Why are molecular tools used now to study taxonomy ?

Explanation

DNA hybridization (measures the degree of genetic similarity between pools of DNA sequences DNA fingerprinting to identify an individual from a sample of DNA by looking at unique patterns in their DNA, Restriction Fragment Length Polymorphisms (RFLP) analysis (difference in homologous DNA sequences that can be detected by the presence of fragments of different lengths after digestion of the DNA samples), and Polymerase Chain Reaction (PCR) sequencing (to amplify a specific gene, or portion of gene) are used as taxonomical tools
