intelligent design, right and wrong

Or it's a case of God controlling them & making them do evil.

Quetzal,Even though populations of Great Danes & Chihuahuas can't directly mate, gene flow between populations is possible. If a dog larger than a Chihuahua mates with a Chihuahua, a dog smaller than a Great Dane mates with a Great Danes. The offspring can potentially interbreed, "fusing" Chihahua & Great Dane genes (you know what I mean). Hence, gene flow is possible.Admittedly, the important part of your post was in the wild.Mark------------------

Nosyned,Good point, er, I just got called away from the computer, Quetz can you help? Quetzal,Am I wrong about Great Dames & Chihuahuas? Must all members of a population be able to be fertile with all other members in order for that population to be called a species? Thereby allowing ring species to be exactly that under the BSC? It seems an exception, though, since gene flow is possible between one end of the ring & the other.Mark------------------

Let me know if the above actually made any sense to anyone.

It did, but for clarification, are we saying that the phylogeographical breaks were once actually indicative of an actual geographical barrier to gene flow, now no longer present? ie one species expands its geographical range around both sides of a mountain range, by the time the two populations meet at the other side they are different enough to either have actually speciated, or differ enough that mate selection reduces gene flow across the zone?Thanks,Mark------------------
