From the top of my head (don’t cite me): I don’t know what the wild fruit looks like. Maybe humans bred it to contain more seeds and thereby made it bigger. Another idea would be that difficult to open leads animals to carry it further and therefore spread the seeds further. Yet another idea: maybe to skin was supposed to fall apart but humans bred it to be stronger or harvest it before its really ripe? All just ideas.
