It's no wonder a tortoise is born a sociopath. Their mom burys them in the ground and takes off...no wonder they love almost everyone but another tortoise...
When tiny humans are born they are born sociopathic and narcissistic. Survival instinct is all that is known until the brain develops enough for the baby to learn empathy from the mother. Natural basic emotions begin to become present also. Basic emotions and gestures are universal which suggests that basic emotions and gestures are innate. Pretty interesting. I would love to see videos of everyone's tortoise interacting with them.
