Who was an American evolutionary theorist and biologist who vocally supported the usage of the term "undulipodium"?
Undulipodium An undulipodium (a Greek word meaning "swinging foot") or a 9+2 organelle is a motile filamentous extracellular projection of eukaryotic cells. It is basically synonymous to flagella and cilia of the prokaryotic cells. In fact the name was coined to differentiate from the analogous structures present in prokaryotic cells. It is structurally a complex of microtubules along with motor proteins. The usage of the term is most vocally supported by Lynn Margulis, especially in support of her endosymbiotic theory. The eukaryotic cilia are structurally identical to eukaryotic flagella, although distinctions are sometimes made according to function and/or length.
