Which are stronger pound for pound Herbivores or Carnivores?

[parvez]

During those times when herbivores must have evolved the vegetation should not have been as diverse as today. But ofcourse they must have had better protein yield than today's plants. Even then at least some of the herbivores did not seem to have met the requirements of essential amino acids. They must have randomly and voraciously fed on these plants. Point number one, they must have evolved as carnivores after feeding on their dead counterparts in hunger of obtaining essential amino acids. Point number two, those who got essential amino acids must have developed instincts to kill the now weak improperly nourished counterparts and hence gradually evolving as carnivores. Reply
