The concept of evolution was first presented by which of the following scientists?
Correct answer: A. Lamarck
- A. Lamarck
- B. Aristotle
- C. Wallace
- D. Darwin
Explanation
Jean Baptiste Lamarck was one of the first scientists to propose a coherent theory of evolution, known as Lamarckism, which posited that traits acquired during an organism's lifetime could be passed on to its offspring. This was a foundational concept that preceded the more widely accepted theories of Darwin and Wallace. Aristotle, on the other hand, did not formulate a theory of evolution, focusing instead on classification. Wallace and Darwin both contributed significant theories to the field, but their ideas came after Lamarck's initial proposal.

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.
