Why Europeans are getting taller and taller, and Americans aren’tJan 14
This is an interesting article, particularly if you’re interested in creating alien races. People in the Netherlands are growing taller (six feet one is the average for men). The article points out that it’s probably because they lead healthier lives and have better nutrition.
When I read about alien races, I like to understand why they’re different from humans. Evolution selects the fittest, so if someone is taller, shorter, has four arms or knees that bend backwards, there has to be an evolutionary explanation. In short, their design must fit their environment or be explained by their environment. Otherwise, it’s just a neat anomaly that’s likely to bug the reader. I Know it bugs the heck out of me.
