I think you've somewhat missed the point. A species has lots of adaptions/features like fingers, toes, liver, kidney, digestive system sexual organs. None of these can be produced in one mutation (over night).
​
So to get to this stage yould have to be able to survive as a human with half an eye, half a liver, stubby fingers.
​
You've misunderstood how evolution is proposed to work. Nobody who understands the Theory of Evolution thinks that an individual would have half an organ.
​
Take a look at australopithecus:
​
​
Its one of our ancestors and its fully formed. It doesn't have half of anything.
​
Although, sometimes we do find things that seem to be half-way done. Like this turtle:
​
MSN | Outlook, Office, Skype, Bing, Breaking News, and Latest Videos
​
But still, it is a fully formed and fully functional individual.

Hello websnarf, welcome to EvC.
​
I'm not trying to argue that you're wrong, but I'd thought I'd bring up some things.
​
There are no known animals that are immortal. They died, probably by the same process that any other animals die.
​
First off, check out this animal <--clicky:
​
quote:
Turritopsis nutricula is a hydrozoan which reverts to the polyp stage after becoming sexually mature. It is the only known case of a metazoan capable of reverting completely to a sexually immature, colonial stage after having reached sexual maturity as a solitary stage. It does this through the cell development process of transdifferentiation. Theoretically, this cycle can repeat indefinitely, rendering it biologically immortal until its nerve center is removed from the rest of the body.
​
Neat, huh?
​
I'd also like to point out another thing about immortality and death. Think of the asexual reproduction of a bacteria:
​
​
The original cell divides into two new cells. The original one hasn't really "died". And the new cells are of the same 'stuffs' as the original. In that sense, bacteria is kinda immortal... "kinda immortal", heh
​
Here's how wiki phrases it:
​
quote:
Bacteria are said to be biologically immortal, but only as a colony. An individual bacterium can easily die. The two daughter bacteria resulting from cell division of a parent bacterium can be regarded as unique individuals or as members of a biologically "immortal" colony. The two daughter cells can be regarded as "rejuvenated" copies of the parent cell because damaged macromolecules have been split between the two cells and diluted. In the same way stem cells and gametes can be regarded as "immortal".
​
So not everything really dies and some things can be said to be immortal.
​
And to counter my own argument, I present this:
