A piece of clay comes from a mountain and is pressed into a mould, then thrown into a river and melts, it lands at the end on a rock, squished. Why is it that shape? To say, "because of the chemical composition of the mountain" is, at the very least, foolish. Organic lifeforms are self-modifying clays that are pressed into environmental moulds. Genes play both a far more complex, and far simpler role, in this than the mid-20th C. eugenicist biological science supposed. A pseudoscience that still predominates in how people think about genes, and in many downstream research areas (eg., https://slatestarcodex.com/2019/05/07/5-httlpr-a-pointed-review/ https://slatestarcodex.com/2019/05/07/5-httlpr-a-pointed-rev... )
