Variation is a characteristic that can be inherited. Every organism group overproduces offspring leading to a struggle for survival. Individuals with favorable characteristics are more likely to survive, passing their genes leads to evolution. - ️️Theory of organic evolution by natural selection The male semen was only formed from the blood ~ provides "form" The female menstrual blood contains the "matter" The "form" controls and shapes the "matter" into mature ...
