Many differences are rooted in biology and reinforced through culture so it's important to acknowledge that. Because if you say men and women are the same and if male behaviour is the norm and women are always expected to act like men we will never be as good at being men as men are.

It has become part of the accepted wisdom to say that the twentieth century was the century of physics and the twenty-first century will be the century of biology.

But while doing that I'd been following a variety of fields in science and technology including the work in molecular biology genetic engineering and so forth.

One of my degrees was a science degree in biology.

But honestly if you do a rigorous survey of my work I'll bet you'll find that biology is a theme far more often than physical science.

For me science is already fantastical enough. Unlocking the secrets of nature with fundamental physics or cosmology or astrobiology leads you into a wonderland compared with which beliefs in things like alien abductions pale into insignificance.

A permanent base on Mars would have a number of advantages beyond being a bonanza for planetary science and geology. If as some evidence suggests exotic micro-organisms have arisen independently of terrestrial life studying them could revolutionise biology medicine and biotechnology.

Evolution is the fundamental idea in all of life science - in all of biology.

Biology meaning the science of all life is a late notion.

Biology is the science. Evolution is the concept that makes biology unique.
