WebJun 12, 2024 · Cladistics refers to a biological classification system that involves the categorization of organisms based on shared traits. Organisms are typically grouped by how closely related they are and thus, cladistics can be used to trace ancestry back to shared common ancestors and the evolution of various characteristics. WebDec 24, 2024 · Orthologs, or orthologous genes, are genes in different species that originated by vertical descent from a single gene of the last common ancestor. For instance, the plant Flu regulatory protein is present both in Arabidopsis (multicellular higher plant) and Chlamydomonas (single cell green algae).
