ORIGIN OF LIFE

Which statement about evolution is NOT true?

Goal oriented reflects key principle in quiz on section b pyqs- origin of life, where evolutionary mechanisms shape genetic variation and adaptation. In this context, Goal oriented aligns with experimental and theoretical evidence from population genetics, behavioral ecology and molecular phylogeny. Textbooks like Campbell Biology, Futuyma Evolution and Hartl Principles illustrate supporting data. Understanding why Goal oriented fits helps integrate natural selection, environment.

Theory of evolution

Lamarck referred his theory of evolution as

Lamarck proposed transformism emphasizing use and disuse and inheritance of acquired characters as mechanism for adaptation, such as giraffe stretching neck. Though germplasm theory and Weismann's mouse tail experiments refuted inheritance of acquired traits, Lamarck was first to propose formal evolutionary theory. Neo-Lamarckism later attempted revival. Understanding his ideas clarifies historical development from goal-directed evolution to natural selection. Therefore Transformism relates directly to Lamarckian principles and their eventual rejection. This concept integrates genetics, ecology and molecular evidence, frequently tested in NEET, GATE and CSIR-NET, highlighting links between genotype, phenotype and environment.

Ref: Campbell Biology, 12th ed., Chapter 22: Descent with Modification.
