Watched the movie for the ~7-10th time after a year or so, and was thinking about diversity, how everything evolved etc. It's amazing how many of the animals on Pandora evolved to have 6 limbs and 4 eyes, and lights (plants with lights too). The trees communicate with each other on a next level to what we have here on Earth. Some of our trees can warn other trees of predators which then makes them activate their defense mechanisms. Other Earth trees can send nutrients to other trees, sometimes old trees do it to young trees. I recommend reading "Hubert Reeves Explains Biodiversity" (and the rest of the series), or just learn a bit about biodiversity in general as it is so important into creating such diverse environments, the closest environment we have here on Earth where it is super diverse and has the opportunity to evolve relatively fast would be the Amazon I imagine. ( Unfortunately the Amazon gets cut down a lot for the sake of Animal Agriculture which is to feed non-human animals a lot of plants so human animals can then eat the non-human animals. but there is hope as people are catching on to the environmental destruction which consists of ocean dead zones, deforestation, greenhouse gas emissions, etc. etc. also how it uses a lot of our anti-bionics, and also creates viruses/flu, and also the consumption of animal products leading to health problems.)

Back to my main question, How does something like eywa & spirit tree evolve to be? It makes me wonder. What if an advanced civilization planted the foundation for it? or maybe it is just many times more years of evolution without moving towards developing cars and electronics. They didn't have it in them to develop roads and cars and all these technology booms/revolutions just like many of Earth's aboriginals today. Nature provided all that they needed I guess, especially as their nature is way more diverse/rich allowing for all sorts of materials and "natural useful technologies" to be looted.

This begs another question, as pretty much all the non-humanoid-animals shown (the "horses, dragons, black tiger, monkeys, hammer heads") have 4 eyes and 6 limbs. Why is it only the Na'vi with 2 eyes and 4 limbs? did they evolve from an older monkey and have lived for a very very long time? The Na'vi / indigenous-humanoids lived for so long that other animals kept evolving and started having 4 eyes and 6 limbs. This huge duration of time could explain how the Na'vi developed or evolved Eywa and it's soul trees.

Also noticed how the bad guys always say stuff like "look at all this fresh meat" "roll-in the cart of meat" "look at all this cheddar", "Gas them out; it will be humane". Which I now think is animal rights activism because nobody wants to be like these idiotic bad guys and saying stuff like that but also just that they represent animal agriculture in a way too which these days I've come to learn is pretty much an animal slave industry or an animal holocaust. Jake Sully hunted, "At least I know where that came from".

James Cameron is an animal rights activist as you probably know. We activists often care about the environment too which is easily tackled when you don't eat animal products, and it's also a lot better for our health (science safely says you live a decade longer by not eating animals, hinting that it is probably more but we need more science to preach that). If you love this movie so much, you should consider the director's views, listen to what he has to say. His Twitter- https://twitter.com/JimCameron
