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

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.

I am a creationist and an evolutionist. Evolution is God's, or Nature's method of creation. Creation is not an event that happened in 4004 BC; it is a process that began some 10 billion years ago and is still under way.

Evolution as a process that has always gone on in the history of the earth can only be doubted by those who are ignorant of the evidence or are resistant to evidence, owing to emotional blocks or plain bigotry.

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

Seen in the light of evolution, biology is, perhaps, intellectually the most satisfying and inspiring science. Without that light it becomes a pile of sundry facts -- some of them interesting or curious but making no meaningful picture as a whole.

Nothing in biology makes sense except in the light of evolution.
