There are no specific species listed in the creation account and, as we all well know, species can produce variety. So no one could give an direct answer to that.
So wait,
this versus
this is within-species variation? (Pick any living bird species, it makes no difference. Seriously. Look at what you're claiming.)
Well then you should be able to classify this mutation, is it a gain of function mutation or no?
Yes, since Nav1.8 now has the ability to bind venom components.
Sure there are other stimuli. The article was vague on that point, but lets take a closer look. They did not say the reaction to the venom was prevented or there were any changes to Nav 1.7 channels. That and they also mentioned a "new kind" of painkiller would suggests the initial signal from the Na+ channels reacting to the venom was unaltered. They said the signal was prevented from traveling any further, suggesting the signal along the axon was what the mutation altered. That would dull any pain, not just venom. This is just a guess, but I would imagine that mutation could cause these mice freeze to death before they even knew it was cold.
Yes, I double-checked, the pain-killing effect does indeed extend to any pain stimulus. It doesn't, however, last forever as far as I can tell. Poor mouse would have to continuously get stung by scorpions to completely stop feeling pain.
You missed the point. I did not say speciation does not happen.
Then what on earth were you trying to say when you wrote,
"It's just as Eternal Dragon pointed out, variation within a species and variation to a species are two different things"?
Species are reproductively isolated, so that any speciation occurs as a result of mating tells us they are the same species.
(1) Offspring who are
reproductively isolated from their parents are not. (2) Correct me if I'm wrong, but as far as I know, hybrid speciation is not the only kind that has been observed. (3) Reproductive isolation is not a binary property.
What we do not see in the fossil record or otherwise is speciation by Darwinian evolution.
What, pray tell, do you mean by "Darwinian evolution"?
Man has evolved to reach conclusions based on rigorous testing of assumptions and reviewing objective evidence.
Heh, perhaps the whole problem is that we didn't. To paraphrase
Mark Crislip of Science-Based Medicine: we evolved to survive reality, not to understand it.
I just want to ask a question and it may sound like a silly one.
So you believe that a colony of mice like creatures, if they had to constantly run uphill and say flap their forearms while doing so to evade predators, would then develop enough mutations to enable their forearms to turn into wings? (New blood vessel layouts, new tendon locations, muscles, etc.)
Perhaps. Mutations are kind of unpredictable. Or perhaps they'd come up with something else. Or go extinct.
And then enough other mutations to develop feathers, navigational skills, egg laying ability to become a......bird like creature?
Certainly no. If mice evolved flight, they would evolve their own flight adaptations starting from the possibilities presented by the mouse body. Do bats have feathers? Did pterosaurs have feathers? Do insects? No. Evolution can only work from what chance and history give it. Flight feathers are pretty complex structures that you'd
definitely be surprised to see evolve twice.
All because they were trying to avoid a predator that they could have avoided by simply running faster or hiding better?
If it were indeed simpler to run away or hide, then flight might be an unlikely thing to evolve. Now, what if the mice lived in trees and jumped from branch to branch? What if they had protofeathers they used to impress their mates or keep their pups warm? Again, the starting point can have a big influence on where you end up.
I was sort of thinking it was you who recently posted that video of how flight in animals developed. Maybe it was someone else.
It showed a dino running up a hill, flapping it's small arms and that is how evolutionists think wings (flight) came about.
The WAIR hypothesis? I think that's by no means the accepted explanation. You should ask a proper dinosaur nerd about this, but IIRC the idea only works if you already have bird-like mobile shoulder joints, which early winged dinosaurs didn't.
