Question

Which English scientist worked on the origin of life and finally settled in India?
A. A. I. Oparin
B. Louis Pasteur
C. J.B.S. Haldane
D. Archbishop Ussher

Answer 1

Hint: He was a scientist who was born in England but later migrated to India in July 1957 and finally settled in Bhubaneshwar, Orissa. He was known for his work on population genetics and evolution.

Complete answer: John Burdon Sanderson Haldane was a scientist who is known for his work in the field of physiology, genetics, evolutionary biology, and mathematics. John Burdon used new statistics methods in biology and he was one of the founders of Neo-Darwinism. He worked on the origin of life and after that, he settled in India. As mentioned above he was settled in the city of Bhuvneshwar which has been known for temples and referred to as “ Temple city of India’’.He made innovative contributions to biostatistics and statistics. He worked with Oparin who was a Russian scientist and gave the same views about the origin of life. They proposed a chemical theory which stated that life originated upon the earth from non-living matter or inanimate objects or given that Life began at deep-sea vents.
The “primordial soup theory” was introduced in 1929 as a result of Haldane’s article on abiogenesis, which later became the foundation of the chemical origin of life. He also established human gene maps for haemophilia and colour blindness on the X chromosome and codified Haldane's rule on sterility in the heterogametic sex of hybrids in species.
Hence, the correct answer is option C.

Note: In 1957, Haldane shifted to Orissa and headed the government genetics and biometry laboratory. He was a British geneticist, biometrician, and physiologist. He developed the quantitative theory of evolution.
