It has often been said the vegetarian lifestyle is the best lifestyle. Eating fruits and vegetables over meat can be very beneficial and can also lead to long life. But a research group from Lund University in Sweden has come out with a whole new theory. According to them, the carnivore aspect of human is a big reason behind the evolutionary success of humankind.
Elia Psouni of Lund University acknowledged the fact that eating meat and duration of breast feeding has been a known fact for a long time but there was not even a single study that could link up both. She said, “Eating meat enabled the breast-feeding periods and thereby the time between births, to be shortened. This must have had a crucial impact on human evolution”.
After the early humans started to eat meat, their new higher quality diet meant that the women could wean their children earlier. It also enabled the women to give birth to more children during their reproductive cycle. This eventually helped in the gradual population growth. The researchers compared 70 mammalian species and found clear patterns which linked high quality meat diet and faster evolution. As the early human started to eat, it also led them to hunt, which was a decisive step in human evolution.
As the early humans started to hunt habitually, there was a need for communication, planning and the use of tools, which acted as a domino effect. As the humans started to visualize the need to better hunting techniques, it might have triggered a psychological pattern which resulted larger brain. Having meat in the diet also helped in the development of their brain which led to many new inventions as well as discoveries.
