How do molecular markers work to unlock the evolutionary history of organisms?

Explanation

The results of a molecular phylogenetic analysis are expressed in the form of a tree called phylogenetic tree. Different molecular markers like allozymes, mitoc ke allozymes, mitochondrial DNA, micro satellites, RFLP (Restriction Fragment Length Polymorphism), RAPD (Random amplified polymorphic DNA), AFLPs (Amplified Fragment Length Polymorphism), single nucleotide polymorphism-SNP, microchips or arrays are used in analysis.
Uses of molecular taxonomy,
(i) Molecular taxonomy helps in establishing the relationship of different plant groups at DNA level.
(ii) It unlocks the treasure chest of information on evolutionary history of organisms.
