Fig trees are a keystone species in the world’s ecosystem and their fruit played a direct role in our ancestors’ rapid brain development. Humans are only one result of how an ecological framework fosters evolution. We still share genetic coding with a myriad of creatures, even the tiny Barbigant’s pygmy seahorse. At 6 to 7 weeks during human fetal development, the embryological similarities are clearly visible. As our environment nurtured our ontogeny, now our dominion makes us beholden to this fragile web of life.
