Height is only 40pc hereditary – the rest is nurture
Study finds nurture-based traits like environment, upbringing and quality of life has greater influence over how tall a person becomes
We’ve known that for a long, long, time. Soldiers being 6 inches shorter than officers in 1914 for example. Childhood nutrition and stunting.
Even, that it’s very difficult to tell social class in the UK from height these days. Something that wasn’t true that 100 years ago.
And here in Southern Europe you can still tell social class – not exactly, obviously – from height in the older generations. Different generations in different countries too – the inability to tell coinciding with the arrival of adequate childhood nutrition for all. That leap off point in economic development. Perhaps the 1960s for Southern Italy, the 1980s even for Portugal.
That we know more of the details now is nice but the basic idea is old, old.
