Once again, social meanings are enmeshed within beliefs about heredity.

Genes are the basic units of heredity in living organisms.

Folk ideas about heredity are a particularly powerful cultural tool, but they are not unique to pre modern societies.

The distinction is similar to that proposed by August Weismann, who distinguished between germ plasm (heredity) and somatic cells (the body).

The tremendous success of experimental approaches to development, heredity, and metabolism in the 1900s and 1910s demonstrated the power of experimentation in biology.

Harkening back to Susan Blackmore's talk, we now have a means of transmitting information with heredity and selection, and we know where that leads.

Widely publicized in recent years by Oxford evolutionary biologist Richard Dawkins, the new synthesis unites Darwin s theory of natural selection with Mendelian genetics, which explains heredity.

The concept of natural selection was originally developed in the absence of a valid theory of heredity at the time of Darwin's writing, nothing was known of modern genetics.

But like any other peoples, our own application of that information to the puzzle of our existence is strongly influenced by our non scientific ideas, our pervasive folk ideologies of heredity.

Even contemporary science has its own cultural ideologies about heredity, which are often difficult to disentangle from the complex data and high technology that we believe produces objective, value free glimpses of nature.

For a long time, those who studied the nature of life and heredity were divided into two camps epigeneticists , who emphasized environmental influences on living organisms, and preformists , who stressed the similarities between parents and progeny.

Thomas Hunt Morgan (September 25, 1866 December 4, 1945) was an American evolutionary biologist, geneticist and embryologist and science author who won the Nobel Prize in Physiology or Medicine in 1933 for discoveries elucidating the role that the chromosome plays in heredity.
