Topic 5 Evolution & Biodiversity

What is Evolution? – an 8m 53s video from Stated Clearly:

Some excellent interactive animations & tutorials on Variation & Evolution just click on Variation, Selection & Time at the bottom of this page (Learn.Genetics).

In Crash Course Biology #20 – Evolution: It’s a Thing, Hank gets real with us in a discussion of evolution – it’s a thing, not a debate.

Myths and misconceptions about evolution from TED-Ed.

Paul Andersen (from Bozeman High) explains Microevolution.

The whole topic in one powerpoint (if you want):

IB Biology Evolution 2015 from Bob Smullen

The Evolution of Life on Earth in 24 hrs – a 2m 19s animation from AsapSCIENCE:

5.1 Evidence for Evolution

BioKnowledgy 5.1 Evidence for evolution from Chris Paine

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

What is the Evidence for Evolution? An 11m video from Stated Clearly:

Proof of evolution that you can find on your body, a 4m video.

Paul Andersen (from Bozeman High) describes pieces of Evidence of Evolution that Charles Darwin used to support the idea of evolution and his process of natural selection (and here is a similar lesson: Evidence for Evolution).

A 2m 30s video on one example of intermediate fossils as evidence for evolution from Richard Dawkins:

The science of evolutionary developmental biology, a song from A Capella Science:

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:

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).

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

5.3 Classification of Biodiversity

If you’re revising, don’t waste your time watching this –  what is the true call of the wild? Here we travel down a very special river and are introduced to a wide variety of the animal kingdom who all contribute their name for the sake of music:

BioKnowledgy Presentation on 5.3 Classification of biodiversity from Chris Paine

IB Biology 5.3 Slides: Classification & Taxonomy from Jacob Cedarbaum

A couple of introductory TED-Ed videos: the secret life of plankton (6m) and how life came to land (5m 27s).

Classification of Living Things (4m):

An animated tutorial from McGraw Hill Education on the Three Domains and here is the tree of life: the ancestors’ tale in OneZoom.

InThe Classification of Life, Paul Andersen explains the goal of classification as well as its history (you won’t be tested on this but it’s important) and in The Three Domains of Life he describes the three domains.

In Crash Course Biology #19 – Taxonomy: Life’s Filing System, Hank tells us the background story and explains the importance of the science of classifying living things. In #22 – Simple Animals: Sponges, Jellies & Octopuses, Hank introduces us to the “simplest” of the animals and in #23 – Complex Animals: Annelids & Arthropods, Hank continues our exploration of animal phyla with the more complexly organised annelida and arthropoda.

The three different ways mammals give birth, a TED-Ed lesson in 5m.

A quiz on Plant Classification (good luck!).

The importance of classification – woodlice names in the UK & elsewhere.

5.4 Cladistics

IB Biology 5.4 Slides: Cladistics from Jacob Cedarbaum

IB 5.4 – Cladograms, a 15m video from Dan Rott.

Paul Andersen (from Bozeman High) discusses Phylogenetics and then shows you how to construct a Cladogram from a group of organisms using shared characteristics.

A fantastic animated tutorial from McGraw Hill Education on Phylogenetic trees.

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.


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