This powerpoint presentation covers Topic 5.4 (Evolution) in the IB Biology curriculum. Each slide is labelled with the specific learning objective and animation/video links are provided in the slide notes.
The slides are formatted to print well for handouts or revision and I can provide a pdf version upon request.
As always, please let me know if you have any suggestions for improvements. These are always a work in progress!
**IB Biology Learning Objectives:
5.4.1 – Define evolution
5.4.2 – Outline the evidence for evolution provided by the fossil record, selective breeding of domesticated animals and homologous structures.
5.4.3 – State that populations tend to produce more offspring than the environment can support.
5.4.4 – Explain that the consequence of the potential overproduction of offspring is a struggle for survival.
5.4.5 – State how the members of a species show variation.
5.4.6 – Explain how sexual reproduction promotes variation in a species.
5.4.7 – Explain how natural selection leads to evolution
5.4.8 – Explain two examples of evolution in response to environmental change; one must be antibiotic resistance in bacteria.
