The ancestors of modern Europeans arrived in Europe at least 40,000 years before present. Pre-glacial maximum Upper Palaeolithic males (before 16,000 BC) were tall and slim (mean height 179 cm, estimated average body weight 67 kg), while the females were comparably small and robust (mean height 158 cm, estimated average body weight 54 kg). Late Upper Palaeolithic males (8000-6600 BC) were of medium stature and robusticity (mean height 166 cm, estimated average body weight 62 kg). Stature further decreased to below 165 cm with estimated average body weight of 64 kg in Neolithic males of the Linear Band Pottery Culture, and to 150 cm with estimated average body weight of 49 kg in Neolithic females. The body stature of European males remained within the range of 165 to 170 cm up to the end of the 19th century.

I think natural selection is the answer to your question. When in cooler climate shorter with shorter appendages is a usefull trait as it takes less energy to heat etc.
I would think in warmer climates a taller more slender frame would attract less and dissipate heat better than the stocky fellow above.
That's my guess anyway, the simplest answer is usually the right one.

In terms of size, smaller vertebrates are more likely to survive cataclysm.
Big eaters and species that have very small numbers of offspring die off first.
So, Rats will probably be the next intelligent life on Earth. Give it about 1M years after homo sapiens are out of the way.

Then how do you explain the explosive growth in height the last 100 years. Is it all because of nylon and the tall dark fella? Seeing beds and doorframes from a few centuries ago, well, they were in the hobbit department.

There's more of it, but more nutritious? Seriously? I don't buy that. Was royalty significantly taller than peasants, or simply more likely to be overweight/obese?
