Toumai, The Oldest Relative of the Human Race
Discoveries relating to the human lineage are extremely exciting and often baffling. This is the case with the recent discovery of what seems to be the oldest member of the human family. A skull found in northern Chad in 2001, has been deemed the earliest relative to the human ever found. Nicknamed Toumai, and discovered by Michel Brunet and his paleontology team, this new category of human has been given the scientific name, Sahelanthropus tchaensis. What makes this skull so definitive is the fact that it dates back approximately 6-7 million years in the earth’s history (Whitfield 2002). Since the discovery there have been anthropologists and paleontologists that have disputed the hominid status of Toumai (Evans 2002), but many, especially those involved in the finding of the skull still believe that they have the oldest relative to the human race we know today.
The kind of attention that comes from discovering a fossil that may challenge pre-existing notions of human lineage is massive. When the findings were first published in “Nature” and “Science”, scientific journals, the news spread like wildfire and every news source from ABC to the BBC had the story covered. A discovery of this magnitude is highly important considering it can alter thoughts about the beginnings of the human line and cause an uproar in the science community in terms of the way human evolution is looked at. BBC News was one of the sources that covered this story when the discovery was made. Their primary article stated, “Scientists say it is the most important discovery in the search for the origins of humankind since the first Australopithecus ‘ape-man’ remains were found in Africa i...

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.
On November 24, 1974, an American Anthropologist by the name of Donald Johanson and his research team, made a ground-breaking discovery that caused a mass dispute in human evolution. Dr. Johanson documented in his book, Lucy The Beginning Of Mankind, the discoveries he and his team have come across. Dr. Johanson and his team discovered a skeleton of a hominid, dated between 3.9 to 3 million years old (164). The hominid, which they referred to as Lucy, was discovered while surveying Hadar, in the Dafar region of Ethiopia (164-166). Lucy’s discovery, a 41% complete human ancestor caused a controversial alteration in the human origins. Lucy was the oldest human ancestor. During the following year, Johanson’s team discovered fossilized remains
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...
Copyright and fair use laws are laws that allow for creators of works to have rights to their creations. But, they also allow the free use of works, in the effort to get your point across. Fair use can be defined as the doctrine that brief excerpts of copyrighted material may, under certain circumstances, be quoted verbatim for purposes such as criticism, news reporting, teaching, and research, without the need for permission from or payment to the copyright holder. This doctrine shows how the general public is available to reproduce copyrighted material without acquiring consent. While, this is true, we are only allowed to reproduce part of the information, not the entirety of the work. These can include news reporting, teaching purposes,
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.
Were Neanderthals the same as modern humans, or were they an entirely different species? This is a major topic of debate among Anthropologists, and many people strongly argue each view, backing their opinion with evidence from physical remains and inferred ideas about behavior.

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.

The amount and substantiality of the portion used in relation to the copyrighted work as a whole
Just two decades ago, saying “copyright” to teachers most likely conjured images in their minds only of the fine-print notice in the front of a textbook. Today, with a world of Web 2.0 technology at their fingertips, copyright issues for teachers can be confusing and complex. Add to that an ever-increasing emphasis on technology literacy in our states’ education standards – forcing teachers to incorporate applications and resources that may be uncharted territory to them – and the waters get even murkier. Teachers bear the double-burden of carefully abiding by copyright laws in their day-to-day incorporation of technology in the classroom, while instilling copyright ethics in students as they meet state standards for technology and media literacy. A review of the copyright literature related to education provides some clarity on copyright and fair use applied to classroom practices, suggests barriers to copyright compliance among educators, and provides suggestions on how to teach copyright ethics to a tech-savvy generation.

Plagiarism and Copyright Infringement are two terms that mean different things yet are routinely mentioned as synonyms for each other. This is not the case. The underlying reasoning for people who choose to plagiarize and infringe on copyrights involve some of the same ethics and morals, but from a legal standpoint these terms mean different things. This paper will point out the similarities and differences between the two terms. It will first give some meaning and perspective behind each term then it will go into the details of what each term means. It will point out the types of plagiarism that routinely show in academia and what is covered under Copyright law protection. It will go on to compare and contrast the two concepts.
