That will ensure more reproductive success in the long run.
Sometime or other, almost all of us secretly worry that were just impostorsbumbling children masquerading as competent adults.
Is this related to our equally distinctive large brains and high intelligence?
Cabbage white butterflies, the nemesis of the veggie gardener, flit from kale to cabbage to chard, in search of the best host for their eggs after they hatch and larvae start munching. Snell-Rood found that all the bugs start out with a strong innate bias toward green plants such as kale.
But some adventurous and intelligent butterflies may accidentally land on a nutritious red cabbage and learn that the red leaves are good hosts, too.
The experimenters presented cabbage whites with a choice between leaves that had been grown with more or less fertilizer, and leaves that either did or did not have a dead, carefully posed cabbage white pinned to them. But some preferred the leaves that were especially nutritious.
Whats more, these same butterflies avoided leaves that were occupied by other butterflies, where the eggs would face more competition.
