Recommended: Evidence of evolution Essay

xplain how each of the following provide evidence supporting evolution. Provide at least one specific example of each.
a. Transitional fossils: Transitional fossils are the missing links between animals we see today and their ancestors. During evolution, many animals developed adaptations and evolved over time to be better suited for life on Earth. An example of a transitional fossil is Pakicetus, which is an early ancestor to today’s whales. (Berkeley)
b. Biogeography: Biogeography is the study of geographic distribution of animals. Species normally live close to others with a genetic relationship to them. An example of this is marsupials. Kangaroos and other marsupials are more dominant in Australia than in other places around the world. (book)
c. Comparative anatomy: Comparative anatomy involves observing body structures of today’s organisms to determine their evolutionary history. An example of this would be that bats, porpoises, and humans all …show more content…

Compare and contrast each of the following hominins to modern day humans. Describe similarities and differences with each.
a. Sahelanthropus tchadensis: Sahelanthropus tchadenis lived 7 to 6 million years ago, they are the oldest known hominin. They had human and ape features. There is a remaining cranial material which indicates they had small brains, even smaller than chimps. The ape features were a sloping face and an elongated skull. The human like features were canine teeth, middle part of the face, and a spinal cord opening underneath the skull. (5)
b. Australopithecus afarensis: There are remains of a 3.2-million-year-old female nicknamed Lucy. She belongs to the Australopithecus afarensis group. Lucy displayed a key human trait; upright walking posture. Although they walked like humans they were not as developed as humans today. They were short, had small heads, and brains that are one-third the size of a human’s brain today. The offspring grew quickly and reached adulthood earlier than today’s humans.

With a larger brain, they were able to make better decisions when it came to searching for food. Around 1.5 million years ago, a new variation of the hominid emerged. They were named Homo erectus and were able to make more sophisticated tools. They were the first hominids to leave Africa and travel to parts of Europe and Asia.

Similarities Between Neanderthals And Modern Humans

74 Words | 1 Pages

Although Neanderthals and modern humans are similar, there are still physical differences due to evolution and the environmental needs of each species. First, there is no chin present in Neanderthals, while there is one in modern humans. Second, the ridge above the eye brows is more pronounced in Neanderthals. Next, the nose is larger in Neanderthals. Finally, Neanderthals were shorter and more heavily built than modern humans, having broader ribcages, hips, and shorter

Chicago World's Fair Research Paper

As was discussed in the previous paragraph, this bipedal aspect is what differentiates us, hominids, from modern apes. However, under the context of hominids in general and modern humans, it is this very trait that allows for us all to be categorized under the same label—hominids. Along the same lines as bipedal, another similarity between the two would be our arched feet—a characteristic that is unique to hominids, as it allows for standing and walking upright to take place. Both of these similarities—bipedal and arched feet—can be evidenced in the “Turkana boy” photo as well as the photo labeled “hominid/ape footprints.” As for differences, however, despite being quite similar in many ways, there are still a number of differences between hominids and modern humans, one of them being the size of our brains.

Essay On What Are Some Key Features Of Family Hominidae

542 Words | 3 Pages

Humans evolved from these pre-human primates around 3 and a half mya. The primates that evolved into humans 3 and a half mya such as the Ardipithecus robustus portrayed many human like features as they were the last species of primates to evolve before humans were introduced. The primate displayed two arms, two legs, a head, jaw, neck, eyes, mouth etc. This species was as human as primates got because next up was the species Homo habilis which appeared much more human like than his ancestor. Still walking on his hind legs and chewing his food in his mouth and seeing through his

There has been continuous change through locomotion and body configuration throughout each grades of primate evolution. In this essay I will be discussing the modifications in time as well as theories in each grade of primate. This research paper will try to elaborate on the evolutionary modifications and some of the theories that have been proposed for these changes throughout our and other primate evolution. With time primates development was due to environmental changes.

Evolution Of The World's Most Famous Human Fossils Sparknotes

1040 Words | 5 Pages

Imaara Zuhaire May 1, 2023 Introduction to Human Evolution Professor Robert Scott Fossils are an important tool to help tell stories about the history of the world and humankind. Fossils help answer important questions such as how humans evolved over time, what their lifestyles and diets looked like or where they migrated from. Anthropologists see fossils almost as celebrities because of their rarity. This importance is portrayed through the lens of Lydia Pyne in Seven Skeletons: Evolution of the World’s most Famous Human Fossils. Seven Skeletons is an exploration of scientific and cultural significance of human skeletons throughout history.

The skull showed characteristics of both apes and the early ancestors of humans, leading scientists to believe that Eoanthropus dawsoni, was the missing link between apes and modern day humans. The skull was the same as a human skull in many ways, however the cranial volume was much smaller than that of a human. Another major difference which lead to the Eoanthropus dawsoni being labelled a fake

Essay On Bipedalism

2173 Words | 9 Pages

The most characteristic physical features of a hominin is considered to be bipedalism and an upright posture. Humans, also referred to as hominins, differ from other hominids when comparing these features. It is the features that make us unique to other hominids. Bipedalism has gained hominins many advantages over quadrupedal hominids. The change of the skull in hominins is due to bipedalism and an upright posture which has made therefore helped hominins advance further than quadrupedal hominids.

Original Flood Myth: The Evolution Of Humans

713 Words | 3 Pages

In 2004 researchers found human genes that control the size and complexity of the brain have undergone rapid evolution in humans and that mammals and other non-human primates had not evolved in this manner. Homo erectus were the first of the hominins to emigrate from Africa and from 1.8 to 1.3 million years ago, this species spread through Africa. The homo sapien (humans) originated in Africa during the last 250,000 years and spread from Africa during the last 60,000 years. Neanderthals are of the homogeneous species and are not human ancestors. Although, the difference between humans and Neanderthals when compared to great apes is small.

To determine similarities and difference between the evolution of a species, evidence is shown in the bone structure of fossils and therefore allowing comparisons to be made. Scientist have used fossil evidence to produce theories, such as Darwin’s theory of Evolution. The Phylogenetic tree is a branching diagram which categories animals into different orders, indicating the differences within a species. Overall it is claimed that species from the same order of classification share genetic information from a common ancestor.

BIOLOGY RESEARCH ESSAY There is great speculation around evolution. As we are continually in the process of discovering the history of human beings, there are many questions surrounding this topic. One very interesting question is why ancient ancestors of homo-sapiens evolved to walk upright like we do today. An apes’ DNA is astonishingly similar to that of a humans, (97% the same) and yet, our bones’ shapes and structure are very different.
