The UV rays cause sun spots due to reaction from the radiation.
Genetic drift occurs when there is no random mating across a population. This causes a change in allelic frequency due to a random sampling of the population.
As the aboriginal population explored the earth, a small part of the population became geographically isolated either due to continental drift and climate changes. As the isolated population grew bigger, they established their own gene pool. This resulted a change in genotypic frequencies from that of the aboriginal population.
I’m sorry but do you want me to answer all of these I just need a yes or no I’ll answer in the comments (:
