Did you know that all the hamsters in the United States, all the different shapes and colors and sizes, all came from a single brother and sister pair brought over from Turkey in the 1930's? Did you know that hamsters are endangered in the wild? Even better, did you know that female hamsters are active during the day in the wild, instead of up all night like they are here? I sure didn't until I caught this post about hamsters at the Urban Science Adventures blog. Note for parents of squeamish children: the video clip does talk about how the farmers kill hamsters.
