Evolution by natural selection isa process first described by two scientists, Charles Darwin and his contemporary Alfred Russel Wallace. Natural selection is theprocess by which organisms that are better adapted to their environment tend to survive and reproduce more offspring thathave similar traits. Over time, natural selection can lead to changes in populations. All the diversity on earth that we can seetoday is ultimately due to populations changing over time due to natural selection.In the pocket mice, we saw that the mice population had natural variation in their fur color. These variations arise frommutations (changes in DNA sequences) in sex cells (eggs and sperm). These variations are found in some individuals, and notothers, because of sexual reproduction. In other words, sexual reproduction generates eggs and sperm that contain a variety ofpossible traits. Humans, as a population, also have variations. Look around at your classmates. Some variations we can easilysee, hair color is an example. However, many of the differences between people are traits that we cannot see. For example,some people make an enzyme, lactase, as an adult. These people are able to easily digest lactose, the sugar found in milk.Other people do not produce this variation; they are lactose-intolerant and cannot easily digest milk. Another example is bloodtype. Humans have different blood types, but this trait is not visible just by looking at someone.Scientists have been studying variations in the immune systems of different populations of people in order to try to determine itsrole in survival during the Black Plague . Geneticists have found that there are differences in immune system genes (section ofDNA that determine a trait) between populations of people whose ancestors were exposed to the Black Death in Europe, andthose that were not exposed (such as people from China and Africa). Many of the surviving people from Europe do have a setof genes that provide partial to full immunity to Yersinia pestis, the bacteria that caused the Black Plague.JAN 92784...lil ChromeFileEditViewHistory BookmarksРеopleTabWindowHelp88%Wed Jan 27 1:45 PMEvolution XE TENZINE XParaphra x b Search re xClasswor XMeet(MP2) Wi XDeltaMat X New Tab+docs.google.com/document/d/1wlo4ee5fHQWkey0h-B8FYluBGBAx98BFQ8RDOkPiaX0/editB I U A90%Normal textCentury Go..12+...Or geneS IMUT PIOVIUE Pa TIUITO TUIL I||I|||O||y TO TEISIL INU PESTIS, ITTE DUCIENA INUI CAUSEU INE DIUCKFIaguE.People whose ancestors are from China and Africa generally lack these genes. Therefore, there may have been some peopleliving in Europe during the Black Death that were lucky enough to have variations in their immune systems that gave them someimmunity to the Black Plague. These people were possibly better able to fight off the bacteria, survive, reproduce, and passthese immune system traits on their offspring.Variation in the human immune system may also explain why some people are more susceptible to severe COVID-19 infections.A recent study by the National Institutes of Health found that among nearly 660 people with severe COVID-19, a significantnumber carried rare genetic variants in 13 genes known to be critical in the body's defense against influenza virus, and morethan 3.5% were completely missing a functioning gene. Further experiments showed that immune cells from those 3.5% did notproduce any detectable immune response to the virus that causes COVID-19. Other researchers have found that blood type(also genetically determined) is associated with more severe infections. People with A positive blood types tend to be the mostat risk, and those with blood group 0 have some protection from severe COVID-19 infections.1. Using evidence from the text, how did natural selection determine the survival of Medieval humans during the Black Death(Bubonic Plague)? Please explain in 4-5 sentences. In your response, use the words: variation, natural selection, favorabletraits. This must follow a CER format (claim, evidence, reasoning)Natural selection determines the survival of medieval humans during the black death ( bubonic plague), as the variation among the genes in somehumans added the advantage of being the best suited among the population as a whole. During this bubonic plague, some mice have mutations intheir gene sequences due to the result of sexual reproduction that alters their genetic makeup leading to the variation. The survivors of this bubonicplague are those people that have survived earlier with the black death disease from Europe as their genes show resistance towards this bacterium,JAN 92784...lil
