Identification and classification f the earth's diverse species used to be based largely on observed structural characteristics. The discovery of the microscope and the improvement of its magnifying power allowed taxonomists to look into the internal structure down to the minute details of cell parts to arrive at classification schemes that better reflect natural relationships. Today, we can use the molecular data such as DNA sequences and protein structure similarities to determine which species evolved first and which species they eventually gave rise to. We can then arrange closely related species in sequence from the most primitive to the most advanced, and truly achieve a phylogenetic system of classifying organisms. This is what HARMONY IN DIVERSITY is all about.
