I think you meant apes evolved INTO humans. Anyway. That's easy--ever heard of endogenous retroviruses? Basically, when a retrovirus infects an organism, it copies part of its own genetic material over the host's DNA, altering it. Over hundreds of generations of random mutation, the remnants of the retrovirus still remain, with small, unique errors in their transcription. Humans and chimpanzees share several retrovirus remnants, with identical mutations. The chances of the mutations being identical in chimps and humans while arising in separate incidents is virtually impossible, thus we can conclude that humans and chimpanzees shared a common ancestor--and, by observing the mutations of the retrovirus remnant, we can even estimate the time period. This points at a date about eight million years ago, which correlates well with the fossil record.
It is already known that humans didn't come from apes themselves but from something in between of which there is no fosil record! Going from apes to humans is impossible. Like going from a orange to a banana. It's just strange and not realistic.

Endogenous retroviruses are retroviruses derived from ancient infections of germ cells in humans, mammals and other vertebrates; as such their proviruses are passed on to the next generation and now remain in the genome. Retroviruses are viruses that reverse-transcribe their RNA into DNA for integration into the host's genome. Most retroviruses (such as HIV-1) infect somatic cells, but some can also infect germline cells (cells that make eggs and sperm) and once they have done so and have been transmitted to the next generation, they are termed endogenous. Endogenous retroviruses can persist in the genome of their host for long periods. However, they are generally only infectious for a short time after integration as they acquire 'knockout' mutations during host DNA replication. They can also be partially excised from the genome by a process known as recombinational deletion.
If endogenous retroviruses are the answer. This brings up twice as many questions! how could humans evolve from a serious of unexplained temporary viruses that the apes carried and then we morphed into humans? A specific range of special infections cannot magically alter apes genetics into humans. Some random lucky mutation doesn't make sense and there is nothing to back it up. The problems with natural selection make this theory complete nonsense. Unique errors DO NOT remain, because of the aquired knockout mutations during host DNA replication. They can also be partially excised from the genome by a process known as recombinational deletion. As stated above. I listed the differences between these gentics in this thread already. There is to many of them. Too much is unknown to conclude your pie in the sky ape theory. Infections are not progressive. Viruses, are not progressive.

This means it's difficult to imagine how it's possible because it's absurd. Frankly everything else stated is a weak explanation aswel.
