This week, Amber's under the weather, so Anna goes solo with special guest Dr. Naomi Martisius. Naomi tells us how she deciphers clues about human behavior by looking at tiny tiny VERY tiny portions of animal bone surfaces under a microscope. We’ll get into her undergraduate discovery that re-wrote a part of prehistory (no, really), and her work on the extremely cool bone artifacts and ornaments from Bacho Kiro Cave, in what is today Bulgaria.
