This 23-slide Powerpoint presentation covers 'Topic 5.1 - Evidence for Evolution' in the 2016 IB Biology curriculum. Each slide includes the specific learning objective as well as key vocabulary that students should note. The topic has been divided into two sections:
A - Evidence
B - Speciation
The presentation itself contains minimal information as it is intended to be used with teacher guidance. They are also formatted to be visually pleasing and to print well for handouts or revision. Please see the preview file for an idea of the slide aesthetic and level of detail.
As always, please let me know if you have any suggestions for improvements. These are always a work in progress!
U1: Evolution occurs when heritable characteristics of a species change.
U2: The fossil record provides evidence for evolution.
U3: Selective breeding of domesticated animals shows that artificial selection can cause evolution.
U4: Evolution of homologous structures by adaptive radiation explains similarities in structure when there are differences in function.
U5: Populations of a species can gradually diverge into separate species by evolution.
U6: Continuous variation across the geographical range of related populations matches the concept of gradual divergence.
A1: Development of melanistic insects in polluted areas.
A2: Comparison of the pentadactyl limb of mammals, birds, amphibians and reptiles with different methods of locomotion.
