Depends on what you consider proof. Paleoanthropologists believe that they have tracked the evolution of man from Homo Habilis through Homo Erectus to Homo Heidelbergensis and Homo Neanderthalensis on to Homo Sapien. And they've published their evidence to support their hypothesis. As for the evolution of life through amphibian to reptile to bird and mammal, scientists have identified hundreds of what they believe are transitional fossils indicating that progression. You may not accept their evidence as accurate but that's a far cry from saying no evidence exists at all.
Evidence may or may not constitute proof.
“Paleoanthropologists believe”
Yep, they sure do.
They can’t test the TOE all again, in controlled lab conditions, and collect the data, but boy-oh-boy can they ever believe when they really want to.
