Juvenile nutrition greatly affects height.

(Is human evolution finally over?
Scientists are split over the theory that natural selection has come to a standstill in the West)
It’s not even darwin-ism. It can’t be.
No one is going through natural selection because of an extra artery in their fore-arm. No one is surviving better because of it and no one is having more babies because of it. It probably has more to do with change in the diet and nutrition of mothers during pregnancy over the last several centuries.
Easier to sneak into a house when you are of a slight build.
In the future we will ALL throw a baseball at 150 MPH.
When I was young I held a job for a time in a building that was constructed around 1870. I am 5’ 9” and I had to duck to get through most of the doorframes.
I went to Jamestown settlement in Virginia when I was about 12. We went on board the ships that the settlers rode on from England. I had to duck to get around below decks. The tour guide told us that most of the people back then were all about 5 foot tall.
On a whole I agree with you that people were shorter.
However this “data” probably is not representative.
I imagine these people grew up under very tough conditions, probably lacked nourishment during their growing years. So this group being “stunted” in large numbers is not surprising.
Especially Custer. He was a whack job.

I once had someone tell me he knew evolution had to be true because people were getting taller - really. I had to explain how diet and nutrition works to him. He was a high school teacher - and of course, a devoted liberal.
terrible nutrition.

Our great great-grandchildren will be 20 feet tall, thanks to Chuckles Darwin. If the NBA ever goes back to normal, the games of 2050 should be amazing.
Any natural selection happening here?
That is genetic selection. Not evolution.
No genetic information is being added.
Not evolution. Its not new, just not regressing as commonly as before.
Might be beneficial, and still not evolution; no new genetic material that is favorable that wasn’t there before. Like a human with night vision.
God put it there.
Epigenetics is a reasonable to answer to what we are seeing. Thanks for reminding me of that.
It seems like those living in their parents' basement playing Nintendo would be less likely to pass on their genes. :-)
Maybe the medial artery helps raising the middle finger.
Agree. Let me know when someone grows wings.
