I dunno, given the constipated nature of many scientists, they might do better thinking outside the box.

But thinking outside of the box that is scientific method is a wee bit much to ask.
I read it. Here we have salamanders that were originally defined as subspecies of one species based on morphology. Subsequently, with biochemical and molecular data they believe that they are not one species but seperate species. The same old problem of defing a species is present but 'all well and good'.
One problem is that there is no evidence of the ancestral salamander from which they evolved. Since I accept evolution as a theory I understand that there must have been one but until there is a link this doesnt pass muster.
I'm curious as to what you think would even be evidence that one existed, anyway, considering you hold fossils in such contempt.
In addition, since the driving force of evolution is selection why is there no mention of (for example) the seperate niches that these seperate species inhabit. Darwins classic descriptions of the finches and their presumed changes in response to habitat are notably absent here.
But niches aren't the only driving force behind evolution, you know. There's sexual selection as well.
Totally anecdotal. That doesnt mean its wrong, but no evidence is given that goatsbeards did not exist in NA etc etc.
These comments may seem like nit-picking or handwaving but they are the kinds of criticisms that are given by any scientific reviewer of any journal publication.
Seriously, you're being a tad bit naive to think that this stuff hasn't been gone over by scientists time and again very critically. I mean, they LIVE for shredding the hypotheses of others.
Theoretically a single stable mutation could cause that difference. I dont accept a single stable mutation as evidence of evolution.
Or did you mean speciation? You seem to be switching terms willy-nilly here.
Someone wants to call it micro-evolution, thats fine, but the transformants I made last week are still the same species that I started with and some will have more than one mutation.
I'm not sure what examples you're specifically refering to.
We can focus in on the London underground mosquito I cited before, if you like. I'm sure you'll have a fascinating observation that the we can't prove the mosquitos weren't underground before the tube was built...
Compared to the billions and billions of animals that have lived on the earth and the complexity of that life over a billion years I'd call it two or three bits. The super lotto is a better bet.
If fossils are so useless, what does it tell us when we can line up a series of fossils and see evolutionary development of the horse from ancient ancestors? I mean, you can literally line up the fossils and see the progression. The same is true for fossils of hominid skulls.
So your mischaracterization stands as just that: a blithe denial of the evidence sans any substance.
Strange, I've no Italien in me.
Not quite, but I suspect you'd be quite surprised about how critical and conservative other scientists can be about judging the merit of specific evidences of evolution.
You seem to vacillate wildly between accusing scientists for not being conservative enough to being too conservative... I think you're just flailing now.
This particular discussion began with my denial of "observation of evolution" not with whether or not evolution is accepted as fact despite the lack of concrete evidence.
Heres what I use: "a scientific hypothesis that survives experimental testing becomes a scientific theory".
A fact: "a concept whose truth can be proved; "scientific hypotheses are not facts".
