Hey, I have an idea! How about before you speak on a subject, you know what you're talking about first? Wouldn't that be crazy?
Meet the Gray Tree Frog, and the Cope's Gray Tree Frog. They are different species, with different cellular makeup, that cannot interbreed; this species divergence happened over a short time, potentially even a single generation, via a process called autopolyploidy. One of the two species existed beforehand, and after breeding there was a completely separate species, assuming we're using the common scientific definition of a species.
So, you're wrong, unless you want to wriggle out by using some arcane other definition of species, which I don't think is terribly far from your normal course of argumentation. But then we'd be wondering why we should use your self serving definition over the normal one.
Now, speciation events of this type are rare, but they do happen. More normally, species diverge over concurrent generations through a process of small alterations, and this has also been observed to occur, but even if it hadn't your point would make no sense, as those genetic mutations that drive evolution have been observed under laboratory conditions; by making the stand that you are, you are asserting that small changes can occur, but that those small changes can never accumulate, for some reason. But we've never observed any mechanism that prevents those changes from accumulating across the (human defined, I might add. It's not like this is some magic transcending of a natural order) species boundaries we use, so the conditions of your own argument prevent you from making it.
Your argument is self refuting, and your ignorance of the process of evolution does not bode well for your insistence on talking about it.
I'm Glad you had to jump in and open you mouth, I clearly stated
Quote:You do realize that one species of animal has never been observed to evolve into a completely different speciesand by species, I mean from one animal into another, I consider frogs to belong to the same group. I suppose you forgot that I stated a while back that an animal can evolve from it's group, but a cat cant evolve into a dog. Dogs evolve from Dogs. In that sense I don't consider the frogs to be different species.
I suppose I'd better include the quote or I'd be accused of "moving the goal posts"

Quote:this requires a much longer explanation than I feel like giving, but I will say this. I believe in evolution. It would be ridiculous to think that Noah took two of every animal on the ark. The bible says he took 2 of each sort, meaning group, or animal family and what what we have today is a product of evolution.
Ok, so let's examine "speciation" since you brought it up.
http://en.wikipedia.org/wiki/Speciation
Quote:Speciation is the evolutionary process by which new biological species arise. The biologist Orator F. Cook was the first to coin the term 'speciation' for the splitting of lineages or "cladogenesis," as opposed to "anagenesis" or "phyletic evolution" occurring within lineages.[1][2][3] Whether genetic drift is a minor or major contributor to speciation is the subject matter of much ongoing discussion.
There are four geographic modes of speciation in nature, based on the extent to which speciating populations are isolated from one another: allopatric, peripatric, parapatric, and sympatric. Speciation may also be induced artificially, through animal husbandry, agriculture, or laboratory experiments.
So we see that speciation can induced artificially through animal husbandry.
As you well know, slavery was a part of Americas history where they bred people like animals in order to pass on "favorable traits", do you consider African-Americans to be a different species of human?
