No i dont think that 'animmals' would ever evolve to become something like we are today. Firstly humans just simply wouldnt allow it, thus applying selective pressure on the particular species in question to cease further development down that pathway. The human species is an hugely selfish and competitive species and would act sharpish to keep that particular organism 'in its place' so to speak. Such an organism would prove to be ultimately competition and that just wouldnt do would it!
