Changes in gene regulation can come from viruses. Some viruses called retroviruses insert their own DNA into their hosts’ genomes to command host cells to build more viruses. But those parasitic bits of DNA can linger long after an infection. If this happens in reproductive cells, the viral DNA gets passed down with the host’s DNA. These leftover bits, called endogenous retroviruses, no longer code for the production of infectious viruses, but they can have a big impact on the host’s biology — especially if they make copies of themselves across the genome. And they have. Such viral remnants make up at least 8 percent of the genomes of humans and chimps alike. More generally, these DNA leftovers have been linked with some major evolutionary events, such as the evolution of the mammalian placenta.
A common ancestor existed in the past, and one group branched off and stayed in the trees ( Chimps and Apes ) and the other branch stayed on the ground. The ground ancestor faced different challenges than the tree ancestors which caused the brain to develop differently, which lead to humans. Surviving on the ground took vastly different amounts of brain power and thinking to survive then hiding in the trees. Combine that with eating meat and using fire and here we are.

This is how ‘Planet of the Apes’ began - really

No just viruses leaving leftover dna in genome

I think the answer is pretty simply really.
A common ancestor existed in the past, and one group branched off and stayed in the trees ( Chimps and Apes ) and the other branch stayed on the ground. The ground ancestor faced different challenges than the tree ancestors which caused the brain to develop differently, which lead to humans. Surviving on the ground took vastly different amounts of brain power and thinking to survive then hiding in the trees. Combine that with eating meat and using fire and here we are.
