A New Genus of Hominins Found in Kenya
Whenever finding new fossils, most people get excited in learning more about the mysterious history of life on earth. No one fossil finding may be more important than another, but when discovering a fossil that adds a new genus name to a species, it gets exciting. This is especially true when the fossil gives more insight to the evolution of humans.
In Kenya, a new genus of hominins was found. The new genus was assigned because this hominin had a combination of derived facial and primitive neurocranial features. This hominin is guessed to be about 3.5 million years old. The findings lead the scientists to an early diet-driven adaptive radiation, which gives insight on the craniodental features, or the structure of the skull and mouth. The name of the species is Kentanthropus platyops (the Flat-Faced Man of Kenya). This fossil was found in a rugged desert-like site on the western shore of a lake in northern Kenya. This is by the Topernawi river drainages in Turkana district in northern Kenya.
This fossil is known to be twice as old as Lucy, a famous Australopithecus afarensis, which is only about 1.8 million years old itself. The age of this fossil has been established because it was found in between layers of different aged soil. Eight meters below the Tulu Bor Tuff and 12 meters about the Lokochot Tuff is about 3.5 million years old, this is an area called Kataboi Member where the type of specimen is found. The paratype is from lower Lomekwi Member, seventenn meters above the Tulu Bor Tuff, estimating at 3.3 million years old. Kentanthropus platyops is estimated to be about 3.5 million years old itself.
The age can also be estimated aroun 3.5 million years because hominin findings from Lomekwi, two mandibles and isolated molars have previously been found, which indicate the time period. The skull was found amongst a temporal bone that was well-preserved, two partial maxillae, some isolated teeth, and an extremely complete, yet distorted, cranium.
The most astonishing thing about the skull is that it looks remarkably similar to that of a human skull. Note the platyops, platus coming from the Greek word that means flat, and opsis, meaning face. Thus making the name "Flat-Faced Man."
Of course there are many differences than a human skull, but it is extremely similar to that of one.
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 ...
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
However due to globalization, import and export viruses is more easily transmitted. Over the past century the global community especially Asian has been affected with new strains of the influenza virus. The changes in the virus can occur in two ways “antigenic drift” which are gradual changes in the virus over time. This change produces new strains that the antibody may not recognize. “Antigenic shift” On the other is a sudden change in the influenza virus which ‘’ results in a new influenza A subtype or a virus with a hemagglutinin or a hemagglutinin and neuraminidase combination that has emerged from an animal population,” as seen with H5N1 virus. This change leaves people defenseless against this new virus. (CDC, 2013) Currently there is no vaccine to combat all strains therefore “Planning and preparedness for implementing mitigation strategies during a pandemic requires participation by all levels o...
Society tries to exclude those they find unwanted or undesirable. With the Athenian Polis, it was about controlling citizenship. They were free to work, study, and trade within Athens, but were left out from the rich politician lifestyle. In modern immigrants, the focus is on Mexicans of the United States or North Africans in France, but as Dwyer noted it is far more diverse and complex than that. The number of illegal immigrants is unknown, with around 35 million in the United States to a third of Europe’s
...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).

Most studies in marital conflict pertain to three particular dimensions of communication. The first dimension is affect which refers to messages that express positive or negative feelings about another person, such as supportiveness, hostility, confirmation, coercion, sarcasm, or global positiveness or negativeness (e.g., Gottman, 1979 and Sillars and Wilmot, 1994). The second dimension to characterize conflict behaviors is whether they are constructive or destructive for the parties’ relationship. Research in the United States indicates that exiting from the relationship and neglecting the partner are destructive problem-solving responses and are more powerfully predictive of couple distress than giving voice to problems and being passive loyal (e.g., Rusbult, Johnson, & Morrow, 1986). The third dimension to characterize conflict management is engagement versus avoidance (e.g., Hocker and Wilmot, 1991 and Sillars and Wilmot, 1994). Engagement is reflected in direct, overt verbal confrontation of conflict issues, while conflict avoidance is reflected in withdrawal and aversion to dealing directly with conflict issues (Canary, Cupach, & Messman, 1995) and includes circumscribed, irrelevant, or ambiguous communication. Since the purpose of this study is to examine the effect of culture on marital conflict strategies and marital satisfaction, the discussion will be limited to the third dimension of marital conflict, engagement–avoidance, along with Rahim's styles of conflict.
