New hominid fossil findings found in a cave located in South Africa inspire scientists to believe that Australopithecus sediba may contain information about the origins of our genus Homo. Australopithecus Sediba compared with the findings of the Genus Homo demonstrate a closer resemblance with one another. In the Malapa caves also know as the Cradle of Humankind, two individuals were discovered. This species lived between 1.977 and 1.978 million years ago. Paleoanthropologist Lee R. Berger discovered one juvenile male and also one adult female. With this discovery and examining the features, and diet of A. sediba, we will determine how much this species resembles modern humans today.
The Evidence found in the caves of Malapa was a surprise. One morning, Paleoanthropologist Lee Berger and his son Matthew arrived at the Malapa site. The young son Matthew decided to wonder off and Berger followed, minutes later as Matthew walked around he came across a fossil. Berger was thinking it was another antelope bone, but in reality it was a collarbone to one of the closes relatives in the phylogeny of human kind. In the article, New Hominin Fossils From Malapa, Alan G. Morris states, “The skeletons are securely dated between 1.95 and 1.78 million years ago, placing them at a critical juncture of human evolution; around the time of the first appearance of the genus Homo” (2). The discovery was Named MH1 being the young male skeleton and MH2 being the female. Both finding where not tampered with in any form of scavenging and preserved in limestone. For MH1 they found parts of the cranial and post cranial remains and for MH2 they found part of the mandible, upper dentition, and partial post cranial remains. The sex of the fossils was figured...

...to finding our common ancestor. According to the physical traits and age, A.sediba is a perfect candidate to the immediate ancestor to our genus Homo (choi). Examining the evidence and diet of this species, it is not enough information, More research is required.

Humanity became fascinated with the idea of evolution with the work of Charles Darwin and the Scientific Revolution. People began hunting for fossils that would prove that man had an ape derived ancestry (Weiner, 1955). After various years of searching, a piece of physical evidence was found in England that was said to confirm the theory of evolution (Weiner, 1955).This confirmation came from Charles Dawson’s discoveries from 1908, that were announced publicly in 1912 (Thackeray, 2011). Dawson was believed to have found the fossil remains of the “missing link” between ape and human evolution, the reconstructed skull of Piltdown man (Augustine, 2006). The material was found in stratigraphical evidence and animal remains that were, at the time, adequate enough to confirm the antiquity of the remains (Weiner, 1955). In 1915, another specimen, Piltdown man II, was found further proving this theory (Augustine, 2006). However, this was merely a hoax proven by fluorine relative dating in 1953; the artifacts and bone fragments discovered turned out to be altered to fit the proposed scenario (Augustine, 2006). The skull found was actually composed of a human braincase that was younger than the complimentary orangutan lower jaw (Falk, 2011). Both sections of the skull had been stained to appear to be from the same person of the same age (Falk, 2011).The perpetrator of this act was never caught and there are many theories proposed for the motive of this hoax (Augustine, 2006). Many people have been taken into consideration for this crime, such as Chardin, Woodward, Hinton, and Dawson (Augustine, 2006). Nevertheless, the evidence that proves that Dawson is guilty of this crime against anthropology is quite substantial compared to the evidence...
Chinese and Malaysian Homo Sapiens have very close features to the Neanderthal. The skull analysis of Neanderthals and Homo sapiens are usually considered more accurate if the entire skull is examined, rather than certain ...
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.

The evolution of man is constantly in question. While we are reasonably sure that modern humans and primates are both related to the same common ancestor, there is constant debate over what initially caused the two species to split into early hominids and apes. According to some, our longest and most popular theory on the division of man and ape is profoundly wrong. However, those same individuals usually offer an equally controversial theory as a substitute, one that is almost impossible to scientifically test or prove. Both the Savanna Theory and the Aquatic Ape Theory offer solutions to how and why humans evolved into bipedal toolmakers. But with enough questioning, each loses its accountability to rhetorical science.
After analyzing the remaining family group, their appeared to be a difference in size among the discovered fossils. Johanson claimed that all the remains found belonged to one species; however, other anthropologists and scientists disagreed and believed that two or more were from different species. The analysis of Lucy’s knee joint indicated that cranium, mandible, dentation and postcranial skeleton contained unique characterizes, which resembled in a large degree the ones in a human being, and also indicated bipedal locomotion.

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.
Australopithecus afarensis who existed 3.5 million years ago and a 4.4 million year old skeleton of an Ardipithecus ramidus are the closest science has come to discovering the human lineage. Shattered Ancestry an article written by Katherine Harmon discusses the remains of two hominids found within Ethiopia. These skeletal remains have created a huge controversy within the topic of evolution questioning many assumptions that have been made referencing the human lineage. The skeleton of the Australopithecus afarensis was named Lucy and was discovered in 1974. The evidence of her walking upright on her two feet essentially guaranteed her a spot in the human lineage line. Lucy was a chimplike ape that was said to walk upright making scientists believe the human ancestry was simple. The complete skeleton found in Ethiopia of an Ardipithecus ramidus named Ardi completely changed all assumptions made from scientists about the complexity of the human lineage. These remains have encouraged researches that the human line is not the only lineage to have evolved but the chimpanzee line has undergone drastic changes as well. There are many traits that researchers have always directly linked to the human lineage however since these discoveries occurred researchers are reconsidering. The recent discoveries that have shattered what has always suggested what linked a species to the human lineage have changed the certainty of whether it is possible to confidently identify the human’s last common ancestor. Majority of scientist had forgotten that there would have been many hominid species living together at one time. New theories have been suggested since scientists revealed that the foot of a hominid found called the Burtele site was found ju...

The species A. afarensis is one of the better known australopithecines, with regards to the number of samples attributed to the species. From speculations about their close relatives, the gorilla and chimpanzee, A. afarensis’ probable social structure can be presumed. The species was named by Johanson and Taieb in 1973. This discovery of a skeleton lead to a heated debate over the validity of the species. The species eventually was accepted by most researchers as a new species of australopithecine and a likely candidate for a human ancestor.

Throughout the long winding road that is human evolution; many species have helped shape who we are today. There was the early Australopithecus africanus which began to walk bipedally-upright with two feet and the Homo habilis which drastically developed the construction of handmade tools. But there is one species who is to be credited for the most critical advancements in human evolution; Homo erectus. Not only did Homo erectus advance us the most biologically, but also the most geographically.
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.
