Rakish Angle on Rodent Research
It wasn’t so disconcerting to learn that wild chimps use tools for eating, grooming, and defending themselves.

In an experiment conducted with a group of six degus (cousins of the guinea pig), scientists placed sunflower seeds just out of the rodents’ reach on the other side of a Lilliputian picket fence but provided the animals with tiny rakes. By the conclusion of the 60-day study period, all the degus had figured out how to pull the seeds within reach by using the miniature garden implement.
