We know that a Coconut's (Cocos nucifera) fatty acid profile has a composition of about 90% saturated acid. I'd like to know why, what is the evolutionary sense? Why peanuts, avocado have many unsaturated fats and coconut does not?
Coconut is k-selected; a lot of energy is put into the enormous seed. The seed is capable of dispersing over great distances. When carried on ocean water, the seed commonly alights in a nutrient-poor environment. So I think its high saturated-fat content is adaptive in some way for this dispersion strategy.
