Barbarian on O. gigas:
You’ve been misled. We still have this species in existence, and they still reproduce just fine, like other self-perpetuating populations.
But they aren’t self-perpetuating. They are bred and cared for by scientists.
And flower fanciers. The species is doing fine.
They would die off if they were left to sustain themselves in the wild.
Maybe. However, we have an example of a species of rodents that occured by polyploidy, and they do just fine.
Barbarian chuckles:
You mean speciation can occur without new information?
Not the kind of speciation that would be relevant to the theory of common descent.
Show me.
Barbarian on the claim that new species of flies are still flies:
And we are still primates. You find that amazing?
It’s one of the predictions of common descent.
A primate is an omnivorous mammal. Common descent didn’t predict that humans are primates.
Yep. It does. for a host of reasons. Anatomical, genetic, fossil, etc.
Barbarian on species that depend on humans:
So do Zea maize and ginko trees.
No relevance to the theory of common descent.
But it does throw your “but they can’t survive in the wild” argument in the dumpster.
Barbarian observes:
The author of that paper is dead, but O. gigas lives on. Imagine that.
The O. gigas are kept going by being bred and cared for by scientists.
And those who like primroses.
No relevance to the question of whether humans evolved from other species.
It merely demonstrates that the evolution of new species is a fact.
Barbarian observes:
And corn is “helped” along. But of course that polyploid rodent in South America had to go it alone.
They are still just polynoid rodents.
Polyploid. And they evolved from diploid rodents. Just another part of common descent.
So we know it works. Moreover, there are quite a number of polyploid wild plants that do just fine without human intervention.
They are still just polynoid plants.
You’re running out of irrelevant examples.
I think you’re going to have to do better than simple denial to get out of this one.
Barbarian observes:
Other than demonstrate the fact of speciation. BTW, even most YE creationists admit the fact of speciation. They can hardly do otherwise, since it’s directly observed:
I admit the fact of speciation also. But where are the examples of absolute speciation?
Sorry, inventing imaginary forms of speciation isn’t going to help either.
The Dobzhansky-Muller model proposes that hybrid incompatibilities are caused by the interaction between genes that have functionally diverged in the respective hybridizing species.
Barbarian chuckles:
It explains why two divergent species can’t hybridize. It doesn’t mean that they are hybrids.
Don’t be silly. Dobzhanski came up with his model after observing the hybridization of fruit flies.
You still don’t get it. The speciation wasn’t caused by hybridization. He was writing about the reason why the two species couldn’t form viable hybrids.
Barbarian observes:
Those flies would be surprised to learn that. They are still there, still reproducing, many generations later.
Of course,they are laboratory flies.
Nope. They are living in the Orinoco basin, with no help from humans at all. Did you even read the research?
And the hybrids are constitutionally weak,malformed,and sterile.
Barbarian observes:
And yet, the flies live on, completely disregarding your interpretation of genetics. Cheeky little miscreants. BTW, since Dobzhansky wrote that, molecular biology has made it clear that most mutations don’t do much of anything.
They result in speciation,remember?
Usually not. Most of the time, they do nothing detectable. You and I almost certainly have several.
Barbarian observes:
But of course, such mutations were not visible until we could examine DNA in detail.
This is one of the hazards of trying to cite papers over a half-century old, as current knowledge.
Then why did you cite the examples of O. gigas and Dobzanski’s fruit flies in the first place?
These new species are still in existance, the flies in the wild, doing their thing with no human help.
You should know how silly it is to use examples
Some creationists look on examples the way a vampire regards a crucifix.
But science works on evidence. If you want to play basketball, don’t complain if they expect you to dribble.
