In a very interesting study reported by DiscoveryNews, rats were observed helping free other rats from imprisonment often even when presented with the alternative of eating a whole pile of chocolate chips.
The scientists conducting the study say the actions show that rats are empathetic. According to the conclusions, the results of the study indicate that empathy is a biologically rooted trait likely to exist in many species. This is interesting, especially considering how people used to think that humans were the only species capable of such feelings.
I wonder what assumption about our superiority over other animals will fall next.
