2) The concept of descent with modification, or evolution, has a great deal of evidence in its support. Indicate the major types of evidence.
Some of the major types of evidence that supports evolution are from the similarities that organisms living on distant locations have to one another. Charles Darwin logic when he summarized his findings of five year collecting evidence around the world while he was on the HMS Beagle. Darwin noticed the similarities between animals and plants on the same continent though they were diverse.
On a molecular level protein structures and gene sequences is used to determine the evolutionary relationship with the random mutations in our genes. Our genes contain instruction to create protein which creates out physical traits. It is those traits that are molded by natural selection. It determines how well the individual organism can live in changing environments and the chance to have as many offspring as possible.

Dr. Goodall is a well-known British primatologist who has discovered a substantial amount about primates in her many years of research. She has written numerous books, including one that we will be going into depth about called, “Through a Window.” Her book contains personal experiences, research findings, and even pictures to help the readers visualize her scientific breaking moments from her thirty years with the chimpanzees of Gombe. She states that there is are minor differences, and several similarities between humans and the chimpanzees. We will discuss these differences and similarities through their social behavior, intellectual ability, and emotions. To conclude, examine Goodall’s research to adopt what her findings can tell us about our early ancestors, and whether or not her study coincided to the steps of scientific methodology.
Australopithecus afarensis who existed 3.5 million years ago and a 4.4 million year old skeleton of an Ardipithecus ramidus are the closest science has come to discovering the human lineage. Shattered Ancestry an article written by Katherine Harmon discusses the remains of two hominids found within Ethiopia. These skeletal remains have created a huge controversy within the topic of evolution questioning many assumptions that have been made referencing the human lineage. The skeleton of the Australopithecus afarensis was named Lucy and was discovered in 1974. The evidence of her walking upright on her two feet essentially guaranteed her a spot in the human lineage line. Lucy was a chimplike ape that was said to walk upright making scientists believe the human ancestry was simple. The complete skeleton found in Ethiopia of an Ardipithecus ramidus named Ardi completely changed all assumptions made from scientists about the complexity of the human lineage. These remains have encouraged researches that the human line is not the only lineage to have evolved but the chimpanzee line has undergone drastic changes as well. There are many traits that researchers have always directly linked to the human lineage however since these discoveries occurred researchers are reconsidering. The recent discoveries that have shattered what has always suggested what linked a species to the human lineage have changed the certainty of whether it is possible to confidently identify the human’s last common ancestor. Majority of scientist had forgotten that there would have been many hominid species living together at one time. New theories have been suggested since scientists revealed that the foot of a hominid found called the Burtele site was found ju...
Many discoveries have been made that give more and more clues to the history of life on earth. Paleontologists find artifacts throughout the world that not only answer many questions but also raise many new ones. A topic that is still a mystery today is the origin of man. Scientists often debate over where man originated from and who some of his prehistoric relatives were. Some people think that all men are related, and that there has been inter breeding between different groups of men. (I.e. the Neanderthals from Eurasia at some point bred with the homo sapiens of Africa.) Others believe that certain groups of men evolved in a completely different time period in a completely different place.
Human characteristics have evolved all throughout history and have been manipulated on a global scale through the use of science and technology. Genetic modification is one such process in which contemporary biotechnology techniques are employed to develop specific human characteristics. Despite this, there are a countless number of negative issues related with genetic modification including discrimination, ethical issues and corruption. Hence, genetic modification should not be used to enhance human characteristics.
5.) Primates and all mammals share a series of characteristics such as: body hair, long gestation and live birth, mammary glands, different types of teeth, ability to maintain a constant body temperature, increased brain size and a considerable capacity for learning. Scientists created a special order called primates, because they share many characteristics unique to their order: a tendency toward erect posture, a flexible, generalized limb structure, hands and feet w/ a high degree of apprehensibility, retention of 5 digits on hands and feet, an opposable thumb, nails instead
There is great debate over the concept of primate evolution. Some research supports the idea that evolution occurred linearly as a continuum while other research supports the idea that fossils found to date should be separated into individual species. Through morphological, and geological evidence this paper explores this topic and provides concise arguments to further develop the understanding of human primate evolution.
Humans and non-human primates have many behaviors and characteristics in common. All humans and non-human primates also share physical and beha...
