The picture of the cover of the magazine features Tiktaalik, a creature that is intermediate between fish and primitive land-living animals. Tiktaalik has fish-like characteristics with scales on its back as well as fins with fin webbing. However, it also has a flat head and a neck similar to early land-living animals. Inside the fin, one can also see bones that correlate with the parts of the wrist, forearm, and upper arm. All of this is inside a fin with webbing. Shubin once dissected a cadaver, but was never emotionally attached to it until he dissected the hand. It was when he unwrapped the hand did he come to the realization that this hand once belonged to a living person who used it to move and touch. Later on in his career, Shubin discovered Tiktaalik which revealed the early stages of the parts of our hand evolving: the finger area, palm, and wrist. Shubin expressed that seeing the wrist of a fish was just as worthwhile as unwrapping the fingers of the cadaver because during both times, he uncovered a deep relationship between his humanity and another being. Sonic hedgehog is a gene named by fly geneticists Tabin, McMahon, and Ingham. The name was given to the chicken version of hedgehog because the flies with a mutation in the gene possessed bristles and this reminded them of a hedgehog. In …show more content…
In humans, the first arch forms the upper and lower jaws, the malleus and incus, and all the vessels and muscles that supply them. The second arch forms the stapes, a tiny throat bone, and the majority of the muscle that control facial expression. The third arch forms the nerves, muscles, and bones located deeper in the throat that is used for swallowing. Lastly, the fourth arch forms the larynx and the surrounding muscles and vessels that help it function
3. What did further examination of Tiktaalik’s fins reveal about the creature and its’ lifestyle?
In 1983 a male killer whale was captured in the North Atlantic. Already at 2 years of age he was 11.5 feet long and was named Tilikum. Once he was shipped to Sealand of the Pacific, Tilikum was put in a pool with a trained Orca and both were given the same orders. If both didn't follow through with it both were punished by food deprivation. Since Tilikum couldn't follow these orders because he had no training before, they were not given food. Due to this, the bigger female Orcas out of frustration would gang up on him and leave rake marks. Also would be attacked when left in their pool enclosure at night.
Hedgehog is a gene active in ZPA. ZPA is only located in little clusters and with this hedgehog gene, it creates a mirror image in limbs for the development and growth. The gene creates digits that are clearly different from one another depending on how close they are to the ZPA. The chicken version of the hedgehog gene was named Sonic hedgehog and it activates once Vitamin A is injected. All creatures have the Sonic hedgehog and they all can be activated by injecting Vitamin A. When tested on a skate, the Sonic hedgehog turned on at the same time as a
The magazine cover is Tiktaalik which is a very famous fossil that is the first to show aquatic creatures becoming more associated with being on land and adapting. Tiktaalik is the first cross between fish and tetrapod. The chapter speaks of all the necessities and struggles of uncovering fossils and the wonderful things discovered by them, such as the fact that Tiktaalik is over of the first creatures that showed similarities
Each year, the FBI provides research on law enforcement officers that have been killed or assaulted; many people know this as LEOKA. The goal of this data is to provide people with information through the UCR (uniform crime report) about law enforcement officers who have been feloniously and accidently killed, and also officers who have been assaulted in the line of duty. The uniform crime report presents this information through overviews and statistics about each of the victims, where they come from (the state they resided in), and also when and how they were killed. Throughout the years this has become an effective way to research and learn about this topic and understand why it is important to know about. Throughout this paper I am going to find patterns through different regions and states in the United States under all three of the topics LEOKA focuses on and find similarities and
The Nacirema is a North America group who lives around the area of Canadian Cree, the Yaqui, Tarahumare of Mexico, the Carib, and Arawak of Antilles. The ritual activity is a big part in the Nacirema's lives. They spend a considerable amount of time performing a secretive ceremonies and posses a great amount of tolerance. Their focus is on the human body appearance and health. It is to their believe that human body is viewed as ''ugly'' and ''debility and disease.” Hoping to eliminate those undesirable characteristic traits, the Nacirema's only hope is to do so through ritual activities hence the shrine is built inside of every house.
