Hi there, I come from a family that is very tall!
My family are a mix. My Dad and brother are 6'4" and my Mom is 5'2"!
That's neat, when populations share genetic background and environmental factors, average height is often used as a characteristic within the group.
Are taller people more prevalent than little people? Or is there an even spread?
I would suspect taller people are more rare. Mainly because in regions of poverty, environmental factors during childhood/adolescence may result in delayed growth or reductions in adult stature.
