Numismatics is the study of the physical embodiment of various payment media (i.e. currencies). <em>The study of numismatics as it applies to coins is often in the research of the production and use of the coins to determine their rarity.</em>
Systematics, or Taxonomy, is the study of the kinds of organisms of the past and living today, and of the relationships among these organisms. <em>Systematists collect and study the variety of plants and animals and group them according to patterns of variation.</em>
<em>Speciation is an evolutionary process by which a new species comes into being</em>. A<em> species is a group of organisms that can reproduce with one another to produce fertile offspring and is reproductively isolated from other organisms.</em>
