The Scientific Importance of Groundhogs

Tomorrow we have the only holiday dedicated to a rodent. Groundhog Day is actually about the weather, which we are more interested in than rodents this time of year, but in the United States, we have designated the groundhog as the animal most likely to forecast the weather for the rest of the winter.

The species Marmota monax goes by many names, but they are mostly called groundhogs these days, especially since that 1993 movie made the creature world famous. Groundhogs have been important in science, but not so much in meteorology. Groundhogs aren't all that great at weather forecasting. However, they have made a name in archaeology, since they are experts at digging, and in medical research, where they shine as research subjects. Savannah Geary of SciShow explains how valuable groundhogs really are. There's a 40-second ad at 3:33. The video actually ends at 8:32, but you'll be glad you continued watching after that. It will eventually make sense, except for that part where she takes a swig of what appears to be pickle juice.
