Here's four-and-a-half minutes of possum groin! Our Ohio University Honors Tutorial College dissector extraordinaire Emily Caggiano did a really nice dissection of the epipubic bones and associated muscles of a Virginia opossum, so I thought we'd share what she found. OU professor Steve Reilly published an article in Science in 2003 on how these epipubic bones—and their loss in placentals—relate to the evolution of locomotor modes in mammals. Steve and his team later went on to show that these changes are also coupled to the respiratory system, but Emily and I just focused on the locomotor aspects in the video. Check out the whole Dissecting with Emily series with this playlist: youtube.com/playlist?list=PLp0K9wSdRtLIat051zcg3i_nhokGCA6Pr.
