Section 8: Culture, Natural Selection and the Human Brain
Consider how culture has influenced our behavior and particularly our biology? For example, treating childhood diabetes allows these children to grow up, have children and pass the gene on to their offspring, also in the gene pool. A hundred years children would die of diabetes and never reproduce, thereby never contributing the trait to the gene pool and reducing the number in the gene pool. Because of our ability to keep these children alive longer, we have changed our gene pool and subsequently, our biology. Now, use your own examples.
