As in all of biology, comparative studies showing differences among species are often helpful for a better understanding of the basic mechanisms; with all its advantages, there is a danger of clinging exclusively to one model organism.

Any object, whether animate or inanimate, will have a size. Airplanes, boats, or musical string instruments vary in size just like animals and plants, and in all cases, their size and their material construction are totally different matters even though they affect one another.

That the role of size has been to some degree neglected in biology may lie in its simplicity. Size may be a property that affects all of life, but it seems pallid compared to the matter which makes up life. Yet size is an aspect of the living that plays a remarkable, overreaching role that affects life's matter in all its aspects.

It is hard to explain the huge variety of diatoms - a microorganism that has 100,000 species - in terms of natural selection.

My dad was a composer and a musician, but he never finished high school. His formal education was rather minimal from the standards of today's college graduates and Ph.D.'s, but he had a deep interest in questions of science and questions of the universe.

If pro-abortionists want to commit intellectual suicide and deny scientific facts, that's their problem. But there's no reason a civilized society should fund their anti-scientific outlook - or accept its inhumane consequences.

Often, some people dress something up to make it sound scientific, use scientific words, call themselves doctor something-or-other, and then you look them up, and they're trying to make it sound like something it's not. There's this entire field that's adding the word 'quantum' to everything. It doesn't even make sense in that context.

Creativity is essential to particle physics, cosmology, and to mathematics, and to other fields of science, just as it is to its more widely acknowledged beneficiaries - the arts and humanities.
