The more things change, the more they remain the same. Before we developed culturally, we were hunter gatherers. This meant that people ate nuts, fruits and leaves that grew naturally and then hunted wild animals for protein. Women were designated gatherers and men were hunters. This is definitely based on risk and workload that these gender roles were based.
However, recent evidence from archeology and studies by evolution anthropologists have revealed that the divide was not clear cut. Women also engaged in hunting as much as they were the designated gatherers. The study shows that they may not only have hunted the small game but went for the big game as well.
