Richard Levins

Richard Levins (June 1, 1930 – January 19, 2016)[3] was a Marxist biologist, a population geneticist, biomathematician, mathematical ecologist, and philosopher of science[4][5][6] who 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 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.[citation needed] 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 author's notes (not published until 1939) for Das Kapital. With the evolutionary geneticist Richard Lewontin, 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.[7]

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.

Biography

edit

Richard Levins was of Ukrainian Jewish heritage and was born on June 1, 1930, in Brooklyn, New York.[8] 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,[9] Ricardo,[1] and Alejandro[2] - 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[10][11] (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[12] and head of the Human Ecology program[13][14] in the Department of Global Health and Population of the Harvard School of Public Health.[15] 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).[16]

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. As a member of the OXFAM-America Board of Directors and former chair of their subcommittee on Latin America and the Caribbean, Richard Levins worked from a critique of the industrial-commercial pathway of development and promoted alternative development pathways which focused attention upon (a) economic viability with (b) population equity, (c) ecological and social sustainability, and (d) empowerment of the dispossessed.

When his wife Rosario died in 2011, his daughter Aurora moved in with her father in his Cambridge, Massachusetts home.

One of Levins's grandchildren is Minneapolis-based hip hop artist Manny Phesto.[17][18]

Levins died in Cambridge, Massachusetts, on January 19, 2016.[19][20]

A species of lizard, Sphaerodactylus levinsi, is named in his honor.[21]

Evolution in changing environments

A Map of the Loop Current

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.

Metapopulation theory

edit
 

The term metapopulation was coined by Levins in 1969 to describe a "population of populations".[22] Populations inhabit a landscape of suitable habitat patches, each capable of hosting a local sub-population. Local populations may become 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.[23][24]

Quotations

edit
  • "The world is stranger than we can imagine and surprises are inevitable in science. Thus we found, for example, that pesticides increase pests, antibiotics can create pathogens, agricultural development creates hunger, and flood control leads to flooding. But some of these surprises could have been avoided if the problems had been posed big enough to accommodate solutions in the context of the whole." - Dr. Richard Levins
