The other thing about natural selection? It doesn't automatically lead to evolutionary change. Many times it's temporary. Our DNA still holds the code for a diversity of features.

Like the moths in England, the famous study that became the first proof of observed evolution in action.

These moths populated a forest near where some factories were built. They were light colored as a form of crypsis to hide from bird predation. They could also be dark colored, but the density of dark moths was very low. Why? Because most of trees in the forest had light colored bark. The dark moths were easier to spot by the birds.

When the factory went up, it started oumping outback lot of smoke and soot that made it's way to the forest. The soot stainless the tree trunks over time. As that happened, the population shifted from predominantly light colored moths to predominantly dark colored moths. Same species. Different variation due to natural selection because now the lighter colored moths were easier to spot.

Time goes by. Some of thr factories close and others find cleaner ways to deal with furnace exhaust. Slowly the tree trunks loose that soot staining, making darker colored moths easier to spot again. The population shifted again.

That forest is still there and those moths are still being observed periodically. There is still a variation of color in the moth species and environmental conditions still dictate the spread within that forest.

Natural selection can shift populations back and forth without leading to permanent evolutionary change.

Right now, as humans, we seem to be shifting back to more of what is natural for us without the falsely applied "evolutionary pressure" of dominance hierarchy. False because there never was anything truly evolutionary about dominance hierarchy. It's disadvantageous to the species. It's all cultural socialization that started with the abstract idea of owning land. There's never been anything natural about it.
