Scientists Breed Big-Brained Guppies To Demonstrate Evolution's Trade-Offs 121
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 (abstract). But the bigger-brained fish also tended to have smaller guts and produce fewer babies."
