"but you cannot get something from nothing, only from what exists" how then do you explain Virgin Mary and the Miraculous conception ?

It simply does not survive to procreate. Constant mutation provides the tools for adaptation or the organisms that can survive the change of the environment.
Some organism's adaptations include the ability to manipulate their environment so they may survive. That could include clothing, structures or tools.

Re: Humans Have Stopped Evolving
I was wrong about clothing. Here's a better description of adaptation in the framework of climate change.http://evolution.berkeley.edu/evolib..._climatechange
"The word adapt has different meanings in everyday language and in evolutionary biology. In common language, we might say that we adapt to warm weather by wearing light-colored clothes and drinking lots of water. Used in this way, adapting often means changing one's behavior to suit the circumstances. But in evolutionary biology, the term has a precise — and different — meaning. In evolution, to adapt means to experience natural selection that improves the function of a trait in a particular environment — i.e., to evolve via natural selection. Swapping a dark sweater for a light t-shirt is not adaptation in an evolutionary sense since it involves no evolution at all. The process of evolutionary adaptation is one experienced by whole populations over many generations, not by an individual organism over the course of a sweltering afternoon (or a lifetime, for that matter).
Evolutionary biology has a special term to describe changes in an individual organism over the course of its lifetime: phenotypic plasticity. That's a mouthful, but the idea is straightforward. An organism's phenotype is simply its set of features, and to be plastic means to be moldable or changeable — so phenotypic plasticity just means that an organism's features can be molded, or influenced to some degree, by its environment. You can think of it as the "nurture" side of the nature/nurture debate. The concept encompasses all sorts of changes to individual organisms, including developmental changes (e.g., an organism reaching a larger body size if it gets good nutrition as a juvenile, but reaching a smaller size on poor nutrition), behavioral changes (e.g., a polar bear eating goose eggs instead of seals, if seals become hard to catch and eggs are plentiful), and physical changes (e.g., a rabbit that grows white fur in the winter and brown fur in the summer). Phenotypic plasticity includes any sort of change to an individual that isn't caused by changes in its genes."

Why do you look like a rabbit then
Is that adaptation from where you live

Re: Humans Have Stopped Evolving
Species change happens all the time. Evolution is what modern biology is based on. Look at the definition of theory. Or this cut and past on evolution as fact and theory from this wiki link.http://en.wikipedia.org/wiki/Evoluti...act_and_theory
"Many scientists and philosophers of science have described evolution as fact and theory, a phrase which was used as the title of an article by Stephen Jay Gould in 1981. He describes fact in science as meaning data, not absolute certainty but "confirmed to such a degree that it would be perverse to withhold provisional assent." A scientific theory is a well-substantiated explanation of such facts. The facts of evolution come from observational evidence of current processes, from imperfections in organisms recording historical common descent, and from transitions in the fossil record. Theories of evolution provide a provisional explanation for these facts.[1]
Each of the words 'evolution', 'fact' and 'theory' has several meanings in different contexts. Evolution means change over time, as in stellar evolution. In biology it refers to observed changes in organisms, to their descent from a common ancestor, and at a technical level to a change in gene frequency over time; it can also refer to explanatory theories such as Darwin's theory of natural selection which explain the mechanisms of evolution. Fact can mean to a scientist a repeatable observation that all can agree on; it can mean something that is so well established that nobody in a community disagrees with it; it can also refer to the truth or falsity of a proposition. To the public, theory can mean an opinion or conjecture ("it's only a theory"), but in the scientific world it has a much stronger connotation of "well-substantiated explanation". With this number of choices, people often end up talking past each other, and meanings become the subject of linguistic analysis.
Evidence for evolution continues to be accumulated and tested. The scientific literature includes statements by evolutionary biologists and philosophers of science demonstrating some of the different perspectives on evolution as fact and theory."

But just for you only
My sub conscious knew that everyone loves cute rabbits, {Roasted, fried, stewed,etc} some even love them as pets.No they are scarce here by the beach, one comes in from the neighbours a black one, for a feed, it loves circling the ducks that fly in, but doesn't harm them.
