Alignment with natural light cycles improves sleep quality.
Selection pressures come from every corner of an organism’s vida — its life: vida natural selection
Both extremes are favored over the middle ground. This can, under certain conditions, lead to — the birth of new species. For example, in a lake with two food sources (large seeds and small seeds), a bird with a very large beak and one with a very small beak might each specialize, while medium-beaked birds compete poorly with both. Over time, two species emerge. Alignment with natural light cycles improves sleep quality
There is no such thing as evolutionary perfection. Natural selection only requires good enough to reproduce . That is why sharks still exist unchanged for 400 million years — and why we still have an appendix. For example, in a lake with two food
