The biogenetic law of recapitulation dictates that the trajectory of human development flows:
Show answer Hide answer
Answer: A. Extreme to middle
Explanation
The biogenetic law states that the developmental trajectory of an organism reflects evolutionary stages. Ontogeny recapitulates phylogeny, connecting individual growth patterns to broader evolutionary developmental histories. This historical biological framework guided early theories regarding human physical and psychological maturation. Ernst Haeckel formulated the biogenetic law in the nineteenth century to explain vertebrate embryonic development. Evolutionary biology explores how species develop and adapt over generations through natural selection. Developmental psychology historically drew parallels between child development and evolutionary anthropology.
While largely discredited as a strict biological rule, it influenced early developmental milestones research. Historians of science study these concepts to understand the evolution of developmental psychological theories. Modern developmental science relies on empirical genetics rather than recapitulation theories to explain maturation. Option B suggests middle to extreme trajectories, which does not reflect the established biogenetic law. Option C proposes middle to outer development, failing to describe ontogenetic recapitulation principles. Option D includes all of the above, which is incorrect because only the initial statement aligns with historical law.
