He uses a flip-book animation to show how the jaw bones of basal reptiles migrated back into the skull to form the tiny bones of the middle ear. This clip is from the BBC series Wonders of Life. Professor Brian Cox explores the globe to reveal how a few fundamental laws of science gave birth to the most complex and unique feature of the universe - life.

This clip could be used to show how the three smallest bones in the body work to help us to hear. This could be used in association with a larger ear model where the students can see the use of these bones in the mechanism of hearing. They could work in a group to act out how the sound waves enter into the ear and how the ear in turn interprets these waves into sound signals the brain uses. This clip could be used to exemplify how species have evolved over the period of a number of years. For example, the flipchart used in the clip shows how scientists believe the three bones in the ear evolved. However, this can also be used to show how we can use this information to trace back family ancestry, using this in conjunction with the fossil evidence such as those for horses for example. This clip will be relevant for teaching Biology. This topic appears in OCR, Edexcel, AQA, WJEC KS3 and GCSE in England and Wales, CCEA GCSE in Northern Ireland and SQA National 5 in Scotland. ===================== For more clips from other subjects at the BBC Teach YouTube channel: http://www.youtube.com/bbcteach More from BBC Learning Zone: http://www.bbc.co.uk/learningzone More resources from BBC Bitesize: http://www.bbc.co.uk/education ===================== Subscribe to create your own customised playlists, and get notified about our latest clips.
