Question

Quizplus · Accepted Answer

Speciation is one of the main processes that drive macroevolution, which refers to large-scale evolutionary changes over geological time. This is because the accumulation of genetic differences between two populations can lead to the development of new species over time. Options A and B are incorrect because natural selection affects the survival and reproductive success of individuals within a population, but not necessarily the entire population. Option C is incorrect because speciation can occur on different timescales, ranging from thousands to millions of years.
