WEISMANN Meaning and
Definition
-
Weismann refers to August Weismann, a German biologist and evolutionary theorist who lived from 1834 to 1914. He is known for his groundbreaking work on the theory of heredity, specifically the concept of the continuity of the germ-plasm and the distinction between somatic (body) cells and germ cells.
In Weismann's theories, the germ-plasm is the material responsible for transmitting hereditary traits from one generation to another. He proposed that there is a strict separation between the germ-plasm, found in the reproductive cells or germ cells, and the somatic cells that make up the rest of an organism's body. This theory of the continuity of germ-plasm implies that any changes or acquired characteristics in the somatic cells during an organism's lifetime do not affect the germ-plasm and therefore cannot be inherited.
Weismann's theories challenged the previous notions of the inheritance of acquired characteristics, which had been proposed by other scientists such as Jean-Baptiste Lamarck. Weismann argued that natural selection acts solely on genetic variations within the germ-plasm and that these variations, not acquired traits, are passed on to subsequent generations.
Today, Weismann's ideas have greatly influenced our understanding of genetics and the mechanisms of inheritance. His work laid the foundation for the study of molecular genetics and helped establish the field of evolutionary biology.
