Evolution Quote by Robert M. Sapolsky
““Our prototypical behavior has occurred. How was it influenced by events when the egg and sperm that formed that person joined, creating their genome—the chromosomes, the sequences of DNA—destined to be duplicated in every cell in that future person’s body? What role did those genes play in causing that behavior?””
