You want some examples of evolutionists who are Marxists?
Richard Levins and Richard Lewontin are evolutionary biologists. They view themselves as Marxist revolutionaries. How about Jonathan Beckwith , professor of microbiology at Harvard. At MIT we have Jonathan King and Noam Chomsky. Stephen Gould admits to his Marxism and actually lauds the way science is informed by his beliefs. Many of these people are members of a radical organization called "Science for the People," which grew out of the campus rebellions and anti-war protests of the 60's.
Richard Levins and Lewontin stated "Scientists, like other intellectuals, come to their work with a worldview, a set of preconceptions that provides the framework for their analysis of the world."
That's just for starters..........There's also Dawkins...
