The conclusive evidence for evolution: Endogenous Retroviral DNA.
A retrovirus is a virus that replicates by inserting itself into your DNA. That's why retroviruses (like HIV) are characteristically hard to cure. But because these viruses embed themselves in human DNA, they leave a precise fingerprint. The genome is so large that it is mathematically impossible for a virus to embed itself in exactly the same location in two different individuals.
Therefore, if two people carry the same retrovirus DNA in the same location, we know that those two people descended from the same ancestor who was infected with that virus and then passed it on in their DNA.
Well it turns out that all humans share certain sequences of retrovirus DNA with all Chimps and Bonobos. The only plausible explanation for this is that all three species share a common ancestor.
Indeed, when we look through the genomes of other primates we find viral remnants that are shared between some species and not others. We have used these viral fingerprints to reconstruct the entire primate family tree.
The result is 100% in line with the fossil record, molecular evidence, and phylogenetic trees based on morphological traits.
When all of this is considered together, there is simply no alternate explanation that even comes close to explaining these empirical observations as well as evolution.
...Case closed.
