It makes excellent sense and thank you for explaining your point if view so clearly. Evolutionists believe that cats originated from small rather generalised carnivores about 25 million years ago, and radiated across Asia and Europe. Remarkably these lines nearly all died out, modern cats being derived from only two ancestral lineages (basically big ones and little ones) and the handful of remaining big cat species all evolved quite recently, between 2 and 4 million years ago. These are the genus Panthera. There are a great many fossil cats, and one has to ask, as I have before, why God waited till relatively recently to create a couple of leopards and a couple of tigers (and couples of jaguars, lions and snow leopards), when he had already created so many other varieties of cat, only to let them go extinct.ryanbouma wrote:I'll explain my view again first. I'm old earth and I think God likely (not totally sure of the details) created pairs at a time. I obviously think some speciation occured. So back again to tigers. Perhaps he created a pair of tigers. Then Siberian tigers may have "evolved" from that family of tigers. But God would have put those tigers on the continents, not on the oceanic islands. Take your bats for example (and birds, and various plants). God created bats. They populate. A very small group makes it's way to an oceanic island. They then "evolve" into a species of bats not seen on the continents due to genetic and environmental pressure. Again, this fits the evolutionary model very well, but doesn't conflict with a day age or even young earth view. < snip > Just one more thing for clarification. I have no problem with God creating a tiger and a siberian tiger (I really don't know biology well), but I also don't have a problem with some varieties coming from one dominant species. But something like a leopard versus a tiger. I think they were individually created. I hope that makes sense.
Before we go on it would be worth considering the overall meaning of the Genesis story. It is the story of God's gradually preparing the world for the coming of people. My question is: which of the two interpretations of the method of creation best expresses this meaning? Evolution speaks of primitive life forms endlessly giving birth to new forms, increasing in diversity and number. Extinctions, by this reasoning, are part of the preparatory process, as life adapted increasing well to changing conditions, and new improved versions sprang from ancestral stock. Creation, by your interpretation, speaks mainly of destruction, of millions of species created and destroyed before man arrived. The previous species were not part of the preparation of the world, as they left no descendants, they were simply wasted efforts, whose only relevance to man was in the few fossils he finds of their existence. I am no theologian, but I wonder which of these two descriptions of the origins of the world as we see it today best seems to reflect God's purpose?
The definition of a species is that it cannot interbreed with another species, no matter how similar. So yes, we do know about these bats and they are sufficiently genetically distinct not to be able to breed with bats of other species. All organisms are genetically different, of course, but all those of the same species are sufficiently similar to be able to interbreed. All domestic dogs, for example, from the chihuahua to the mastiff, can interbreed, and the variety of breeds we see today is the result of humans selecting genetic traits for colour, size and shape, without interfering with reproductive possibility. If the world's populations of chihuahuas and mastiffs were to be kept strictly apart, with no interbreeding with intermediate varieties such as labradors and terriers, then it is likely that in a very short geological time (say half a million years) they would become separate species, and not even IVF would be possible. It is interesting to note that even after 30 000 years, domestic dogs can still interbreed with wolves, and are generally considered a sub-species rather than a distinct species, even after all this time. I don't know about bats, but birds can certainly be bred to produce distinct varieties, the domestic chicken and the domestic pigeon being particularly well documented examples.ryanbouma wrote:A quick question. Do you know if the bats you mentioned are able to reproduce with sister species of bats? It may be that's never been examined. It would be interesting to know. The bats may not want to either though. If they could not reproduce it would make for a stronger evolutionary case. If they could it would make the day age view no different really. I wonder how much bats and birds can be breed like dogs to produce varieties?
