If other species are so successful at evolving so quickly to adapt to global warming, we (homo sapiens) are going to be soon left out in the cold, so to speak.

Well there's the beginnings of a science fiction movie! ;)Of course, we do still own the ability to start a fire and shoot a gun, so I guess we win after all! LOL!!

The problem is that most quick adaptation is through the selection of an existing allele(s). If the species has no allele that confers necessary adaptations it is less likely to survive. The survivability of a species is heavily dependent on the speed of the environmental changes; the changes we see occurring in present ecosystems are too fast and furious for many species to survive.

Diversity will drop dramatically before vacant niches encourage a rebound diversity increase. What will that cost us? - How will that affect our survivability. - What are the ethical costs?
