EXCLUSIVE — A study that purported to find the gene behind aggression in hamsters is now under fire for unnecessary cruelty, according to a watchdog organization.

Georgia State University scientists were "really surprised" after a gene-editing experiment led to Syrian hamsters showing high levels of aggression.

Once gene-spliced, the hamsters exhibited “high levels of aggression towards other same-sex individuals,” the professor said, regardless of sexuality or genotype.

Juveniles given high doses became somewhat less aggressive, but not as much as adult hamsters, who calmed down on both high and low doses.
