Which scientist proposed the theory of "Continuity of Germplasm"?

• A. Weismann
• B. Mendel
• C. Darwin
• D. Goldschmidt

Answer: (A)

The theory of "Continuity of Germplasm" was proposed by August Weismann, who was an influential biologist in the late 19th century. This theory emphasizes that the germ cells (which are gametes) responsible for reproduction are distinct from the somatic cells (the body cells) and that the genetic material is passed unchanged from generation to generation through the germline. Weismann rejected the notion of the inheritance of acquired characteristics, a view held by Darwin, and instead argued that only hereditary traits that are present in the germ cells are transmitted to offspring. His work laid a foundation for the field of genetics, influencing our understanding of heredity and the biological continuity across generations. The other scientists listed contributed significantly to biological sciences, but their theories and findings are distinct from Weismann's ideas about germplasm. Mendel is known for his work on the principles of genetic inheritance, and Darwin is famed for his theories on evolution through natural selection. Goldschmidt contributed to genetics but in different contexts, making Weismann's association with the continuity of germplasm uniquely significant in the study of heredity.
