SAMUEL JACKSON HOLMES
He was restating the argument of the Eugenics Movement but was a critic of many parts of it. This Movement, which grew quite popular for a while, tried to improve the race of man, not by improving individual people or even a generation of people, but of selective and restrictive breeding of humans. The coercion and bias associated with it caused one of the worst violations of human rights in American History, and then was picked up by Adolf Hitler who carried the ideas to one of the worst atrocities in human history.
Actually, while such selective breeding is possible in all animals, the selection for a single trait almost always produces other unintended and unanticipated traits and these could be devastating to the “new generation”, unpleasant, benign, or anything else. At the time selective breeding was the only possible tool to produce “desirable” traits in an animal or to eliminate what someone things of as “undesirable” traits. Today, our understanding of the human genome and genetic engineering offers a much more reliable possibility of affecting animal traits without as many risks of random and unintended consequences that are present with breeding.
Samuel Jackson Holmes was an American zoologist and eugenicist. He was a professor at the University of California, Berkeley (UC-Berkeley) for 27 years. Noted as a genetics pioneer, and for his studies of animal behavior, heredity, and evolution. Over the course of his career he migrated from studying animals to humans, taking the behaviors and traits learned in the former and looking for them in the later.
