Question	—	Tall trees : selective pressure Thousands of years ago (approximately 12 000 years), a group of humans (let's call them First Group) reached out and settled in forests with huge trees (Tall trees : atmospheric pressure) which made them "evolve" (I know that the time lapse is too short for talking about evolution) a little bit diffe...

Question	—	Tall trees : atmospheric pressure In my previous post, I asked about how tall trees could grow in my world. To be honest, I really need those trees to be huge for my storie, because a big part of the plot will be linked to those big forests, so every characteristic of my world are settled for those trees to grow as big as possible (b...

Question	—	How tall would animals, trees and "humans" grow on a planet with those characteristics? I am working on a planet were life (trees, plants, food, animals, humans) would be bigger/taller than Earth. I have learned that oxygen level or gravity, for example, could help change the size of life forms. So here are the characteristics of the planet : Nitrogen : 72,4%, Oxygen : 26%, Argon : 1...

Question	—	In what ways a higher level of oxygen (23 to 25%) and higher pressure (1,7 time the earth air density) would affect winds and ocean currents? From some research, I have learned that atmospheric circulation - winds currents and ocean currents - depend on pressure and the Coriolis effect. But if the oxygen level is increased and the pressure is higher (as said in the question), how much would this effect be modified ? (more)	—	about 5 years ago
