Fossils And Genetic Evidence Of Human Evolution In Africa

896 Words4 Pages

The process by which humans originated from apelike ancestors are known to be called human evolution. Evolution occurs when there is a change in DNA. Over the years, human evolution has been a big question of our society. Evolution doesn’t just happen to a single individual; it happens to population over a long period of time. (Potts, 2016) C. Loring Brace and Milford Wolpoff hypothesized that only one species existed earlier in life, that were not yet homo sapiens (Lewin, 1984), which brings about the question: how did we change into such creatures overtime? Fossils and genetic evidence showed proof that millions of years ago, human evolution formed in Africa. There we discovered the birth of our first ancestors. Early primates left Africa …show more content…

Vast majority of researchers today acknowledge the fundamentals of evolution; however, they all have differing views on how development actually occurred. Despite the fact that similarities amongst man and other animal structures were found by Linnaeus, the three main theories came about. These theories include: Darwinism,
Lamarckism, and Synthetic theory. Charles Darwin theory of Natural selection (survival of the fittest), describes how a species can accumulate changes and adapt to an environment, and also pass traits onto its offspring. Lamarckism states that characteristics can be passed on to its offspring; whereas the Synthetic theory includes variations or transformations of genetic information. Even though many people stand with the belief of human evolution, some people do not, due to the fact that the bible denies this theory by stating that God created all organisms in their present form. Research studies shows that Reverend Samuel Wilberforce agreed with the works of the bible, that life had no explanation. (Regal, 2004) On the contrast, Charles Darwin was a naturalist, whom contributed a lot into the science of evolution. Darwin allegedly claimed that species were not just created by God, they were made naturally. (Sulloway, 2005) In his book, The Origin of Species, Natural selection and variation explains his concept of …show more content…

Human evolution was also shaped by the changes of the climate. When East Africa began to dry out, this drove homo sapiens to travel on their two legs. The theory of climate change affecting human evolution rests on paleoanthropologist, Rick Potts. (Slezak, 2015) Some homo sapiens adapted to cold weather and some adapted to hot. Homo neanderthalensis, nicknamed Neanderthals, are primates that associate to modern humans. These species were extinct around 40,000 years ago. In contrast to modern day humans, they were shorter and a bit heavier built, which made it easier for them to adapt to cold weather.

Neha Chandran SQ3R Chapter 1 Analyze the first humans. About three to four million years ago, the first humans classified as hominids lived in Africa. Australopithecines were bipedal and were able to make simple tools out of stone. Louis and May Leakey discovered a hominid that they named Homo habilis. These hominids were the first to make tools.

Ancestors in Our Genome, addresses the continuingly advancing disagreement upon whom our closest ancestor is within the great apes, described as the hominoid trichotomy debate. The author, Eugene E. Harris examines many different sources of evidence within the book, and with the help of improvements in biological and DNA technology he helps discover who our closest ancestors were. Also when we were first separated from them and how the separation took place. Although there have been many recent advances in technology, a large number of unanswered questions are still a mystery within our genome and evolution from the great apes. Chapter one discusses the debate of morphology - studying fossil evidence of the great apes - versus molecular

Between 100,000 and 50,000 years ago, the human race created the “Great Leap Forward”. Human development was dominant in some countries than others. The animals most common to the human race are gorillas, bonobos, and chimpanzees. Around 11,000 B.C. were the first sightings of villages to be seen. Fossils show that the human race changed about 2.5 million years

The article I have chosen was written by Helen Pilcher and is about evolution of creatures, especially for primates. However, until now, what do our very first primates were like still remain mysterious as we do not have sufficient information and evidences which are 60 million years ago. Yet, we still cannot deny that evolution occurs in creatures. No matter for humans, animals or plants, all of them will make changes because of their living habits and environment in order to survive. In this article, the author explains everything clearly about the primate evolution was taken around million years ago and ancestors are a small and nocturnal creature.

Climate change influenced nonhuman primate evolution in a variety of ways. Around 55 mya, a serious period of global warming occurred just as euprimates were beginning to appear. Our book discusses how this rapid temperature increase created tropical weather conditions all across the globe. As a result, new habits were created and there was "an adaptive radiation of modern-appearing primates, the euprimates" (Larsen 260). In other words, the high global temperatures paired with the humidity let to the spread of tropical forests.

Chapter 1 Summary: 1. Chapter one is about the starting of human life. Diamond starts the chapter off by explaining Homo erectus and how humans developed from apes to Homo sapiens. The chapter further explains how humans split off into sections of the world, by starting out in Africa and spreading to continents such as Eurasia and Australia/New Guinea. The main discussion of chapter one is how the humans developed differently between different areas of the globe, but all originated from one place.

The physical nature of a primate body as wells as its movement is a unique factor in the animal kingdom. 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.

It is often assumed that in this contemporary society issues pertaining to race have been kept to a minimum, but the true reality is that racism is present in current day America now more than ever. In the novels, The Time Machine by H.G. Wells and Dune by Frank Herbert, there are underlying tones of classism, parochial thinking, and ignorance which lead to the common themes of racism and division within societies, which directly draws parallels to modern American behaviors. Authors Wells and Herbert emphasize the negative human conditions through their characters within their society, stressing the notion that the current common human behavior will ultimately lead to a bigger divide amongst races and will further create a dystopian lifestyle where humanity and the environment will cease to exist. Classism is a prominent theme throughout the novels Dune and Time Machine, it is evident that through people’s preconceived notions about certain races, they stereotype minority groups to be associated with working class, which reflects on how classism and racism are heavily linked together.

Deborah Swarthout Modern Man and Neanderthals WCCCD-Fall 2017 Modern Man and Neanderthals: Where did they go? It has long been thought that modern man evolved from the Neanderthals. Although we have many similarities, the most recent studies suggest that modern man actually co-existed alongside the Neanderthals and interbred with them to create the modern man we know today. Neanderthals or Neandertals (Homo Neanderthalensis) are considered to be our closest extinct human relatives.

Introduction The theory of evolution has been discussed, evaluated, and researched many times since the theory was first brought to light. Darwin’s theory of evolution is said to be divided into two parts, common decent and natural selection (Bouzat, 2014). Many research papers agreeing with Darwin’s theory comment on the diversity of a species and how they have descended from one common ancestor. Natural selection is a process in which species that are better adapted to the environment tend to survive and reproduce (Dictonary.com).

“According to the Death Penalty Information Center, most death penalty studies that look at race indicate that a defendant is more likely to receive the death penalty if the victim is white, rather than black” (Butler). Paul Butler emphasizes that the death penalty is unconstitutionally cruel because the reason why people are sentenced to capital punishment is due to their race. A person’s race is focused more on a conviction for the death penalty than the actual crime itself. As a result, this causes the death penalty to be unacceptable in society. At least eighteen states have already ended capital punishment since early 2014; however, some states have not and continue to have it because they don’t see it as cruel.

In the article First of Our Kind, Kate Wong explains why the fossils found by paleoanthropologist Lee Berger could challenge current notions about human evolution. Geologists dated the fossils to be 1.9 million-years-old which makes this species younger than Australopithecus africanus and contemporary with Homo habilis. This, along with the mix of Homo and Australopithecine traits, led Berger to the theorize that this species was a descendant of A. africanus because of its location, and ancestor to Homo ergaster because of the Homo traits. Berger 's theory would thereby toss A. afarensis and H. habilis into the junk drawer where hominid dead ends are kept.
