Quotes About Biology

If you stop and think through what it means to grow, the process is astonishing. Each part of the body has to change its shape and size to match every other part. There's no central blueprint for the construction of an adult human. Each cell has to decide for itself, using nothing more than chemical signals and its own network of genes, RNA molecules, and proteins.

The concept of genes driving people's appetite caused them to lose some control of their own.

That's not because HPV was rare—far from it: a 2014 study on 103 healthy people detected the viruses in 71 of them—about 69 percent.

Stwierdzili, ?e komórki synów znajdowaÅ'y siÄ™ w mózgach matek, gdzie rozrosÅ'y siÄ™ i produkowaÅ'y neuroprzeka?niki. Ich synowie pomogli im ksztaÅ'towa? myÅ›li.

If I could compare cells from my left and right hands, they would not be genetically identical, but they would be vastly more similar to each other than to any cell from my brother, Ben.

Trudno wyobrazi? sobie, ?e rak ma cokolwiek wspólnego z ró?owym grapefruitem. A jednak oba sÄ… produktami mozaicyzmu: ?ywych linii komórkowych ró?niÄ…cych siÄ™ od reszty ciaÅ'a mutacjami, które odziedziczyÅ'y po komórkach macierzystych.

And they certainly would not have guessed that the human genome is partly composed from thousands of viruses that infected our distant ancestors, or that life as we know it may have gotten its start four billion years ago from viruses.

Po naszej Å›mierci – pisaÅ' Dawkins – pozostajÄ… po nas dwie rzeczy: geny i memy

When a cell divides, it needs another army of molecules to make a second copy of its DNA.

Like the good ape he is, man is a social animal, characterized by cronyism, nepotism, corruption, and gossip. That's the intrinsic blueprint for our 'ethical behavior,' he argued. It's pure biology.

El hombre, como buen simio, es animal social y en él priva el amiguismo, el nepotismo, el chanchullo y el comadreo como pauta intrínseca de conducta ética —argumentaba—. Es pura biología.

All interpretation or observation of reality is necessarily fiction. In this case, the problem is that man is a moral animal abandoned in an amoral universe and condemned to a finite existence with no other purpose than to perpetuate the natural cycle of the species. It is impossible to survive in a prolonged state of reality, at least for a human being. We spend a good part of our lives dreaming, especially when we're awake. As I said, pure biology.

O homem, como bom símio, é um animal social e imperam nele o amiguismo, o nepotismo, a trapaça e a mexeriquice comonorma intrínseca de conduta ética. É pura biologia.

Like the good ape he is, man is a social animal, characterized by cronyism, nepotism, corruption, and gossip. That's the intrinsic blueprint for our 'ethical behavior,'" he argued. "It's pure biology.

This phenomenon, which biology shows us is common to any social group, soon transforms the doctrine into a means of achieving control and political power. Divisions, wars and break-ups become inevitable. Sooner or later, the word becomes flesh and the flesh bleeds.

existence that we cannot explain by any other means, be it the moral void we perceive in the universe, the certainty of death, the mystery of the origin of things, the meaning of our lives, or the absence of meaning. These are basic and extremely simple aspects of existence, but our limitations prevent us from responding in an unequivocal way and for that reason we generate an emotional response, as a defense mechanism. It's pure biology.

hippocampus (Greek for "sea horse," which it resembles)

Le tournant fut annoncé en 1931 par un ouvrage de Julian Huxley, zoologue à l'université de Londres (et frère du romancier Aldous Huxley). Il y rejette, précisément au nom de la génétique, la notion de race, « terme de pure convenance pour aider à appréhender la diversité humaine10 ».

This is not to say that there is a clear line of demarcation between the living and the non-living. For the ancients, mould and mildew were not clearly differentiated from rust; from our perspective, prions and viruses are also indeterminate. They can reproduce their kind and they employ resources from their hosts to do so, but they do not have life cycles as plants and animals do.

I have always been fascinated by the story of Henrietta Lacks.

I've come to learn that there is a real difference between men and women. It's genetic.
