Now, think of each link as a population of a given species (like the famous salamander in california). Every population can interbreed with the ne ...[text shortened]... there are such genetic differences between more than just two populations to call it a "chain".

Originally posted by RJHindsI believe you're not paying attention. If two populations of salamanders (for instance) can't or won't reproduce because the genetic differences between them are too big (ring species or not), you have observed speciation. They can only drift further apart from there on, since they won't exchange genetic material (no gene flow between them).

Kind? I don't know what a kind is. That has yet to be defined scientifically so that we can determine if "kind" is a useful taxon.

Originally posted by C HessKinds are those different creatures originally made by God to reproduce after there own kind. A creature that can no longer reproduce does not make it a different kind than its mother. It just means that it has a defect that makes it unable to reproduce after its own kind.

You're saying that living things only reproduce within their own kind. If we have two populations of salamanders, and within those populations the salamanders reproduce just fine, then clearly they're not defective. But, when individuals from one population meet individuals from the other, they can't or won't reproduce. That, by your definition, means they're no longer the same kind, as they're only supposed to reproduce within their own kinds.
This all means that you've now witnessed macro-evolution. Welcome to the evolution camp. The drinks are over there. Cheers! 😏
Originally posted by C HessNo. You are not understanding me. It is true that I believe living things only reproduce their own kind. A dog will not reproduce a cat because they are different kinds or species.
HA! Got you!

If a Chihuahua does not reproduce with a Great Dane it does not mean they are different species or kinds of animals, but only different breeds of dog. They are still dogs of the canine species or kind of animals. But if a female Great Dane is unable to reproduce with a male Great Dane, then there is probably a defect in the reproductive system, but they are still dogs of the canine kind or species of animals.
It is the same way with the salamanders. They do not cease to be salamanders because they fail to reproduce. However, salamanders and frogs are different species or kinds because a salamander will never reproduce with a frog.
Does that help you understand?

Where in the Bible does it say dogs and cats were created separately? How do you know they aren't both descended from the same original creation?
