Reading Response to White et al.: Ardipithecus ramidus and the Paleobiology of Early Hominids. In the article, Ardipithecus ramidus and the Paleobiology of Early Hominids, by Tim D. White et al. , the Ardipithecus ramidus specimen ARA-VP-6/500 from the Aramis vertebrate paleontology locality 1 (ARA-VP-1) expedition is examined in depth. The ARA-VP-1 is located in the Middle Awash and expands into the Central Awash Complex (CAC) with different localities, numbered from 1 up. The Middle Awash and CAC are important because the Middle Awash has been dated from the Late Miocene to the Pleistocene, and the CAC has been dated with strata from about 5.55 to 3.85 million years ago. The article has an in-depth description about the site locality. Including…
insight of our ancestors. Ardipithecus fossils were a crucial find to the field of archeology, which created new suggestions concerning features that associated them with modern Homo sapiens and primitive apes. The structure of the Ardipithecus has provided information which separates…
Human Evolution For many years people have wondered how the human evolution started and why are we different from other species. Science brings us to new knowledge of how humans evolved in this world and the transition of apes to humans. The Human family tree starts from the Ardipithecus groups about 6 million years ago, the next one is Australopithecus group is about 4 million ago, the third one is paratroops group is about 3 million years ago and the last one is the homo groups is…
other hand, splitters suggest that species that dispersed around the globe, they population divergence happened and thus variation increased among them. Splitters theory asserts that Homo erectus became isolated reproductively and each species evolved independent of each other and splitters follow cladogenesis which refers to diversifying selection and it divides species into more branches. Splitters and lumpers agree on grouping, but they disagree on what the differences mean. The difference in…
Hominid Evolution is the evolution of human lineage. Dating back millions of years with Sahelanthropus tchadensis, it's the oldest found hominid, dated around 7 million years old. This species is known for its cranium and it's very small brain size, and a specific amount of both jaws and teeth. It has many, ape-like features, such as; small brain size, brow ridges and small canine teeth, which are characteristic of hominids. However, this along with the fact that it comes from around the…
angled shafted knee joints, distal femur and prominent patellar lips were just a few of the many similar characteristics linking to humans. The most closely related piece of evidence that made it clear was evidence leading towards the spinal curvatures giving her a permanent upright stance enabling her to walk on two feet in the way we do now. In 1992, after a solid decade of thoroughly searching for the missing link, an anthropologist of Aramis discovered an unknown stage of evolution more than…
wonder if modern humans have the ability to survive, or if another, greater species will be created. The main part of the exhibit contained fossil skulls that were linked to species so people are able to see what kind of skull it is and where it was found around the world. Some of these places included Africa, Europe, and Asia, which relates to the some of the information that we read in our textbooks. The different kinds of species were quite significant with: height, body shape, cranial…
using the characteristics of the skull and where each of them was found. Through comparison, Homo habilis evolved from a species of A. afarensis in East Africa. The approximate age of the each species is close and both were found in East Africa. Also, the facial projection and brow ridge is similar on both skulls of the species. Homo sapiens neandertalensis evolved from a population of Homo sapiens in Europe. Homo sapiens (archaic) and Homo sapiens neandertalensis were both found in Western…
However, that theory has been discredited with the discoveries of early hominid remains. For example, the 4.4 million year old female Ardipithecus ramidus, nicknamed “Ardi,” indicates an anatomical connection between early hominids and our closest living relative, the chimpanzee. Some of the physical similarities described in an article posted in Discover Magazine are, “the lower part of Ardi's hip was powerfully primitive, adapted for climbing. In contrast, the upper part of the hip, the…
were waiting on 2 camels and 2 drivers who never showed up. As soon as it started to get hot they began walking to the East, across the Rift to their first border, Djibouti. In Ethiopia there is temperatures of 120 degrees fahrenheit. That day it was raining. Luckily they found and rented 2 camels. After 12 miles mohamed already wanted to give up. He explains that the scientists of Middle Awash invited them to begin walking there in Herto Bouri. Mile 0 in the Ethiopian Rift. Itid one of the…
