Description Of Birth Of Our Modern Diet

617 words - 2 pages

For some, it might be hard to imagine how the Paleolithic diet was able to thrive millions of years ago in comparison to our diet of processed foods today. Our modern diet was created in response to changes in the biological trends over time as well as the innovations in culture. We can examine these changes by studying the human evolution through a biological perspective, while observing the changes in culture through an archaeological perspective.
Often we can look at the evolution of humans and their trends to answer questions about living humans today. Since the split of the African ape and hominid lines six million years ago, our earliest ancestors from the genus Homo were bipedal and had the earliest evidence of stone tool technology (Relethford, 45). Bipedalism was an important evolutionary trend that contributed to our modern diet, because it allowed us to walk upright and have stone tool culture (deFrance, 2013). Although the origin of meat consumption is still unknown, it is suggested that the early hominid hunter gatherers used their tools for scavenging, which may have contributed to the shift in diet from strictly vegetarian to more meat consumption (Blumenschine, 2). Scavenging allowed early hominids to have more dietary options, because they could use their simple tools to extract meat from animals (O’Connell, Hawkes, Jones, 356).
As our diet began to change from significant evolutionary trends, such as stone tool culture and bipedalism, our physical traits also began to change (deFrance, 2013). Fossil evidence suggests that the shift in our diet that involved more meat consumption resulted in simpler genetic adaptations (2013). For example, meat eating led to a favoring of larger brains among our early ancestors (2013). Gut morphology also evolved and became specific to different diet types (2013). Sharp incisors and a small...
