 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".
