The Piltdown Man

‘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 slope. As they looked closer, more and more bones were found, including a jaw, arm bone, a thighbone, ribs, and vertebrae. Donald and Tom had cautiously examined the limited skeleton and calculated that a remarkable 40% of a hominid skeleton was salvaged,

In the Article “Redrawing Humanity’s Family Tree” by John Noble Wilford, describes how two different skulls challenge the theories of human origins and migrations. The Central African skull, that dates back to nearly 7 million years ago, was assigned to a whole new genus and species because of its apelike and evolved hominid species. The 1.75-million-year-old Georgian skull shows evidence that the first hominids may have been intercontinental travelers who set motion the migrations that occupied the whole planet. Finally a third skull was found that is the same age and shares a resemblance but, the size of the skull suggests that the brain was smaller than expected for H. erectus.

I decided to use the term "missing link" simply because around that time, scientists believed Piltdown man was, in fact, the "missing link" to our lineage from which we evolved. I did not use it because I believe it is an accurate depiction of the primate lineage. The faults which persuaded the perpetrator, or perpetrators, would depend on who was the one behind the Piltdown hoax. For instance, years later after Piltdown man was exposed as a hoax, a trunk with Martin A. C. Hilton's initials were found in the attic of the Natural History Museum after his passing. In in they discovered bones with carvings and stains similar to those of Piltdown man. Martin A. C. Hilton was known to not be very fond of Charles Dawson, his drive. Charles Dawson,

Afropithecus is a fairly large extinct ape- 50kg, characterized by a lack of a prehensile tail, long snout with procumbent incisors, generalized limb proportions and thick molar enamel. The braincase of Afropithecus is fairly small in size compared to other Miocene apes and Old World Monkeys from the same area. The primitive characteristics of Afropithecus suggest a relation to early catarrhines- such as Aegyptopithecus. And the post-cranial fossil record suggest that it was both arboreal and quadrupedal, similar to the proconsul that Afropithecus is categorized

In the first section of the book, before the trial, the foundation for the controversy was arranged. Charles Dawson discovered bones and other fragments of a skull that were known as the Piltdown skull. The Piltdown skull was first thought to have been from a normal ape, but later evidence collected from Arthur Smith Woodward said otherwise. The skull was said to have been from an

Throughout the term, reading the book, “Through a Window” by Jane Goodall has been quite intriguing for me, in that it has inspired me with new ideas and perceptions about how our own species has evolved over time. I have really enjoyed seeing the many similarities that hominids share with other primate species, especially chimpanzees. Goodall’s research only further proves that we are not only extremely biologically similar to chimpanzees in our DNA, but have many behavioral similarities as well. The film, “Monkey in the Mirror” also shows support for our likeness in intellectuality. These documented findings on chimpanzee and human resemblances provides the strong evidence needed to conclude the fact that humans do indeed share a common ancestor with great apes.

The “wrist morphology” is more similar to that of African ape/humans than that of Neanderthals or Homo Sapiens (iv.). The reason that this is contradictory to the theory that Lb1 is simply a mutated member of Homo Erectus is that the wrist structure actually forms during the early stages of prenatal development greatly decreasing the possibility that the wrist structure could have been a modified version of modern Homo’s. This evidence would indicate that Lb1 belongs to a species of Homo that branched off before the evolution of the modern wrist structure that was prevalent in more recent

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

He believes this shows a link between all species that ever lived such as microbes, sharks, frogs, bears, and their relation to man. Meaning that in the world of animal behavior we may have all came from a specific species and evolved throughout history. This may also shed light onto the animal behavior world by relaying some of the information that we know as being apart of out interconnectedness from one species. In reality his finding was a type of basis for humanity, it links our evolutionary world and all species together. The idea that we are all divergent parts of one evolution, really shows that the behavior an animal may have may also be explained by

NOVA scienceNOW : 41 - First Primates is a video that mainly talks about Primates who are ancient ancestors of human beings. Primates came out on the Earth 55million years ago when dinosaurs extinct due to collision between an immense comet and the Earth. Plesiadapiform, which is a possibly the first ancestor of primates and human beings, firstly evolved with a mouse-size organism during 10 million years. It existed during the 10 million year with diverse evidences that can show its validity of first ancester of primates. Nails of plesiadapiforms is a critical evidence that they are early ancestors of primates. Secondary proof is a tube-like structure which is found in the middle ear. It happens to be a tube for a huge vessel that goes to the

I glanced to see what the big fuss was about. It just had to be a bone. I can’t even get a decent day off of work. It’s rare to get a good day off, due to there being fewer than 60 certified forensic anthropologists in the entire country. It seemed a couple days old, 6 days at the most.I grabbed Manchitas and observed the scene first

Forensic anthropologists examined Kennewick Man’s skull and compared it to other skulls of Polynesians and native Americans. His skull is large and narrow with a projecting face. This does and resemble skulls of Native Americans. Scientists also created a clay facial reconstruction of the Kennewick Man using the information from his skull. The reconstruction shows similar features and facial structure to Polynesians, not Native Americans. The skull shows no resemblance to Native American skulls in structure. The morphology of the Kennewick Man’s skull further allude him as a Polynesian. (Achenbach,

This article focuses on the hyoid bone of a Neanderthal that was found in the Kebara cave located in Israel. A hyoid bone is a u-shaped bone which is located in the neck and helps supports the tongue. The hyoid certainly plays a dynamic role in speech and is a sign of the vocal tract. This hyoid bone found in 1989 heated up a scientific debate on the evolution of speech and complex language. According to the article “The mechanical performance of whole bones is partly controlled by internal trabecular geometries, regulated by bone-remodelling in response to the forces applied. Here we show that the Neanderthal and modern human hyoids also present very similar internal architectures and micro-biomechanical behaviors”. The anatomy of the Neanderthal

Their first discovery: a portion of a skull, would be one of the most telling artifacts of the expedition. The skull was, like the other bones
