Human Evolution Essay

understanding human evolution and the history of psychology for the modern psychologist. For the human evolution, the essay will be addressing on how we and other species descended from our ancestors and how the different environment has helped to us to become more adaptable. Regarding the history of psychology, the essay will be discussing on how psychology branched off from the philosophy approach to become its own science. The essay will then go on discussing how the understanding of both human evolution

The Evolution of Human Speech As human we can communicate via our speaking ability to express our feelings, as a way to deliver the message we want another. These articles that I read discuss the anatomical prerequisite for humans to gain the ability to speak such as the absent and present of the air sac in hominids. Morphological changes of the face structure such as the reduced growth of the palate and the descent of the larynx. The controversial hypotheses of the hypoglossal canal size are indicative

Human evolution according to research started over 6 million years ago. The outcome of the evolution process is the current human beings. Scientific studies have revealed over the years a remarkable affinity between the chimpanzees/Apes and human beings. Even though this reality is not a definitive prove that human beings evolved from apes, it does show that the human beings are in one way or another related to other primates. Scientists suppose that the humans and the primates shared a common

found the fossils of a human that looks so different than anything they have found before and that existed not that long ago. I believe based on the evidence and the different articles that it is a new species. If that truly is the case, then that is amazing to even think about. There is dissimilarity within species; there are also discrete species. The term hominid is a member of the zoological family Hominidae. Hominidae incorporates all species instigating after the human/African ape familial divided

While time travel still remains elusive to us, scientists have been able to discover things about our past as a species that were practically inconceivable over 150 years ago when Charles Darwin released his book entitled The Origin of Species. They have especially uncovered many pieces to our still incomplete puzzle over the past 20 years so that we now have a nearly complete idea of how our species Homo sapiens came to be. This story of our history includes dozens of species’ and hundreds of fossils

Biological anthropologists have researched that humans evolved mostly in Africa, where they originated. I also agree with this since there are many fossil records of early humans, and more modern humans in Asia, Europe, Australia, and the Americas. As time passed, they evolved, climate changed, and natural selection occurred. With this climate change, populations fluctuate and mutations occur between generations. As you will see, humans have gone through much natural selection to be who we are now

‘Lucy’ was exposed by Donald Johanson, an anthropologist, with his team, went to survey Hadar in Ethiopia during the late 1970s for signs in understanding Human origins. On November 24, 1974 by the Awash River, Donald’s’ plan for the day was to update his notes but decided otherwise when one of his students, Tom Gray, joined him to find fossil bones. Both of them were on the hot waterless plains examining the sandy terrain when a fossil was spotted; it turned out to be an arm bone fragments on a

Humans, formally known as Homo sapiens, are some of the most fascinating creatures to inhabit this planet. We as human animals possess many traits unique to our species, but one of the most remarkable traits is our upright posture and inherent inclination to walk on two legs. We share this rare trait with few organisms, who even so only express limited bipedal behaviors. Human ancestors first initiated the transition to bipedalism approximately 6 million years ago through the upright steps of the

This property allows us to find the maternal genealogy of our species, and that all of the mtDNA types in the entire population of humans today must trace back to a single common female ancestor, the ‘mitochondrial Eve’. All analysis of mtDNA variation in modern human populations basically agree that she lived in Africa roughly 150,000–200,000 years ago, and modern humans then began dispersal across and out of Africa between 50,000 and 100,000 years ago. In recent decades, however, some evangelicals

The Theories of Evolution The human population has always wondered where they came from, or how they came to be. Why do they have certain characteristics that distinguish them from other species, or how did they acquire these characteristics? Why do they have similar traits to other species? There are many questions about the existence of the human population that they would love to have the answer to. Unfortunately, there is not an answer that is a proven fact. Luckily, there are theories that
