What are some of the falsafiable theories behind evolution?

Don't dismiss people who have studied science for years because they do not align with your prejudices and opinions. All aspects of evolution are falsifiable, because it is a scientific theory. They are exceedingly unlikely to be false, however, because of the exceptionally large body of supporting evidence. This means that no one observation now could conceivably overturn the theory, but it could cause refinement. Young earth theories, on the other hand, require changes to the very basics of our understanding of the whole of science, from the most fundamental principles upwards (i.e. the very basics of quantum theory). These are the most accurate theories that have ever existed in the history of manking, so it is staggeringly unlikely that they are wrong. It is more likely that god is a piece of cheese on the end of a pygmy shrews nose.

Evolution is fact. It's backed up by literally thousands of individual pieces of knowledge that all fit the model of evolution. Minor details to the evolutionary model are always in question, but nothing can change the basic model. The only thing that would prove evolution to be false, would be the appearance of god in person. That would have to include the execution of some really big miracles to prove that he is who he says he is. In other words, until the Rapture happens, Evolution will never be proven wrong. But that is never going to happen.

I think it would be much easier to answer the question " what are the falsifiable theories behind Faith" ? the answer there would be "every theory"

Viruses like HIV would have to stop mutating or evolving. Since, mutation is one of the mechanisms of bioogical evolution.Viruses and bacteria constantly mutate and evolve. So far evolution and mutation have not taken a break for someones religous beliefs. The American Astronomer & biologist Carl Sagan wrote; " Evolution has forever to get it right " Something like that. I see it like this; Evolution is the greatest engineer. But, because evolution has no human face. It's not easy to accept by some humans. Who want to believe in Dieties with faces,intellignece,planning and peronalities. Somehting in our own immage. Like a personal god in our own immage who created a being in his own immage. Im not saying that there was no intelligence behind what has unfolded after the Big Bang. Never say Never,right.

I am not sure if or how the age factor would effect the theory. The way to prove the theory false is to know it well enough to be able to use it to make a prediction and demonstrate that the prediction is false in a repeatable experiment. The original theory as put forward by Darwin had a lot of problems that he was himself aware of and at the time were unsolvable. He did not have a way to figure out genetics and how the traits were passed down. It was Mendel in 1866 who published the answer to that. The problem so far is that all of the predictions made by evolution theory that have been tested have been found to be true. If you can discover a prediction and show a negative result to that prediction you will be cheered immensely and might even become famous. There are large awards for this, the Nobel prize is only one. Good luck in your attempts.

Before answering, I checked some of your previous questions. If you want to avoid being entirely idiotic, go and read anything by Richard Dawkins.

the gay population keep increasing.

if all adaptions are to move the creature up in the food chain or to improve the secies why did some mammals go back to the sea and live there like the dolphins or porpoises or the whales ot the seals and so on isnt a chain back into the water a step back from the future unless we are odd for developing legs and arms and should devolve back to a fish like critter

That mankind evolved from monkeys - absolute josh. The whole evolution thing is absolute nonsense
