Recommended: The origin and spread of modern human

Throughout history, humans have asked many questions in regards to our own beginnings. Religion and science have examined what makes us who we are, and have tried to answer the enduring question of our own modern origins. Scientifically, theories are still debated as to when, where, and how modern Homo sapiens came to be what they are today. There are two major theories that now dominate the discussions of experts in the field of biological anthropology: the “Out-of-Africa” model and the “Multiregional” model of evolution. Stringer and Andrews argue that genetic and paleontological evidence supports a more recent Out-of-Africa model as opposed to a more drawn out Multiregional method that also incorporates gene flow (1263). In contrast, Wolpoff, Hawks, and Caspari claim that the Multiregional model is misunderstood, and clearing up discrepancies could bolster support for this theory instead (129). Pearson notes that while people like Wolpoff et al defend the Multiregional model, archaeological evidence seems to show that likely no intermixture between modern Homo sapiens and other archaic hominins happened during the spread of early Homo sapiens out of Africa (145). It is easy to see that the debate lingers onwards with an end not clearly in sight. This paper will further examine the arguments asserted by these authors and identify their core arguments, the data they use to support their arguments and determine which paper is the most convincing of the three.
According to Stringer and Andrews, the Out-of-Africa Model suggests that there is a fairly recent common ancestor that shares many of the anatomical characteristics displayed by modern Homo Sapiens (1263). This version is more parsimonious with regard to the fact that it ...

...uestion, we will be able to extend research about why humans came from where they did as well as know where to expect the fossil record to lie. Without debates like this one, the research community could lay stagnant, but instead these debates promote new motivations to answer the ever-human desire to know.

  • Proof that Humans Interbred with Neanderthals

    1346 Words  | 3 Pages

    Over the last few hundred years, more and more has been added to the world’s fossil collection, fossils from all over the world. New theories have been created and old theories have almost been proven about the evolution of man. For example, we have proof that different species of man existed with certain types of DNA sequences and instincts, some we may not have anymore, or some that other species did not have back then. Even though it is subjected to much debate, one of the most widely accepted theories however, is that Homo sapiens interbred with the slightly more primitive species of man, the Neanderthal.

    A study performed by Martin Hausler and Peter Schmid of the University of Zurich, Switzerland, appeared in the October 1995 issue of Journal of Human Evolution, igniting controversy over the 1974 Australopithecus discoveries in Hadar, Ethiopia. The most famous of the Hadar specimens is the 3-million-year-old skeleton, “Lucy,” who was recovered by paleoanthropologist, Donald Johanson. In his article, Shreeve presents the methods and findings of Hausler and Schmid’s study as well as some counter arguments from other scientists in the field.

  • Savanna Theory Versus Aquatic Ape Theory of Human Evolution

    1286 Words  | 3 Pages

    The evolution of man is constantly in question. While we are reasonably sure that modern humans and primates are both related to the same common ancestor, there is constant debate over what initially caused the two species to split into early hominids and apes. According to some, our longest and most popular theory on the division of man and ape is profoundly wrong. However, those same individuals usually offer an equally controversial theory as a substitute, one that is almost impossible to scientifically test or prove. Both the Savanna Theory and the Aquatic Ape Theory offer solutions to how and why humans evolved into bipedal toolmakers. But with enough questioning, each loses its accountability to rhetorical science.

  • Lucy, discovered by Donald C. Johanson and Tom Gray, is Our Oldest and Most Complete Human Ancestor

    In 1972, a group of researchers led by Donald Johanson, founding director of the “Institute of Human Origins” of Arizona State University, sets out to discover a hypothesized human ancestor, Lucy, in the Hadar Formation in Ethiopia. Donald Johanson’s group hypothesized the existence of a biped human ancestor, with the great ability to walk upright like humans, which of Lucy having a relatively small cranial capacity like that of an ape. This creature, Donald Johanson hypothesized, would be a “missing link” between the apes and humans, and prove that the populated humans developed the ability to walk upright before developing higher intelligence, which was opposed to the common b...

  • Human Evolution: Ideas and Opinions Related to Evolution

    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...

  • Neanderthals and Homo sapiens

    2241 Words  | 5 Pages

    This paper has shown how Homo sapiens had several advantages over the Neanderthals including better diets, better tools and just better luck. The Neanderthals could not survive the harsh climates they were thrust into and eventually died out. In this paper I looked at how Homo sapiens and Homo neanderthalensis had co-existed but the disappearance of the Neanderthal ius due in some part to the appearance of the more culturally advanced and genetically superior Homo sapiens. Although the How and Why of how Neanderthals went extinct, it is clear that Homo sapiens had a part in their demise. In the last one hundred and fifty years that we have been studying humans we have seen them come from savage brutes, to Homo sapiens respectable contemporary. If we had not gotten lucky in the past, Neanderthals could be studying us today.

  • Australopithecus Afarensis

    608 Words  | 2 Pages

    The species A. afarensis is one of the better known australopithecines, with regards to the number of samples attributed to the species. From speculations about their close relatives, the gorilla and chimpanzee, A. afarensis’ probable social structure can be presumed. The species was named by Johanson and Taieb in 1973. This discovery of a skeleton lead to a heated debate over the validity of the species. The species eventually was accepted by most researchers as a new species of australopithecine and a likely candidate for a human ancestor.

    In class we watch a clip called “Journey of Man” and basically the all over view of this movie was about a man named Spencer Wells and his team of scientist researching for approximately 15 years of investigating to find out our family history. They believe that they have discover some life changing information. They had this discovery for a while now but that needed time to gather up all of the facts from their research. This information that they have could transform our view on the world. They have revealed some type of time machine that has allow them to see back in ancient history. For that past ten years this man and his team have been using this time machine to gather all types of different information about the past history. This information came for just once source, blood. Many people views it as and gift from the past, but to scientist it carries the past and has a unique story behind it. A time machine hidden within us.

  • Interbreeding Between Neandertals and Modern Humans

    1344 Words  | 3 Pages

    The human archaeological record is a long and undefined story that may be the most complex question researched today. One of the big questions in human history is the disappearance of the Neanderthal people from the archaeological record around 30,000 BP. While for thousands of years Neanderthals and Anatomically modern humans crossed paths and perhaps lived in close relations, we have yet to really understand the degree to which they lived together. My hypothesis is that these two hominids, Neanderthals and Anatomically Modern Humans, interbred exchanging genes after Modern Humans dispersed from Africa and creating like cultures and material remains. The differences between Neanderthal and Modern humans are not only physical but also genetically evolved and this research will determine an estimated amount of admixture between the two groups.

  • How Humans Developed: The Homo Sapiens

    1823 Words  | 4 Pages

    “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.

  • Analysis Of Sapiens: A Brief History Of Humankind

    1036 Words  | 3 Pages

    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.

    The evidence for human evolution begins with the australopithecines. All the australopithecines were bipedal and therefore possible hominines. In details of their teeth, jaws, and brain size, however, they modify enough among themselves to be divided into five species: Australopithecus anamensis, A. afarensis, A. africanus, A. robustus, and A. boisei. Genus Homo are also divided in five different spices: Homo erectus, H. habilis, H. sapiens, and H. sapiens sapiens.
