1) kind, sometimes a species (usually of animals)
++++
Groups of living organisms belong in the same created |kind| if they have descended from the same ancestral gene pool. This does not preclude new species because this represents a partitioning of the original gene pool. Information is lost or conserved not gained. A new species could arise when a population is isolated and inbreeding occurs. By this definition a new species is not a new |kind| but a further partitioning of an existing |kind|.
