Propolis Cognitive Error Autopsy

Official Correct Choice:
Option A: Lamarck
Concept:

Early evolutionary thought included the idea that traits developed during a single lifetime could be transmitted to the next generation.

Solution:

  • The French biologist Jean-Baptiste Lamarck proposed the first cohesive theory of evolution in 1809.
  • His primary mechanism was the inheritance of acquired characteristics, which suggested that modifications acquired by an organism through use or disuse of a body part could be directly passed on to its offspring (e.g., giraffes stretching their necks).
  • Modern genetics has since proven this mechanism incorrect.


Why other options are incorrect:

  • Darwin: Proposed natural selection, acting on inherited variations, not acquired somatic traits.
  • Malthus: An economist who wrote about population growth limits.
