Evolutionary Adaptation

"A reproductive community."

What's vague about it? You don't know what reproduction is? You don't know what a community is?

No, you could define it that way - it's just not very useful. I mean, every living organism shares certain characteristics - DNA genetics, protein-based enzyme chemistry, adaptation of population through evolutionary mechanisms - which, in your conception, would lead to the conclusion that all living organisms are in the same kind. Which, if you consider a kind to be "the group of all organisms decended from a common shared ancestor", as some creationists do, that's true.The definition of species I've just laid out - called the Biological Species Concept - is the definition used in science. Determining if two organisms are members of the same reproductive community is, of course, not a trivial problem, especially if they're both dead. But in most cases its obvious if two organisms are part of the same reproductive community, like, if they were mating with each other when you observed them in the wild.

The code is altered during meiosis. That step where the information is taken from the parents? Sometimes new information is added, through mutation.

Actually we find that's not true. Often the genetic code of a creature contains not just the information for the body parts that it has, but for body parts, tissues, cells, organs, and systems that it used to have, previously in its evolutionary history.For instance, human beings can't manufacture Vitamin C. That's why we have to ingest it to survive. But we have the gene to do it, only it's in a deactivated state. Our evolutionary ancestors were able to synthesize that vitamin, and we inherited the gene, only it's got a stop codon somewhere in the middle, so it doesn't work.

I don't get why you think this is the case. Information is often added during the generation of gametes by meiosis. Mutations occur that are not corrected. Changes happen that are not undone. Information decends to the offspring that did not come from the parent.These aren't articles of faith, or something; these are direct observations of meiosis.

All things do die out. Well over %99.9 of all the species that have ever existed are now extinct.Dying out is a fairly common thing in evolutionary history. Every species, eventually, becomes extinct.
