You are missing the evolution of Man and civilization.
1. Dental structure. Our teeth evolved to eat both meat and plant matter.
Humans were wild people and they didn't know how to farm. So they used to kill animals. They used to eat raw meat. Then cooked. So canines size decreased over the centuries.
2. Digestion. We are able to both tolerate and fully extract nutrients from most plant and animal sources. Exceptions include cellulose and chitin.
Its based on acid present in stomach. Snakes can devour entire animal and their stpomach acid even digest bones. Humans acidity level is quite high so there is no problem. Hope you know about the stomach lining continuoulsy created.
3. Primate Studies. Other primates, our closest living relatives, are also omnivores. This list includes Chimpanzees, Orangutans, and Gorillas.
They are majorly vegetarians. Few eat ants and sometimes small animals. They are behind evolution and can't arm.
4. Nutrients. Strict vegans must carefully watch the source of their food in order to ensure complete nutrition. In the modern world this is relatively easy, however prior to the neolithic, when we were primarily hunter-gatherers,it would have been vital to gather nutrition from whatever source was available, animal or vegetable.
I know Jain people who haven't eaten a single egg, leave aside meat. They are much more healthier than others. Meat is rich in protein but its high in cholesterol and may not provide all nutrients. You can leave on strictly vegetarian diet with proper nutrition but can't do same with meat. Like Vitamin C is available on fruits. That's why sea man used to take lemons even when they had food in form of fishes.
5. Archaeological Evidence.Evidence from our earliest ancestors indicates that we have always consumed meat. This evidence includes bone evidence in proto-hominid fossil sites and coprolites
Archaeological evidence shows the evolution of civilization. When they started farming, the meat dependency reduced. In Indian culture many people didn't even eat meat.
Now let me tell you one thing, exposure to violence and blood like Cutting the heat of Goat, Cow etc. in front of a child makes him less emotional towards violence. He/she accepts violence as part of life for survival.
If you look at the history, the meat eaters have been the ones who caused maximum number of killings. Whether it was Christians or Muslims.
Rapes were part of Muslim invaders and meat eaters.
Christians and Barbarians were also meat eaters.
well In Islam u can't just eat meat..
there are somethings u need to know..
halak things are allowed..
no blood is allowed....
so such animals are allowed which swallow their food..
so such birds are allowed which eat with claws..i.e eagle
no such animal is allowed which eat other animal.
well as rapes issue on muslim invaiders chk our Muhammad Bin Qasim...
people of subcontinent know Islam because of him...
people Became muslim because of theirs behavious...
Same goes for Tariq Bin Ziad and khalid Bin waleed..
About sultan Sulah Ud din ayubi u need to chk out comments by Richard the lion heart...
Islam spread coz of behavious and u suppose people became muslim as muslims were rapiers??
well u need to correct urselve..
the one who rape should be killed by hitting him with snall stones according to Islamic laws...
No rape cases can be seen by those invaders who deserve to be called muslims...
if ur talking about mughals then u can ve right...
as they are just something else..
Akbar was a Mushrik(non-Muslim)....
all kings lifes were outta Islam(expect Arungzaib but he didnot treated non muslims as Islam advised us to as far as i know) or we would be seeing maby libraries and universties and developed India/Pakistan rather than quillas,baghs,minars and mehals. .
