The most consequential change in man's view of the world, of living nature and of himself came with the introduction, over a period of some 100 years beginning only in the 18th century, of the idea of change itself, of change over periods of time: in a word, of evolution.

Evolution ... is opportunistic, hence unpredictable.

A species is a reproductive community of populations reproductively isolated from others that occupies a specific niche in nature.

It seems to me that for Darwin the pulsing of evolutionary rates was a strictly vertical phenomenon.

I have the honesty to say I'm an Atheist. There is nothing that supports the idea of a personal God.

I feel that one species, mankind, doesn't have the right to exterminate

A species consists of a group of populations which replace each other geographically or ecologically and of which the neighboring ones integrate or hybridise wherever they are in contact or which are potentially capable of doing so (with one or more of the populations) in those cases where contact is prevented by geographical or ecological barriers.
