Enterprise established it as a result of Klingons experimenting with human augment DNA and it getting out of hand. It probably didn’t need to be addressed in universe, but I thought it was a fun retcon.
Comment on What are some of the biggest continuity errors in Star Trek?

No that is actually somewhat the explanation why they look more human. It is explained in Enterprise, the Klingons try to create some super soldier serum, but that kills them. Phlox helps them create a cure, but that makes them look more humanoid. I think at the end of the episode they say that it might take centuries to revert this effect
