Which of the following theories representing the Lamarckian theory of evolution is false?

Correct answer: B. Theory of genetic changes

  • A. Inheritance of acquired characteristics
  • B. Theory of genetic changes
  • C. Both A and B
  • D. None of these

Explanation

Lamarck's theory of evolution is based on the idea of inheritance of acquired characteristics, where traits acquired or lost during an organism's lifetime can be passed to the next generation. Option B is correct because the theory of genetic changes was not part of Lamarck's proposition. This concept emerged later with the discovery of genetics. Option A is incorrect, as it aligns with Lamarck's ideas. Option C is incorrect because it incorrectly combines both true and false statements. Option D is wrong, as it suggests no statement is false, while option B is indeed false concerning Lamarck's theory.

About Evolution

Evolution describes heritable change in populations over generations through variation, natural selection and adaptation. Lamarckism explains inheritance of acquired characteristics, while Darwinism explains selection of favourable inherited variations; these historical explanations must not be confused with the modern genetic account of evolutionary change.
