Sample Essay on Compare and Contrast Homo Erectus Cranium

Introduction

The Dmanisi is a species of Homo erectus that was found in the Republic of Georgia at a place called Dmanisi. At this site, five different skulls which have been named specimen D2280, D2282, D2700, D3444 and D4500 were found. In this paper, comparison between skull two, labeled specimen D2282 and skull 5, named specimen D4500 will be done.

Similarities

According to Henderson, both specimens had faces and teeth which could be easily identified and described by the archaeologists. This was true in as much as the teeth and face of D2282 were deformed (4-5). Both D2282 and D4500 are also believed to have belonged to adult persons.

Differences

The differences that have been discovered in the skulls D2282 and D4500 are many. Firstly, Henderson says that the endocrinal volume of D2280 was measured at 660cc while that of D4500 is 546cc (4). Besides that, the cranial vault of D2282 was intact compared to that of D4500 which is not mentioned at all. Secondly, D4500’s jaws were so worn out that finding the teeth was a challenge. On the other hand, D2282’s had 16 teeth arranged in its mandible (Henderson 4-5). Thirdly, D4500 possesses a large supraorbital ridge and a broad zygomatic arch which is missing on the skull D2282. The fourth difference is that D4500 was believed to have been from a male because of its long face and maxilla while D2282 from a female due to the presence of a gracile muscle (Henderson 4-5).

Conclusion

Specimen D4500 and D2282 have a few similarities but several differences as relates to their endocrinal volumes, facial features and teeth. The discoveries of these skulls have made the existence of Homo erectus more real and become proof of the evolution theoryWork Cited
