According to the film, and based on your understanding of natural selection from class readings, lecture, and discussion, people in the town of Eyam who were resistant to the Bubonic Plague developed that genetic resistance in response to the plague.'

According to the film, and based on my understanding of natural selection from class readings, lecture, and discussion, I believe;

Several teams of scientists round the world have, for a while, been analyzing the opportunity that a genetic mutation perpetuated via the organism responsible for bubonic plague, or the Black Death, inside the Middle Ages - Yersinia pestis - would possibly provide humans now sporting the mutation extended resistance to the Human Immunodeficiency Virus (HIV) compared to non-companies. New studies has thrown doubt on the micro-organism that become concept to have precipitated the Black Death, but the link to HIV resistance seems to remain.

In a observe published in the American Journal of Human Genetics (Am J Hum Genet 1998, 62:1507-1515) Stephen O'Brien and colleagues at the US National Cancer Institute, used coalescence principle to interpret current haplotype genealogy. They found that a genetic mutation that gives its providers safety towards the HIV virus became extraordinarily not unusual amongst white Europeans approximately seven-hundred years in the past - the equal length that the Black Death swept into Europe. The group also concluded that the geographic cline of the mutation frequencies and its latest emergence had been regular with a strongly selective historical event (which includes a virulent disease of a pathogen), driving its frequency upwards in populations whose ancestors survived the Black Death.
