This is a video that explains how Charles Darwin's theory of natural selection is applied to humans. He goes on to say that human ancestors have passed down genes that have somehow aided in human survival. Different from every other case, humans were passed down the gene of prominent intelligence. This trait has kept homo sapiens the dominant species on earth since human consciousness began. This video covers topics ranging from natural selection to reproduction, all in relation to evolutionary psychology.
