Humans Were Affected By Island Dwarfism ( Morwood )

A. C. H., was discovered in the loft space above the office of the Keeper of Zoology—the office Hinton had occupied from 1936 to 1945. This was the first concrete evidence implicating Hinton in the Piltdown hoax (Gardiner, 2003). Contained in the trunk were x teeth similarly stained to the materials discovered at Piltdown I, while several other materials, such as elephant and hippopotami teeth and bone fragments, had been whitened similar in fashion to the ‘cricket bat’ found at the Piltdown II site; the cricket bat having been made form an elephant femur. Hinton had experimented with bone and tooth staining (De Groote et al., 2016) predominantly staining them with iron to match the gravels of a Pleistocene era (Gardiner, 2003)… Also among Hinton’s effects, were eight human teeth that had been stained with iron, chromium, and manganese (Gardiner & Currant, 1996), similar to those of the Piltdown site. When the fluorine dating method was implemented this further incriminated Hinton as the findings from the Piltdown I site evidenced “a recent ape jaw and canine had been artificially modified, stained and planted at Piltdown I, along with parts of a similarly stained recent human skull” (De Groote, 2016, p. 4). The method Hinton practiced (evidenced by the findings in his trunk) was unique to him—a signature—therefore, implicating him as the Piltdown

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.

Homo floresiensis (“Man of Flores”) is the name for a possible new species in the genus Homo, remarkable for its small body, small brain, and survival until relatively recent times (www.en.wikipedia.org). Anthropologists Peter Brown of University of New England in South Wales, Australia, Michael Morwood and their colleagues have argued that a variety of features, both primitive and derived, identified LB1 (the first skeleton found in cave of Liang Bua) is that of a new species of hominin, Homo floresiensis. The first specimens were discovered by Thomas Sutikna and colleagues from the Indonesian Research Centre for Archaeology in Liang Bua cave of Flores, Indonesia in September of 2003

The importance of the research being done based on this find is explained within this same article in a quote from Chris Stringer of the Natural History Museum, London saying, “A find like this does make us question the trees people have built up of human evolution”(Noble, 2002). Not only is finding this skull phenomenal, but the implications it holds are tremendous. The idea that one fossil such as this can change the way we have thought about human evolution is a huge deal that deserves much research and even much speculation and dispute.

Darwin once hypothesized that humans evolved from an ape like ancestor and that those ancestors most likely originated in Africa since the majority of the great apes lived there. Unfortunately, Darwin’s hypothesis was ignored for reasons such as people (e.g. Europeans) not liking of having African ancestors—not to mention the lack of evidence did not help in supporting such hypothesis. Thus, finding the missing link between apes and humans was of great important—it still is. Thankfully, through extensive research many scientists have been able to determine a clade called Hominin [7]. This clade contains humans as well as their most closely related relatives.

At the beginning of his book “Your Inner Fish” Neil Shubin asks this question: “How can we visualize events that happened millions, and, in many cases, billions of years ago?” There were no eyewitnesses, Shubin says, no humans were around. The percentage of organisms that have been fossilized is very small and only certain species will ever be fossilized because of where they were located. However, this information did not intimidate Shubin on his hunt for his precious fish bones. Neil ties in the theory of evolution to explain how although life on Earth is widely diverse, all species have common ancestors. With the fish bones, he aimed to show how evolution caused one of the great transitions life has ever made- the transition from the ocean to land. Shubin, after six years, finds what he was looking for with the discovery of the fossil named Tiktaalik. This particular fossil is an intermediate between fish and primitive land-living animal.1

The discovery of the remains of an apparently miniature hominin species (catalogued as Lb1) on the island of Flores has sparked debate throughout the archaeological community. This species of hominin is unique in a number of aspects and appears contradictory to trends in archaeological evidence and theories about the development of modern humans in that area of the world.

“How old is the oldest human fossil?,” If you had said about 700,000 years, you would probably have been right until just recently that is, “The September 1998 issue of Discover magazine”, reports that Ernesto Abbate, a geology professor from Florence, Italy, has just discovered the fossilized skull and teeth of a humanlike creature who might have lived, as far back as, one million years ago. Calling this creature Buia Man after the city in northeastern Africa where the remains were found. Prof. Abbate thinks he has discovered the earliest fossil that displays physical features associated with Homo sapiens, the species to which modern humans belong. Moreover, Buia Man says, Prof. Abbate also shows physical

Another major phenotype to be discussed is the drastically divergent brain size when compared to other Homo species. The LB1 remains contain a cranium with a volume of 380cm3 (Brown, et al.). When this brain size is compared to a modern Homo sapiens volume of approximately 1300cm3 (Cosgrove, et al), the difference is almost laughable. Instead, the LB1 cranial capacity is more analogous with that of genus Australopithecus, at 450cm3 (Roth and Dicke), which would seem to indicate that the brain size of the specimen is primitively determined.

When I began searching for an article on my topic, I already know that this prehistoric species was found on Flores. I also knew that Flores an island.

A longstanding view of human evolution holds that the first hominids to leave Africa did so with the help of bigger brains, longer legs and fancier tools than those of their predecessors. That scenario suffered a major blow a couple of years ago, however, when paleontologists working in Dmanisi, Georgia unearthed the oldest human remains yet found outside of Africa---two 1.7-million-year-old skulls belonging to early members of our genus, Homo--and discovered primitive tools alongside them. Now a new finding may topple another pillar of the theory. According to a report in the current issue of the journal Science,researchers working at the same site have recovered a third skull--one that housed a surprisingly small brain.

The Homo erectus fossils were first discovered in October 1891 on the island of Java, Indonesia by Dutch anatomist named Eugene Dubois during his research in finding more fossils he named “the missing link.” Initially, Dubois found a petrified skullcap “with a cranial capacity of slightly over 900 cm” by the Solo River, nearby the town of Trinil; and then, in 1892, a human femur unearthed 15 yards away from where he discovered the skullcap and so, Dubois presumed and claimed that both skullcap and femur pertain to the same individual and named it Pithecanthropus erectus. Based on the study of Javanese geology, the fossils of all Javanese Homo erectus have derived from the eastern part of the island, and so, most of the fossils belong to Early

       In the article, "Natural History of Homo erectus" by Susan C. Antón discussed our view of H. erectus is different today than when Pithecanthropus erectus, then only the second fossil hominin taxon to be discovered, was described by Dubois (1894) (Antón, C. Susan, 162). H. erectus was the most primitive and smallest-brained of the fossil hominins (Antón, C. Susan, 162). Therefore, early observations expended significant effort showing that the Indonesian fossils from Trinil were actually hominins (Antón, C. Susan, 162). Thus, it took the dismissal of Piltdown and the broad acceptance of Australopithecus as a hominin ancestor, along with the substantial Asian

Hominids with a brain absolutely and relatively larger than that of the australopithecines appeared about 2.3 million years ago. These hominids are classified in our own genus: Homo. The earliest species to appear was the Homo Habilis. It was the first of our ancestors to show a significant increase in brain size and also the first to be found associated with stone tools. These characteristics resulted in this species’ placement into the human genus, Homo.
