The Dalai Lama on "Natural Selection"

The following is a quote from: The Universe in a Single Atom by the Dalai Lama page 100 and 101:

"Natural selection can be seen as explaining which kinds of flies or monkeys can best survive in their chosen environments,  and how beings like modern humans evolved from apelike ancestors. Despite their obvious differences, humans and chimpanzees share 98 percent of their dna: a difference of only 2 percent accounts for the distinction between the two species(the difference between humans and gorillas is 3 percent).  Likewise, on the genetic level, natural selection seems to explain how mutations in genes, which are random but arise naturally, can be selected out and hence create new varieties within living beings. Genetic mutation is also thought to be the engine for evolution at the molecular level. And natural selection is seen as the mechanism that favors the development of neural groups (transmitters, receptors, and so forth),  which give rise to the individuality and variability of each brain and, on the level of the species, to the special qualities of human consciousness, for example." end quote from pages 100 and 101.

What I'm wondering is what changes the magnetosphere degrading will have on all life on earth that has dna, in humans, plants and animals.

If you study past, ecosystems here on earth like the dinosaurs age, for example, when it got to be 76 degrees Fahrenheit at the north pole then, it took ferns (that are very good at converting CO2 to oxygen) 1 million years from the north pole to the equator to convert the CO2 back to an environment more similar to the one of the 20th Century.

However, now we are moving back to 76 degrees Fahrenheit average temperature at the north pole once again. This will greatly change what humans and what animals and what plants will survive and which ones through mutation continue and change the world we live in ongoing.
