Question

The mutation theory of evolution was proposed by

• A. Darwin
• B. Hugo de Vries
• C. Lamarck
• D. Huxley

Answer 1

The correct option is B Hugo de Vries

Hugo de Vries studied the inheritance of flower colour in Evening Primrose and proposed mutation theory that says that mutations are sudden, random, and inheritable and discontinuous variations which serve as raw material for evolution. Darwin proposed a theory of natural selection that explains the process of evolution by means of natural selection which in turn refers to an unequal ability of individuals to survive and reproduce based on suitability of their inherited characters to prevailing environmental conditions. Lamarck gave the theory of inheritance of acquired characters that explains evolution as the inheritance of acquired characters under influence of needs as posed as changing environmental conditions. The term new systematic was proposed by Huxley that emphasize three attributes of species; the phylogenetic relationship between different species, mutability, and ability of gradual modification. Thus, the correct answer is option B.
