Quotes About Biology

What is true for E. coli is also true for the elephant.

Todo ser vivo es también un fósil. Lleva en sí, y hasta en la estructura microscópica de sus proteínas, las huellas, si no los estigmas, de su ascendencia. Esto es más cierto en el Hombre que en cualquier otra especie animal, en razón de la dualidad, física e «ideal», de la evolución de la que es heredero.

Wheat, soy, grains and beans contain anti-nutrients that are impossible for our bodies to digest.

REFERENCE RANGES FOR ALANINE AMINOTRANSFERASE (ALT) Category ALT Normal Range (IU/L) Men 0 to 55 Women 0 to 40

Biology taught me that a field undergoing development should be investigated always from the viewpoint of its past development. Who today would study anatomy without embryology? In exactly the same way epistemology without historical and comparative investigations is no more than an empty play on words or an epistemology of the imagination.

ALCOHOL HAS NO BIOLOGICAL CONNECTION TO ABUSE OR VIOLENCE Alcohol does not directly make people belligerent, aggressive, or violent. There is evidence that certain chemicals can cause violent behavior — anabolic steroids, for example, or crack cocaine — but alcohol is not among them. In the human body, alcohol is actually a depressant, a substance that rarely causes aggression. Marijuana similarly has no biological action connected to abusiveness.

Men and women have been hardwired with distinctive gender traits that, when working together, serve the human race and display the glory of God.

New mutations don't create new species; they create offspring that are impaired.

Although random mutations influenced the course of evolution, their influence was mainly by loss, alteration, and refinement... Never, however, did that one mutation make a wing, a fruit, a woody stem, or a claw appear. Mutations, in summary, tend to induce sickness, death, or deficiencies. No evidence in the vast literature of heredity changes shows unambiguous evidence that random mutation itself, even with geographical isolation of populations, leads to speciation.

Possibly here in the Holocene, or just before ten or twenty thousand years ago, life hit a peek of diversity. Then we appeared. We are the great meteorite.

For all the accomplishments of molecular biology, we still can't tell a live cat from a dead cat.

Los cuerpos grandes son una ventaja para los luchadores; los genitales grandes lo son para los amantes.

Sergestid shrimp, he suggests, acquired, integrated, and put to work at least four intact genomes. To Williamson the inheritance of these acquired genomes, not random mutations, determines the evolutionary success of these shrimp today.

All living things respond to the same 24-hour rhythm, in tandem with the Earth's rotation. Halberg coined the terms "chronobiology"—the influence of time and certain periodic cycles on biological function—and "circadian" (from Latin circa = about; and dies = day) for daily biological rhythms. He created the Chronobiology Laboratories at the University of Minnesota and became known

is not surprising that biological systems like human beings are sensitive to external signals, such as geomagnetic disturbances. Magnetic fields are caused by the flow of electrons and atoms with charge, known as ions, and whenever magnetic forces change, they alter the direction of the flow of these atoms and particles. Ultimately,

1940s by neuroanatomist Harold S. Burr from Yale University, who studied and measured electrical fields around living things, specifically salamanders. Burr discovered that salamanders possessed an energy field shaped like an adult salamander, and that this blueprint even existed in an unfertilized egg.13

And when he finally plotted it all up, there it was: the number of cell types in an organism did indeed scale roughly as the square root of the number of genes it had.

he had to find out what was important about self-reproduction, independent of the detailed biochemical machinery.

If the origin of life had really been a random event , then it had really been a miracle.

Charles called himself a Darwinist, and yet he had not really understood Darwin. But then, nor had Darwin himself.

action, and there are also structures so distinct from the rest of the cell 'jelly', like cells within cells, that the best explanation of their presence is that that is indeed what they are. These semi-autonomous 'cells within the cell' are called organelles. As we saw in Chapter Four, Lynn Margulis has explained how the ancestors of the organelles used to be separate, bacteria

Humans are mammals and their red blood cells are similar in that they do not have nuclei. Reptiles and birds have nucleated red blood cells, we do

The Winkles appeared to greet the morning vigorously. Although Homer had never heard human beings make love, or moose mate, he knew perfectly well that the Winkles were mating. If Dr. Larch had been present, he might have drawn new conclusions concerning the Winkles' inability to produce offspring. He would have concluded that the violent athleticism of their coupling simply destroyed, or scared to death, every available egg and sperm.
