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.
“We usually think of natural selection as acting slowly, over hundreds or thousands of years,%26quot; said study team member Gregory Hurst, an evolutionary geneticist at the University College London. %26quot;But the example in this study happened in a blink of the eye, in terms of evolutionary time.%26quot;

Yes, they can. Even without the involvement of a government, socialistic or other. Yours is a good example of that. However, the factors present that have caused the decline likely needs to be removed. The involvement of a government tends to ensure that.

animals can survive without us .. but it cant survive without plants as you and all know that we cut trees and plants for so many things . so the plants die out and so does the animals . so if we live in a planet and the animals live in another the animals would be the happiest things in the universe

Of course they can.The worst enemy of any endangered species is man.The species is either hunted to extinction, or the climate changed so the species can%26#039;t survive.But funnily enough the lowest form of life, will probably end up being the only form of life that survives.
