As you see, it's just facts. That's how it is. No point in denial.Again you are trying to present horrible evidence as if it were law.
The mitochondria endosymbiotic theory is again just a theory.
Not until recently; there was considerable evidence for it, but not quite enough to qualify as a settled theory. The mitochondria look like bacteria, with bacterial membranes, their own circular (bacterial) DNA, and other features. But we didn't really have an example of endosymbiosis being observed to evolve. Now we have at least two observed cases. Would you like to learn about that?
On top of that the DNA that they extracted from from the lizards came from their tail clippings and the DNA of the lizards is exactly the same as it was originally.
The mitochondrial DNA is the same. However, as you learned, mitochondrial DNA is just the way mitochondria reproduce in cells. It's not the DNA of the organism itself. MDNA evolves fairly quickly, so that is a good way to check ancestry.
It does not matter which traits emerged from their gene pool, it is the same species of lizard.
We don't know. As far as I know, no one has tried crossing the evolved population with the original.
But macro evolution is argued on the family level of taxonomy.
Speciation. Microevolution is evolution within a species. Macroevolution is the evolution of new taxa.
Macroevolution Definition
Macroevolution refers to the concept of large-scale evolution that occurs at the level of species and above.Macroevolution - Definition, Examples and Quiz | Biology Dictionary
Macroevolution refers to the concept of large-scale evolution that occurs at the level of species and above. Macroevolution can be used to describe the differences between two closely related but distinct species, such as the Asian Elephant and the African Elephant, which cannot mate due to the...

And in all that there has been absolutely no instance of macro evolution occurring.
There are many such examples. Even many YE creationists admit the evolution of new species, genera, and families, and sometimes even more.
If macro evolution were to occur anywhere it would be with rabbits and it doesn't.
Bad assumption. As Darwin pointed out, a well-fitted population, in a constant environment, would be kept from evolving very much by natural selection. Those wall lizards, for example, evolved a new digestive structure, because they were placed in an environment that offered few insects to eat, and had to depend on plant matter.
All we ever see is micro evolution occurring as natural selection breeds out traits losing them and making the species less genetically diverse. That is reality.
No. For example we see the evolution of sticklebacks in lakes diversifying into several genetically-distinct populations over time. They became more genetically diverse.
Novel physiological challenges in different environments can promote the evolution of divergent phenotypes, either through plastic or genetic changes. Environmental salinity serves as a key barrier to the distribution of nearly all aquatic organisms, and species diversification is likely to be enabled by adaptation to alternative osmotic environments. The threespine stickleback (Gasterosteus aculeatus) is a euryhaline species with populations found both in marine and freshwater environments. It has evolved both highly plastic and locally adapted phenotypes due to salinity-derived selection
Sticklebacks adapted to divergent osmotic environments show differences in plasticity for kidney morphology and candidate gene expression

However, theories are in proven, they are not fact.
Theories explain facts. We observe evolution, which is a fact. And there is a scientific theory that explains it. As you see, a hypothesis becomes a theory only after its predictions have been repeatedly confirmed by observation. But in science there is no such thing as logical certainty. Logical certainty is when we know all the rules and apply them to particular instances. In science, we observe the particulars and infer the rules, like a child learning a game by watching others play it. There's always the chance that we missed something. Which might seem shaky to you, but nothing else humans can do, works better for learning about nature.
