Are you saying the gravitational point of singularity, believed to be the cause of the Big Bang, isn’t a scientific concept, or are you saying that it isn’t a metaphysical concept?
I’m not a physicist, but they tell me there is evidence suggesting it. If so, it’s a scientific concept.
If it isn’t a scientific concept, why is it being taught in science classes?
If it isn’t, it shouldn’t be. But people who study that sort of thing, admit to having evidence for it.
Bararian observes:
BTW, since we have directly observed macroevolution, and know exactly what causes it, I’m puzzled that you think there are “gaps.” Evolutionary theory (like all sciences) has questions yet to solve, but that’s not one of them.
I meant to say whether those mutations, which allows for survival, exists by accident
Various experiments have shown them to arrive randomly.
or whether it is a life process or force which protects the lifeform from being destroyed…a form of dynamic, purposeful process as such.
Haven’t seen any evidence for anything but natural causes. Do you have checkable evidence for any?
Barbarian on recapitulation per Haeckel:
We show, in utero, some features of our distant ancestors, but this does not mean recapitulation is true…
How does this demonstrate the hypothesis that lifeforms adapt itself to it’s environment through a dynamic, purposeful process of mutation, as being wrong?
You alluded to recapitulation. The evidence that mutations are random is sufficient for the other.
Barbarian suggests:
Well, show us the equations of quantum mechanics that supports recapitulation. That would be a surprise.
I am not a scientist; however, I have posted the point of view of a molecular geneticist
He’s decidedly in the minority on this, among his fellows, and while that doesn’t guarantee he’s wrong, it should give you pause unless you can grasp the argument.
You may certainly disagree with him, but his view remains valid.
No appeal to authority means much in science.
Barbarian observes:
Pretty big “if”. BTW, your blogger confused protons and electrons, … And I’m very puzzled as to why he thinks it’s impossible that the ability to vary mutation rates at specific loci could evolve. He offers no explanation, just assumes so.
It seems that in the experiment of bacteria, deficient in their ability to utilise the milk sugar lactose,mutation does not always occur at the same rate.
Which could mean all sorts of things, including a regulator that switches on or off in the presence of a substrate.
From the blog:
**Quantum mechanics tells us that the protons in DNA that form the basis of DNA coding are not specifically localised to certain positions but must be smeared out along the double helix. **
Barbarian observes:
Electrons are. Protons are tightly bound in nucleii by the strong force. If not, and they move about, the elements would change from one sort to another.
Protons can also be viewed as being non-local. The EPR experiment was performed using two protons instead of electrons.
Free protons, yes. Those bound in nucleii stay there, unless the atom changes into that of another element.
Barbarian observes:
The difference between speculating about “quantum worlds” and natural selection is that there is evidence for the latter.
Again, I’m not a scientist, so whatever valid scientific theory you might accept is ok; but this in itself does not negate nor reduces other hypothesis into being inferior.
The other hypothesis lacks evidence and seems untestable.
how does this equate to what you claim is something totally random and accidental in nature?
I didn’t. “Accidental” is not a scientific concept. And mutation rates at various loci normally have various rates, including rates of back mutation. What is random is precisely when the mutation occurs.
(sensible conclusion that eyes would not evolve in the absence of light)
Barbarian observes:
It would be a little hard to imagine an eye forming, if there was no selective advantage for it, yes.
Which is why I believe the mutations involved in the process of the development of the eye isn’t accidental, but purposeful in essence.
If so, then a rock rolling down a hill is purposeful. Neither requires any outside intelligence to happen.
Barbarian suggests:
Make it testable. And then, test it. .
Until then… well, you know.
However, my point is simply that other valid scientific theories exist pointing to evolution as a process of mutant development believed to be something other than being a random process as such.
Comes down to evidence. Which is why it doesn’t get much support.
