Propolis Cognitive Error Autopsy

Official Correct Choice:
Option A: Jean Baptist Lamarck
Concept:

Before Mendelian genetics were understood, scientists formulated various hypotheses regarding how traits were inherited.

Solution:

  • The French naturalist Jean-Baptiste Lamarck presented his theory of evolution in 1809.
  • His central premise was the inheritance of acquired characteristics, arguing that traits modified through use or disuse during an organism's lifetime could be directly passed to its offspring.


Why other options are incorrect:

  • Darwin / Wallace: Co-discoverers of Natural Selection, which operates on pre-existing, inheritable variations, not lifetime acquisitions.
  • Malthus: Wrote an essay on population growth that heavily influenced Darwin.
