Basic Evolution

Biogeny explains:

Origin of life from life reflects key principle in quiz on section b solved pyqs, where evolutionary mechanisms shape genetic variation and adaptation. In this context, Origin of life from life 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 Origin of life from life 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,

Chemogeny & biogeny

Biogeny refers to

After organic monomers accumulated, their organization into self-maintaining systems marks transition to life. Biogeny describes evolution of protobionts, protocells and true prokaryotic cells capable of metabolism, growth and imperfect replication subject to selection. It follows chemogeny and encompasses origin of genetic material, membranes and autotrophy. Unlike purely chemical steps, biogeny involves biological properties like heredity. Hence Biological evolution captures this later phase where molecular evolution becomes Darwinian. This concept integrates genetics, ecology and molecular evidence, frequently tested in NEET, GATE and CSIR-NET, highlighting links between genotype, phenotype and environment.