As hunters across the state venture out into Alaska's forests and tundra in hopes of filling their freezer with moose meat, hunters in the Lower kuskokwim have bit the bullet and hung up their rifles. They are entering the first year of a self-imposed five-year moose-hunting moratorium they hope will significantly improve their moose hunting in the future.“The main stem of the Lower Kuskokwim is one of the few places left in Alaska that has outstanding moose habitat and extremely low numbers of moose,” said Roger Seavoy, the Bethel area biologist for the Alaska Department of Fish and Game.
Miner (1956) discussed the body rituals among the Nacirema. The Nacirema are human beings, just like all other humans. They bleed, they love, they are born, and they die. However, for some reason, the Nacirema consider themselves a special breed of humans. This belief is so ingrained in their traditions and cultures that some have taken it to the extreme. Scholars have argued that the Nacirema’s inflated sense of pride stems from the greatness of their ancestors. They descended from a great group of warriors who came together and agreed on the future of their descendants. This essay will examine the Nacirema’s obsession with oil and how this informs their aggressive behavior.
Rikki-tikki Tavi took place in India in the late 1800s. Rikki-tikki Tavi was a brave, little mongoose who killed copra’s and Karait a venomous snake and saved a family from the snakes. Darzee, the tail-bird, helped him, and Chuchundra, the musk-rat, who never came out into the middle gave him advice but Rikki did the real fighting. When Rikki-tikki was first trying to kill the copra he was scared, but then he remember that mongooses are known to fight and kill snakes. Rikki-tikki and the copras are natural enemies. Every time when Rikki-tikki would fight his eyes would turn red and fierce.
As we know inadequate living conditions and unfair treatment is what animals in captivity face day by day. How do you think this affects the animals? It affects their behavior; from become sad and depressed onto becoming aggressive and violent. For example; the story of Tilikum, the orca. During his life, Tilikum, the largest orca in captivity, weighed 12,500 pounds and measured over 22 feet in length.
During the Holocaust there were many death camps, but do you know exactly what happened to the people in those camps? Understanding what the Treblinka camp was like, where it was, the amount of people that died, and if there were any revolts may give us a better insight of the camp itself.
Explain why Neil Shubin thinks Tiktaalik says something about our own bodies? (in other words – why the Inner Fish title for the
During the Renaissance it was expected of women to be married off and then perform their duties as wives and mothers. Women were not allowed to hold any occupation outside of the home. I think joining a convent was an alternative to marriage because that was where women could learn how to read and paint, and where they could participate in activities that have been denied to them. Many women artists only used their first initial when signing their works so that they were not identified as women. Suor Plautilla Nelli fir example signed her works "S. Plautilla". Plautilla is the first known female painter in Florence who entered the Dominican convent of Santa Caterina da Siena in 1538. She studied and copied works from Agnolo Bronzino, Andrea
Towards the end of the Neolithic era, climates changed and populations increased causing the universe to abandon nomadism and adapt sedentism. Eventually, humans found themselves in the trap of sedentism and all of society was dependent on agriculture. As agriculture became more complex and populations continued to increase, the earliest forms of towns developed. The towns of Jericho and Catalhoyuk became the first known towns of the world. Jericho was dated to arise around 9000 – 8000 BCE. The people of Jericho lived in close quarters, mud-brick houses, and began showing signs of power with evidence of decorated burials. In Catalhoyuk, houses were also small and close in proximity. Jericho had a population of about 2,000 people, but compared
Sokdokpa Lodro Gyaltsen is, among several others, one of the most peculiar figures of the history of Tibet. He was born in 1552 in the province of Tsang, which are two significant datums because Sokdokpa’s life and career was deeply influenced by the sociohistorical circumstances of his time. Sokdokpa, largely acknowledged in the traditional Tibetan spheres for his thirty-two years endeavour to rid Tibet of Mongols, is credited within the Nyingma School as one of its finest exegetes and ritual masters, exerting an influence on the cultural level of his epoch that was dramatically curtailed subsequently by the Fifth Dalai Lama – a deed that conspicuously signals the relevance reached at that time by
