Moreover, the concern of some that moving DNA among species would breach customary breeding barriers and have profound effects on natural evolutionary processes has substantially disappeared as the science revealed that such exchanges occur in nature.

The one process now going on that will take millions of years to correct is the loss of genetic and species diversity by the destruction of natural habitats. This is the folly our descendants are least likely to forgive us.

With the advent of genetic engineering the time required for the evolution of new species may literally collapse.

I did not claim that speciation occurs only in founder populations.

Exchange of breeding individuals between two populations tends to homogenize their gene pools.

The first and most important reason for its elimination is the unquestioned fact that evolution is not a science; it is a hypothesis only, a speculation.

Most evolving lineages, human or otherwise, when threatened with extinction, don't do anything special to avoid it.

Where we are going as a species is a big question. Human evolution certainly hasn't stopped. Every time individuals produce a new zygote, there's a reshuffling and recombination of genes. And we don't know where all of that is going to take us.

You can cut a tree down, and it grows back. Once a species goes, it's gone forever.

Gentility is what is left over from rich ancestors after the money is gone.
