A Level Biology Revision "Classification of Species"

You can find all my A Level Biology videos fully indexed at https://www.freesciencelessons.co.uk/...

In this video, we look at the classification of species. First we explore why the use of common names can present problems. We then look at the Linnean classification system and the use of binomial names. Finally, we explore what is meant by a species.
