Just look at the changes in the last few hundred years!
While visiting numerous castles, pubs and houses in the UK, you can't help but be struck by the tops of the door jams. I mean, struck by how low the doors are.
I reckon that by average, we've grown in stature by at least a foot.
Looking forward though on a sadder note, I feel that we may go back to being the malnourished, undersized people from our past. Our global population is exploding, we're building housing estates on our prime coastal farmland, ( where do they grow the food now? the desert?) we're poisoning the air we breathe, the water we drink and the land we grow our food on.
What chance does the human race have of survival little own evolving?
