Product Description

Natural Selection: One Example.

Populations are never identical; there are differences among individuals. When individuals with certain traits leave more offspring than those without them, the average over the population changes: the population evolves.

Assume a population of giraffes with the same number of long-necked and short-necked individuals. The short-necked giraffes will face a disadvantage when reaching for leaves from the trees.

Long-necked giraffes will leave more offspring who will inherit their long-neck genes. Eventually, the number of long-necked giraffes will be greater than the number of short-necked ones.

As time goes by, all short-necked giraffes will disappear The whole population will have long necks, just as it happens today.
