And they happen, on average, to have a certain unique physiology: legs that are very long and very thin at their extremity, and this is because they have their ancestry at very low latitude in a very hot and dry climate, and an evolutionary adaptation to that is limbs that are very long and very thin at the extremity for cooling purposes.
I događa se da oni, u prosjeku, imaju određenu jedinstvenu fiziologiju: noge koje su vrlo duge i tanke na ekstremitetima, i to je zato što imaju pretke na niskoj širini u vrlo vrućoj i suhoj klimi, i evolucijska adaptacija tome je da su im udovi vrlo dugi i vrlo tanki na ekstremitetima da se rashlade.
