Thanks for the comment.
Not entirely sure if I agree, although you may have A point to an extent.
WW1 German population was 67-68 million. So 34million males, many were too old or young so almost 2 million dead or seriously wounded for life is at least 10% of the young generation males.
WW2 90 million population but also about 4 million dead/seriously wounded also another 10% at least. So basically 2 generations almost in a row had over 10% of their healthy and intelligent males taken out of the population.
Just read 18% of Young French men died in WW1 who served, and nearly all healthy, intelligent young men were drafted.
Interesting article that does not approach the ideas of war causing selective breeding and change in genomes.

That might be enough to create a genetic drift, to what extent I’m unsure.
I believe that, too. However, our population in 1939 was just above 80 million, and the number of our military casualties has been estimated at 5.3 million (by German military historian Rüdiger Overmans, Ph.D. in his seminal work on German military losses in WW II. I don’t know whether it has been translated into English).
The losses in the last months of hostilities were particularly high, ranging up to ten thousand dead per day, but a huge share of those were “Volkssturm” child soldiers and “elder men” from 45 to 60 and over.
There even were some women soldiers during the latter phase of the war, though far fewer than in the Red Army.
