Loss of limbs in snakes is best explained by:
Reduced fitness of limbs reflects key principle in quiz on section a solved pyqs, where evolutionary mechanisms shape genetic variation and adaptation. In this context, Reduced fitness of limbs 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 Reduced fitness of limbs fits helps integrate natural selection, drift and species concepts essential for NEET, CSIR-NET and GATE examinations. This concept integrates genetics, ecology and molecular evidence, frequently tested in NEET, GATE and CSIR-NET, highlighting links between
