without a doubt, that we evolved from apes." Langdon nodded. "I'm

We are social animals and any honest assessment of how sex actually functions in our lives would lead us to conclude that while its original purpose was purely reproductive, we long ago—eons ago—repurposed it in ways that conferred evolutionary advantages that weren't solely about passing on our genes. You were likelier to survive and your offspring were likelier to survive if you were liked, and you were likelier to be liked if you gave good head.

Among the main biological changes in happiness is an increased activity in a brain center that inhibits negative feelings and fosters an increase in available energy, and a quieting of those that generate worrisome thought.

A mais antiga raiz de nossa vida emocional está no sentido do olfato, ou, mais precisamente, no lobo olfativo, células que absorvem e analisam o cheiro.

The slow, deliberate forces of evolution that have shaped our emotions have done their work over the course of a million years; the last 10,000 years, despite having witnessed the rapid rise of human civilization and the explosion of the human population from five million to five billion, have left little imprint on our biological templates for emotional life.

non-twin children who are adopted into different families resemble their biological siblings in personality, even though they may rarely or never have met them, and they have no greater resemblance in personality to their adoptive siblings, who they grew up with, than they do to randomly chosen strangers. The correlation is essentially zero.

"Every single cell in the human body replaces itself over a period of seven years. That means there's not even the smallest part of you now that was part of you seven years ago."

The brain is a complex biological organ of great computational capability that constructs our sensory experiences, regulates our thoughts and emotions, and control our actions.

You can free yourself from aging by reinterpreting your body and by grasping the link between belief and biology.

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

The young blush much more freely than the old but not during infancy, which is remarkable, as we know that infants at a very early age redden from passion.

People tend to shrink with age, especially after age 50 or so. It has to do with spaces between the joints amount of cartilage and posture. Bone length does not change.

The females hear the call. The male hugs his mate. He fertilizes her eggs as she lays them in the water.

Tears are scientifically described as a Secretion. I can understand that a secretion may be healthy or unhealthy, but I cannot see the interest of a secretion from a sentimental point of view.

The second biological lesson of history is that life is selection. In the competition for food or mates or power some organisms succeed and some fail. In the struggle for existence some individuals are better equipped than others to meet the tests of survival.

The third biological lesson of history is that life must breed. Nature has no use for organisms, variations, or groups that cannot reproduce abundantly.

So the first biological lesson of history is that life is competition.

Utopias of equality are biologically doomed[.]

Darwin furthered the transformation. As the astronomer had lost the Earth in space, the biologist lost man in the infinity of time, in the long procession of transitory species that had walked the earth or swum the sea or flown the air; man became a mere line in Nature's interminable odyssey. But it was Darwin, too, who opened a way to what John Morley called "the next great task of science—to create a new religion for humanity.

He is both heir and prototype simultaneously of all the geography and climate and biology which sired old Carothers and all the rest of us and our kind, myriad, countless, faceless, even nameless now except himself who fathered himself, intact and complete, contemptuous, as old Carothers must have been, of all blood black white yellow or red, including his own.

The big news in biology this week was the announcement that we've stopped evolving, in the biological sense. I'll buy that. Technology has stopped us, and technology will take us on, into a new evolution, one Mr. Bush never dreamed of, and neither, I'm sure, have I.

Rather than plug a piece of hardware into our gray matter, how much more elegant to extract some brain cells, plop them into a Petri dish, and graft on various sorts of gelatinous computing goo. Slug it all back into the skull and watch it run on blood sugar, the way a human brain's supposed to. Get all the functions and features you want, without that clunky-junky twentieth-century hardware thing.
