I was watching a PBS documentary a month or so ago that was talking about parenting. The narrator said something along the lines of ‘the first mother that acted like a mother occurred 150 million years ago’. I’m assuming it takes an emotion like ‘love’ to act like a mother. So I’m guessing in our evolutionary history, love is only 150~ million years old.
However, how do you even define love? Or hands for that matter. I’m sure there may have been a proto-love emotion, maybe a proto-fear or proto-humor emotion. There were protohands, so it is hard to pinpoint when ‘hands’ first developed. So I’m guessing there was a protolove, so I have no idea where to draw the line.
Do you need to be a mammal to have these emotions? Do other life forms have affect like we do?
When (times periods and which animals) did these emotions first arrive in? Can affective neuroscientists and evolutionary biologists pinpoint which animal and what time period experienced the first sense of humor, or the first experience of fear or emotion of brotherly love?
Does anyone know of any books on evolution and affective neuroscience that a person with the attention span of a weasel on meth would enjoy?
