WebMay 30, 2024 · It's very easy to generate a lot of different phylogenies. Using different methods, different models or approximation schemes, different genes or sequences from each species, or simply bootstrapping "new" samples from your existing dataset. WebA phylogenetic tree is a hypothesis of the evolutionary inheritance of genes across individual taxa. Trees have been used to summarize an organism’s pedigree, infer viral host-spillover events (Zhou et al., 2024), and determine if the red panda is a bear or a raccoon (Slattery & O’Brien, 1995)
WebPhylogeny helps scientists organize species or other groups in ways that represent our understanding of how they evolved from common ancestors.
