Chris W:
I have not seen your answer to Buffalo’s question. Does deviation mean the same thing as evolution to a new and higher life form? And does DNA increase or decrease in complexity in the “speciation” observed in your link?
They were examples of speciation not deviation.
Evolution merely predicts that organisms will speciate if different segments of a population are isolated from each other. So a “new” species is produced. As for a “higher” species what do you mean by that? All evolution predicts is that the new species will be better able to survive in the altered environment than the previous one not that it is necessarily a “better” or more complex species.
In some examples the DNA may have gotten more “complex” but in others it may have stayed the same or gotten simpler. Sequencing a genome is a fairly arduous task and has only been accomplished recently for a limited number of species. I doubt a that data was included in the results but since not only because sequencing wasn’t available at the time of many of the experiments but also the differences between species have historically been establish without such data.
There are plenty of examples of species loosing traits as they evolved. Snakes and whales have lost their limbs for example.
Chris W:
You have also not asnwered my question: Where do you percieve a “god of the gaps” in my position?
I have answered this question, directly to you. And I asked you how you resolve the conflicts I perceive between evolution and Catholicism. Once again you have not answerded the question, other than to say you don’t see the conflict.
Well, forgive me if I’m misunderstanding your posts but I see two themes in your objections both dealing with human exceptionalism but only one of which is a potential “god of the gaps” problem
(1) as you put it “……the fact that humans have the ability to reason, free will, and a conscience, while no other living thing on earth has those attributes?”
and (2) the existence of the soul and the reconciliation of evolution with the Church’s teaching regarding Original sin, Adam & Eve, and the creation of Eve.
Number (1) is potentially problematic. Items such as free will don’t leave fossils in the classic sense but as you pointed out, behaviors can be observed and studied. There are fields such as evolutionary psychology that specialize in answering just those questions. They are relatively new fields but they do produce some interesting results. I really don’t follow them too much so I don’t know what the latest and greatest is but I have seen work that describes human behavior in adaptive terms.
My “god of the gaps” comment came along because if you’re objecting to evolution for those reasons what are you going to do if someone comes along with a good working theory for the evolution of reason?
To me that wouldn’t diminish God in the least; evolution is just the tool He used to mold the clay.
As for number (2) well you probably got me there. I’m and engineer not a theologian.
My personal interpretation is that when the first almost-humans became humans (someone had to be first) that is when they received souls. You had said that you had a problem with the fact the scientist estimate a minimum population size of 50 (500?). Well with a population of that size, everyone would be related to everyone else within a couple of generations so even if Adam & Eve were just 2 out of 50 we’d all still be descended from them. (This of course raises the potential concern of “mating with animals” or whatever almost-humans would be called just before they received a soul but that has to be far less of a moral concern than the incest implicit in a literalist interpretation of the creation story)
(And I know that the Mitochondrial Eve and Y-Chromosome Adam shouldn’t really be used to support this but I like to think of it that way)
Some aspects of the doctrine of Original Sin have always troubled me. In particular why should I be held accountable for what my great great great …grandfather did? But I know that the existence of Original Sin is essential because if there were nothing to redeem then Jesus was just wasting his time down here. For me an allegorical interpretation of original sin and evolution fit hand in hand and answer my questions. We came from animals, we were selfish, driven by instinct, and didn’t know right from wrong. Then we evolved to be humans. We were given souls and with them the capacity to be better but because of where we came from we still have a weakness to act like our ancestors.
Not quite Church doctrine…but that is why they call it “practicing”. I never really get it right.
As for your questions regarding evolution and the origins of Eve, you’ve stumped me.
