Quotes About Biology

Today we have big, crude instruments guided by intelligent surgeons, and we have little, stupid molecules of drugs that get dumped into the body, diffuse around and interfere with things as best they can. At present, medicine is unable to heal anything.

That animal part of us, it's the most interesting part. It's everything that has to do with drives, with things we can't stop ourselves from doing, with all the spaces where we're unable to reason with ourselves. It has its dark side, but there's a luminous side, too, which is the fact that we're just another species of animal.

And, you know, the fact is, if you believe in evolution, we all have a common ancestor, and we all have a common ancestry with the plant in the lobby. This is what evolution tells us. And, it's true. It's kind of unbelievable.

Much as we might wish to believe otherwise, universal love and the welfare of the species as a whole are concepts which simply do not make evolutionary sense.

In examining disease, we gain wisdom about anatomy and physiology and biology. In examining the person with disease, we gain wisdom about life.

Thoughts are an important part of your inner wisdom and they are very powerful. A thought held long enough and repeated often enough becomes a belief. A belief then becomes your biology.

A lion is a mammal like us; an octopus is put together completely differently, with three hearts, a brain that wraps around its throat, and a covering of slime instead of hair. Even their blood is a different color from ours; it's blue, because copper, not iron, carries its oxygen.

There is another important difference as well. Human eyes have three visual pigments, allowing us to see color. Octopuses have only one—which would make these masters of camouflage, commanding a glittering rainbow of colors, technically color-blind. How, then, does the octopus decide what colors to turn? New evidence suggests cephalopods might be able to see with their skin.

Octopus slime is sort of a cross between drool and snot. But in a nice way. And it's very useful. It helps to be slippery if you're squeezing your body in and out of tight places. Slime keeps the octopus moist if it wants to emerge from the water, which some species of octopus do with surprisingly frequency in the wild.

astrophysicist Christopher McKay puts it: "The single non-negotiable thing life requires is water.

One kind of blue-green bacteria, Prochlorococcus, is so abundant—about 100 octillion (1 octillion = 1027) are alive at any given moment—that it alone is responsible for about 20 percent of the oxygen in the atmosphere. Put another way, this nearly invisible form of life generates the oxygen in one of every five breaths you take, no matter where on the planet you live.

Cia?a mamy zwierz?ce, lecz aspiracje boskie. Hormony przekroczy?y bariery postawione im przez biologi?, przez prawa ?wiata zwierz?t. Hormony nasze produkuj? enzymy g?odów nie do zaspokojenia, marze? nie do zrealizowania, t?sknot nie do zag?uszenia.

periods are the only thing i can think of where its a problem if you don't bleed

human red blood cells have no nuclei and thus possess no DNA of their own.

In Chapter 14, you can find out how the cell cycle is regulated and what happens when it goes awry.)

When a man and woman have sexual relations, who gets the most out of the deal? The man, or the woman? Since we live in a society full of tricks, the man thinks he gets more out of the encounter. But what do men really get out of it? The reality is that women have the potential to get more out of it than the man, especially if the man's seeds have accumulated a certain amount of value.

females were the source of the vital principle that gave the offspring life, while males provided the basic form. Because of this division, neither sex could reproduce by itself.

Nurse sharks have smoother skin than most sharks. It feels like sandpaper.

When you meet kin, there is an energy and sparkle between your bodies. It must be chemical somehow - DNA and genes.

We know that our cells are speaking to each other.

Nerve cells communicate with one another at specialized points called synapses. And these synapses are plastic - they can be modified by learning.

With the exception of certain rodents, no other vertebrate except Homo sapiens habitually destroys members of his own species.

A creationist can embarrass an evolutionist by asking for a definition of species.
