Homo ergaster

certain similarities with tooth traits, the pelvis bone, and a broad lower chest resemble those of modern-man. Au. Sediba is a very good candidate for the ancestor to the Homo genus because of many of the similarities found in its skeletal structure. Smaller premolars, molars, as well as facial features were more similar to the Homo genus. The functional changes in the pelvis also strongly support the evolution of upright…

Louis Leakey is one of the most influential men in the world. He is a well-known white archeologist from Africa. Louis Leakey did a lot of things for Africa historically. Also Leakey won an award from a museum and organized an important event. He is an interesting person to talk about from his accomplishments to his personal life. Without Louis Leakey’s impact how would have our history turned out? Louis Seymour Bazett Leakey was born on August 7th, 1903. He was raised in Kabete—small tribe in…

The gopher tortoise is a large dark-brown to grayish-black terrestrial turtle with elephantine hind feet, shovel-like forefeet. The adult shell ranges in size of 5.9 to 14.6 inches long. It has a gular projection beneath the head on its yellowish, hinge less plastron or undershell. In comparison to females, males are generally smaller; with a larger gland under the chin, a longer gular projection, and more concave plastron. The gopher tortoise is seen as an important species in the…

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 notion that all humans are descended from a select group of hunter-gatherers based in early east Africa is called Genealogy. While humans have been around for millions of years, the behaviorally modern human emerged between 100,000 and 300,000 years ago. What changed was our ability to have abstract thought. This is what separated us from animals that followed strictly their set behaviors. The earliest evidence of these abstractly thinking humans goes to Blombos Cave. There are rocks…

This book is about Hobbits. Or at least one Hobbit. A Hobbit is kind of like a human and kind of like a dwarf, but is smaller than a dwarf and human. They are quick on their feet and silent. They do not have any kind of magic in them, though some would say that being able to quietly and quickly dissapear from sight is a magic thing. The Hobbits name that this story is about is Bilbo Baggins. Gandalf, who is a wizard, comes one day to the Shire, where Bilbo lives. Since Hobbits are usually always…

• Procoptodon Goliah (picture 1) – The Procoptodon Goliah was a part of the Sthenurines (short faced Kangaroo) This animal had a very short, deep ‘brachycephalic’ skull and a low jaw. The large Kangaroo stood at around 2 metres tall with a mass of around 200 kg. Tim Flannery an Australian mammologist, palaeontologist, and environmentalist proposed that its closest extant relative is the tiny banded hare wallaby (Lagostrophus fasciatus) this small animal only weighs 2kg in weight and is about 15…

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…

There is no mistaking the distinctive sound of a chainsaw, screaming as it bites through a hunk of wood or the bark of a tree. There are even chainsaws which are used to cut through concrete, brick and natural stone. Chainsaws are perhaps one of the most convenient power tools available, and can save a lot of time and effort in construction and felling. Although the origin of the chainsaw is debatable, it is determined that the first chainsaw was made around 1830 by Bernard Heine, a German…

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…
