But since there is a discrepancy, we are left with only one conclusion: The bacteria evolved.
Not meaning to barge in like this, but perhaps you should have explained why this experiment is so important in regard to demonstrating mutation and selective pressure. Bacteria reproduce by mitosis (fusion fission). This means that the daughter cells are exact replicas of the mother cell. And so on and so forth.

I stand corrected

I wonder that if mudskippers were extinct right now, if evolutionists would make the argument that they were really creatures in transition from water to terrestrial, or vice versa.
But there currently exist many species of animal that are transition from water to terrestrial. We don't need to look at animal that are already extinct to use as an example.

Re: definition from scientific sources
Well, I'm going to just stick my nose in and comment on something without having read the entire thread (this is against my earlier position in another thread of course... I am a natural born hypocrit).
​
Evolution is simply the change in allele frequency over time. What's wrong with this definition and why do we need to come up with another one?

Re: So what is this evolution thing, anyway?

Just curious, Dr A, do you know of any evolution going on without the inheriitance of genetic traits.
The evolution of memes.
​
Some people on this forum have claimed there are "traits" that are not heritable.
Well, some traits are truly not heritable. For example, a trait caused by a specific mutation that renders an individual completely sterile will of course not be heritable.
​
I have agued that a "trait" must be heritable or it is not a "trait."
According to wikipedia, "A trait may be any single feature or quantifiable measurement of an organism."
​
But if we want to argue definition here, I guess you can define it whatever you want.
