Quotes About Biology

It is a well-documented fact that guys will not ask for directions. This is a biological thing. This is why it takes several million sperm cells... to locate a female egg, despite the fact that the egg is, relative to them, the size of Wisconsin.

One of the first papers I wrote at the University of Wisconsin, in 1977, was on stem cells. I realized that if I changed the environment that these cells were in, I could turn the cells into bone, and if I changed the environment a bit more, they would form fat cells.

With my biology degree, I got this job at an environmental lab. We tested sewage runoff, we tested chemical warfare waste runoff. It's a job I'll never do again and I would never wish upon anybody.

As Darwin himself was at pains to point out, natural selection is all about differential survival within species, not between them.

Women of child-bearing age steadily run out of eggs by the continuous process of cell death. While reading a copy of the 'Guardian' carefully from cover to cover, a normal woman will have lost on average two eggs - while, typically, a normal man will have made 70,000 new sperm.

One-third of all female infertility is the result of blocked fallopian tubes. If fertilization could be done in the lab and then the fertilized egg implanted in the womb, it would get around that problem. Millions of women who cannot have children would suddenly be able to.

The minute those two little particles inside a woman's womb have joined together, billions of decisions have been made. A thing like that has to come from entropy.

Men are different than women, and men live with - with some very difficult obstacles. I mean, a man, basically, in his true nature, is to spread his seed, and a woman is a gatherer, and that's kind of the way we're - our limbic system is set up, you know.

Obviously, the genes of women are flawed. They are poorly designed creatures who do not want to have sex nearly as often as needed for the human race to get along peaceably and fruitfully.

Influenced by him, and probably even more so by my brother Theodore (a year older than me), I soon became interested in biology and developed a respect for the importance of science and the scientific method.

If Darwin's theories are true, then we have within us the physical memory of when we were fish or apes.

The theory of evolution, like the theory of gravity, is a scientific fact.

Extreme heroism springs from something that no scientific theory can fully explain; it's an illogical impulse that flies in the face of biology, psychology, actuarial statistics, and basic common sense.

Some people would claim that things like love, joy and beauty belong to a different category from science and can't be described in scientific terms, but I think they can now be explained by the theory of evolution.

Game theory is a branch of, originally, applied mathematics, used mostly in economics and political science, a little bit in biology, that gives us a mathematical taxonomy of social life, and it predicts what people are likely to do and believe others will do in cases where everyone's actions affect everyone else.

Essential to the theory of evolution is the premise that everything has come into being by itself.

We humans have a tendency to see ourselves as completely different from other animals, and the way in which large segments of the public continue to reject the theory of evolution is just one symptom of that malaise.

Evolution is a theory, and it's a theory that you can test. We've tested evolution in many ways. You can't present good evidence that says evolution is not a fact.

What Darwinian theory shows us is that all human races are extremely close to each other. None of them is in any sense ancestral to any other; none of them is more primitive than any other. We are all modern races of exactly equal status, evolutionarily speaking.

Many scholars working in the humanities have already shown interest in brain research. For years, contemporary theory in the humanities has left the body and biology out of their discussions.

The evolutionary theory of senescence can be stated as follows: while bodies are not designed to fail, neither are they designed for extended operation.

Practically all animals which move fast in a homogeneous medium have found means of giving their body a streamlined shape, thereby reducing friction to a minimum.

Proteins are constantly being degraded. Therefore, simultaneous production of proteins is required.

The way life manages information involves a logical structure that differs fundamentally from mere complex chemistry. Therefore chemistry alone will not explain life's origin, any more than a study of silicon, copper and plastic will explain how a computer can execute a program.
