Who was an American evolutionary theorist and biologist who vocally supported the usage of the term "undulipodium"?
Lynn Margulis Lynn Margulis (born Lynn Petra Alexander; March 5, 1938 – November 22, 2011) was an American evolutionary theorist and biologist, science author, educator, and popularizer, and was the primary modern proponent for the significance of symbiosis in evolution. Historian Jan Sapp has said that "Lynn Margulis's name is as synonymous with symbiosis as Charles Darwin's is with evolution." In particular, Margulis transformed and fundamentally framed current understanding of the evolution of cells with nuclei – an event Ernst Mayr called "perhaps the most important and dramatic event in the history of life" – by proposing it to have been the result of symbiotic mergers of bacteria. Margulis was also the co-developer of the Gaia hypothesis with the British chemist James Lovelock, proposing that the Earth functions as a single self-regulating system, and was the principal defender and promulgator of the five kingdom classification of Robert Whittaker.
Stephen P. Hubbell Stephen P. Hubbell (born 17 February 1942) is an American ecologist on the faculty of the University of California, Los Angeles. He is author of the unified neutral theory of biodiversity and biogeography (UNTB), which seeks to explain the diversity and relative abundance of species in ecological communities. Hubbell is also a senior staff scientist at the Smithsonian Tropical Research Institute in Balboa, Panama. He is also well known for tropical forest studies. In 1980 he and Robin Foster of the Field Museum in Chicago, launched the first of the 50 hectare forest dynamics studies on Barro Colorado Island in Panama, and this plot became the flagship of a global network of large permanent forest dynamics plots, all following identical measurement protocols. This global network now has more than 40 plots in 22 tropical countries, and these plots contain more than 8000 tree species and 6 million individual trees that are tagged, mapped, and monitored long-term for growth, survival and recruitment. The Center for Tropical Forest Science coordinates research across global network of plots through the Smithsonian Tropical Research Institute. Since 2008 the program has expanded into the temperate zone, and is now known as the Smithsonian Institution Global Earth Observatory or SIGEO.
