Minerals are classified by chemical formula, composition, physical properties, optical properties, and special properties. The Dana Classification System is a chemical classification for minerals, and the Strunz Classification System (chemical-structural) are two systems designed for mineral classification.

It is true that scientists determine evolutionary relationships by looking at breeding behavior, geological distribution, and structural similarities between organisms. Scientists can use other criteria to determine evolutionary relationships.

Melanin is a pigment produced in specialized cells called melanocytes. The classification of melanin falls under the molecular level of structural organization as it is made up of complex molecules that impart color to skin, hair, and eyes.
The grouping is based on structural and physiological similarities, on evolutionary relationships.
