Can a family tree of viruses solve a crime?
In short: This video explains how to interpret phylogenetic trees—the maps of evolutionary history—and applies those principles to a real-world criminal case involving the transmission of HIV.
The presenter demonstrates how to read evolutionary trees (also known as phylogenetic trees) to determine the relatedness between different organisms. By understanding these branching patterns, one can trace lineages and identify common ancestors.
To ground these concepts in reality, the video examines a landmark case: the first time an evolutionary tree was used in an American criminal court. The evidence centered on whether a doctor intentionally infected his ex-girlfriend with HIV, using viral evolution to track the path of transmission.
