Error #1 Adaptation within a species is not an error. It is a fully programmed response in the genetics of all species to adapt to changes in environment and food supply. It is confined to small changes, not monumental ones that change one "kind" of organism into a completely different "kind" altogether. Bacteria remain bacteria. Viruses remain viruses no matter how much they mutate....they won't become cows over a few million years!
Mutation is an error in the duplication process of the amino acids that form our genetic material. If you don't know that, then I don't know how we can reasonably discuss this topic. Evolution occurs by the same mechanism that causes cancer, with the difference being that some mutations are benign. Adaptation isn't a programmed response at all. The entire point of the theory of evolution by natural selection is that what we call "adaptation" is the result of random mutations, but that the randomness is mitigated by natural selection, which means that the more viable ones will tend to proliferate over time. In short, polar bears didn't have something in them that automatically turned them white when they started living in the snow; the lack of pigmentation was a random mutation of the sort that occurs frequently in many species (tigers, alligators, humans, et al.), only in the case of polar bears the white mutant bears happened to have a much easier time hunting and surviving, so they had more kids, and their genetics came to dominate the region.
As for this imaginary species barrier, you do realize that there's a line of microbial colony cells that have evolved from the cervical cancer of a human woman, right? They're well known and used in a number of experimental applications because of their resemblance to human tissue, even though they're not strictly human anymore. The fact is that all our DNA does is code for the formation of proteins. There's no magical "human" gene. Again, cancer happens precisely because for that reason: a single mutation can cause cells to create tissues that are not part of the species in question.
Error #2 This is an assumption. You have been led to believe that it is "inevitable" by those who believe this and strongly promote it.
I'm not a Jehovah's Witness, so stop assuming I operate like one. It's not an assumption, any more than the assumption that the sun will rise tomorrow. Lacking a magical barrier between species, which cannot be demonstrated to exist, and which can be demonstrated
not to exist (and which would be incoherent to begin with, as species are arbitrary and vague categories to begin with), a sufficient number of mutations
would inevitably lead to our recognizing it as a significantly different creature. People have observed this with a number of creatures in laboratory settings, but you're not interested in the science, so you won't have heard of them (and won't look them up in any case). But let me put it this way: both great Danes and chihuahuas come from mutations and selective breeding from wolves as a starting point. Wolves and coyotes also come from a common ancestor (and are still interfertile). That's not so hard to understand. Go one step further, other canines come from a common source that differentiated over time. Go back to that point and the difference between canines and, say, felines isn't apparent.
So where do you draw the magic line? Drawing it between bacteria and cows is just rhetorical puffery, based on appealing to "common sense" instead of actually engaging with the topic.
Error #3 You have no evidence that this genetic barrier does NOT exist. Science has not proven that this barrier does not prevent one "kind" from evolving into another completely different "kind" of creature, no matter how much time has elapsed. There were no witnesses to these events except the Creator himself, and he has told us a completely different story.
You're the one positing a magic barrier between species (which are arbitrary categories invented by humans, which we often revise, making this discussion even more absurd). Nobody needs to prove that those magical barriers
don't exist. You would have to prove that they do, which you can't, since there's absolutely no evidence. And no, ancient creation myths are not scientific evidence. If you have to play that card, you've already lost.
Error #4 Is it obvious? Or only obvious to those who seek to support that pre-conceived conclusion? When you have no actual evidence, you fill in the gaps with "something" you believe is plausible......it's called assumption, speculation, educated guessing, presumption...or any number of words that describe what science does....but none of it is "fact".
You misunderstood me. What I meant was that it's obvious
why we haven't observed in real time the kinds of changes that require millions and billions of years to play out, not that the conclusions are obvious. Setting that standard is ludicrous because it amounts to claiming that human knowledge can never encompass anything we can't see right in front of us, which is tantamount to chucking the entire discipline of science out the window. Inference based on evidence is a source of knowledge. If you call anything that people don't see play out in front of their eyes "mere supposition," "bare speculation," etc., you're basically saying that science is impossible and that people don't actually know much of anything. For example, if you say the world is round and that the moon is made of rock, that's pure speculation, since you haven't directly experienced those things yourself. In short, you're doing immense violence to the very concept of evidence and analysis.
Error #5 The accusation that anyone who dares to question your chosen belief system is "stupid". Peer pressure doesn't just work on teenagers you know.
Please. You demonstrate over and over again your scientific illiteracy, as well as the fact that you're unwilling to educate yourself on the subject. There's no peer pressure here. It's a simple description of how you operate. Nobody is trying to pressure you to change your mind because your mind is impervious to evidence, logical argument, and anything else that might contradict the absurdly literalist way you've been indoctrinated to read the Bible. You, on the other hand,
constantly insinuate that those who disagree with you only do so out of some mental or moral deficiency. The difference is that whereas the JW indoctrination I mentioned is plain for anyone to see (you're a very good example, basically making my argument for me), what you're peddling is this absurd idea that all of science is a hoax, there's no such thing as evidence or the proper analysis thereof, and all scientists do is believe whatever they want to believe and concoct a vast, world-spanning conspiracy to delude people (ostensibly because they hate God or are slaves to Satan or something). One of these is evident right here in this thread; the other is bone-headed.
As for the rest, Biblical fundamentalism is not a middle ground. If it seems that way to you, you must be pretty far gone already. It's contrary to all human knowledge, both religious and secular. Actual Biblical scholars know better than to read
Genesis as a factual account of the origin of the world and its inhabitants, as did its original authors and audience.
