of mice and men

From the BBC:
A chemical in the brain controls sexual preference in mice, according to scientists in China.

“The research team first bred male mice whose brains were not receptive to serotonin. When presented with a choice of partners, they showed no overall preference for either males or females.”

“When just a male was introduced into the cage, the modified males were far more likely to mount the male and emit a "mating call" normally given off when encountering females than unmodified males were.”

“However, a preference for females could be "restored" by injecting serotonin into the brain.”


“Experts have warned about the dangers of drawing conclusions about human sexuality.” 
Unless, y’know...
