It means, a animal reproduced another animal that was like it's parents.
Lions reproduced lions, Tigers - tigers, apes - apes, monkeys - monkeys, horses - horses, zebras - zebras, caterpillars - caterpillars, spiders -spiders, there was no change in any species from one "kind" to another "kind" of species. There were many "adaptations" that occurred "intra-species" but never to the point of evolving into a new species.
Are, for example, sheep and goats separate species or not?
