Quotes About Biology

Violet es oxígeno, carbono, hidrógeno, nitrógeno, calcio y fósforo. Los seis elementos de los que todos estamos compuestos, aunque no puedo evitar pensar que es algo más que eso, que posee otros elementos de los que nadie ha oído hablar y que la diferencian de todos los demás.

Male fruit flies also become a bit randy, although they are less likely to mate successfully—perhaps because, in their alcohol-induced haze, they frequently court other males by mistake, instead of females.

Worms appeared on Earth more than six hundred million years ago. They were soft, small-bodied creatures that fed on nutrients at the bottom of the sea. But they were different from anything that had come before because they had heads with mouths and primitive brains. Also new were there guts and organs, arteries and veins. Today there are so many worms in the world that even if every other substance were to disappear from Earth the shape of our planet would still be outlined by them.

The third explanation for 1918's lethality is that the flu virus triggered an overreactive immune response that turned the body against itself.

Life itself: Its origin and nature.

We were making the first step out of the age of chemistry and physics, and into the age of biology.

Enzymes are things invented by biologists that explain things which otherwise require harder thinking.

Notice, there is a fundamental difference between providing a biological explanation of why we are inclined to accept a given moral principle and showing that we should accept it. If the ultimate explanation is biological, it is far from obvious that such principles truly obligate us to follow them.

DNA wasn't a simple recipe book that could be readily understood.

That the human body or any other animal is a system comprised of millions of smaller systems, some of them completely separate from us genetically, shouldn't be an earthshaking revelation.

There are even genes that correlate with charisma. Some of them overcompensate for a lack of internal empathy. They make you feel like they care more than anyone else while you're nothing to them.

Although my specialty is computational biology, I know enough human anatomy to suspect that the bone Eddie is chewing on isn't from something that was on a kitchen table or wandered into the backyard after getting hit by a car.

I think it is always appropriate to end a conversation about sperm with a sweaty handshake.

It is not at all coincidental that Darwinian psychology has the same difficulty explaining the unity and integration of human reasoning as Darwinian biology has explaining the unity and integration of irreducibly complex functions. Practical and theoretical reasoning is often irreducibly complex. A given argument has several well-matched, interacting reasons, and the removal of any one of them makes the argument break down.
