Evolution (variation & selection)
A lesson in Plant Adaptations from Ms Cooper (12m 15s); Specialized Leaves, a short 1m 39s video.

What is Natural Selection? A 9m video from Stated Clearly:
How evolution works – a gentle 12m cartoon video (from Kurz Gesagt – in a nutshell) and here is Natural Selection made easy in a 9m 48s video (from potholer54).

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 biology edexcel 5.10 5.20 from Marcos Rodriguez
A lesson on Selective Breeding from Mr Dare:
Topic 3 Genetics
Here are some past essay questions:
Here are video tutorials for some assessment statements in topic 3 – more are being added all the time. Thank you to Stephanie Castle (at UNIS, New York).
Paul Andersen (from Bozeman High) shows you how to Solve Hardy-Weinberg Problems.
Here are three sites with practice Hardy-Weinberg questions: here, here, and here.
In Crash Course Biology #18 – Population Genetics: When Darwin met Mendel, Hank talks about population genetics including the Hardy-Weinberg equation.
The Hardy-Weinberg Principle: Watch your Ps and Qs – a video lesson with some practice questions.
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.
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:
Topic 10 Genetics & Evolution
Here are some past essay questions:
10.1 meiosis from Bob Smullen
Here are some fantastic animated tutorials about Meiosis from McGraw Hill Education – how Meiosis works, the stages of Meiosis, Crossing-over, Independent Assortment & unique features of Meiosis.
From Sinauer Associates comes an animated, narrated tutorial on Independent Assortment; there’s also one on Independent Assortment & gamete diversity.
Mr. Andersen uses chromosome beads to simulate both Mitosis and Meiosis:
Independent Assortment & Segregation (click to enlarge)
10.2 inheritance from Bob Smullen
An animated, narrated tutorial on X-linked disorders (from Sumanas) and a more difficult one: analyzing a cross (recombinants). Various activities on Genetic Disorders from Learn.Genetics.
Paul Andersen explains how Linked Genes behave using fruit flies in a 17m 22s tutorial.
