LAST week, Richard Lewontin, a dialectical biologist, Marxist and activist died at the age of 92, just three days after Mary Jane, his wife of more than 70 years had passed away. He was one of the founders of modern biology that brought together three different disciplines -- statistics, molecular biology and evolutionary biology -- together what today marks the discipline. In doing so, he also battled not only crude racism masquerading as science, but also what science really is.
