First of all, I don't even know why I'm taking the time to reply to someone as purely idiotic as you are. Microevolution is EXACTLY the same as microevolution, except it takes place over a greater span of time. If an organism can "microevolve" once, it can do it again. There would need to be some sort of force prohibiting more than one evolution, which would be a fine theory if there were any evidence whatsoever for it. I'd like to add that the concept of microevolution is a concept that we've created. Each time an organism mutates slightly, does that count as microevolution? When has a species completed just one microevolution to stop evolving? Your whole POINT is built on your ignorance of the theory of evolution! I'd like to add that you're prohibiting new species from emerging when a species is really a human distinction. We categorize new "species" based on rules that we've created. It certainly is not unlikely, since the theory of evolution directly follows from the FACT of genetic mutation. "Some scientists" do not claim the earth is millions of years old, EVERY. SINGLE. SCIENTIST. who wishes to maintain ANY of their dignity recognizes that the earth is around 4.5 billion years old. Any scientist who claims otherwise would be ridiculed because the evidence of earth's age is so overwhelming it doesn't make since that even an idiot like you wouldn't get it.
First off, I never said macroevolution was impossible. I can't claim to know that. However, I do know it's very improbable, and that's what makes me doubt it. Secondly, you say scientists categorize new "species" based on rules of their own creation, meaning they can contort the rules into whatever they want until the given data can support their hypothesis. Third, our methods of dating the earth are inaccurate, contradictory to what evolutionist scientist would like to say. Fourth, genetic mutation often results in negative results for the organism. (For Wizard, that means genetic mutation usually makes life worse for the offspring. "Negative" means "bad").
It's fact that all of this happens. Even you admit that species adapt. All animals by definition reproduce, and it not getting killed is part of evolution. When it does there's a 50% chance that it's offspring will have it's adaptation. Species DO reproduce hundreds of thousands of times. Species DO have millions of years and I've asserted that new species are a human contruct. The evidence that it "could" happen is so overwhelming that we think it happened to every living creature ever.
The same adapted species member would need to reproduce, and then its offspring would need to reproduce, and so on and so on. The collective population of a species can reproduce, but you would need the
right parents to produce the
right offspring and it would need to continue for many, many generations. And as much as you'd like to debate it, organisms die. It happens. It can't be ignored when estimating the probability of it occuring.
I'd also like to add that zenthrox has the evolutionary understanding of a disabled snail.
Don't worry, I'll evolve new legs in a few million years.
