Empathy, Emotional Resonance, or DNA?
By Lee Charles Kelley...
In an online discussion, neurobiologists J. David Jentsch and Dario Ringach — both from the Geffen School of Medicine at UCLA — offered several alternative interpretations of the data, which don't require that the rats exhibited empathy or behaved in an altruistic manner.
Evolutionary psychiatrist, Jaak Panksepp — writing in the same edition of Science Magazine that published the rat-empathy paper — points out, "It is unclear whether the rats sympathize with the distress of their cage-mates, or simply feel better as they alleviate the perceived distress of others."
