Here’s How Some Species Will Survive Climate Change

Every middle-school student learns the dogma: a species is defined as a group of organisms that interbreed and produce fertile young. When individual plants and animals can’t, we call them different species. Sometimes it’s a little confusing to imagine exactly how that might work between Great Danes and Chihuahuas, which are both Canis familiaris, but for the most part it’s a comforting way to make sense of the biological diversity around us. Except that it’s wrong.

Hybrids, or organisms that contain DNA from more than one species, were supposed to be the unlucky reproductive dead ends of parents from different species that lacked some Darwinian common sense; instead, new genomic data give us rampant evidence that species, even ones that aren’t very closely related, have been swapping genes in an act of evolutionary defiance that isn’t so vanishingly rare.

Typically, each species has to evolve its own beneficial genes, a laborious process of small mutations that can be hit or miss when it comes to conferring a benefit. This process takes many generations. But when different species hybridize, beneficial genes that have evolved in one species can, through mating with the hybrid, migrate to the other species in the blink of an evolutionary eye.

Rather than just tolerating such hybrid flexibility, evolution conceivably could be driving it; those species that are able to reap the benefits of hybridization and skip ahead in the race to adapt have a better chance at long-term survival, and they may cope better with the new environments and the intensifying instability they now face.

Are the fake ass climate hoax stretch stories considered science at this point?

Unscientific American you should be called

animal's can teach us many thing's but it is a bit unfair to call this hybridization when there is no evidence they use it at all

It's not GlobalWarming .... it's GlobalCycles .... it's Nature .... it's Not ManMade ..... Stop being Propaganda shills .... present some actual History & science for a change.

El_Gatito89 It's not global warming, as much as civilization growth into wild areas, and many of male species being killed on roads and highways.

Editorial: Deadly floods in Pakistan sound an alarm. Climate change is an urgent threat.From the Editorial Board: 'For developed nations to think they’re somehow immune, or that climate change remains a faraway threat, is foolhardy and patently dangerous.' Good to evolve to Green energy, but reality dictates in short term of human span not much will change climate wise for the better. So now we ought be thinking in ways to engineer living w/ impact on H2O needs, rising seas, strengthening infrastructure to survive w/o fossil fuel.
