  • Chimpanzees 黑猩猩

    Chimpanzees are our closest living relatives. We share almost 99 percent of our DNA1 with them. It turns out that they share some of our brain power as well. In a study published in 2007, researchers gave adult chimps2, adolescent chimps, and college students the same cognitive3 test. The exam involved remembering where a list of numbers—from one to nine—were located on a touch screen monitor.


    Chimps and humans alike saw the numbers in their locations for less than a second. Then they were asked to remember where those numbers had been and show the researchers. The adult primates4 and humans performed about the same. But the adolescent chimps left them both in the dust. They remembered each number’s location with far better accuracy. Researchers think that these youngsters were using a type of photographic memory, which allows an individual to recall images with extremely high accuracy even if they only glanced at them for a split second.


    Goats 山羊

    Scientists have thought for a long time that goats are far smarter than their unassuming demeanor5 leads many of us to believe. Finally, a group of researchers in Australia decided6 to put these barn animals to the test. To do so, they set up a contraption that held fruit at the end. To access the tasty treat, the goats had to use their teeth to drag a rope down, which activated7 a lever they had to lift up with their mouths. If they could figure all that out, the fruit was theirs.


    Nine out of 12 goats mastered the task after around four tries. When the researchers had all the goats try again 10 months later, the majority still remembered how to work the system.
