Again, you are confusing actual mutations in Evolution with comic versions of mutations.
In evolution, one individual life don’t simply “morph into something else”.
Your ISS astronaut example, gravity may have affected their circulation by gravity, but if the conditions -
- are temporary and/or,
- their children and grandchildren are not born with this physiological abnormality...
...then this isn’t Evolution.
What I mean by “temporary” in my first point, if their conditions return to normal after some days, weeks or months back on Earth. I am talking about their changed circulation physiology are not locked on permanently.
In Evolution, the genetic traits that make life different to tiny degrees from their ancestors, must pass from parents to offspring, through their genes or through the sequencing of their nucleic acids (eg RNA, DNA).
A single dog cannot physically morph into cat. And a dog cannot give birth to a cat. What you and most creationists are claiming about “Evolution”, are not possible in actual Evolution.
Evolution, and I am talking about real Evolution, doesn’t work in either ways.
There are limitations what science say what Evolution “can” and “cannot” do.
And Peter Parker cannot exhibit super strength, speed, and like a spider, the abilities to climb walls and ceilings, or spins their own webs. This is nothing but fantasy.
I have tried several times to explain this to you, that Evolution cannot happen to a single, individual life cannot magically turned entirely into something else.
Physically being able to “morph” isn’t Evolution, but you misunderstanding what Evolution is capable of.
