future habitats. Evidence from the fossil record shows that gluttonous insect-eating shrew didn't live where a species distribution technique drawn by biologists put it 20,000 years ago to survive the reach of glaciers, says University of Oregon geologist Edward B. Davis. The shrew is not alone.
