It is a fact that (on average) humans have gotten taller in the last X amount of years. Maybe there are some demographic outliers, but in general humans today are much taller than ancestors of ancient times i.e B.C. and backwards and even in the last 150 years of post-industrialisation we’ve experienced significant height increases.
I’ve read a few different things on the internet - the core reasons given are:
[li]Better nutrition[/li][li]better healthcare[/li][li]genetic mixing due to ease of travel[/li][/ul]
and I’m sure there are lots of other factors. A lot of articles I was reading use the term evolution, but I was always under the impression that evolution only works on longer time scales than a few hundred years.
So to my questions - is there an upper height limit that our genetics/DNA/whatever are limited to?
If there is not, are we expecting humans to grow and grow more, on average? and what is the new average going to be in time n + x years?
I’m relatively tall, and I’m attracted to tall women. My fiance is nearly 6ft. Our kids will therefore likely be tall, and if they also marry tall people and have kids etc then will that drive us towards really large averages in the future?
