Teaching evolutionary theory is foundational for all biological sciences and a key aspect of overall science literacy. The conceptual framework for understanding evolution relies on thinking clearly about evolutionary trees (phylogenetics) and how geological history influences biological processes and diversity. Central to a student's comprehension … Webdifferent network algorithms (statistical parsimony, median-joining network, and minimum-spanning network) compared to a newly developed union of maximum parsimony trees approach using simulated data over four known tree topologies. They showed that maximum parsimony performed as well or better than the network
