J.B.S. Haldane

Geneticist and evolutionary biologist (1892-1964)

J.B.S. Haldane introduced the primordial soup theory in 1929, establishing a framework for understanding the chemical origins of life. A versatile scientist born in Oxford, he applied rigorous statistical methods to biology, eventually becoming a foundational figure in neo-Darwinism and the development of population genetics through his extensive academic and research career.

Academic Foundation and Early Research

Educated at the Dragon School, Eton College, and the University of Oxford, Haldane was largely self-taught in biological sciences. He balanced a formal background in classics and mathematics with early physiological experiments alongside his father. His research expanded into human gene mapping, specifically identifying markers for haemophilia and colour blindness on the X chromosome.

Contributions to Evolutionary Theory

Haldane served as a professor at University College London, where he codified Haldane's rule regarding the sterility of heterogametic hybrid sexes. He proposed that sickle-cell disease provides immunity to malaria and introduced concepts such as the hydrogen economy, in vitro fertilisation, and the darwin as a unit of evolution. In 1957, he articulated Haldane's dilemma concerning the speed of natural selection.

Military Service and Final Years

During World War I, Haldane served as a captain in the British Army. His career eventually took him away from England to India in 1956. He became a naturalised Indian citizen in 1961, continuing his scientific work at the Indian Statistical Institute in Bhubaneswar until his death in 1964. He willed his body to medical research.
