I made a trip to Amsterdam a couple of years ago. One of the places that I hit on the city tour was the Rembrandt house. It came into existence around the 1630s. It’s an odd structure...ceilings are exceptionally low, and the doorwalls are a good six inches lower than what you are accustomed to. This came up in the tour conversation.
Oddly....people were shorter in this period. Since the 1800s....houses in Europe have had a higher ceiling and doorway. Reason? The only logical reason is that people are getting taller...through diet and changes in the body.
You can avoid the evolution of this...until you see the room and envision people are mostly all mostly a couple inches shorter than six foot on the normal scale. Then you start to ask questions. They did this without modern science, hormones or drugs.
My humble guess is that in 200 years...ceilings and doorways will be another couple of inches higher than today.
You do know that they are still dogs, and still horses? Goats have been bred to lose their ears in the Alps, to grow ears like elephants in Africa. Coats have coats like cashmere, or have long curly locks like angoras (mohairs).
But these goats are still goats. Just because "selection" is by accident, doesn't make it evolution.
How sad, what schools are doing to people. Causing them to devolve into heartbreaking ignorance...
Children that grow up in high density cities are smaller in all dimensions than people that grow up in the countryside. It’s not just their bones but their organs as well, including their brains. The average Republican is taller and smarter than the average Democrat, which explains many things.
Why is it assumed that the bigger and/or taller you are the more evolved you are? It is more a matter of survival qualities (within a species). At a given time and place larger people may survive and flourish over smaller people. At a different given time and place smaller people may have the advantage. One, though, is not inherently more “evolved” than the other.
Good nutrition is not necessarily genetic change.
The US had tallest folks in the world after WWII. Now it is the Netherlands. US has too many immigrants from poor nutrition areas.
