AI overview
Phylogenetics is the study of how different living organisms are related to each other through their evolutionary history. It matters because it helps scientists understand how traits like venom evolved across different species and reveals the connections between all life on Earth.

In biology, phylogenetics () is the study of the evolutionary history of life using observable characteristics of organisms (or genes), which is known as phylogenetic inference. It infers the relationship among organisms based on empirical data and observed heritable traits of DNA sequences, protein amino acid sequences, and morphology. The results are a phylogenetic tree—a diagram depicting the hypothetical relationships among the organisms, reflecting their inferred evolutionary history.
