How powerful is your evolutionary, algorithm?

Cryptic cuckoo eggs hide from competing cuckoos.

Interspecific arms races between cuckoos and their hosts have produced remarkable examples of mimicry, with parasite eggs evolving to match host egg appearance and so evade removal by hosts. Certain bronze-cuckoo species, however, lay eggs that are cryptic rather than mimetic. These eggs are coated in a low luminance pigment that camouflages them within the dark interiors of hosts' nests. We in...

Knowing How vs . Knowing That
