Question

Quizplus · Accepted Answer

The biogenetic law, also known as the recapitulation theory, proposes that the development of an individual organism (ontogeny) follows the evolutionary history of its species (phylogeny). This means that the stages of embryonic development and growth in an organism can be seen as reflecting the stages of evolutionary development that its ancestors went through. Therefore, the best answer is B, which refers to the development of an organism from conception. Choices A, C, and D do not match the definition of biogenetic law.
