There is no second opinion about the fact that the Neanderthal Man was essentially a hunter, and therefore a major part of his diet was constituted of flesh or meat. But you cannot term him as wholly carnivorous, because there were fruits and vegetables in his diet as well. So he was a food gatherer in addition to being a hunter, and his dietary pattern was omnivorous. Interestingly, they did not reside in large groups like their ancestors of the likes of the Cro-Magnon species. On the contrary, they hunted, stayed and gathered food in about groups of four to five, which included both males and females. Off late, some more interesting aspects about the Neanderthal’s dietary patterns have been unveiled by leading scientists. Some of them suggest that some of them ended up resorting to cannibalism in the event of harsh weather conditions, and the absence of food or game. This was of course prevalent in the earlier stages, but as their tools got a little more improvised and the tough environmental conditions somewhat subsided during the last glacial melting, there is evidence that showed the Neanderthals used fire to roast or mildly cook vegetables prior to eating. All said and done, the average life expectancy of the Neanderthal Man, if we are to take into account the entire time zone, was 35 years which goes on to show how tough it was to survive and adapt in the freezing conditions, wild nature and absence of proper survival tactics that their successors eventually mastered in due course of time.
