Quotes About Biology

Until the Cognitive Revolution, the doings of all human species belonged to the realm of biology, or, if you so prefer, prehistory

from a purely scientific viewpoint, human life has absolutely no meaning. Humans are the outcome of blind evolutionary processes that operate without goal or purpose.

En Homo sapiens, el cerebro supone el 2-3 por ciento del peso corporal total, pero consume el 25 por ciento de la energía corporal cuando el cuerpo está en reposo.

Is the division into men and women a product of the imagination, like the caste system in India and the racial system in America, or is it a natural division with deep biological roots? And if it is indeed a natural division, are there also biological explanations for the preference given to men over women?

Life" is defined as the ability to absorb nutrients (of any kind) and to replicate, not just to exist.

Human dynamism cannot be manipulated or switched on like that of a machine. It cannot be engineered or programmed. Human beings are created, not constructed – that is why they love to create their own reality. Human action cannot be explained by the laws of thermodynamics or by that of molecular biology.

An individual who has inhabited the social roles of both and and woman, with all the cultural baggage that accrues to both states - or to neither- acquires a kind of gender gnosis: a secret knowledge denied the rest of us who live in our assigned boxes, M or F, with really probing the boundaries.

The common embryological origin of the endothelium and blood cells perhaps explains why many cytokines that control hematopoiesis are released by the vascular endothelium.

Our biological rhythms are the symphony of the cosmos, music embedded deep within us to which we dance, even when we can't name the tune.

In God's eyes, walking on water is no more miraculous than the ability of hemoglobin to bond with oxygen inside a red blood corpuscle.

DNA is a perfect example of pure potentiality; in fact, it is the material expression of pure potentiality. The same DNA existing in every cell expresses itself in different ways in order to fulfill the unique requirements of that particular cell.

Selfishness is not an option, even when it comes to a cell's own survival.
