“The Origin of Modern Humans” by Roger Lewin as my book to read for my book report. Roger Lewin is a British award-winning science author and writer of 20 books. He was employed at New Scientist in London for about nine years. He went to Washington, D.C. to write books and other pieces for science for ten years as news editor. The book by him that I chose, in 201 pages, this book explained answers to questions like where and when modern humans first appeared, what features distinguish modern humans
The origin of modern humans is one of the most widely debated concerns in the area of paleoanthropology. Ever since the discovery of the Neanderthal in the mid 1800’s, scientists such as Charles Darwin and many others have been overly curious about the similarity of man to certain great apes and how over long periods of time have evolved from different archaic forms of humans up to today’s homo sapiens. There are two major theories that encompass how modern humans may have evolved from the various
The Recent African Origins (Out of Africa) Hypothesis states that, modern humans evolved in Africa and then spread around the world. In other words, all of us can trace our origins back to Africa. On the other hand, we have the Multiregional hypothesis, stating that modern human evolved in many locations around the world from the species Homo erectus. However, this hypothesis and its followers have their back against the wall, due to the three very different strains of evidence supporting the Out
how did human beings evolve and where did they come from. Environmental conditions or pressures have been played importantly, that contributed to the selection of the genus Homo in Africa, Europe, Asia, Australia, and there is an anatomical evidence over the past one million years, culminating in our modern genome; leads to developing human cognition and explains why modern humans are the only ones who exists today. The history
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”
middle of paper ... ... several metrics did not provide the authors of this study with sufficient evidence to accept the idea of a population bottleneck roughly 70,000 years ago. However, they felt they had ample data supporting a bottleneck in human evolutionary history approximately 2 million years ago (Hawks et al., 2000). Though it cannot be decided in absolute terms either way, there is a plethora of information to support the concept that a bottleneck occurred in the late Pleistocene era
The origin of modern humans is a matter of debate. There are two different theories regarding the origin of modern humans or Homo sapiens. The first and primary theory states modern humans emerged in one place and from a single origin. This theory is known as the Recent African Origin Model. It suggests that modern humans are the product of speciation during the late Pleistocene in Africa. Homo sapiens eventually migrated out of Africa to Eurasia, and replaced all other human populations, without
Introduction: Modern humans, known scientifically as Homo sapiens sapiens, have evolved over time from other forms of life. Scientists are able to study some of this evolution through DNA and fossil research, but the exact process by which humans evolved and migrated across the world is still unknown. Genetic and archeological evidence can help scientists learn more about human history and create accurate timelines from human evolution and migration. Mitochondrial DNA plays an instrumental role
As it stands in the scientific community, there is currently a debate between two factions of anthropologists, and two theories, regarding the evolution of modern humans or Homo sapiens: The Regional Continuity Theory and the Replacement (or “Out-of-Africa”) Theory. In this paper, I will attempt to define both theories, evaluate the evidence and merits of both, and then draw a personal conclusion as to which theory I find the most plausible and likely to be correct out of the two. The Regional Continuity
Various authors have varyingly explored the origins of the blues, as a genre, possibly because of its influence in modern-day music world. In fact, the blues significantly influence today’s music scene and it is common to find other music genres borrowing from the blues in terms of style, tunes, as well as other features. Nevertheless, the blues have emerged as a widespread genre since its inception in the United States in the early 19th century. It is believed to belong to the popular (commonly
Gender and racial stratification have always prevailed in the United States society. As time matriculates, men continuously tend to possess more financial income than women in almost every occupational realm, and racial origin plays a vital role as well. This paper utilizes the most current United States Census Bureau’s database to examine and analyze the current and growing trends in gender and racial stratification and its impact on society’s sociological aspect. Through the detailed numerical
The Debate Over the Origin of Modern Homo Sapiens There has been a great deal of heated debate for the last few decades about where modern Homo sapiens originated. From the battle grounds, two main theories emerged. One theory, labeled “Out-of-Africa” or “population replacement” explains that all modern Homo sapiens evolved from a common Homo erectus ancestor in Africa 100,000 years ago. The species began to spread and replace all other archaic human-like populations around 35,000 to 89,000
according to the 2013 Professional Salon Industry Haircare Study. Because the hair industry is so lucrative, it is safe to say that hair is important to many. When researching a topic on genetics or human adaptation, there are limitations in understanding the connection between the texture of human hair and ethnicity. Such limitations include the variation of hair textures amongst a specific ethnicity. Because there is no uniform hair texture for each ethnicity, my research will require more digging
Hominids are a family that includes 7 different types of species. Its original meaning referred only to humans (Homo) and their closest non-extant relatives. That restrictive meaning has now been largely assumed by the term "hominin", which comprises all members of the human clade after the split from the chimpanzees (Pan). The time of the split between humans and living apes used to be thought to have occurred 15 to 20 million years ago, or even up to 30 or 40 million years ago. Some apes occurring
Aboriginal People: Dating the Colonization of Australia Abstract The colonization of each continent by modern human populations remains an important question in our history as a species. Studies of variations in mitochondrial genomes, Y-chromosomes, satellite DNA, and other genetic markers can be used to estimate the time of divergence of one population from another. Recent advancements in technology have advanced our capabilities in genetic analysis. In particular, PCR can be used to
In recent years, human rights scholarship has received much attention by various scholars, including by historians. More than other specialists, they have been particularly concerned with trying to comprehend the origins of modern human rights discourses. Some like Laurent Dubois in his Avengers of the New World: The Story of the Haitian Revolution have even suggested that: “the Haitian Revolution forever transformed the world. It was a central part of the destruction of slavery in the Americas,
language has experienced several shifts and transformations ever since its earliest history in the medieval England to the current. English has been historically said to have evolved through three major stages that include Old English, Middle English and Modern English. Each of the three stages may be also sub-divided into early and late stages in order to give a comprehensive picture of the language’s history. English language, According to Algeo (2010), originated from the various dialects used by the
pairs), representing a small fraction of the total DNA in cells. — Mitochondrial DNA contains 37 genes,” (Genetics Home Reference, NIH, 2014) The part of the DNA that we amplified was the D-loop region. This part of the mitochondrial genome is the origin of replication for the mitochondria. This part of the mitochondria is also “prone to somatic mutation, which are a type of non-inherited mutation.” (Genetics Home Reference, NIH, 2014) One’s mitochondrial DNA is only inherited from the maternal
Abstract Architecture is one of the most prestigious fields of knowledge and the most important expression of human interaction with the society and the environment in which it lives. The research deals with the subjective and objective terms and the relationship between them. The two links are related to the humanities in order to provide the cognitive background of the term and its reflection on functional and aesthetic architectural thought. This literature review focused on the clarification
Origins of Early Hominins Humans know or understand the theory of evolution and how they evolved from apes, but there is always talk of a missing link between apes and modern humans. Apes did not just suddenly evolve into modern day humans. Apes evolved into another species that fall into the relation of modern humans. This is what the missing link is referring to; we call the species hominins. Hominins comprised of many species actually, including but not limited to, Australopithecus afarensis and
