- 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".
