to twenty millions of years ago‚ but now the time period has shifted to around five million years ago. Ardipithecus ramidus is said to have live around 4.4 million years ago. The original fossils from this species were placed with the Australopithecus genus; however‚ a new genus was designated to this group by Tim White. Tim White is an anthropologist and co-author of Geological Study of America Bulletin in which this distinction was first stated. This hominid is different from its predecessors

Along with a big brain‚ opposable thumbs‚ bipedalism is one of the characteristics that makes the human species unique. The dictionary defines bipedalism as “a condition of using two feet for standing or walking”. Walking on two legs allowed our ancestors to see better‚ have freed up hands‚ and eventually become erect. Bipedalism is one of the initial driving force of the human evolution. It is still being debated to on exactly when did the ancestor of our species began to walk on two legs. One

large‚ portruding ridges over either eye. Another important being in the human timeline is Australopithecus africanus. Many scientists believe that it is the next in the sequence leading to man‚ however‚ a few believe that it belongs to a lineage on its own. A. africanus fossils have been dated back to the time period between two and three million years ago. It had a greater body size than A. afarensis‚ and a skull volume ranging between 420 and 500 cm3. It averaged a little higher in

Sahelanthropus tchadensis has a skull with an elongated shape with a relatively short‚ vertical face‚ which is set high relative to the skull vault. The eyes are set far apart from each other and have a very large continuous bony brow ridge above them. Examination of the lower jaw reveals that Sahelanthropus had a total of thirty two teeth‚ which is common in all Old World monkeys‚ apes‚ and humans. The foramen magnum (where the skull opens for spinal cord passage) is positioned forward and oriented

As the years have past‚ advancements in engineering and science have improved people’s lives dramatically. The result of this has placed an emphasis on the thought that science can never be wrong and that we all should blindly accept what the majority of the scientific community says. This includes the theory of evolution. Sadly‚ “Christians” are becoming more and more accepting of this belief. Theistic evolution is rapidly becoming a widely accepted idea in Christian circles. It is even being taught

There is a theory that humans descended from an earlier‚ lower form of life. There is an assortment of evidence that shows that all living creatures on Earth descended from a common ancestry. Evolution doesnt discriminate against humans. It is believed that we too are a product of an earlier predecessor. The similarities in all life are evident if you consider that every form of life builds from the same building blocks--20 essential amino acids‚ four nitrogen bases‚ and simple sugars. Each of Earths

The purpose of this experiment was to observe the process of human evolution by observing similar features of the Pan troglodytes‚ Australopithecus afarensis‚ Homo erectus‚ Gorilla gorilla‚ Australopithecus boisei and the‚ Homo neanderthalensis in comparison to those of the Homo sapien. According to Darwinism‚ the species that had the most traits in common with the Homo sapien must be the most related while species with the least traits in common with the Homo sapien were the least similar. For example

I. Introduction Planet of Life: Apes to Man is narrated by Stacy Keach and it was originally produced and presented by the Discovery Channel. This series shows us about the history of evolution on this planet and each episode has a separate chapter in the biography of the world. This series also shows us that one group of primates moved onto plains where they evolved the ability to stand upright. They used computer and technology to examine the evolution of humans so that the series will be clear
