Summary Of Darwin And The Recent African Origin Of Modern Humans

711 Words3 Pages

In the article “Darwin and the recent African origin of modern humans”, Richard Klein dives into our understanding of the origin of modern humans and how it too, has evolved through time. Klein offers examples and rationale behind the thought process of Charles Darwin, Thomas Huxely and other specialist of modern human’s history. Through this process we are given better understanding of who modern humans evolved from and where we are from.
Charles Darwin’s theory of evolution was a revolutionary theory during his time and still is in our world today. It challenged people to look closer at the world as whole. In Darwin’s second book “The Descent of Man” he displayed a multitude of comparative data from anatomical, embryological, and behavioral …show more content…

Fossil records have supported their assumptions. During their active years, many of Darwin’s and Huxley’s colleagues believed the human race represented sporadically evolved populations of Homo sapiens. This theory has since been discredited. In 1891 Eugene Dubois found the first human fossil, before these only Neanderthal fossils were being compared to those of modern humans. This finding is viewed as the first specimen of the Homo erectus species. Subsequent findings that diverged from the Neanderthal morphology followed years later. Together these findings depicted to scientists the basic development of human …show more content…

Natural selection and random genetic drift occurred after this initial expansion out of Africa, which evolved to at least three Homo lineages: Homo sapiens, Homo neaderthalensis, and Homo erectus. Archeological and composite fossil records suggest the African lineage spread and replaced others roughly 50,000 years ago. Genes from living human’s places the source population for the spread was most likely located in eastern or southern Africa. Many specialists consider that the Darwinian fitness advantage allowed modern humans to survive and reproduce at much higher rates than the archaic humans in Eurasia. The Darwinian fitness is said to be a result of increased brain capacity or behavioral changes towards social, economic, demographic and most likely population

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.

Summary Of The Book That Changed America By Randall Fuller

1057 Words | 5 Pages

In his acclaimed novel, “The Book that Changed America: How Darwin’s Theory of Evolution Ignited a Nation,” Randall Fuller explores the groundbreaking work of esteemed natural biologist Charles Darwin and his 1859 work, “On the Origin of Species by Means of Natural Selection.” He documents the work’s travels throughout America and its circulation among New England’s intellectual elite, focusing on the explosive reactions to its previously unimaginable claims; theologians, scientists, Transcendentalist philosophers, abolitionists, and pro-slavery apologists alike all had something to say about this new theory. Fuller’s brilliant interpretation of this cultural upheaval, using personal writings from the desks of intellectual giants, cements Darwin’s

Nonhuman Primate Evolution

195 Words | 1 Pages

climate change influenced nonhuman primate evolution because with the changes, nonhuman primates were forced to evolve in order to survive. As the climate change progressed and several species started to die out, nonhuman primates evolved through time and thus they were able to survive and climate change that occurred and were able to evolve into creatures that we see during present times. The theories of early primate evolution appeared about 60 million years ago after most of the early living species had already become extinct. New discoveries have supported one theory over another as more research is done.

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.

Darwinism And Imperialism

1557 Words | 7 Pages

Charles Darwin’s theory of evolution i.e. “survival of the fittest” and the “process of natural selection“, was written in 1859 and was a theory based on the behaviour of animals. This theory was adapted by Herbert Spencer and resulted in the ideology that is known today as Social Darwinism. The latter is based on Darwin’s theory but instead of being based on animal behaviour it is applied to humans. It implied that certain races were superior to others because of their technological advancements. This lead people to believe that certain races, such as white/European people, were the “fittest” of all the races.

In the study of physics as a whole there are numerous names that are influential to the advancement of physics however there are two names that will always stick out as the founder and fathers of physics; Galileo Galilei and Isaac Newton. Galileo was born February 15, 1564 in Pisa Italy. He attended the University of Pisa from 1581-1585. He helped to mathematically describe ballistics, and the force of friction as it relates to motion. After experimenting with moving objects, he established his "Principle of Inertia", which was similar to Newton's First Law.

What Are The Arguments Against Darwin's Theory Of Evolution

1126 Words | 5 Pages

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).

Out Of Africa Theory Essay

1042 Words | 5 Pages

The primary view, the Out of Africa theory, suggests that modern humans originated from a single source in Africa, which geographically, according to Professor Johanson (2001) of Arizona State University and discoverer of Lucy, includes the Middle East. According to this view, Homo erectus, migrated out of Africa, spread through Europe and Asia and evolved independently, sometimes even into different species such as Homo neanderthalensis. Homo sapiens evolved from African descendents of Homo ergaster about 195 000 years ago (Pickrell, 2006), and began migrating out of Africa and replacing all other hominin populations. Diverse groups of hominin species inhabited the world.
