Which is NOT a type of evolution?

Mutation rate reflects key principle in quiz on type of evolution+pyqs, where evolutionary mechanisms shape genetic variation and adaptation. In this context, Mutation rate 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 Mutation rate fits helps integrate natural selection, environment.

TYPE OF EVOLUTION

Convergent evolution is driven mainly by:

Convergent evolution occurs when unrelated lineages independently evolve similar traits due to similar environmental pressures, such as wings in birds and bats or streamlined bodies in dolphins and sharks, resulting in analogous structures with similar function but different ancestry. It reflects adaptation to common niche, not common descent, and can mislead phylogeny as homoplasy. Divergent evolution produces homologous structures. Hence Similar selection pressures results from convergence producing analogy. This concept integrates genetics, ecology and molecular evidence, frequently tested in NEET, GATE and CSIR-NET, highlighting links between genotype, phenotype and environment.

Parallel evolution differs from convergent evolution because it involves:

Convergent evolution occurs when unrelated lineages independently evolve similar traits due to similar environmental pressures, such as wings in birds and bats or streamlined bodies in dolphins and sharks, resulting in analogous structures with similar function but different ancestry. It reflects adaptation to common niche, not common descent, and can mislead phylogeny as homoplasy. Divergent evolution produces homologous structures. Hence Related species results from convergence producing analogy.

Neutral theory of evolution was proposed by:

Molecular evolution studies changes in DNA, RNA and proteins over time. Neutral theory by Kimura proposes most molecular substitutions are neutral and fixed by drift at rate equal to mutation rate, explaining molecular clock constancy where synonymous mutations accumulate steadily. Mitochondrial DNA maternally inherited and pseudogenes evolving faster due to lack of constraint provide markers for phylogeny. Purifying selection removes deleterious variants. Therefore Kimura illustrates principle of molecular evolution and neutral processes. This concept integrates genetics, ecology and molecular evidence, frequently tested in NEET, GATE and CSIR-NET, highlighting links between genotype, phenotype and environment.

Adaptive radiation is a feature of:

Adaptive radiation describes rapid diversification of single ancestor into many forms exploiting different ecological niches, driven by ecological opportunity, such as Darwin's finches evolving varied beaks for seeds, insects and cactus, or cichlids in African lakes. It involves divergent evolution, morphological innovation and often occurs after colonization or mass extinction. Homologous structures reflect common ancestry. Classic example illustrates Macroevolution as diversification from common ancestor into distinct niches. This concept integrates genetics, ecology and molecular evidence, frequently tested in NEET, GATE and CSIR-NET, highlighting links between genotype, phenotype and environment.
