Human Evolution
Human Evolution Human Evolution, the biological and cultural development of the species Homo sapiens, or human beings. A large number of fossil bones and teeth have been found at various places throughout Africa, Europe, and Asia. Tools of stone, bone, and wood, as well as fire hearths, campsites, and burials, also have been discovered and excavated. As a result of these discoveries, a picture of human evolution during the past 4 to 5 million years has emerged. Human Physical Traits Humans are c
The Neolithic
The Neolithic
The Neolithic Paleodental evidence suggests that after the divergence of early hominids from the hominoid ancestral line, a gradual increase in consumption of harder and/or more abrasive foods occurred - most likely nuts and seeds. This change probably increased intake of vegetable fat (mostly non-serum-cholesterol raising in nature) and would, perhaps, have facilitated overall access to food energy, but probably had little other nutritional effect. About 2.5 million years ago, however, there is

What Are Missing Links? Australopithecus anamnesis In 1965 a research team from Harvard University discovered a single arm bone of an early human at the site of Kanapoi in northern Kenya. The researchers estimated this bone to be 4 million years old, but could not identify the species to which it belonged or return at the time to look for related fossils. It was not until 1994 that a research team, led by British-born Kenyan paleoanthropologist Meave Leakey, found numerous teeth and fragments of

Australopithecus
Australopithecus By: Chris Stewart Date: December 15th 1996 Biology There are many types of the hominid called australopithecus, which means southern apes. These were small ape-like creatures(with a height between 107cm and 152cm) that showed evidence of walking upright. It is difficult to tell whether these begins are humans or apes. Many of their characteristics are split between humans and apes. The many species of australopithecus include A.(australopithecus) ramidus, A. anamenesis, A. a
Human Evolution and the Fossil Record
Human Evolution and the Fossil Record
Human Evolution and the Fossil Record Scientists continue to debate the history of man. It is generally agreed upon by the scientific community, however, that humans evolved from lesser beings, and this essay will function to provide evidence to support this claim. Several points will be outlined, including the general physical changes that occurred between several key species on the phylogeny of man, and a discussion of dating methods used to pinpoint the age of the fossils. This essay will beg

Human Evolution
Human Evolution Evolution is the complexity of processes by which living organisms established on earth and have been expanded and modified through theorized changes in form and function. Human evolution is the biological and cultural development of the species Homo sapiens sapiens, or human beings. Humans evolved from apes because of their similarities. This can be shown in the evidence that humans had a decrease in the size of the face and teeth that evolved. Early humans are classified in ten
The Human Brain
The Human Brain
The Human Brain The Human Brain Through the use of molecular biology it is thought that the hominidae family first appeared about 5 million years ago. Based on this time frame it is believed that an African Hominoid lineage was present shortly before that time, approximately 10 myp, which contained the common ancestor to both the chimpanzee and human. The split into proto-chimpanzee and proto-human occurred during the last million years of the Miocene epoch. (Changeux and Chavaillon pg. 61). The

Medicine Malaria at Decline of Rome Signaled in Child Cemetery This article was interesting in the sense it gave us another reason to believe that 1) malaria was a epidemic disease in the past, 2) why Attila the Hun did not continue his invasion of Italy and 3) the decline of the Great Roman Empire. To me, it was a horrifying and poignant experience to dig up a grave of infants (49 so far and the excavations are still continuing). Dr. Jose Ribeiro, an entomologist at Arizona concluded from the b
