Boysen

Sally Boysen has been studying chimpanzee cognition for over 30 years. A psychologist at Ohio State University, she has focused on chimps' ability to understand numbers and tools, their ability to recognize loved ones, and their seemingly altruistic natures. In the near future, she hopes to teach them to read simple English words. She also really loves her chimps.

Another Rubus character of particular interest is R. ursinus × idaeus, or boysenberry. This is a complex hybrid which came about as a cross between European raspberry (R. idaeus), common blackberry (R. fruticosus), and loganberry (Rubus × loganobaccus). The hyrbid was originally developed during the late 1920’s in California by a farmer named Rudolph Boysen.
