What are Cladograms?
This video will introduce cladograms for QCE Biology.
3.1.2 – Classification Processes
- Interpret cladograms to infer the evolutionary relatedness between groups of organisms
- Analyse data from molecular sequences to infer species evolutionary relatedness
- Recognise the need for multiple definitions of species
- Identify one example of an interspecific hybrid that does not produce fertile offspring (e.g. mule, Equus mulus)
What are Cladograms and What do they Show?
This video introduces cladograms.
How to Make a Cladogram?
This video goes through cladograms in a little more depth and shows how to make one.
This video goes through some concepts that define a species.
This video goes through interspecific (between species) and intraspecific interactions (within species).
