Polyphyletic
/ˌpɒl·ɪ·faɪˈlɛt·ɪk/adjective
ELI5 Mode🧒
Polyphyletic refers to a group of organisms that descend from more than one distinct ancestral lineage, meaning they don't share a single common ancestor. This concept is pivotal in modern evolutionary biology to highlight misleading classifications based on convergent traits, ensuring that taxonomic groups reflect true genetic relationships rather than superficial similarities.

The recognition of polyphyletic groups has upended traditional classifications, such as discovering that electric eels aren't true eels but are more closely related to knifefish, which has influenced how we study bioelectricity and animal adaptations in over 200 species worldwide.
