Why can formation of a new species take a very long time?
Answer and explanation
Correct answer: Because small changes accumulate over many generations
Speciation is generally a gradual process. Small heritable variations arise and may accumulate in populations over many generations. Natural selection, genetic drift, and reproductive isolation can progressively increase differences until groups can no longer interbreed successfully. Food does not instantly create a species, organisms do not all change in one day, and chromosomes are not absent. Therefore option A is correct.
