Here’s Darwin’s Song from Horrible Histories and in What is Evolution? Biology teacher Ceri Evans gives a master class to students on what he says is arguably the greatest idea anybody ever had: evolution (28 mins). 2 more videos – James May’s things you need to know – Evolution (29m) & BBC Short Circuit Theory of Evolution (19m).

Finally, just for interest, a short (less than 5 minute) video clip from BBC iScience – Evolution of the Eye.

SELECTIVE BREEDING (ARTIFICAIL SELECTION)

This powerpoint covers Artificial Selection (selective breeding) – but we only need the first five slides:

IGCSE Bio Topic 17 – Inheritance

Here are key terms and some definitions: Key Terms B9

GCSE Bitesize more-or-less covers all of Variation, Inheritance & Evolution in 15m.

For self-assessment questions, with exercises and discussions, just click on the correct topic at Biology GCSE & IGCSE Question Bank. A powerpoint can be downloaded from the same site here. The s-cool revision site lets you revise the topic, summarizes the topic & tests you on it. GCSE Bitesize has revision pages (that take you through the topic), a test and an activity.

Here’s Penguins in peril: Inheritance – know your genetic jargon & ratios:

Play this game on the what2learn site

This is a great power-point that covers most of this topic, although we don’t need to know about co-dominance or pedigree charts:

A short, simple explanation of Mendel’s work:

Mr Andersen talks you through Genetics:

And here Paul Andersen introduces A Beginner’s Guide to Punnett Squares in a 12m 15s tutorial. He also gives examples of monohybrid crosses and one example of a dihybrid cross (which we don’t need to know for SL).

An animated, narrated tutorial on Mendel’s experiments &  genetic crosses from Sinauer Associates.
In Crash Course Biology #9 – Heredity, Hank and his brother John discuss heredity via the gross example of relative ear wax moistness.
