All Life on Earth (plants included), consists of the same Genetic substance DNA (a few viruses have a related molecule RNA).
If you sequence enough of the DNA of any living species on Earth, and also all the DNA that we can find in fossils, then compare them for sequence similarities, you build up a "tree" or dendrogram which shows you
exactly how each species is related to the other, and which ones have older ancestors, and when they arose in time.
There are no real "missing links" just a flow of relatedness . . . but of course not every species that has ever lived will be represented.
But it is a foolproof theory to date, because as we discover more and more fossils, we find they all fit in perfectly as predicted.
You can even reproduce "Evolution" and see how survival of the fittest by natural selection works by doing experiments in the test-tube with bacteria and introducing an antibiotic that they are sensitive to. Pretty soon you evolve a mutant which is resistant and then after time it is the predominant variant.
That is the power and beauty of science over religion.
so does the dna of all these different species contain the same chromosomes? because what you just said is a very very broad generalisation its like me saying for example that the dna or life source of a car engine is its oil, so because "oil" is present in the engine of a skoda and the engine of a mercedes does that then mean that the mercedes engine is related to the skoda engine? people are nowadays found guilty of their crimes by the tiniest molecules of dna sometimes microscopic, so if every single human being has different dna how can you tell me that every living thing that has ever lived on earth has "common" dna?
and if there are no missing links as you say then why do the best scientists, even those who created the various theorys call things "missing links" perhaps darwin needed you back then phoenix cos you seem to know more about his theory than even he knew
when you can even begin to comprehend the answers to the questions i`m asking then go back and answer the ones i asked a few posts back, until then dont even bother to come back to me as i reckon you could spend your time more wisely than trying to answer questions that have no answer in science
DNA is what makes up chromosomes, it is their building-block. Smaller molecules make up the DNA. It is the sequence of these that is both unique and conserved. Short segments of DNA make up genes. They control who you are and how you develop. There are so few differences between individuals and that is why we have different coloured eyes etc. But we are still related as Humans despite these few differences which make us unique.
DNA fingerprinting exploits sites in the DNA which can be recognised by different "cutting" proteins and that is how you get an individual profile.
"Missing link" is popular science and has no scientific merit.
If you are still asking about
where the first cell came from . . . well you can cause the synthesis of DNA in a test tube and mimic pre-biotic life. With the naturally occurring chemicals found throughout the universe you can make the precursors to DNA, then the membrane surrounding it.
The most beautiful thing of all is that
DNA can replicate itself. So from the first cell, you get many more and so on.
As for the beginnings of the Universe, well I am not a physicist, but I do know they have enough information already that there is an ongoing project which will create a mini-universe in a test-tube. That should answer that hole in time.
Do not worry . . . not in our lifetime, but at the rate we are going, we do have the capacity to fill all the holes.
