Description

How can DNA reveal the story of evolution and survival in the Leadbeater possum?

In Exploring Evolution designed for VCE Biology Unit 4, students investigate genetic diversity and evolutionary relationships in local Leadbeater possum populations in the Yarra Ranges region. In partnership with Healesville Sanctuary, students explore how molecular evidence can uncover the evolutionary history and survival strategies of species.

Students will use micropipettes and gel electrophoresis to analyse DNA samples, identifying genetic variation within and between populations. They will explore molecular and structural homology, and use this data to construct and interpret phylogenetic trees. These activities develop core scientific skills while connecting evolutionary biology to local conservation efforts. This session aligns with VCE Biology Unit 4, Outcome 2, supporting potential School Assessed Coursework (SACs) through practical evidence collection, comparative analysis, and data interpretation. It provides a rich opportunity to explore the mechanisms of evolution, the consequences of changing allele frequencies, and the value of biodiversity for species survival.
