Answer:

Correct Answer: A

Solution:

Mutation Theory :-

  • Discovered by: Hugo de Vries

  • Description: Mutation theory proposes that new species arise from sudden, large-scale changes (mutations) in individuals. These mutations, according to de Vries, could be sudden jumps, rather than gradual changes proposed by Darwinian evolution.

Germ Plasm Theory:

  • Discovered by: August Weismann

  • Description: Weismann’s germ plasm theory states that heritable information is passed on only through germ cells (sperm and egg), not through somatic cells (cells of the body). This theory helped clarify how genetic information is transmitted across generations.

Philosophie Zoologique:

  • Written by: Jean-Baptiste Lamarck

  • Description: Lamarck’s work laid the groundwork for evolutionary theory before Darwin. He proposed that organisms evolve through the inheritance of acquired characteristics, suggesting that traits acquired during an organism’s lifetime could be passed on to offspring.

Origin of Species:

  • Written by: Charles Darwin

  • Description: Darwin’s seminal work, ““On the Origin of Species,”” introduced the theory of natural selection as the mechanism of evolution. Darwin proposed that species evolve over time through the process of natural selection, where individuals with favorable traits survive and reproduce.

Biogenetic Law (Biogenetic Principle):

  • Discovered by: Ernst Haeckel

  • Description: The biogenetic law, often summarized as ““ontogeny recapitulates phylogeny,”” suggests that the stages of development (ontogeny) of an organism reflect or recapitulate the evolutionary history (phylogeny) of its species. This idea has been influential in understanding developmental biology and evolution.
