mutations are most generaly bad.
No.most are neutral--neither helpful nor harmful. That's why we can have so much variation in species.
So a mutation happens ever so slightly changing it. then the next mutation happens in the same place
No, the second mutation probably doesn't happen in the same place, nor in the same individual, or even the same generation. It happens in a different cell entirely, in a different organism, probably on a different chromosome and at least somewhere else in the gene. No reason at all for other mutations to happen in the same place to affect the same character trait. And even if by chance it did, it would still be in a different individual, whether it happened in the same generation or a future generation.
What you need to work on is this question: how does one mutation happening in you and a completely different mutation happening in your granddaughter contribute to the evolution of humanity? The theory of evolution explains this. Do you know what the explanation is?
I havent seen this type mutations happen in a way to make the theroy stick.
Where have you looked? Are you an expert in DNA sequencing and analysis? have you read published scientific papers on observed changes in DNA in a population over several generations?
It doesnt generally lead to any great change over time as in reptile to mammal. But again we have this time limit.
Right. One human lifetime of active research only allows us to see about 40-50 years of evolution directly. The transition from reptile to mammal took at least 100 million years. Do you have any reason to hold that is not enough time?
so we cannot observe such a thing happen. though we have been looking for a while and you think their would be such a animal close enough that we could possible finish its change from one class to another. but maybe not.
A change from one class to another takes a really, really long time. To go from fish to amphibian to reptile to mammal took 2-3 hundred million years. Is it any wonder no one human can directly observe it? Even a change of species can take thousands of years so it is too gradual to be noticed in one generation. It's a bit like watching a mountain erode. Over time, the Rockies will wear down to the height of the Appalachians, but you are not going to notice much change in your lifetime.
So now its neither. It will spread if that population is not killed off. or the family starting it doesnt die off. what if like say a metorite comes and kills 98 percent off. do we start all over again.
Yes, we start all over with whatever survives.
This happened twice i think they say. so we evolved from what was left.
Five times, actually and it is happening again today. We need to make a lot of changes in the way we live to keep as many species alive as possible.
Its not the finding in that idea, its that some get ate or killed etc without passing it on. how many babies do they have. generally most die off before adulthood. this adds to the odds of it happening like you say from one common ancestor.
It would seem to me to lower the odds. If most individuals die off before adulthood, there are fewer adults to be ancestors, so if one of them carries a mutation, it is more likely to get a foot into the next generation than if all the other individuals also survived. Put it this way: if the adult population is 10,000, then a new mutation is likely to appear in 0.001% of the next generation if reproduction is asexual and 0.0005% if reproduction is sexual (since it is passed on to only half of one's offspring). If the adult population is only 100, then a new mutation is likely to appear in 1% of the next generation if reproduction is asexual and 0.5% of the population if reproduction is sexual. And that is before factoring in natural selection which would increase the odds of survival and reproduction in offspring inheriting the mutation.
Yes this little common change that becomes dominate is called speciation. evolution. its not the theory of evolution.
Yes it is the theory of evolution. Maybe you don't actually know what the theory of evolution is. Here is a definition from Understanding Evolution:
Biological evolution, simply put, is descent with modification. This definition encompasses small-scale evolution (changes in gene frequency in a population from one generation to the next) and large-scale evolution (the descent of different species from a common ancestor over many generations). Evolution helps us to understand the history of life.
An introduction to evolution
Here is one from Why Evolution is True by Jerry Coyne
In essence, the modern theory of evolution is easy to grasp. It can
be summarized in a single (albeit slightly long) sentence: Life on Earth
evolved gradually beginning with one primitive speciesperhaps a selfreplicating
moleculethat lived more than 3.5 billion years ago; it then
branched out over time, throwing off many new and diverse species; and
the mechanism for most (but not all) of evolutionary change is natural
selection.
When you break that statement down, you find that it really consists
of six components: evolution, gradualism, speciation, common ancestry,
natural selection, and nonselective mechanisms of evolutionary change.

ndont say it all happen at once.
What you asked was:
"how many mutations in just the right place and time and parents and domination of parents genes etc would this take." And you also asked about an individual with a mutation finding a mate.
This sort of question only makes sense if all the mutations need to happen at the same time.
Why do you ask such a question if you understand that each mutation happens in a different cell, which is probably in a different individual, who is probably in a different generation, and is not significantly different from other individuals in its own generation? Furthermore each mutation probably affects a different part of the genome, even in the unlikely case that it happens in the same gene.
God created animal to adapt and change over time. over amny many years they change alot i would think.
Yes, God created animals to evolve, and natural selection to adapt them to their habitat and to changes in their habitat. And not just animals, but all other forms of life as well. And they do change a lot as we can see from series of transitional fossils--like those of horses and their ancestors.
but never been shown to change from fish to amphipian to reptile to mammal.
Sure you have. It is in most standard textbooks on evolution.
every thing on earth can be placed into one of these. every thing found can to.
Oh, not by a long shot. More things are placed outside of these categories than inside them. All the things that are not animals to begin with: E.coli bacteria, Parmecium (a protist), rhodophytes and other algae, all sorts of plants and fungi. Then, even among animals, there are all the animals that don't have bones: sponges, jellyfish, clams, snails, spiders, bumblebees, ants, beetles (lots and lots of beetles). The four classes you name are only one small group: vertebrates.
and guessing from just bones isnt easy and they have been wrong before.
That's why scientists don't just guess. They use many ways to test their inferences and establish what is factual. Sure, sometimes they make mistakes, they are only human, but usually something comes along to correct the errors.
You would think the way we reproduce humans would be evolving fast.
Why? Most scientists would say there is every reason we would not be. We have a huge, global population that has not broken down into isolated populations that don't interbreed. We have a long time between generations and we have few offspring per couple. That's a recipe for slow evolution, not fast evolution.
environment works for or against changes which is used alot but the environment changes alot and the animals do no how to MOVE when it does so change isnt needed.
Not all animals can move. Some remain fixed where they are as adults. And even if they can move, they can't always move fast enough or get across barriers. Clams, for example, can't move very fast or very far, so if the habitat changes quickly, they can't simply move somewhere else.
Mutations only do so much there is just to many varibles to consider that they could, even in the time given, to create everything from one common ancestor.
Right, mutations only put variation into a population and that's not enough. You need selection to get from variation to evolutionary change. You need natural selection to get adaptive change. With mutations
and selection
and speciation all affecting a population, there is lots of time for all the changes that have been recorded.
I mean you start with plants or food base then to animal and still have to have food base for what was just evolved which is probably eating whats their. Is there a book or something that has a kind of model or story of how it could have happened from the first element to cell to plant to animal to etc etc. Its easy to come up with it all when its all already here.
Most don't include "from the first element" since that is more about the origin of life and cells (abiogenesis) than about evolution. But there are plenty of sources that can take you from early populations of cellular life to the biodiversity of today. The two links I gave you above are good. If you don't mind going backwards (from us to our more and more ancient ancestors, right back to the earliest cells) an interesting, if long, read is The Ancestor's Tale, by Richard Dawkins.
There are also some interesting theories on the origin of life.
