I found out a few weeks back that samurai were only 5'2-5'3(157cm-160cm). I started checking other groups height and found out literally every group was around 5'5(165cm) or smaller on avg with few exceptions yamnaya steppe who are said to be around 5'10(178cm). I found height increase data in rich countries.

South korea height was reported to be max 5'5/165 cm on avg in 1950s. Now its reported young adults in south korea are close to 5'9(175cm).

European were also at the same level in 17-18 century there avg is 6 ft in some countries.

Whereas poor countries like India have stayed exactly where they were before 5'4-5'5.

Europe seems to have reached its peak height as not much height increase is noticed in new gen in some countries avg is believed to have fallen(due to immigration?). But my question is would korea eventually reach european height as europe has been rich for centuries now.

Or is it european will be few inches taller due to yamnaya steppe ancestory.…
