“The first and most basic evolutionary point is that the primary targets and beneficiaries of sociality are the offspring. Why? Because mammalian babies are immature at birth and will certainly die without care. Baby turtles, after hatching from their eggs, immediately dig their way up out of the sand, scuttle down to the water, and begin to look for food. No parents are anywhere close by, nor are any needed.” — Patricia S. Churchland
