Why female moths are big and beautiful
Tags: university of arizona[Source: ScienceDaily] - In most animal species, males and females show obvious differences in body size. But how can this be, given that both sexes share the same genes governing their growth? University of Arizona entomologists studied this conundrum in moths and found clues that had been overlooked by previous efforts to explain this mystery of nature.
Take a look around in the animal world and you will find that, in most organisms, individuals of one sex are larger than the other of the species.
Even though evolutionary biologists have long recognized this discrepancy, called sexual dimorphism, they have struggled for decades to solve a major paradox: How can males and females of one species be of different sizes, given that they share the same genetic blueprints dictating their development and growth?
