Ungar, P. S. (2007). Evolution of the human diet: The known, the unknown, and the unknowable. Oxford: Oxford University Press.
Ungar received his Ph.D. in Anthropological Sciences from Stony Brook University. He now serves as Distinguished Professor and Chair of Anthropology at the University of Arkansas. In this book, Ungar discusses the evolution of hominin diets, the importance of diet in order to understand the ecology and evolution of distant ancestors and their relatives, the hominin fossil record, dental morphology, mandibular biomechanics, and the paleontological evidence for the evolution of human diet. This book was published in 2007, so it is fairly recent. In is not biased because, for the most part, it states different methods used to examine fossilized teeth and the evidence found from these methods.

Hublin is a French Paleoanthropologist, and the founder and director of the Department of Human Evolution at the Max Planck Institute for Evolutionary Anthropology in Leipsig, Germany. Hublin is also a professor in this institute, as well as in Leiden University and the University of Leipzig. In this book, Bailey and Hublin discuss advanced dental anthropological research involving hominid dental fossils. They describe several techniques used to examine these fossils, which have led to discoveries concerning hominid evolution. Bailey and Hublin explore humans’ dental morphology, diet, and growth and developmental changes. This book was published in 2007, so it is fairly recent. It is not biased because it is stating facts regarding research and advanced methodologies used to analyze fossilized
Over the last few hundred years, more and more has been added to the world’s fossil collection, fossils from all over the world. New theories have been created and old theories have almost been proven about the evolution of man. For example, we have proof that different species of man existed with certain types of DNA sequences and instincts, some we may not have anymore, or some that other species did not have back then. Even though it is subjected to much debate, one of the most widely accepted theories however, is that Homo sapiens interbred with the slightly more primitive species of man, the Neanderthal.
A study performed by Martin Hausler and Peter Schmid of the University of Zurich, Switzerland, appeared in the October 1995 issue of Journal of Human Evolution, igniting controversy over the 1974 Australopithecus discoveries in Hadar, Ethiopia. The most famous of the Hadar specimens is the 3-million-year-old skeleton, “Lucy,” who was recovered by paleoanthropologist, Donald Johanson. In his article, Shreeve presents the methods and findings of Hausler and Schmid’s study as well as some counter arguments from other scientists in the field.
He claims that a better diet requires spending more time and resources on food, just like the people of the past did. Pollan attributes their surpassing health to this practice, but in his article “How Junk Food Can End Obesity”, David Freedman paints a different story. Freedman describes how examinations of ancient non-Western remains revealed “hardened arteries, suggesting that pre-industrial diets…may not have been the epitome of healthy eating” (514). This discovery seriously undermines Pollan’s assumption that we should follow the lead of our ancestors because even though they spent a greater amount of resources on food and ate absolutely no processed foods, they still suffered from some of the same diseases which Pollan claims his eating habits will curb. As an opponent of processed foods, or “foodlike products” (Pollan 426), Pollan advocates eating whole foods. As many people have a similar opinion, he is not alone in this, but he is misinformed. Freedman reveals that after examining the nutrition labels on various unprocessed, whole foods, he found that many contained more fat, sugar, and sodium than processed foods (512). If unprocessed foods underwent the same scrutiny as processed foods, perhaps this common misconception could be prevented. The basic premise of Pollan’s essay is that a better diet will lead to better health. While we could all benefit from a better diet, “findings linking food type and health are considered highly unreliable (Freedman 518). Freedman discusses the multitude of nondietary factors such as air quality and exercise that render such studies untrustworthy. Pollan might be a well-respected author of nutrition books, but this does not mean that his theories are free of
The human archaeological record is a long and undefined story that may be the most complex question researched today. One of the big questions in human history is the disappearance of the Neanderthal people from the archaeological record around 30,000 BP. While for thousands of years Neanderthals and Anatomically modern humans crossed paths and perhaps lived in close relations, we have yet to really understand the degree to which they lived together. My hypothesis is that these two hominids, Neanderthals and Anatomically Modern Humans, interbred exchanging genes after Modern Humans dispersed from Africa and creating like cultures and material remains. The differences between Neanderthal and Modern humans are not only physical but also genetically evolved and this research will determine an estimated amount of admixture between the two groups.
The idea that early hominids were powerful players in the ancient is slowly slipping away. Evidence is emerging that our ancestors were not great hunters, but scavengers that roamed the savanna looking for leftovers. Pat Shipman, discusses how it would be possible for early hominids to survive as strangers and how this method of cultivation affected human evolution. Shipman, uses the marks that stone tools, and teeth would make on the bones of prey animals as evidence for her hypothesis. She theorizes that early hominids weren't mighty hunter, but cunning scavengers.
This paper has shown how Homo sapiens had several advantages over the Neanderthals including better diets, better tools and just better luck. The Neanderthals could not survive the harsh climates they were thrust into and eventually died out. In this paper I looked at how Homo sapiens and Homo neanderthalensis had co-existed but the disappearance of the Neanderthal ius due in some part to the appearance of the more culturally advanced and genetically superior Homo sapiens. Although the How and Why of how Neanderthals went extinct, it is clear that Homo sapiens had a part in their demise. In the last one hundred and fifty years that we have been studying humans we have seen them come from savage brutes, to Homo sapiens respectable contemporary. If we had not gotten lucky in the past, Neanderthals could be studying us today.
Most of their evidence comes from the fossilized bones of Neanderthals and Cro- Magnons, or modern man’s ancestors (Shreeve, 150). There is a definite difference between their bone structures, and it may be a significant enough difference to divide them into species. There is a set of traits that distinguishes Neanderthals. Their general proportions are short, robust, and strong. Males and females of all ages have thick bones, and very pronounced muscle and ligament attachment sites. They also have distinct facial and cranial features. They have a large skull with no chin, a significant brow-ridge, and a large nasal opening (Shreeve, 49-150). They have large brains, around 1400cc, that protrude in the back, causing an occipital bun in the skull (Lecture, 4/19). Cro-Magnons on the other hand look more like humans do today. They are more slender and not as muscular, with chins and rounder skulls with slightly smaller brains among other traits.

