Hominina

In 1972 Maurice Taieb, 40, of France's National Center for Scientific Research, and Donald Carl Johanson, 34, of Case Western Reserve University and the Cleveland Museum of Natural History, discovered stone instruments going back 2.6 million years in the Afar area of Ethiopia. After two years their group made a considerably more sensational disclosure. On November 24, 1974, Donald Johanson and his understudy Tom Gray were reviewing a site named Hadar in the Afar area of Ethiopia, East -Africa when they saw a bone sticking out of the ground. They started work to reveal the bone and discovered numerous more bone sections, which turned out to be an astoundingly finish early hominid skeleton. Not a long way from their first discover, they later revealed the fossilized remainders of a 20-year-old female Australopithecus lying in a layer of silt 3 million years of age. Not at all like most different fossils of early man — a tooth here, a bone section there, incidentally a segment of a skull—this one involved a decent part of the skeleton. It was a 40% finish fossilized skeleton of a little grown-up female, matured around 25. Sections of Lucy's pelvis and thigh bones emphatically propose that she strolled upright, more than 3 million years prior. “Johanson's first revelation comprised of a couple bits of a knee bone. In the first place, Johanson thought the knee to have a place with a monkey or primate, yet it didn't appear like it had a place with such a creature (“In Search of…

Introduction The purpose of this paper is to inform the reader about the evolution of the first hominids and to look at some of the reasons that they became bipedal. From there, expand on what evidence has been found to support these hypothesis, and finally look at how these changes created both biological and geographical difference in the sub-species of hominids. This paper will detail each species in a high level overview so that the reader may gain a better perspective of what each species…

The great Ardipithecus radius (Ardi) was alive on earth around 4.4 million years go. Ardi lived in Eastern Africa where they lived in Eastern Africa and lived in the forest. Also Ardi were known as strict “omnivores”. Lastly, the brain of Ardi’s was about 300 to 1500 cubic centimeters and walked up right like humans (bipedal). Autralopithecus Afarensis (Lucy) was alive on earth around 3.2 million years ago. Lucy lived in Africa where they lived in wet and dry environment typically wooden areas…

Majungasaurus was an average sized (compared to it’s close relatives) theropod dinosaur that lived in Madagascar from 70 to 66 million years ago, at the end of the Cretaceous Period. Like other abelisaurids (members of the family Abelisauridae) , the Majungasaurus was a two-footed predator with a short snout. Although the forelimbs are not completely known as of yet, they were very short, while the hind limbs were longer and quite stocky. It can be distinguished from other dinosaurs in it’s…

Evolutionary Relationships of Hominin Species In the study of human evolution, the timeframe that a specific species appeared and lived is a very important aspect to better understand how modern-day humans developed. The oldest of the species in the chart above is Australopithecus afarensis. Australopithecus afarensis appeared roughly 3.85 - 2.95 million years ago; while it more closely resembled an ape, the evolutionary development into modern humans was beginning. Australopithecus afarensis…

Charles Darwin is very well known for his theories on evolution and most importantly his three principles of evolution by natural selection. Darwin’s first principle is that a variation exists within populations. Some examples of variations include body size, bone structure, tooth size, hair thickness, shape of the rib cage and position of the foramen magnum. In Evolution, Dr. Alice Roberts provides examples of early hominins and how their physical makeups were reconstructed by archeologists…

When looking back on the evolution of man nothing stands out more than the word “bipedalism” this is what kicked us off the ledge to start us on the path of walking upright completely and gave us the dominated figure we all have today. Now let’s take it from the beginning the earliest forms of human beings used to climb tress and would walk on the ground, this use of flexibility allowed early humans to get around in such diverse habitats and also to be able to cope with the many changing…

Current Events Assignment #7 Celimar Burgos Title: Foot fossils of human relative illustrate evolutionary 'messiness' of bipedal walking. This article explains the new study on the extinct human relative, Homo naledi that was discovered in a cave in South Africa in 2013 and recently describes last month. The discovery has to do with his feet, that although considered to be the most human-like feature of his body, besides being useful for standing and walking on them they were also good for…

The earliest members of Ursidae belong to the extinct subfamily Amphicynodontinae, including Parictis (late Eocene to early middle Miocene, 38–18 Mya) and the slightly younger Allocyon (early Oligocene, 34–30 Mya), both from North America. These animals looked very different from today's bears, being small and raccoon-like in overall appearance, and diets perhaps more similar to that of a badger. Parictis does not appear in Eurasia and Africa until the Miocene.[8] It is unclear whether…

The creature that is being examined in this experiment is the now extinct Spinosaurus aegyptiacus, a dinosaur that lived in Northwestern Africa about 95 million years ago. The Spinosaurus (fig.1) was a creature that has been estimated to be anywhere from 13 to 18 meters (43 to 60) long, weighed 7 to 9 tonnes (8-10 tons), and is agreed to be by most paleontologists the largest carnivorous dinosaur of all time. It is thought to be a piscivore, although the Spinosaurus’ diet and lifestyle is very…
