The Evolution of Populations: Natural Selection, Genetic Drift, and Gene Flow
After going through Darwin's work, it's time to get up to speed on our current models of evolution. Much of what Darwin didn't know is now known and understood very well, so we can meticulously go through much of the evidence we see for evolution, as well as some of the ways that it propagates other than natural selection.

Mykola Kobzar on Instagram: "At the ends of vour chromosomes are protective caps called telomeres. They're like the tips of shoelaces--thev prevent DNA from fraying. Every time a cell divides, telomeres get shorter. When thev're too short, the cell dies. These are the biological clocks of aging And scientists discovered something shocking stress speeds up this clock dramatically. But one inner state can trigger the reverse process. 5 facts that will change how you see stress: 1. Elizabeth Blackb

Mark Hyman, M.D. on Instagram: "FOOD = CODE that reprograms your body in MINUTES! Every bite you take is literally rewriting your gene expression, hormones, brain chemistry, and immune system. Most people have NO IDEA their symptoms are caused by what they’re eating. I just had an amazing chat with @jayshetty, breaking down: - Why 93% of Americans are metabolically broken - The difference between medicinal vs inflammatory foods - How ultra-processed foods reprogram your biology for illness + I’m
