Material List

  • 1Pair of Tweezers

  • 5Once sorted, you can observe and see some similarities between the bone structures of rodents and humans.

How It Works

Since owls don’t have teeth, they swallow their prey whole. The undigested bones and fur are then regurgitated as a pellet, which is a great place to look for the bones of rodents. A rodent's bone structure, along with many other organisms, are very similar to humans. For example, the arm of both a rodent and a human have the same pattern: One bone in the upper arm, connected to two bones in the forearm, which is connected to a bunch of little bones in the wrist, and those bones are connected to fingers. This is one piece of evidence that we may be related.
