Due to the damaging effects that mutations can have on genes, organisms have mechanisms such as DNA repair to prevent or correct mutations by reverting the mutated sequence back to its original state.
These truncated proteins frequently are unable to function properly or at all and can possibly result in any number of genetic disorders depending on the gene in which the insertion occurs.
we need a chat room on this so we can "talk" with out long replies that take for ever...
any ways: it is true that all it is doing is editing existing info, not adding new info.
so it would never change into something new.
and if you can study and show me evolution happening, not adaption or mutation, because mutation is not changing for the better and adaption is just changing,
take eye colour, just because i have adapted blue eyes because thousands of years ago people lived in ice areas where blue eyes helped (or something) is not changing me, or evolving me if that were so i would be superior... so am i???
The THEORY of evolution is just a THEORY.
The formal scientific definition of theory is quite different from the everyday meaning of the word. It refers to a comprehensive explanation of some aspect of nature that is supported by a vast body of evidence. Many scientific theories are so well established that no new evidence is likely to alter them substantially. For example, no new evidence will demonstrate that the Earth does not orbit around the sun (heliocentric theory), or that living things are not made of cells (cell theory), that matter is not composed of atoms, or that the surface of the Earth is not divided into solid plates that have moved over geological timescales (the theory of plate tectonics). One of the most useful properties of scientific theories is that they can be used to make predictions about natural events or phenomena that have not yet been observed.
A scientific theory is a well-substantiated explanation of some aspect of the natural world, based on a body of facts that have been repeatedly confirmed through observation and experiment. Such fact-supported theories are not "guesses" but reliable accounts of the real world. The theory of biological evolution is more than "just a theory." It is as factual an explanation of the universe as the atomic theory of matter or the germ theory of disease. Our understanding of gravity is still a work in progress. But the phenomenon of gravity, like evolution, is an accepted fact.
Thank you.

look at my real other post

so everyone is saying, oh no evolution is a "proven fact" well then prove it with a bit better than: its umm um proven? umm. if you think evolution is right then PROVE it! so far i have given real info and you just push it aside and say, na i just made this post for the people who just like to disagree not prove anything or progress.
thnak you

Of course not all mutations are functional. They are essentially random. The majority of mutations are neutral, but multiple neutral mutations can add up over time leading to a new functional gene sequence. Anything to say that's on topic?
TRIMming the genome.
Some monkeys have a mutation in a protein called TRIM5 that results in a piece of another, defunct protein being tacked onto TRIM5. The result is a hybrid protein called TRIM5-CypA, which can protect cells from infection with retroviruses such as HIV. Here, a single mutation has resulted in a new protein with a new and potentially vital function. New protein, new function, new information.
Although such an event might seem highly unlikely, it turns out that the TRIM5-CypA protein has evolved independently in two separate groups of monkeys. In general, though, the evolution of a new gene usually involves far more than one mutation. The most common way for a new gene to evolve is for an existing gene to be duplicated. Once there are two or more copies, each can evolve in separate directions.
The duplication of genes or even entire genomes is turning out to be ubiquitous. Without a duplication of the entire genome in the ancestor of modern-day brewer’s yeast, for instance, there would be no wine or beer. It is becoming clear that every one of us has extra copies of some genes, a phenomenon called copy number variation.
The evolution of more complex body plans appears to have been at least partly a result of repeated duplications of the Hox genes that play a fundamental role in embryonic development. Biologists are slowly working out how successive mutations turned a pair of protoHox genes in the simple ancestors of jellyfish and anemones into the 39 Hox genes of more complex mammals.

that is not true there is only so many mutations that can become about. its like the codons that make amino acids in deoxyribonucleic acid, lots of different sequences but only so many proteins that can end up being made in the end. And no new proteins are ever made over time is there???
