We kid you not: Orphaned baby chimpanzees cared for by humans in a loving, attentive manner have been found to be more cognitively advanced than some human infants.
Authors of a new study in Developmental Psychobiology compared nine-month-old human babies to nine-month-old chimps who had received daily “mom sessions.” For 20 hours a week, humans would play with 17 of the orphaned infant chimps, helping them to develop motor skills and to “meet new challenges with curiosity instead of distress.”
The chimps were then given an IQ test, the same tool normally used to assess infant human development—and those receiving all the mommy time scored an average of almost 10 points higher than normal humans of the same age. Meanwhile, the 28 chimps raised in “standard care” scored an average of 7.5 points lower.
The chimpanzees who received “responsive care” continued to exhibit strong cognitive and emotional development throughout their youth. Those who received standard or institutional care, however—in which only physical needs were met, with no social or emotional care from human surrogate mothers—were less likely to become well-adjusted adults.

The tumor on his genitals had made Henry into an old grouch. At his new home in the Southland Museum and Art Gallery, he was aggressive and unpopular with the ladies. Sure, Henry was already in his 70s—but in tuatara years, he was still in his prime.
Tuataras, a lizard-like reptile belonging to an ancient lineage that has changed little since the time of the dinosaurs, are known for their longevity. They don’t reach sexual maturity until age 20 and many have been known to live past 100.
Henry’s fortunes reversed in 2002, when at the age of 105, he underwent an operation to remove his inconvenient (and cancerous) tumor. Since then, his human caretakers say he has regained a vigor that belies his age. Whereas before the operation, Henry was often kept in solitary confinement due to his foul temper, now he is kept in the company of three female tauturas. Even so, museum keepers were surprised when Henry recently became a father at the age of 111, after a romantic romp with an 80-year-old female named Mildred.
