Prompt: Evolution is the process by which modern organisms have descended from past organisms. It can cause organisms to look alike or create life with a great amount of diversity. Why do some organisms evolve quickly, while others evolve slowly? Is evolution a matter of chance, or are their specific factors that lead the way for evolution to take place? Using at least one credible online source, research two evolutionary mechanisms of your choice. A mechanism is a process or technique for achieving a set result. Using the evidence from your research, explain how the mechanisms that you chose can impact the evolution of a species.

Astudy by solloch and et. al., in 2017, gives the map above which shows the frequency of alleles with a ccr5-delta32 mutations over 87 different countries. this mutation deletes the presence of a co-receptor (ccr5) on the outside of human t-cells (lymphocytes). some viruses, such as the one responsible for the black death and human immunodeficiency virus (hiv), require this receptor for attachment to host cells during the infection process. the black death was an epidemic that passed over northern europe during the 14th century killing nearly 60% of europeans. according to this information, which explanation best explains why northern europeans show a greater immunity for hiv than some other parts of the world?
