Bee from Essig Museum Collection (IMAGE) University of California - Berkeley Caption Specimens like this 47-year-old honey bee from UC Berkeley's Essig Museum collection can help researchers understand how plant and animal populations have changed over the past 100 years. The pollen in the basket on the bee's hind legs is very robust over decades and can provide information about what plants were growing where the bees foraged. The bee's DNA can tell how insect populations have changed over the last 50 years.
