Submission + - Scientists breed big-brained guppies to demonstrate evolution's trade-offs (nbcnews.com)

An anonymous reader writes: Scientists have long suspected that big brains come with an evolutionary price — but now they've published the first experimental evidence to support that suspicion, based on their efforts to breed big-brained fish.
A Swedish team found it relatively easy to select and interbreed common guppies to produce bigger (or smaller) brains — as much as 9.3 percent bigger, to be precise. But the bigger-brained fish also tended to have smaller guts and produce fewer babies.
