Star Trek- Hollywood Critic

In Star Trek, there are many different aliens that the Starship Enterprise people encounter and come by throughout the movies and series. This hollywood critic is on how all of these different speciees (Vulcans and etc.) all look similar or exactly like humans. So Vulcan's only difference in their appearance to humans is there eyebrows and their ears. If you think about it then the Vulcans, unless they were from another planet and just became native to Vulcan, would have had to evolve from something like a rodent or some other animal in that planet. Vulcan has no animal similar to that of a human or anything human-esque on it. This is very annoying and I don't see why they would have some of the main races look like humans. I could understand if it was really like a budget cut and they couldn't get suits for them but I also don't because like some other things have suits. Also, I could really say this about multiple human-esque aliens in other movies.
