Human skull

first organism with a nucleus lived one and a half million years ago. An animal with a braincase and a beginning of a backbone appeared 500 million years ago. Amniotes were split into two main lineages. One is identified by a hole that evolved in the skull behind the eye socket called synapsid opening. The second lineage is recognized by a pair of holes that evolved in the palate; this was the beginning of Sauropsids, or reptiles. The first dinosaur was recognized by a hole in its hip socket.…

fourteen inches in height and should weigh anywhere from forty to sixty pounds (Colie 32). Basset Hounds have thick, hanging lips and soft, sad eyes along with ears that hang low to the ground. On its head, there is loosely wrinkled skin and a domed skull that is most clearly seen at the back of the head. The Hounds have a straight spine and a slightly curved tail. Also, large, round feet and short legs with wrinkled skin (Colie and Earle-Bridges 68-69). Historically, the Basset Hound is a…

There are many definitions of the word story, but one definition in particular fits the topic of human origins perfectly; a narration of the events in the life of a person or the existence of a thing, or such events as a subject for narration. The story of human origin and the creation of human nature is a difficult story to tell, created by miniscule pieces of evidence and guesswork through paleoanthropology, and advances in the ability to look at and study DNA. Exactly where we came from and…

When I went to the Smithsonian Human Origins Exhibit, it made me realize how much more I am informed about human evolution compared to most of the people at the exhibit. One thing was I saw on one the displays that Neanderthals were classified as part of the Homo sapiens lineage, which is not true. During our lecture you already told us that Neanderthals are not part of the lineage. Neanderthals are consider more like sisters than one of us. Also one of the speakers was saying how Homo…

or feeling dysphoric? Are you in need of five hundred dollars? Well, do we have an offer for you! After many years of experimentation, Illinois born and raised Dr. Harrigan and a team of highly trained professionals have devised a way to swap two human minds into the other's body. This would make transitioning much easier and eliminate the need for hormone therapy or surgeries intended for this propose, provided one may look quite different from his or her original genetic make up. Up to this…

Human evolution is the long process of change in which humankind originated from apes. Before Charles Darwin, Carolus Linnaeus, chose the word,”homo,” which is Latin for human, in his classification system. During this time, along with Linnaeus, other scientists considered apes to be close relatives to humans due to their anatomical similarities. In the 1960s and 70s, African researchers found fossils of australopithecines, an extinct creature related to humankind in Africa. Later more fossils…

Human phylogenetic trees differ according to available data. In some, for example, Homo erectus is shown to be one of Homo sapien’s ancestors. Neanderthals are shown to be co-descendants with archaic Homo sapiens and as a dead end in the human phylogenetic tree. This would mean that they went extinct without contributing genes to modern humans. In other trees, Neanderthals are shown to have interbred with modern Homo sapiens. There are sources that claim that Homo erectus is the first hominid to…

The Australopithecus afarnesis’ set foot to this earth three to four million years ago. The Australopithecus afarensis originated in Eastern Africa, and they were part human, but mostly ape. The archeologists Donald Johanson and Tom Gray discovered the first of the early man’s kind accidentally. When they were when back to their van after a dig in the surrounding area, they found bones on the ground. After further investigation, they discovered that these bones were of Lucy, the first early man…

Intro Modern human evolution has changed dramatically over thousands even millions of years. Recently, researchers have identified a newly proven ancestor to modern humans whom are Neanderthals. Looking at archaic DNA and comparing it with non-African modern human DNA, it is clear to see that we share a great deal of common genetic information with Neanderthals than researchers first thought. With extensive research, researchers and scientists have been able to pinpoint genetic differences…

Current Events Assignment #7 Celimar Burgos Title: Foot fossils of human relative illustrate evolutionary 'messiness' of bipedal walking. This article explains the new study on the extinct human relative, Homo naledi that was discovered in a cave in South Africa in 2013 and recently describes last month. The discovery has to do with his feet, that although considered to be the most human-like feature of his body, besides being useful for standing and walking on them they were also good for…
