Big brains are pricey, guppy study shows
Date:1/3/2013

ained guppies outscored their smaller-brained peers in a test of numerical learning. With more energy devoted to brain-building, brainy fishmales especiallydid have smaller guts. They also left fewer offspring to the next generation.

Those effects were observed despite the fact that the fish were supplied with an abundance of food. The researchers say they are curious to see what will happen in future experiments with fish in a more competitive, semi-natural environment including limited resources and predators.

The findings lead Kolm and his colleagues to suggest that the relatively small family sizes of humans and other primates, not to mention dolphins and whales, might have helped to make our big brains possible.
