EVOLUTION
THE HUMAN EVOLUTIONARY TREE:
Homo Sapiens:
• Where Lived: Evolved in Africa, now worldwide
• When Lived: About 200,000 years ago to present
• About: during a time of dramatic climate change 200,000 years ago, homo sapiens evolved in Africa. It is known that homo sapiens gathered together to hunt for food and survive. Scientists use the term “anatomically modern homo sapiens” to refer to people of our own species who lived during the prehistoric times.
Homo Habilis:
• Nickname: Handy man
• Where lived: eastern and southern africa
• When lived: 2.4 million to 1.4 million years ago
• About: the homo habilis is one of the earliest members of the genus homo. It has a slightly larger brain, small face and teeth, its features are ape like, including long arms. Their name was given to them in 1964, due to this species was thought to represent the first stone-tool maker.
Homo Erectus:
• Where lived: Northern, Eastern and Southern Africa, Western Asia (Dmanisi, Republic of Georgia) East Asia (China and Indonesia).
• When lived: they lived between 1.89 million and 143,000 years ago.
• About: Homo Erectus is considered a highly variable species, spread over 2 continents and possibly the longest lived early human species about 9 times as long as our own species homo sapiens.
Early discoveries from Java and China comprise the classic examples of this species. African Homo erectus fossils are the oldest known human to have possessed modern human- like body proportions.
Homo Neanderthalensis:
• Nickname: Neanderthalensis
• Where lived: Europe and southwestern to centre Asia
• When lived: About 200,000 to 28,000 years ago
• About: They are our closest extinct human relatives. Some of their features are, large middle part of their face, angled cheek bones, and a huge nose, but their bodies were shorter and stockier than ours. They made and used sophisticated tools, controlled fire, lived in shelters, made and wore clothing, were skilled hunters of large animals, ate plants foods and made symbolic objects. They deliberately buried their dead and occasionally marked their graves with offerings such as; flowers. NO other earlier species had ever practised this symbolic behaviour.
Australopithecus Afarensis:
• Nickname: Lucy’s species
• Where lived: Eastern Africa (Ethiopia, Kenya)
• When lived: Between 3.85 and 2.95 million years ago
• About: They are one of the longest-lived and best known early human species, Lucy’s species have uncovered remains from more than 300 individuals. The lucy’s species have survived for more than 900,000 years, which is over 4 times as long as our own species have been around. They have both ape and human like traits. Their children grew rapidly after birth and reached adult hood earlier than modern humans. Their features were ape like, such as; a flat nose, strongly projecting lower jaw and a small brain. Their arms were amazingly strong and long with curvy fingers, and they also had very small canine teeth. These species adaptations such as living on trees and on ground helped them survive for almost 1 million years as climate and environment changed.
Australopithecus Africanus:
• Where lived: southern Africa
• When lived: about 3.3 to 2.1 million years ago
• About: these species have a human-like and ape-like features, larger skull housing a larger brain and smaller teeth. Featues such as; long arms and strongly sloping face that juts out from underneath the brain with a pronounced jaw. Loves climbing.
Evidence for evolution:
1. Palaeontology: palaeontology is the study of fossils, it is when simple living things are found in the old rocks and complex living things are found in young rocks. This indicates development over time or more known as evolution.
2. Geographical distribution: geographical distribution is when the earth was only on piece of land called pangae then divided into 2 which are GONDWANA AND LAURISIA. Similarities between living things of

Neanderthal Argumentative Essay

Modern Humans may always be up for debate. Scientists cite DNA evidence, location of fossils, anatomic similarities, and cultural behavior to support both sides of the argument. While the evidence is strong that Neanderthals and homo sapiens interbred, there are still many unanswered questions regarding the Neanderthals role in modern humans’ origins. The most compelling evidence that Neanderthals are ancestors of the modern human is the discovery of Neanderthal DNA in humans of non-African descent…

Structure, inexorably tied to function, also provides evidence of descent with modification. The elephant and the mammoth, for instance, clearly have similar anatomies and share a common ancestor.

Essay on Human Evolution and Homo Sapiens

Human Evolution Outline I. Evolution is directional change and is the primary way that we understand the biological history of humankind. 1. The processes of evolution shaped humans’ brains and bodies. 2. It has also shaped our capacity for culture. II. Charles Darwin’s theory of natural selection proved the most convincing scientific explanation of the variety and history of life on earth. 1. Natural selection—the mechanism of evolutionary change; changes in traits of living organisms that…

During the creation of human culture, our ancestors learned to adapt to their environments through natural selection to created our modern day genotypes and because of these factors, no homo sapiens is completely like the next. Not only are no two homo sapiens alike, but because of migration and interbreeding between continents, it is…

Evolution: Human and Common Female Ancestor Essay example

HW Human Evolution 8/1/15 Human Evolution has spanned approximately 85 million years, but Homo sapiens have only existed for the last 400,000 years. During this time we have changed our behaviors in many ways, due to changes in natural selection and physiology. This is most evident when comparing the current human skeleton to that of Lucy and Ardi's skeleton, two females who lived 3.2 and 4.4 million years ago respectively. The examples I am going to look into in this essay is the conscience…

Genetic Replacement Model

In the study of evolution, DNA is arguably the most important aspect as it shows the differences between one species and another. Almost everyone has heard the phrase “we share 99% of our DNA with chimpanzees,” and in reality, research of the human genome shows that the gene difference between humans and chimps is around 2%. Scientists have long studied the similarities and differences in the chromosomes of humans and living primates in order to determine how genetically related the two species are…