“The Cooking Enigma,” by Richard Wrangham seeks to find the role of cooking in human evolution. The author begins by introducing a view that cooking is insignificant and has no influence on evolution. The alternate view is that cooking is important and led to several biologically defining features of humans, such as small guts, small teeth and slow life histories. Both views agree that cooking improves food nutrionally and makes it easier to eat and digest. Digestion consumes a lot of energy, especially when digesting hard food. Cooking may speed and ease digestion, although further experiments are needed. This may be vital, because minor dietary changes have far-reaching effects. To illustrate, the author offers an example comparing chimpanzees and gorillas. Both are frugivores and can supplement their diet with fibrous foods. However, gorillas can live solely on fibrous foods, while chimps cannot due to digestive and dental adaptations. This difference has impacted the ability to live in diverse environments for chimps and gorillas. It is possible that the need to rapidly develop d...
Nutrition is a very controversial and confusing topic. One day coffee is bad for you, but the next day it is good. Alcohol is detrimental for our health one day, but the next day red wine is the elixir of life. There are dozens of diet plans and they promise a leaner and healthier body. There is the 3-Hour Diet that involves constantly eating small portions of anything we want to eat. The latest diet craze, the Paleo Diet, is based upon eating foods that our “hunter-gatherer ancestors” would have thrived on during the Paleolithic era. And there is the Blood Type Diet, the South Beach Diet, the Macrobiotic Diet, the Mediterranean Diet, and the list goes on. But who and what should we believe? Well, there is an optimal diet for humans and the answer might surprise many.
The name Leakey is synonymous in most people's minds with the successive dramatic discoveries of fossilized hominid bones and stone artifacts that have, over the years, pushed the origins of true man further and further back in prehistory. Less flamboyant than her husband, Louis S. B. Leakey, or her son Richard Leakey, Mary Leakey was the "unsung hero,” of the clan for years, even though she was, in fact, responsible for many of the spectacular Leakey finds, including the nearly complete skull of Zinjanthropus, which was at first thought to be the missing human evolutionary link. Mrs. Leakey finally received a measure of long-overdue public recognition with her discovery, in 1978, of 3.5-million-year-old fossilized hominid footprints at Laetoli in Tanzania, proving beyond a doubt that the australopithecines had walked upright.

It is human’s relationship with food that has solidified the continuous adaptation and survival of the species. The various ways that adaptation occurs in nutritional anthropology show a diverse response to change and pressures, from developmental to cultural that can manifest in adulthood and either prove to optimize fitness or illustrate maladaptive traits.
Thesis: The tooth morphology of robust australopithecines suggests that Australopithecines spent most of their time consuming hard materials.
The increase in brain size may be related to changes in hominine behavior (See figure 3). The third major trend in hominine development is the gradual decrease in the size of the face and teeth. According to the Microsoft Encarta Encyclopedia ’98, the fossil evidence for direct ancestors of modern humans is divided into the category Australopithecus and Homo, and begins about 5 million years ago (See figure 1). Between 7 and 20 million years ago, primitive apelike animals were widely distributed on the African and, later, on the Eurasian continents (See figure 2). Although many fossil bones and teeth have been found, the way of life of these creatures, and their evolutionary relationships to the living apes and humans, remain matters of active discussion among scientists.
