Dmanisi Skull Essay

637 Words3 Pages

The Dmanisi skull 4, also known as D3444 with its mandible D3900, is one of five Homo erectus skulls discovered in Dmanisi, Georgia. Described in a publication in October 2006, it is believed to be about 1.8 million years old. Dmanisi D3444/D3900 is believed to be a Homo erectus adult female with a marked edentulous (toothless) grin. The cranium (D3444) was found first in 2002 and the mandible (D3900) was found later in 2004, immediately adjacent to the spot the cranium was found. The brain has an endocranial capacity of 650 cm. It is difficult to determine if tooth loss was a result of either advancing age or pathology. However, due to substantial bone resorption (bone loss) of both the mandible and maxilla, tooth loss occurred years before death. It is hypothesized that this individual either was able …show more content…

It is quite interesting, because before this discovery, it was thought that the first humans only left Africa 1 million years ago. However, archaeological evidences show that there were already Dmanisi hominids in Dmanisi 1.77 million years ago. It was also thought that the first humans out of Africa were tall, big-brained, and well-developed stone tools. However, the Dmanisi hominids were small, had small brains, and used primitive tools. The Dmanisi also provided paleoanthropologists with a new site to discover. In the exhibit for The Humans Outside of Africa, there were different skull fossils that were studied and categorized as potentially male or female. However, it is also notable that there were fossils (D2700 and D2735) that were examined to be that of an adolescent. Therefore, this provides paleoanthropologists with a basis for studying the Dmanisi hominids on a generational basis, from adolescent to old

    Ancestors in Our Genome, addresses the continuingly advancing disagreement upon whom our closest ancestor is within the great apes, described as the hominoid trichotomy debate. The author, Eugene E. Harris examines many different sources of evidence within the book, and with the help of improvements in biological and DNA technology he helps discover who our closest ancestors were. Also when we were first separated from them and how the separation took place. Although there have been many recent advances in technology, a large number of unanswered questions are still a mystery within our genome and evolution from the great apes. Chapter one discusses the debate of morphology - studying fossil evidence of the great apes - versus molecular

    On the contrary, scientist began to unearth new fossils in Asia and Africa, that were thought to be human ancestors that came hundreds of thousands of years old after Piltdown Man. They were found to be less human with small skulls, but without authorization to the Piltdown bones and efficient dating methods, they were all but ignored because they contraindicated Eoanthropus dawsonii. It was not until 1949, when the bones were discovered to be around a hundred thousand years old; with the application of newly discovered fluoride dating. Subsequently, they were fully analyzed in 1953 and exposed as a hoax. Scientist discovered that the jawbone indeed came from a female orangutan and was less than 100 years old.

The victim's dental records were compared to the teeth of the unidentified body, and a match was made. This case led to the development of a national database of dental records, which has since become a standard tool for forensic odontologists. During World War II, forensic odontology played a crucial role in identifying the remains of soldiers killed in battle as dental records were used to identify thousands of soldiers

  • Pre Clovis Culture In The Americas

    Questions have been raised in the current “Clovis-First Model”, due to genetic and linguistic evidence that suggests that people might have pre-dated said model. To unambiguously knock that ball out of the park, so to speak, we’d need to present clear cut evidence that not only proves a Pre-Clovis entry, but also fills in all the proverbial blanks. One of the most promising methods of doing such a thing is archaeological digs, primarily in the Monte Verde site. Following that, genetic testing and carbon dating is also a viable candidate for proving that a Pre-Clovis culture did exist. These tests confirm that humans, as well as their tools, were present in caves prior to Clovis times.

  • Out Of Africa Hypothesis Research Paper

    Some paleoanthropologist accept the hypothesis that one singular archaic population of Homo sapiens had advanced cultural capabilities and replaced other archaic forms of humans somewhere between 200,000 and 60,000 years ago. However some suggest that the “out of Africa” hypothesis is flawed in the sense of molecular evidence. Charles Darwin was one of the first to propose the “Eve” hypothesis. He suggested that modern humans came from apes in Africa, Thomas Huxley further supported this theory by stating humans share an evolutionary relationship with African apes. Darwin’s theory was supported when fossils of small brained hominoids were found.

    Critical thinking questions: physical anthropology textbook 1. Given that you’ve only just been introduced to the field of physical anthropology, why do you think subjects such as skeletal anatomy, genetics, nonhuman primate behavior, and human evolution are integrated into a discussion of what it means to be human? The study of physical anthropology integrates the subjects of skeletal anatomy, genetics, nonhuman primate behavior, and human evolution because anthropologists look to the fossilized remains of hominins to see what their environments were like and what they ate. In addition to these sub fields, anthropologists look to skeletal anatomy to see any evolutionary change or if the hominin had died from any diseases and how old and tall

Some of these include the finger marks from the Rouffignac cave in France, dating to 18,000-9,000 B.C.E. and the handprints from the “Cueva de las Manos” in Argentina, from around 8,000 B.C.E.

    This discovery gave the evidence that was needed to validate the out of Africa theory and it is difficult to debate the theory with this scientific data. Another thing that validates this theory is the low amount if genetic variation amongst human across different races. This low variation amongst human genetic make-up suggests that our modern human species arrived from a small group of Homo sapiens. Academics hypothesize that the group was roughly 10,000 to 50,000 people. Another thing that supports the out of Africa theory is the higher genetic variation in Africans.
