genetics

At bottom every man knows well enough that he is a unique being, only once on this earth; and by no extraordinary chance will such a marvelously picturesque piece of diversity in unity as he is, ever be put together a second time.

A four-letter alphabet called DNA.

The human has genetic adaptation to natural electromagnetic radiation. Increasing, reducing or removing the natural radiation exposures results in a sickened human that may progress onto a diseased state.

Some say we are not like humans but we are more like them than we are different. Man and animals are in the same species as mammals as they have mammary glands that produce the milk to nurse their young. Their lungs breathe air and their blood is warm. They are vertebrates in that their skeletal system and well-designed spines hold their bodies together. Each cell is made of molecules, each molecule is made of atoms, and each atom is made of protons, neutrons and mostly electrons, which are made of waves of fibered light.

In microbiology the roles of mutation and selection in evolution are coming to be better understood through the use of bacterial cultures of mutant strains.

The more you treat your body and the cells as intelligent being the more you will be sharp, quick, competent, and fulfilled.

If there's any interaction between genes and languages, it is often languages that influence genes, since linguistic differences between populations lessen the chance of genetic exchange between them.
