Were people shorter in the middle ages?
When talking about human evolution, I've heard several people comment that humans used to be a lot smaller, and that we can tell this by the size of the doors in old houses.
I don't believe this to be true as evolution is a much slower process.
However I've heard this so many times, I'm wondering why this has come about, and if there is any truth to it?
Is there any evidence to show a change in average height in the last 500 years or so?
