We haven't. Dogs (Canis lupus familiaris) are currently classified as a subspecies of wolves (Canis lupus).Mgoblue201 said:Why, then, have we labeled a dog as a separate species?
You're right. I screwed up. I should have went with another comparison, like the little brown bat and some of the derivative species which are incredibly similar. I was simply trying to express that we label things different species for far less than gills or flippers.Tntnnbltn said:We haven't.

Dawkins provided an example whereby if you held hands with your mother, and she with hers, and your grandmother with her mother etc etc all the way back with one ancestor per metre, after about 300km you would be looking at an ape that for all intents and purposes resembles any of the other great ape species.
And logically, if that ape held one of her other daughters hands who then held her daughters hand etc etc back down the line of progeny, you would eventually come to a modern chimpanzee. Your distant cousin.
Bananakin said:I don't know about anyone else, but my biggest trouble with understanding evolution was never regarding how one mammal could evolve into another, say. I have no problem believing that a human and a mouse shared a common ancestor: the homologous structures that we share make it pretty easy to visualize how that could be the case. And that's pretty much how it is for me with all reasonably complex animals: fish, birds, reptiles, etc. With the complexity already there (internal organs, body systems, appendages, whatever) evolution has plenty to work with (so to speak), and it just doesn't seem much of a stretch for one species to drift into another. The trouble for me was always in how such complexity came to be in the first place (and I shouldn't say trouble - I accept evolution completely, of course). I just mean that some things are just less obvious or intuitive than others, like: how did multicellular life come to be? How did sexual reproduction start? How did the first internal organs develop? Or the cardiovascular system? Obviously these kinds of questions have been answered by biologists, but most people just aren't informed to that level. And of course, some things like that probably have fairly complex explanations. My main point here is just that, I wonder if people seeking to explain evolution to doubters would be better served focusing on the "early" stages of evolution - ie, painting a sort of timeline of how life made each of its jumps in complexity: from unicellular to multicellular to invertebrates to vertebrates, or whatever it is. That, I think, is the larger disconnect that more intelligent doubters of evolution might be seeing: not between monkey and man, but between amoeba and arthropod. After all, it's the complexity of life around us that is the key reason so many people are unable to accept evolution.

Those are great ones. I was thinking of the little brown bat vs. the Indiana bat myself.Tntnnbltn said:They are, however, different species. They have different genetic information, different bird songs, different nesting behaviour, and the different species do not reproduce.
Socreges said:But each of his questions demands several pages of text to properly answer. As he conceded:
"Obviously these kinds of questions have been answered by biologists, but most people just aren't informed to that level. And of course, some things like that probably have fairly complex explanations."
I think if there is such a thing as an "intelligent doubter" of evolution, they should be bright enough to know where to go if they truly want answers to such questions. Google "how did ___________ evolve" and read the first or second result. Easy.
And I think we've already demonstrated anyhow that doubters of evolution are doubters for a reason. They normally already act as though they are informed and are therefore careful not to make specific charges (e.g. how did sexual reproduction ever evolve!?) because they know there are likely specific answers. Instead they stick to the predictable, vague charges.
JGS said:Where's your evidence it happened otherwise?:lol
What makes you think I need to verify anything to you if you can't extend the same courtesy? If you don't believe God did it, why would I care?
I didn't say it wasn't the best one you have. It being the only/best option most scientists accept does not by itself make it a stronger argument.speculawyer said:What?
It is the best scientific theory we have. That is hardly crackpot.
Granted, our knowledge is very limited since we are trying to explain something from billions of years ago with no direct physical evidence to examine.
Would you consider the talking snake theory better?
Mumei said:Nonsense.
If someone were to say, "God did it," then he would need to be able to point to evidence for that claim, just as someone would need to point to evidence to support a claim that evolution explains speciation. If you've made a positive claim, then it is your job to prove (or in this case, at least demonstrate sufficient evidence for) that claim.
The difference is that there is evidence one can point to in support of the latter, but no one can point to any evidence supporting the former.

I've seen the videos before. To your other pointsMario said:There is no evidence "God did it" either, so by extension that would make Christianity a "crackpot hypothesis"?
If you actually watched the video I linked, you might gain an appreciation for some of the processes that *might* have been involved. The nature of science, thankfully, means that we will continue to form hypotheses, investigate, experiment, and explore until we raise our level of understanding and beyond, even if there is no clear understanding or evidence right now.
None of what you said even remotely verifies how life started, just how our planet is perfect for supporting it.Srsly said:There is more evidence pointing toward abiogenesis than the "God did it" theory that creationists like to espouse. Just look at early Earth geology and how certain chemicals and elements came into existence on this planet and solar system thanks to heat and pressure and then cooling . There are rocks billions of years old that serve as a window into how this planet came to a state that led to the early precursors for life. Volcanoes produced CO2 and methane that led to the organic soup that eventually led to amino acids that led to more complex amino acid that led to single-celled autographs with DNA -- very simple organic machines with the right instruction set to replicate. In fact, amino acids can be recreated in labs. Give it time and we will go from being able to create amino acids to being able to create life with actual DNA from amino acids.

