Evolution Occurs in the Blink of an Eye
A population of butterflies has evolved in a flash on a South Pacific island to fend off a deadly parasite.
The proportion of male Blue Moon butterflies dropped to a precarious 1 percent as the parasite targeted males. Then, within the span of a mere 10 generations, the males evolved an immunity that allowed their population share to soar to nearly 40 percent—all in less than a year.
So, if we stop treating cancer, aids and other diseases, we would evolve an immunity to them and we wouldn't have to worry about them. Problem solved! Yea!
