Okay. I decided to check with relatives. I could be misremembering. The relative suggested I checked the Smithsonian's web site.
So, I did.
From the Smithsonian/National Zoo:

Scientists are hotly debating these questions, but one thing is clear: differences between humans and other primates arent as black and white as once was thought. Intelligence appears more a matter of degree, developing gradually throughout the primate lineage rather than sprouting magically when humans first arrived on the scene. Many of the features of our brain that support higher cognitive functions, such as language and mathematicsor at least their precursorsmay well be present in ape and monkey brains, and in the brains of long-extinct relatives like the Australopithecines.
