Role Did Diet Play in

598)

The study concludes that, “These few observations provide a fascinating window into the way in which new dietary regimes can affect neurotransmitter synthesis and thereby influence broad-based activity patterns in the brain” (Blumenberg et al. 598).

3. Conclusion

There are many theories about the way that diet affected evolutionary selection in hominids. There is little doubt that diet played a significant role and that brain size is related to a radical change of diet in the distant past. However, what scholars are also at pains to point out is that diet should be seen in conjunction with and in relation to other factors, such as social structure. As Spuhler (1959) states,

The change to a partially carnivorous diet had extremely broad implications for the social organization of early hominoids” (Diet, Evolution, and Culture). Diet and other factors should be considered in the intricate and immensely complex task of attempting to understand our origins through the evolutionary selection process of hominids.
