Answer:
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 <u>American Journal of Human Genetics (Am J Hum Genet 1998, 62:1507-1515) Stephen O'Brien and colleagues at the US National Cancer Institute</u>, 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.
Answer: Not really sure what the question is but I found this.
Explanation:
The Stevenson family’s involvement in lighthouse engineering began with RLS’s grandfather, Robert Stevenson (1772-1850).
Robert’s mother Jean Lillie (1751-1820) had married Thomas Smith (1753-1815) who was an engineer at the Northern Lighthouse Board.
The most courageous character in To Kill a Mockingbird to me is Jem. He was always the one that would take the dares to touch the Radley house, he was courageous enough to GO BACK to get his pants from the fence. When they were being chased by Bob Ewell, instead of booking it, he told Scout to run as he tried to handle Bob, A GROWN MAN.