Currently, one cannot explore the news without coming across the topic of the swine flu, scientifically known as H1N1. Swine flu is a respiratory infection derived from the influenza virus. The virus contains genetic materials from human, swine, and avian flu viruses. It was first identified in spring 2009, and since then has spread rapidly across the globe. The infection’s spread has been verified as a global pandemic by the World Health Organization. As soon as the swine flu virus was isolated, scientists quickly developed a swine flu vaccine. Four vaccines have been approved by the FDA for the prevention of the swine flu. The vaccines will be ready for distribution in October 2009. Now the question is: To vaccinate, or not to vaccinate? Millions of people are now preparing to answer this question.
It is a structure which consists of several bones which help protect the brain. It also helps support the structure of the face. There are two sections of the skull which enable this to take place and they are called the cranium and mandible. The cranium consists of 22 facial bones which are tightly compact with the mandible bones, giving the skull a strong structure. Small holes in the skull which are called foramina allow nerves and blood vessels to enter and leave the cranium.
Over the past century, the Burgess Shale has revealed important information about the development of earth’s history. The excavation of the Burgess Shale formation provided evidence for what was once just a theory in evolution. The taphonomic findings of the Burgess Shale have played a significant role in understanding the large diversity that resulted from the Cambrian explosion, advancing the study of evolutionary assemblages for Paleontologists worldwide.
Prior to the creation of state maintained schools and academies in Greece, higher education was mainly reserved for the elite persons of a community (Handbook: Greece 253). Training for these citizens consisted of instruction in the areas of music, poetry, numeracy, and religious ritual (Handbook: Greece 253).
Just like its namesake, Swine Influenza indeed was first discovered as a respiratory illness in pigs caused by influenza A (CDC.gov, 2016). However, variance in one or more genes in the virus, caused the mutation A/New Jersey/76, increasing the zoonotic effects of the virus (CDC.gov, 2016). The potential for humans to become infected now exist briefly perplexing immunologist and epidemiologist in its early stages. Transmission was linked to close respiratory contact with infected swine and or inhaling dust or hay infected with droplets of the
The pre-feminism concept of gender differences is captured by Harvey C. Mansfield: “Formerly society recognized the differences between the sexes, and with laws and customs accentuated those differences (435).” And indeed, accentuate them it did, as women were left without many opportunities enjoyed by their male counterparts. The absence of such opportunities, included voting rights, education, and property rights, is documented in Elizabeth Cady Stanton’s Declaration of Sentiments (411). Stanton does not speak to innate gender differences per se, but roundly testifies of the political injustice experienced by American women in the 1800’s. She shines the “equal station to which they [women] are entitled” through the prism of the Declaration of Independence, matching the inequality of women to men with the colonies to the English Crown, to reveal a sad portrait of female personhood (411-412, Italics mine).
Twenty-eight bones make up the skull. Eight of these bones are interlocking plates. These plates form the cranium.
According to the Swine flu investigation team on April 15 and April 17, 2009, novel swine-origin influenza A (H1N1) virus (S-OIV) was isolated from two epidemiologically unlinked patients in the United States. The same strain was identified in other countries such as Mexico and Canada. In the United States 60% of patients were 18 years of age or younger suggesting that the younger population was more susceptible to the transmission of S-OIV or the possibility that the older population had developed a small amount of antibodies from the 1976 swine influenza vaccine (H1N1). 18% of the patients had recently traveled to Mexico, and 16% were identified from school outbreaks. (France, Jackson & Schrag, 2010) The most common presenting symptoms were fever (94% of patients), cough (92%), and sore throat (66%); 25% of patients had diarrhea, and 25% were experiencing emesis. Therefore, the criteria characterizing the S-OIV infection are comparable to the ...
