|Dr. Richard Levins, teaching|
Richard "Dick" Levins (June 1, 1930 – January 19, 2016) was an ecologist, a population geneticist, biomathematician, mathematical ecologist, and philosopher of science who had researched diversity in human populations. Until his death, Levins was a university professor at the Harvard T.H. Chan School of Public Health and a long-time political activist. He was best known for his work on evolution and complexity in changing environments and on metapopulations.
Levins' writing and speaking is extremely condensed. This, combined with his Marxism, has made his analyses less well-known than those of some other ecologists and evolutionists who were adept at popularization. One story of his Chicago years is that graduate students had to attend Levins' courses three times: the first time to acclimate themselves to the speed of his delivery and the difficulty of his mathematics; the second to get the basic ideas down; and the third to pick up the subtleties and profundities.
Levins also had written on philosophical issues in biology and modelling. One of his influential articles is "The Strategy of Model Building in Population Biology". He has influenced a number of contemporary philosophers of biology. Levins often boasted publicly that he was a 'fourth generation Marxist' and often had said that the methodology in his Evolution in Changing Environments was based upon the introduction to Marx's Grundrisse, the rough draft of Das Kapital. With the evolutionary geneticist Richard Lewontin (1929–), Levins had written a number of articles on methodology, philosophy, and social implications of biology. Many of these are collected in The Dialectical Biologist. In 2007, the duo published a second thematic collection of essays titled Biology Under the Influence: Dialectical Essays on Ecology, Agriculture, and Health.
Also with Lewontin, Levins had co-authored a number of satirical articles criticizing sociobiology, systems modeling in ecology, and other topics under the pseudonym Isadore Nabi. Levins and Lewontin managed to place a ridiculous biography of Nabi and his achievements in American Men of Science, thereby showing how little editorial care and fact-checking work went on in that respected reference work.
Richard Levins was of Ukrainian Jewish heritage and was born on June 1, 1930, in Brooklyn, New York. He recorded reminiscences of his politically and scientifically precocious childhood in an article in Red Diapers. He reportedly had read Paul de Kruif's Microbe Hunters (1926) at age 8 (in 1938) and his first of Charles Darwin's books at age 12 (in 1942). At the age of 10, Levins had been inspired by the essays of the Marxist biological polymath J. B. S. Haldane, whom Levins considers to be the equal of Albert Einstein in scientific importance.
Levins studied agriculture and mathematics at Cornell. He married Puerto Rican writer Rosario Morales in 1950. Blacklisted on his graduation from Cornell, he and Rosario moved to Puerto Rico, where they farmed and did rural organizing. They returned to New York in 1956, where he earned his PhD at Columbia University (awarded 1965). Levins taught at the University of Puerto Rico from 1961 to 1967 and was a prominent member of the Puerto Rican independence movement. He visited Cuba for the first time in 1964, beginning a lifelong scientific and political collaboration with Cuban biologists. His active participation in the independence and anti-war movements in Puerto Rico led to his being denied tenure at the University of Puerto Rico, and in 1967 he and Rosario and their three children - Aurora, Ricardo, and Alejandro - moved to Chicago, where he taught at the University of Chicago and constantly interacted with Lewontin. Both Richard and Rosario later moved to Harvard with the sponsorship of E. O. Wilson, with whom they had later disputes over sociobiology. Levins was elected member of the US National Academy of Sciences but resigned because of the Academy's role in advising the US military during the war. He had been a member of the US and Puerto Rican Communist Parties, the Movimiento Pro Independencia (the Independence movement in Puerto Rico), and the Puerto Rican Socialist Party, and he was on an FBI surveillance list.
Until his death, Levins was John Rock Professor of Population Sciences and head of the Human Ecology program in the Department of Global Health and Population of the Harvard School of Public Health. In the early 1990s, Levins and others formed the Harvard Working Group on New and Resurgent Diseases. Their work showed that alarming new infections had sprung from changes in the environment, either natural or caused by humans (Wilson et al. 1994). During his final two decades, Levins had concentrated on application of ecology to agriculture, particularly in the economically less-well-developed nations of this planet.
Evolution in changing environments
Prior to Levins' work, population genetics had assumed the environment to be constant, while mathematical ecology assumed the genetic makeup of the species involved to be constant. Levins modelled the situation in which evolution is taking place while the environment changes. One of the surprising consequences of his model is that selection need not maximize adaptation, and that species can select themselves to extinction. He encapsulated his major early results in Evolution in Changing Environments, a book based on lectures he delivered in Cuba in the early 1960s. Levins made extensive use of mathematics, some of which he invented himself, although it had been previously developed in other areas of pure mathematics or economics without his awareness of it. For instance, Levins makes extensive use of convex set theory for fitness sets, (resembling the economic formulations of J. R. Hicks) and extends Sewall Wright's path analysis to the analysis of causal feedback loops.
The term metapopulation was coined by Levins in 1969 to describe a "population of populations". Populations inhabit a landscape of suitable habitat patches, each capable of hosting a local sub-population. Local populations may go extinct and be subsequently recolonized by immigration from patches; the fate of such a system of local populations (i.e., the metapopulation) depends on the balance between extinctions and colonizations. Levins introduced a model consisting of a single differential equation, nowadays known as the Levins model, to describe the dynamics of average patch occupancy in such systems. Metapopulation theory has since become an important area of spatial ecology, with applications in conservation biology, population management, and pest control.
