Na'vi diversity

[Tsawke`Iheyu]

Shouldn't this have a genetical origin ? I mean back on Earth, people are born to grow taller than others, or to stay short during the entire life. The Na'vi don't seem to make an exception, they're born to grow tall and 3,9 is a medium height, 5,9 is a maximum height.

Based on mass figures, average females are about 90% of average male mass. But from what I see in the movie, females are much slimmer than males. Perhaps females have denser muscles? What would that imply, physically?

Yes and no - genetics plays a large part, but so does nutrition. Average height for men in Elizabethan England was about 5'5 or so - previously, I believe it was much higher, and now days it is back to being higher. That's not genetics, but plain old nutrition while growing up. That said, groups of people do tends to be taller or shorter, which is mostly where I think the Na'vi differences come in - I'd actually be surprised if they were exactly the same, over the whole planet. Humans certainly aren't, and from all implications, we're a much younger species.

...oh, now THAT'S interesting. I'll have to think about that.
