The gene that causes sickle-cell disease is present in a higher percentage of residents of sub-Saharan Africa than among those o
Ivanshal [37]

Ans.

Sickle-cell disorder is a genetic disorder, which shows defected red blood cells, due to mutation in the genes for hemoglobin protein.

Malaria is common in sub-Saharan Africa region and there, natural selection favored gene for sickle cells, because it might be beneficial to people having sickle cell disease that makes them able to survive in such condition and transmit their genes to offspring.

On the other hand, in those Africans, who moved to United States, where malaria is uncommon or absent, natural selection favored normal, wild type genes, resulting in fewer people with defected sickle cell.

Hence,  sub-Saharan African population shows higher percentage of mutated gene for sickle cell as compared to population of United States.

Thus, the evolutionary process behind this difference is 'natural selection.'

How does earths magnetic field provide evidence for seafloor spreading
REY [17]

Magnetic reversal proves seafloor spreading because we can see the polarity of the Earth's magnetic field in rocks. As magma cools, particles in it get “frozen” in the direction of the magnetic field. ... The magnetic evidence shows that the oldest rocks are far away from the ridge and the newest rocks are closest.