The debate of human evolution being fact or fiction has been around for hundreds of years. Evidence of human ancestry has been found in many parts of the world and these fossils found have been proven to be human. The parts of the world include Eurasia and Africa. Although fossils are found in Eurasia, the human ancestor the Hominoidea has been traced back to the Miocene epochs, which were 23 to 5 million years ago. The Hominoidea is a super-family, which contains many species that are existent today including, gibbons, orangutans, gorillas, chimpanzee, and humans. Throughout history humans have migrated and evolved, as evolution occurred humans became more technologically advanced, while the other species in Hominoidea remained the same. Also, the lineage of the human, which had moved to Eurasia 1.8 million years ago, was in fact not completely human, but has become extinct. Human evolution is a topic that seems stretched, but the humans millions of years ago aren’t completely different from modern day, since the ancient ancestry has proven the logic to make tools for survival. Human evolution is a never-ending topic, is it myth or factual, and it will be debated for centuries even with the proof it happened (Robinson 2009).
When and why did Homo Sapiens begin to grow into a thriving population that have produced both cognitive and technological advances? No one knows for certain and because of this question countless amounts of people have decided to become anthropologists. Anthropology is defined as, “the study of human beings and their ancestors through time and space and in relation to physical character, environmental and social relations, and culture(Merriam-Webster). Despite all of the time and effort that anthropologists have put into discovering the correct response, the answer to this question is constantly changing because population, cognitivity and technology are constantly changing too. One way to determine how these factors affect Homo Sapiens is by studying past societies. The development of technology expanded rapidly in the Upper Paleolithic era. The technological and cognitive advances made by the growing Upper Paleolithic people changed their lives for the better and allowed them to adapt to their environment in innumerable ways.
“The scientific study of how humans developed did not begin until the 1800s in Europe. Until that time, people relied on religious explanations of how humans came into existence. Starting in the 1500s a scientific revolution began to sweep Europe. Thinkers started using scientific methods and experiments to try to better understand the world and the creatures living in it. Eventually these methods were turned to the question of human origins” (The Nature Of Human Origins, 1). Earth made it possible for species to change over time because Ancient Earth provides ability to plenty of time.The Homo Sapien a is very complex creature. The species started off very simple by living in caves and surviving with little food and then later evolved into a species that were able to do many more complex things. The first species was Sahelanthropus tchadensis They were one of the most simple humans in that time period and on. They had very small skulls compared to Homo Sapiens today and their motor skills were just the same. We have evolved and changed for the better both mentally and physically. The Evolution of Homo Sapiens started off simple, such as the Neanderthals, and now we are the most advanced species to ever walk the planet so far.
Are we still evolving? How do humans and apes share a common ancestor? Modern human species or Homo sapiens have shown great similarities in the physical and genetic makeup to another group primates species, the apes. Both organisms share a common ancestor dating back eight to six million years ago. Evolution means change over time. Human evolution is the process by which humans have emerged from apelike ancestors. Through sequences of mutations, genetic drift, migration, and natural selection and technology we are able to observe the amazing amount of similarities and diversity of humans to other living organisms. Humans have roamed the earth for about six million years. At least, that is from when the oldest human ancestor was discovered.
Charles Darwin also showed how new species were created on the acts of evolution. It is easily explained by having big differences from the effect of natural selection, which were considered to be new species. So back in the beginning, before the effects of evolution had occurred there was just one specie, which evolved to make the species that we know today. So somehow all species are somewhat connected. The basis of what Darwin was proving was that life on Earth is simply the result of billions of years of adaptation to the changing environments. That is why certain species can only live in certain climates. This can be explained with the color of your skin, or the growing of plants.
The DNA code, that forms our genes, was the missing key for Darwin to understand how things evolved. DNA does not stay the same, it can be changed by mutations. Mutations are needed to generate variations. Without the mutations things would stay the same generation after generation. Pieces of DNA called a switch can turn certain genes on or off. Genetic Switches helps to create mutations which are sometimes responsible for an entire new species spawning from another. This is how a snake can evolve from a four legged animal, and how a whale 's front flippers has bones inside that resembles
Author Yuval Noah Harari has a unique way of reviewing the past fourteen billion years in his monograph Sapiens: A Brief History of Humankind. His intention for writing this book is mainly to bring up the conversation of the human condition and how it has affected the course of history. In this case, the human condition coincides with the inevitable by-products of human existence. These include life, death, and all the emotional experiences in between. Harari is trying to determine how and why the events that have occurred throughout the lives of Homo Sapiens have molded our social structures, the natural environment we inhabit, and our values and beliefs into what they are today.
Evolution is the complexity of processes by which living organisms established on earth and have been expanded and modified through theorized changes in form and function. Human evolution is the biological and cultural development of the species Homo sapiens sapiens, or human beings. Humans evolved from apes because of their similarities. This can be shown in the evidence that humans had a decrease in the size of the face and teeth that evolved. Early humans are classified in ten different types of families.
