New Fossils

A new discovery of a fossil cranium and two jawbones—both 2 million years old—lead researchers to confirm that Homo rudolfensis is a distinct species. The first Homo rudolfensis skull was found in northern Kenya in 1972. The newly discovered fossil face is flat, as in the original skull. The partial jawbones look similar to the skull found in 1972 but enlarge the known variation in the skull and teeth of Homo rudolfensis. Along with fossils of Homo habilis and Homo erectus, these new specimens support the existence of multiple species of Homo in eastern Africa between about 2.0 and 1.7 million years ago.

One of the reasons why I chose this article is because a long time ago when I was a child my father and I used to go out in the woods, islands, and old Indian sites to look for fossils and arrow heads.
It was very exciting to find these arrow heads or fossils that have not been un covered in hundreds if not thousands of years. To see artifacts like this in your own eyes and to hold them in the palm of your hands is just amazing.

This relates to biodiversity and evolution very well, these fossils show how that Homo rudolfensis are a distinct species, we would never know exactly what we discovering without these fossils. With these fossils we can clearly see the difference in the humans before us and how exactly we all have become who we are through

    The tooth formula is a shorthand technique that biologist use to keep track of the teeth on a particular jaw. The formula consisted of two lines, top jaw and bottom jaw, which were used to count how many incisors, canines, premolars, and molar teeth a species had. Species A, Odocoileus virginiaus (white-tailed deer), had a tooth formula of 0033/3133. On the top jaw, the deer had zero incisor and canine teeth but have three of both the premolars and molars. On the bottom jaw, the deer had three incisors, one canine, three premolars, and three molars. Species B, Canis latrans (coyote), had a tooth formula of 3142/3143. On the top jaw, the coyote had three incisors, one canine, four premolars, and two molars. On the bottom jaw, the coyote has three incisors, one canine, four premolars, and three molars. Both the deer and coyote skull were long and skinny towards the nose and mouth. The coyote skull had a much rounder nose than the deer. Species C, Homo sapiens (human), had a tooth formula of 2122/2122. On both the top and bottom jaws, there were two incisors, one canine, two premolars, and two molars. In comparison to the deer and coyote skull, the human was an outcast. The human skull was a short distance from the back of the skull to the front. The human skull was very different in bone structure and longer in height than the deer and coyote skulls.…

    These include giant saber-tooth cats, an unidentified leaf-eating monkey, elephants with four tusks, a large water-loving relative of pigs, prehistoric giraffes, three-toed horses, pigs, and an unidentified relative of musk ox. There are also three different hyena species, all abundant and representing genera that are now extinct. The abundance of kob, roan, hippopotami, and the presence of crocodiles and pythons suggest large tracts of flooded grasslands and thin woodlands as occur along the Lake Chad shore today. Discovery of Sahelanthropus' fossils were found in the Djurab Desert of northern Chad, at a site known as Toros-Menalla (source: Intro to Physical Anthro, pg…

    Time Frame: Neanderthals diverged over 550,000 to 690,000 years ago. Other data estimates they lived between 365,000 and 853,000 years ago and 465,000 before present. Human trunk and limb bones of Homo antecessor, recovered from the Gran Dolina site in Spain have been dated at about 780,000 years old and are said to represent the last common ancestor for modern humans and Neanderthals. Phylogenetic analysis of Neanderthal mitochondrial DNA leads to a date for the common ancestor of the Neanderthal and modern humans at around 465,000 to 600,000 years ago. Archaeologists have found much physical evidence to confirm this date, such as the 0.73 Mya old fossils with stone tools and animal bones. The other date matches the movement of modern humans out of Africa and the appearance of modern traits in fossil skulls. Fossil skull traits such as high rounded skulls and small brow ridges, a vertical forehead and a pronounced chin first appear in Africa about 130,000 years ago. They then appear outside of Africa over 90,000 years ago.…

    It is still being debated to on exactly when did the ancestor of our species began to walk on two legs. One hypothesis relies on a 6-7 million year old skull of Sahelanthropus tchadensis. The skull was discovered in the Djurab Desert in Chad. Since only the skull was discovered, it is still unclear on how Sahelanthropus tchadensis fits in our evolutionary…

    Neanderthal Traumas

    Spearheaded by the Germans discovery of the skullcap and limbs, archaeologists gather information, make inferences, and use their imaginations to construct how things use to be. The conditions of the fossils let us know the kinds of conditions people/animals lived in. This can be problematic because for example, Neanderthal bones and deer bones were mixed together with some of the same marks. An archaeologist could have mixed up the bones and given the Neanderthal a characteristic of life that isn’t accurate to them. This could be the case for any fossil that isn’t easily identifiable and archaeologists have to use their “imaginations.”…

    3. Paleontology is the study of fossils, including fossilized plants and animals. Fossil are any perceived remains of a prehistoric organism, in this cause an ancient primate. The dig was lead by Dr. Biren Patel and along with a group of scientist, a partial mandible of an early primate was found in the Kashmir region of India. The fossilized mandible was DNA tested and compared to several modern organism in order to determine the closest living relation. The closest relation to the fossils DNA matched to modern day lemurs. However, this is perplexing as…

    An anthropologist believes he has excavated remains of foreign beings right here on Earth in Andahuaylillas Are they really aliens? The reason for this theory is that the two sets of skeletons discovered by Renato Davila Riquelme in Peru, South America are like no other before. For the fact that they have abnormally large skulls- almost as big as the size of their 20 inch bodies! Plus, their eye sockets are very large. They are as big as how we think of aliens would have, if they had or exist. Also, there is the fontanel on their head(the soft spot that babies are born with.) With the fact of that it makes it very unusual for them to have two large molars. This is not something that human babies would be born with. Renato Riquelme and other anthropologists in Spain and Russia who have looked over this “alien” believe that these skeletons do not look like anything that is close to any known things on Earth and think they are aliens. To figure out whether these are really aliens, they will to DNA tests from the remains of the eyeball in one of the skeletons. At the same time, other scientist have told that they believe that these strange skeletons could be a result of an old ritual of re-shaping heads. The Mayans, North American Natives, and Australian Aborigines. They would mold the in one of three ways: round, conical, or flat. Then wrap a cloth around the baby's skull for six months. If flat was what was wanted, they would place the head between two pieces of wood! It was a way to pledge loyalty to a group or display social status. How do we know for sure that these skeletons are really aliens? Could this just be a fake and used to get money or publicity? Or could this be another type of animal? We just have to wait till the experts find out!…

    Recent findings near Kenya 's Nariokotone River near Lake Turkana and Olorgesailie near L. Magadi indicate that hominids such as Homo habilis (1.8 and 2.5 million years ago) and Homo erectus (1.8 million to 350 000 years ago) are possible direct ancestors of modern Homo sapiens, and lived in Kenya in the Pre-neolithic epoch. During excavations at Lake Turkana in 1984, paleoanthropologist Richard Leakey assisted by Kamoya Kimeu discovered the Turkana boy, a 1.6-million-year-old fossil belonging to Homo erectus.…
