In 2004 a group of scientists found the partial skeleton of a new human species we had never seen before. Researchers called the remains LB1, also nicknamed the hobbit due to its small size. It was first believed that this new species, Homo floresiensis, was a descendent of Homo erectus that had simply dwarfed over time due to limited access to resources. However, newer studies have highlighted some of the more primitive characteristics of LB1, which lead scientists to believe that the hobbits branched off from the human family tree much earlier than previously thought.…
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 (www.newscientist.com). It’s most important and obvious identifying features were its small body and small brain. These species have been established to have survived on Flores until at least 12,000 years ago. However, there are still some anthropologists, such as Professor Teuku Jacob, who would claim these findings as anything but extraordinary. Whether these specimens represent a new species or not is a controversial issue within the scientific community as a growing number of scientists are challenging this sensational discovery.…

Before Jane Goodall’s discovery scientists believed that non-human primates lived simple life. It turns out that they are highly intelligent, emotional creatures that live in complex societies. This new discovery lead people to feel compassion and concern for the animals. Leakey’s once said “new we must redefine tool, redefine man, or consider chimpanzees as humans”. We now see that we are not alone with being advanced that there are other non-human primates that also are advancing.…
In total, Homo floresiensis’ characteristics of a small brain and cranium, short stature, length and robustness of limbs, and structure and length of feet are analogous to that of an australopthicine, however, the elongated, less prognathous facial structure, teeth, and shape of the brain are considered to be characteristics derived from a species of Homo (Meijer et al., 2010:1002). This discrepancy in analogous structures to any known ancient species fuels the controversy throughout the field of anthropology; who were the Homo floresiensis, and from whom were they…

Evolutionary theory explains the existence of homologous structures adapted to different purposes as the result of descent with modification from a common ancestor. Similarities and differences among homologous structures help determine how recently species shared a common ancestor. For example the front limbs of reptiles and birds are more similar to each other than either is to the front limb of an mammal. This similarity indicates…
A group of scientists lead by Biren Patel have recently found a partial mandible of an ancient primate related to lemurs. Scientists have named the new species Ramadapis sahnii and claim that it existed 11 to 14 million years ago, and is a member of the early primate family Sivaladapidae. Analysis of the jawbone shows that the species consumed leaves and was approximately the same size as a house cat, or to a modern day lemur. This discovery is important to the scientific community as with this discovery more information surrounding the evolutionary history of primates can be gathered and analysed. This new species will also help expand the phylogenetic tree for primates, making it significant to any scientist researching primate evolution.…

Conclusion: While conducting this experiment I have come to the conclusion that my hypothesis was rejected. My hypothesis stated that 4 of the skulls would be bipedal. It turned out that five of them were bipedal. All of the the skulls in the ‘homo’ section were bipedal. The reason why many people think humans evolved from apes is because our structure is similar but as you learned that is not the case. As time passed humans have evolved in many ways. Based solely on the skulls from the ‘homo’ section, as you went ahead to the next one the heads became a little bit smaller. Also the zygomatic (cheek) bone shrunk. We humans are species that have evolved in many different ways over a long period of…
