Evolution is a process in which living organisms develop across a period of time (Bourrat, 2014). It also shows how one species is genetically linked to another or how it has common attributes to other organisms (Bourrat, 2014). Throughout their course of life each species will go through a process known as natural selection. Natural selection serves as an ability to pass on better genes on to the offspring in order to maintain an increasingly higher genetic code (Bourrat, 2014). Evolution in most

Humans are a complex organism. The theory of evolution suggests that we all came from a single ancestor and have evolved over millions of years to create our species that lives to this day. But what is evolution? Who did we all evolve from? What makes us different than this ancestor of ours? What is Evolution? Evolution is a process that results in heritable changes in a population spread over many generations. Scientist Charles Darwin believed that natural selection was one of the main reasons

Background and goals The conditions in which bipedal locomotion emerged are still unresolved. However they are all closely dependent on environment reconstructions. This project will contribute to the scientific community's understanding of the environments of the earliest Australopithecine. Australopithecus anamensis is the earliest species of the genus and the first indisputably bipedal hominid. According to paleoecological analyses (isotopes, fauna, soils, etc) (2,3), these hominids were generalists

The Earth has never stopped revolving ever since it had existed. About 2.5 billion years ago during the Proterozoic Eon to the Cenozoic era in which we live in today, a single-celled organism was able to evolve into many cells, which led to dinosaurs, mammals, primates, and many other organisms. Not only did the animals evolved, our ancestors did too! They had passed on their genes and traits as well as new ones to create the human-being we are today. We didn 't start out like this. Millions of

Conflict Between the Multiple Theories of Bipedalism Why early hominins, the evolutionary ancestors of Homo sapiens, originally became bipedal is a source of contention among many physical anthropologists both today and in the past. There are multiple theories and models that have surfaced over the years to explain why these early hominins evolved to become bipedal, but because there is limited fossil evidence and very few intact pelvises from that time period to study, it’s difficult to conclusively

The Basilosaurus isis was a large marine mammal that lived around 38 million years ago in the Eocene era (Fahlke, 2012). Due to its enormous size, about 16 meters or 48 feet, this animal was able to prey on other large animals, specifically one closely related to it, the Dorudon atrox (Fahlke, 2012). Evidence of this was found by the analysis of Basilosaurus spp. teeth and comparing them with the bite marks found on D. atrox skulls (Snively et al., 2015). From these tooth marks, it can also be

The most common way to differentiate between modern humans and apes is human’s bipedalism. There are two fossil species available to the study of Ardipithecus: Ar. ramidus and Ar. kadabba (Gibbons, 2009). There is much greater evidence to analyze Ar. ramidus, a hominine that lived from the Late Miocene to the Early Pliocene (Gibbons, 2009). The 1994 discovery of A. ramidus, commonly referred to as Ardi, included “125 pieces of her skeleton” such as “pelvis, hands, arms, leg, and feet” (Gibbons, 2009

It is clear that early possible hominins discovered, Sahelanthropus, Orrorin, and Ardipithecus, are tied to modern humans, and the ancestors of other infamous bi-pedal species. But figuring out how it all ties together is another conundrum. From my research and attained knowledge from class I believe that Sahelanthropus was the first to come, followed by Orrorin, and then Ardipithecus. One of the biggest factors to have brought me to this decision is the existence timetable. Sahelanthropus was thought

While time travel still remains elusive to us, scientists have been able to discover things about our past as a species that were practically inconceivable over 150 years ago when Charles Darwin released his book entitled The Origin of Species. They have especially uncovered many pieces to our still incomplete puzzle over the past 20 years so that we now have a nearly complete idea of how our species Homo sapiens came to be. This story of our history includes dozens of species’ and hundreds of fossils

For centuries humans have been left wondering how they were made and where they came from. Many found hope in the name of god. They had no choice to believe that they were created by god, different cultures having their own beliefs and ideas. However, in the modern era there is a different ideology, people have started to think logically and science has come a long way. It is now believed that evolution has resulted in the changes on planet Earth and human kind was not just simply created by a ‘God’
