Evolutionary plasticity can be purchased only at the ruthlessly dear price of continuously sacrificing some individuals to death from unfavourable mutations. Bemoaning this imperfection of nature has, however, no place in a scientific treatment of this subject.

The business of proving evolution has reached a stage when it is futile for biologists to work merely to discover more and more evidence of evolution. Those who choose to believe that God created every biological species separately in the state we observe them, but made them in a way calculated to lead us to the conclusion that they are the products of an evolutionary development are obviously not open to argument. All that can be said is that their belief is an implicit blasphemy, for it imputes to God an appalling deviousness.

Man is the only living being who has a developed self-awareness and death-awareness.

Does the evolutionary doctrine clash with religious faith? It does not. It is a blunder to mistake the Holy Scriptures for elementary textbooks of astronomy, geology, biology, and anthropology.

No known human group... simply throw out its dead without any ritual or ceremony. In stark contrast, no animal practices burial of dead individuals of its own species.

The living world is not a single array... connected by unbroken series of intergrades.

Nature's stern discipline enjoins mutual help at least as often as warfare. The fittest may also be the gentlest.
