In reality, the protohumans seen in Beast Wars aren't really accurate to what we know of such species of hominids. Likely, they are both stylised to fit within story requirements and to suit the relatively limited CGI technology of the time. http://transformers.wikia.com/wiki/Protohuman#Notes Hey, last I checked this isn't a religious or political message board. We're talking about the protohumans in Transformers. In terms of the Transformers universe, humans are sentient animals and evolution is not a theory. That's the whole point of Megatron trying to wipe out the protohumans so they wouldn't develop into the future humans that helped the Autobots defeat the Decepticons.
