So If the "theory" is a proposed description, explination, then the part that states we come from a common ancestor is this part of the diffinition.
If I understand your question(?) correctly, then yes, the concept of common ancestry is part of evolutionary study, and thus part of evolutionary theory. It would be easier for you to understand what a scientific 'theory' is if you use either 'study' or 'explanation' in its place.
Also, try to understand that its not "a" common ancestor, but many different teirs of them, because it is literally a family tree.
I think you'd understand this better if I use an example family's genealogy to illustrate the point. In this case, let's say Simonas Urbonas represents Man, (Homo sapiens) and Jonas Zakaras represents Pan, (chimpanzees). Aldona Zakaraite is the most recent common ancestor between them, but he is obviously not the only "common ancestor" depicted on this chart.
Ancestral phylogenies in evolution are the same sort of thing, just on a larger scale.
the next part would be about evolution and the last part gets me. the, and being able to be tested through experiments.... Was not the fruit fly experiments done for this part.
Among innumerable others, yes.
they did not produce anything.
Yes they did! That was the first time macroevolution ever occured under direct observation in a controlled laboratory setting for one thing. For another, subsequent experiments isolated and revealed Hox genes.
"eight master regulators were soon discovered. When a broader spectrum of life was probed for similar control genes, a remarkable and unprecedented discovery was made. The same eight genes, with only minor variations in the genetic code, were present all across the animal world. Literally, from fish to fowl, we share the same master control genes that sculpt the basic body plan."

I do not see how th epredicting part uses the idea of being from a common ancestor.
There are too many ways to list, and you wouldn't understand any of them until you grasp the basics first.
We have never seen anything change into anything else, the reason given is because we dont have enought ime or cant live a million years.
(1) Nothing ever gave birth to another, fundamentally different thing. As I explained on my website,
"Evolution never suggests that one thing ever turned into something else. Every new species or genus, (etc.) that ever evolved was just a modified version of whatever its ancestors were."
(2) We have actually seen one species beget a new species many many times already. We've directly observed this on dozens of occasions in real time both in the lab and in naturally-controlled conditions in the field, and I know I have explained this to you before. So why are you still making the same mistakes?
We trsted and observerd bacteria and such that reproduce very quickly Put still havent seen anything to prove the idea of a common ancestor.
Yes we have. In the sense that a court of law would apply that word, we have indeed proven the concept of common ancestry many times over with geology, genomics, comparative anatomy, in-depth character analysis of evidently derived synapomorphies, developmental biology, and of course palaeontology in addition to the fact that we've been able to map genetic orthologues in so many different things already. We've traced four main stem lineages as the 'roots' of all the hundreds of different breeds of domestic dogs, (for example) and molecular biologists working on
the Shape of Life Project with the Marine Biological Laboratory in Woods Hole, Massachusetts have traced a single base root genome of the literal grandaddy of animals.
Once again, in case you somehow haven't seen this before, let me again quote my professor of cellular biology, (and a devout Christian):
"The evidence of taxonomic relationships is overwhelming when you look at the comparisons between the genomic (DNA) sequences of both closely-related and even distantly-related species. The DNA of yeast and humans shares over 30% homology with regard to gene sequences. Comparison of the human and mouse genome shows that only 1% of the genes in either genome fails to have an orthologue ithe other genome. Comparison of non-gene sequences, on the other hand, shows a huge amount of divergence. This type of homology can be explained only from descent from a common ancestor. The probability of these things being a coincidence, which I guess would be the argument of creationism and intelligent design, is statistically so small as to be negligible."
--Jill Buettner M.Sc., geneticist with the human genome project
I th ink it should be called the theory of common decent instead of the theory of evolution since evolution is a fact and testable and observed and predictable ect.
And so is common ancestry. My primary interest is in taxonomy, and I've seen several lineages revised or corrected according to objective tests of various types.
well if i believe in a God that is ABOVE us in science and in knowledge then i would think this would not be a problem. I dont have a problem with not knowing everything. You saying it is form a spell makes you continue to feel that it is not possible because saying spells sounds bad sounds fake or fairytaleish.
It couldn't sound any other way even if you chose how to phrase it.
I just dont see the theory from common descent from what i observe from evoltuion or science. Maybe it is because i refuse to or because i dont know enough or have studied enough.
All of the above. That, and some of your religious leaders appear to have been lying to you your whole life.
either way it makes no effect on my life. I am who i am because of what i have experienced in life, just like you. which to me includes things i cant explain through science. This doesnt bother me.
That wouldn't bother me either. Its believing things on faith that always bothered me. Because that always seemed dishonest even before I started noticing all the fraudulent claims creationists and other pseudoscientists make.
i know you can test evolution but can you test the theory of common ansector.
Yes. After you have some idea what some of these terms refer to, I'd be glad to explain how to do that.
I know we are like 96,97% like apes
We
are apes, and we are 95-98% like chimpanzees.
but jellyfish watermelons and clouds are 90% alike or the same thing H2O but very different. so the few % that is different can make it not even close to the same.
I first heard this particular argument on a radio evangelist show that was on at a friend's house when I was eleven years old. I was stunned that any grown-up could be that stupid. Unfortunately, I said exactly that out loud and discovered that my friend's parents weren't any smarter than the idiot on the radio.
