Answer 2

Answer:

The topic of emotion and evolution typically brings to mind Darwin’s classic treatise, Emotions in Man and Animals (Darwin, 1872). In this book Darwin sought to extend his theory of natural selection beyond the evolution of physical structures and into the domain of mind and behavior by exploring how emotions too might have evolved. Particularly important to his argument was the fact that certain emotions are expressed similarly in people around the world, including in isolated areas where there had been little contact with the outside world and thus little opportunity for emotional expressions to have been learned and culturally transmitted. This suggested to him that there must be a strong heritable component to emotions in people. Also important was his observation that certain emotions are expressed similarly across species, especially closely related species, further suggesting that these emotions are phylogenetically conserved.

With the rise of experimental brain research in the late 19th century, emotion was one of the key topics that early neuroscientists sought to relate to the brain (see LeDoux, 1987). The assumption was that emotion circuits are conserved across mammalian species, and that it should be possible to understand human emotions by exploring emotional mechanisms in the non-human mammalian brain.
