Of Mice and Men

This caught my eye. It's an article in Yahoo News entitled Humans Crave Violence Just Like Sex. I'm thinking, this has to be noteworthy. Imagine my disappointment in reading the first few lines:

New research on mice shows the brain processes aggressive behavior as it does other rewards. Mice sought violence, in fact, picking fights for no apparent reason other than the rewarding feeling.

The mouse brain is thought to be analogous to the human brain in this study...(my italics)

Pardon me my skepticism.
