- What is inbreeding and what is outbreeding?
- What is natural selection, including disruptive slection, stabilising selection, directional selection and sexual selection?
- What is a phylogenetic treee and what is the role of molecular biology?
- What are genetic mutations, including gene mutations, chromosomal mutations and ploidy - and what are their roles in evolution?
- What is speciation and how do reproductive isolating mechanisms function?
- What is allopatric speciation and what is sympatric speciation?
- What is instant speciation / polyploidy?
- What can we determine from fossil evidence?
- What evidence of evolution can we attain from genetic analysis?
- What evidence of evolution can we attain from biogeographical factors?
- What is gradualism and punctuated equilibrium; how do these rates of evolution differ?
- What is divergent evolution and adaptive radiation?
- What is convergent evolution?
- What are the differences in comparative anatomy between homologous and analogous structures?
- What is co-evolution and what species can we observe to have co-evolved?
How you'll learn
People learn in different ways. Now we'll describe some of the ways you can learn and interact with the materials in this course.
Self-paced learning – the material is set up so you can learn at your own pace. So, although there are 'suggested' times for each page, they're just a guideline. Plan your learning to suit you.
Practice activities – throughout this course there are short activities. These activities are for you, not for someone to mark them. These activities give you a great chance to practice what you've learned and compare your answer to the model feedback. Look at the feedback carefully to see if you have missed out any aspects from your answer.
Submitting photos – sometimes people find it easier to scribble down a diagram or show their working with pen and paper. No problem! You can still store all your working and diagrams with the activity. That way you'll be able to refer back to your answers when you're revising. Simply take a photo of your work and upload it with the relevant activity.
