She was suspected of having hereditary mental illness and, in the s, in order to cleanse the population of her genes, was confined to a place called the Virginia State Colony. One of the superintendents of the colony was a man named Albert Priddy, who was one of the great proponents of eugenics through selective sterilization.

We now know that the chances of Carrie Buck having the kind of hereditary mental illness Priddy was trying to eradicate by sterilization were actually pretty slim. In the s to '40s, the Nazi Party launches the racial hygiene movement to try and ensure they cleanse the human race of genetic infirmaries.

They try to identify anyone who has a suspected hereditary infirmity: the deaf, the blind, or those with congenital illnesses of various sorts. This forms the training ground for the much wider extermination program of the Holocaust.

By the s, Jewish men and women are already disproportionately being targeted as part of this racial hygiene movement. In the s and s, people had thought about what was carrying the code to build organisms and to repair and maintain organisms. Thomas Morgan, the great fruit fly biologist , had, along with others, understood that genetic information was carried in chromosomes.

So the hunt was to try to find the chemical that carried this information. If you could identify that chemical and manipulate or move it from one organism to another organism, you could potentially change biological, hereditary information. The discovery that it was DNA that carried genetic information was an enormous surprise. It was done by Oswald Avery and his colleagues at Rockefeller University in the s.

Then the race began to try to solve the structure. How on Earth could DNA carry information to build you and me? That was solved by discovering the structure of DNA. Four letters carrying the information that allows humans to be built.

And this ultimately led to the Human Genome Project. Mitochondrial Eve is a fascinating concept. The idea is that the genetic information we inherit comes from our fathers and mothers, one chromosome from each. But that genetic information comes exclusively from your mother. If you look at that mitochondrial information, yours came from your mother, hers came from her mother, and so forth.

There is a matrilineal lineage. Humans, as a species, are quite young, only about , years old. If you wish to unsubscribe, you can update your preferences at any point. While obtaining degrees in biology from the University of Alberta and biochemistry from Penn State College of Medicine, I worked as a freelance science and medical writer.

I was able to hone my skills in research, presentation and scientific writing by assembling grants and journal articles, speaking at international conferences, and consulting on topics ranging from medical education to comic book science.
