Basic Evolution

Peppered moth example shows:

Directional selection reflects key principle in quiz on section a solved pyqs, where evolutionary mechanisms shape genetic variation and adaptation. In this context, Directional selection 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 Directional selection fits helps integrate natural selection, environment.

NATURAL SELECTION

Industrial melanism is an example of

Industrial melanism in peppered moth Biston betularia shows directional selection favoring dark morph in soot-polluted forests due to improved camouflage from bird predation. Kettlewell's experiments measured selection coefficients. With clean air acts, light morph recovered. This classic example demonstrates natural selection acting on existing variation in response to human-induced environmental change. Therefore it exemplifies Directional selection driving rapid adaptive shift. This concept integrates genetics, ecology and molecular evidence, frequently tested in NEET, GATE and CSIR-NET, highlighting links between genotype, phenotype and environment.