Each time someone brings up a lab experiment to prove how life started in the wild, it drives me crazy.
To make clear, I think it is higly unlikely that life will be created by man anytime soon, but that does not mean I have any doubt that they will succeed in creating some things. So in short:
I think it's neat.
JGS said:1. Christianity is already viewed as a crackpot hypothesis at best for atheists, so the playing field is far from level as it is.
2. The possibility of creation has nothing to do with a particular religious belief. On top of that, why the need to compare/contrast with a particular religion? The theory should stand/fall on it's one rather than the idea of it being a lesser of two evils. The fact that it's brought up that way so much show there's not much meat to it.
3. Argue abiogenesis on it's own merits.
Leave religion out of it since I'm done with that subject in this thread
plus there are way too many beliefs on the matter even if ones here try to clump them together. Go to the religion thread if you have the guts/stomach for it! :lol
Nocebo said:I've mentioned it briefly before but the evolution of the inner ear in mammals is an interesting subject as it shows how body parts can move from having one function in an earlier species to another in their descendants.

I know. It's the old bait and switch to hide the weakness of your claims.Mario said:It was brought up to show the weakness of your claims it has no substance as a hypotheses.
There is no existing research beyond what is written which scientifically speaking is dicouted automatically since the other aspects to the hypothesis are not witnessed, observed, or even created in a lab.Mario said:Hard to do when you appear to claim there are none, seemingly discounting all existing research and claiming it a "crackpot hypothesis".
Others are bringing up religion.:lolMario said:You keep said that before, but here you are.
Good for you. So you should already know how I view the religious aspects of it. Why carry it to a new thread?Mario said:I already have contributed to that thread.
JGS said:Crackpot does denote a minority view though, so I'll just say flawed hypothesis since the number that follow it would be irrelevant. I guess it's less inflammatory too, but I wasn't the one who used the word at first. I just thought it fit.
This isn't about what I prefer, it's about the bold and the whacky concept that despite this major flaw, it is widely embraced on the sol basis of it being the only possible option except for one thing. It's not possible. It's not possible at each level of the RNA, amino acid,DNA, etc...danwarb said:JGS, abiogenesis is the study of how some kind of self replicating molecule arose from inanimate matter. That there's no overwhelming consensus on the matter doesn't mean there's no evidence that it happened at all, it most certainly did.
No I like defective.Mario said:I'm not sure "flawed" is an appropriate word to use either given that would suggest the hypothesis is inherently defective with some known error.
I think using the words "unproven" and "incomplete" would be more appropriate.
How big of a time line are we talking here? There's a neat vid narrated by Carl Sagan that illustrates the evolution of humans from beginning to end.I'm planning on making a section in the OP showing the timeline of Human Evolution, I'll probably use this to give aforementioned section some meat. Thanks!
It doesn't necessarily need to happen on every level simultaneously. It seems likely catalytic RNA (also known as Ribozyme or RNA enzyme) was formed before proteins or DNA. And as you already know, scientists have successfully demonstrated that amino acids can spontaneously form small peptides. Is it really that far fetched, even if there are missing puzzle pieces?JGS said:This isn't about what I prefer, it's about the bold and the whacky concept that despite this major flaw, it is widely embraced on the sol basis of it being the only possible option except for one thing.

I think people take issue with you claiming abiogenesis can't be supported even in the slightest bit. Which is clearly wrong. Since we know certain building blocks of life can occur naturally through chemical processes.JGS said:How life started is certainly an interesting subject but not one that can be supported by scientific data in the slightest- at least not at this time. It's all sci-fi. Therefore, I have no reason to embrace a belief/theory/hypothesis that has Swiss cheese holes in it just because a scientist who has no more ability to go back in time than I do says it's the truth.

But there was a time before life on Earth, and now, quite clearly, there is life on Earth.

At the end of the day, it is completely irrelevant what someone believes regarding how life started except in regards to what makes them feel better.

We know it can happen because it happened. If it happens that God did it, 'Abiogenesis Theory' should eventually include God doing it.
I'm aware of that. I said the first paragraph already, just with more skepticism.Lesath said:I don't wish to derail an evolution thread, but abiogenesis is the explanation that makes the least additional assumptions, and is therefore the most logical, however flawed you think it to be.
In trying to explain abiogenesis, scientists have proposed a set of models; it isn't some singular theory.
Well, of course it's possible to create something. The question is if it's possible for nature by itself to create something without human aid. I say no.jdogmoney said:Since the point of the lab experiments was to show that it is, at least, possible for abiogenesis to occur, which they did quite admirably, one wonders...why is it "not possible", and what would it take to change your mind?
There is no scientific evidence to abiogensis. That's the flaw!:lolMario said:Care to point out the specific "defects" or "flaws"of the current abiogensis hypothesis?
It would be useful if you link to specific scientific evidence that contradict the aspects of abiogenesis you call out as defects.
JGS said:Well, of course it's possible to create something. The question is if it's possible for nature by itself to create something without human aid. I say no.
Honestly, what would convince me is time travel, otherwise I don't see how.
I guess if, although still controlled, science was able to create the environment and let nature takes it's course and each of the steps were met toward creating life, I would be less of a skeptic.
