LB-1 is name of the Homo floresiensis adult fossil, who was shorter than average human today. LB-1 fossil was discovered in Liang Bua, a cave on island of Flores in Indonesia. Generally Homo floresiensis are referred to as dwarf human with an average height being about 3.5 ft. Also, this is how they’ve earned the nickname “hobbit.”
Homo floresiensis brain, prior to this paper, was estimated to be about 380 to 430 cc (cubic centimeters), which is very small. Reasons for such small brain size have been greatly debated. There are two main hypothesis. First of them is that an ancestor Homo erectus, whose brain is approximately 1000 cc, wandered onto the island Flores, and his descendants underwent brain shrinkage. Second hypothesis is that Homo floresiensis is directly descended from smaller-brained species like Homo habilis ( about 600 cc) or

floresiensis. Some hypothesize that H. floresiensis originated from H. erectus, while others hypothesize origin from H. habilis or Australopithecus, but there is no conclusive evidence to prove these hypotheses. Given that most of findings prior to this study indicate possibility that it was particularly Indonesian H. erectus and not general H. erectus that is hypothetical ancestor to H. floresiensis. They’ve taken ECV and femoral head diameter (FHD) for 20 chrono-regional groups of Holocene H. sapiens worldwide. Then, they’ve predicted ECV values after simulated body size reduction in two speculated ancestors to H. floresiensis, which are H. habilis and Indonesian H. erectus. Males and females were analysed separately. The male data showed that if a body of H. habilis reduced to the size of LB1, then ECV would be 447-449cc, which is 11-12% larger than the measured ECV of 426 cc. If a body of the earliest Indonesian H. erectus reduced to that of LB1, then ECV would be 522-58
Chinese and Malaysian Homo Sapiens have very close features to the Neanderthal. The skull analysis of Neanderthals and Homo sapiens are usually considered more accurate if the entire skull is examined, rather than certain ...
A study performed by Martin Hausler and Peter Schmid of the University of Zurich, Switzerland, appeared in the October 1995 issue of Journal of Human Evolution, igniting controversy over the 1974 Australopithecus discoveries in Hadar, Ethiopia. The most famous of the Hadar specimens is the 3-million-year-old skeleton, “Lucy,” who was recovered by paleoanthropologist, Donald Johanson. In his article, Shreeve presents the methods and findings of Hausler and Schmid’s study as well as some counter arguments from other scientists in the field.
Every few years, Hollywood releases a new Planet of the Ape movie, which is always a blockbuster hit. Moviegoers flock to see these movies of how apes rise together and how they are actually more intelligent than meets the eye. Most people do not know the premise behind these movies of how smart and closely related apes are to humans. This is because people probably have never taken a physical anthropology class and have not done research on apes –our closet kins. Known for his immense studies in the fields of apes and monkeys, his long term research in the behavior of chimpanzees and mountain gorillas, and his experience in the forests with the apes, the co-director of the Jane Goodall Research Center and writer of our textbook, primatologist
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...
Bigfoot is, without a doubt, the most recognized mystery in all of North America. The apelike being has reportedly been sighted thousands of times since the beginning of the 19th century. According to eyewitness testimonies, Bigfoot, also known as Sasqautch, is a gigantic beast that towers in at eight feet tall and weighs as much as six hundred pounds. Reports also say that the monster’s form is well built and usually covered in a thick, brownish fur. Many have asked if such a creature could possibly be roaming through the wilderness of North America and around the world, and the answer is yes. The amount of evidence supporting such a creature’s existence is astonishing. From footprint casting and fur samples to video evidence and numerous human sightings, Bigfoot’s existence cannot be doubted.
“The Victoria Colonist, July 3, 1884, reported the capture of a "gorilla type" creature, six feet six inches tall, weighing from 400- 1000 pounds and covered with glossy hair an inch long.” Although, other 19th
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.
"On the Origin of Species by Means of Natural Selection, or the Preservation of Favoured Races in the Struggle for Life," usually shortened to "the Origin of Species," is the full title of Charles Darwin's book, first published in 1859, in which Darwin formalized what we know today as the Theory of Evolution. Although Darwin is the most famous exponent of this theory, he was by no means the first person to suspect the workings of evolution. In fact, Charles owed a considerable debt to his grandfather Erasmus, a leading scientist and intellectual, who published a paper in 1794, calledZoonomia, or, The Laws of Organic Life. This set down many of the ideas that his grandson elaborated on 70 years later.
...ro-Magnon. The chin however recedes slightly behind the teeth, which is typically a Neanderthal trait. The age of the fossil is interesting also, because 25,000 years ago Neanderthals weren’t around anymore, so the boy is essentially a modern human with Neanderthal traits (Kunzig, 160).
Humanity became fascinated with the idea of evolution with the work of Charles Darwin and the Scientific Revolution. People began hunting for fossils that would prove that man had an ape derived ancestry (Weiner, 1955). After various years of searching, a piece of physical evidence was found in England that was said to confirm the theory of evolution (Weiner, 1955).This confirmation came from Charles Dawson’s discoveries from 1908, that were announced publicly in 1912 (Thackeray, 2011). Dawson was believed to have found the fossil remains of the “missing link” between ape and human evolution, the reconstructed skull of Piltdown man (Augustine, 2006). The material was found in stratigraphical evidence and animal remains that were, at the time, adequate enough to confirm the antiquity of the remains (Weiner, 1955). In 1915, another specimen, Piltdown man II, was found further proving this theory (Augustine, 2006). However, this was merely a hoax proven by fluorine relative dating in 1953; the artifacts and bone fragments discovered turned out to be altered to fit the proposed scenario (Augustine, 2006). The skull found was actually composed of a human braincase that was younger than the complimentary orangutan lower jaw (Falk, 2011). Both sections of the skull had been stained to appear to be from the same person of the same age (Falk, 2011).The perpetrator of this act was never caught and there are many theories proposed for the motive of this hoax (Augustine, 2006). Many people have been taken into consideration for this crime, such as Chardin, Woodward, Hinton, and Dawson (Augustine, 2006). Nevertheless, the evidence that proves that Dawson is guilty of this crime against anthropology is quite substantial compared to the evidence...

The members of the Homo genus possess a combination of unique features that distinguish them from other related species. At the time that each respective species was alive, they were able to walk upright on two legs, use their large brains for the benefit of their species, and could thrive in many geographically and climatically diverse areas of the world. One of the most mysterious quandaries in science is how the lineage of the Homo genus became so different from their primate relatives. Bipedalism, brain size, and location diversity all have a common link that may explain this difference – dietary evolution allowed humans to adapt to their surroundings, and in turn, become a more advanced species. The Homo diet evolved in relation to food availability and nutritional necessity. With the ability to maintain a proper diet, the species of the Homo genus were able to flourish and advance toward the development of modern Homo sapiens.
The evidence for human evolution begins with the australopithecines. All the australopithecines were bipedal and therefore possible hominines. In details of their teeth, jaws, and brain size, however, they modify enough among themselves to be divided into five species: Australopithecus anamensis, A. afarensis, A. africanus, A. robustus, and A. boisei. Genus Homo are also divided in five different spices: Homo erectus, H. habilis, H. sapiens, and H. sapiens sapiens.
The evolution of man as a species can be traced with limited fossil evidence, but the development of the mind takes a different course of investigation. "Unfortunately, no hominoid fossils- nor such of a fossil chimpanzee- are as yet known for the period between 6 and 13 mya. Thus there is no documentation of the branching event between the hominoid fossil and the chimpanzee lineages" ( What 239).
