5.2 Natural Selection

BioKnowledgy 5.2 natural selection from Chris Paine

What is Natural Selection? – a 9m 19s video from Stated Clearly:

Darwin’s Natural Selection – explained in a 4m 3s video:

Find a video lesson on this sub-topic at Dan Rott videos.

Fantastic animated tutorials from McGraw Hill Education – Mechanisms of Evolution (five of them) & a simulation of Genetic Drift.

An excellent narrated tutorial on Evolution – the big picture which includes evidence for evolution (from Sinauer Associates).

Natural selection interactive simulation from PhET (University of Colorado) and here is more information and a peppered moth game.

In Crash Course Biology #14 – Natural Selection, Hank guides us through the process of natural selection, the key mechanism of evolution. Hank’s brother helps him present The Evolutionary Epic (Big History#5). Darwin and Natural Selection (Crash Course History of Science #22) in 13m.

Paul Andersen explains Natural SelectionMicroevolution and details Examples of Natural Selection.

Key terms as flashcards from Quizlet (you also can test yourself in a number of ways):

Human Evolution

D3 Human Evolution notes – these are taken from BioNinja (with thanks).

Timeline of Human Evolution – from 530 mya – interesting but not useful for the exam (3m 28s):

Here’s another power-point (a bit more detailed than above):

Hardy-Weinberg Principle

D4 The Hardy Weinberg Principle notes – these are taken from BioNinja (with thanks).

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.

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:
