Life of mammals

A picture is worth a thousand words. A video is worth a thousand pictures (or may be more, depending upon the frame rate).

The clip in the following video is from the BBC series called "Life of mammals" (part 5). The song is not from the original video. Definitely watch between the time slots 2:40 to 2:50. Absolutely awesome. Anyone who sees this will get a very strong intuition on some of the biology and physics of tails in animals.

If possible, please watch the entire series. I am absolutely thrilled and fascinated to see this. I think a smart kid can work out the principles of evolution by watching this series. No irritating teachers, boring text books or painful exams will be needed. Following is the first part of the series.
