Are Humans Carnivores or Herbivores?

After browsing on Wikipedia in the "Plant-based diet" section, I noticed some things that I felt needed to be changed. After doing much research on the topic, it's clear to me by science that humans are natural-born herbivores, not omnivores or carnivores like Wikipedia suggest, 

"Humans are omnivorous, capable of consuming diverse plant and animal foods. Fossil evidence from wear patterns on teeth indicates the possibility that early hominids like robust australopithecines and Homo habilis were opportunistic omnivores, generally subsisting on a plant based diet, but supplementing with meat when possible." source: http://en.wikipedia.org/wiki/Plant-based_diet#Humans

 I went in myself after researching and changed the short paragraph to this:

"Humans were not always omnivores. Back in prehistoric times, there were no hunting tools for humans to hunt, so they were gatherers. Another fact that proves that humans are meant to consume plant foods only is by looking at their digestion compared to real carnivores. Human intestines are much longer in length than carnivores. Carnivores, such as lions, intestines are much shorter because they're meant to process meat quickly and pass through fast. Humans, on the other hand, having their intestines much longer, can lead to clogged arteries when digesting meat because it takes much longer to pass through. Another major fact that shows humans are herbivores is by looking at our teeth compared to carnivores. Human teeth are short and flat. Humans also chew side to side (which is a herbivore specific trait) whereas carnivores chew up and down to tear through raw meat. Yes, humans are capable of eating meat, but they are not natural born carnivores or omnivores according to human physiology. " source: http://www.adaptt.org/veganism/humans-are-herbivores.html   

 I feel as though it is important for people to be correctly informed on this topic, and I believe the post before was misleading as it could make people believe that they are in fact, natural carnivores, like other animals like lions when we are not. It only takes some little research to spot the major differences between humans and real carnivores based on our physiology.

Wikipedia is one of the most popular websites that people go to for information, so it is important that the information is true and accurate, which is why I felt it was so important to change to correct information that is backed by facts.
