How did Charles Darwin explain inherited variation and artificial selecton?
Darwin said that artificial selection was when nature provided the variation, and humans selected those variations that they found useful. Inherited variations are differences that are passed from parents to offspring
Which two important factors was Darwin unable to explain without an understanding of heredity?
First, he had no idea how heritable traits pass from one generation to the next. Second, although variation in heritable traits was central to Darwin's theory, he had no idea how that variation appeared.
Explain why variations are needed for natural selection to occur?
Certain variations are more likely to be passed on to future generations than others, because those variations help their possessors reproduce more successfully. Other variations are less likely to be passed on because they do not help, or even hinder their possessors in successful reproduction. We say that the helpful variations are selected by the very nature of things. Without variation, whether an organism reproduces successfully or not is just a matter of blind chance. There is no natural tendency for certain individuals to be more successful at reproducing than others, because there are no differences between individuals.
