Sonic Seymorphism

Throughout the term, reading the book, “Through a Window” by Jane Goodall has been quite intriguing for me, in that it has inspired me with new ideas and perceptions about how our own species has evolved over time. I have really enjoyed seeing the many similarities that hominids share with other primate species, especially chimpanzees. Goodall’s research only further proves that we are not only extremely biologically similar to chimpanzees in our DNA, but have many behavioral similarities as well. The film, “Monkey in the Mirror” also shows support for our likeness in intellectuality. These documented findings on chimpanzee and human resemblances provides the strong evidence needed to conclude the fact that humans do indeed share a common ancestor with great apes.

These two features earlier are examples that we can see with our naked eyes, but the DNA make up that we cannot see with our eyes alone are also laid out the same as well. In the evolutionary pathway, the genes that turn on and off for humans and fish are related through the instructions on how they function. All living things with limbs have in common the Sonic hedgehog gene (Shubin, p. 53). The Sonic hedgehog gene can control the development of the limbs in these creatures. To determine if the development of vertebrate animals can be interpreted in the same way, or have the same effect, the injection of vitamin A was used to inject into a shark, mice, and chicken embryos to see if the results were the same. The results turned out that the injection of vitamin A has indeed changed the development of limbs in these embryos. The effects cause the shark to have a mirror image of its fin, and the mice and chicken have duplication of bones in the limbs (Shubin, p.56-57). It becomes clear of what will happen if

To begin this essay, Lovejoy appeals the notion of human uniqueness while focusing on human’s ability to be bipedal. By doing this, he introduces the possibilities of the first bipedal ancestor of humans while focusing the relation to other ape’s morphology. Lovejoy first discusses early Australopithecine as one the possibilities for a last common ancestor with chimpanzee, but quickly moves to Ardipithecus ramidus with their thesis of through examining the morphology and social behavioral structure of a CLCA , A. ramidcus can prove the African ape based models are not necessary. African apes models that are used to illustrate human and hominid behavior have become unreliable. To replace these models, Lovejoy proposes adaptive suites and explains

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 Lover by Marguerite Duras and Blood and Guts in High School by Kathy Acker are both transgressive novels and post modernist fiction. Both novels tell a story of a young girl in which is experimenting with her sexuality at a young age. In The Lover the narrator is in love with a man who is giving her money. Blood and Guts in High School is a fictional novel about the main character’s love for her father amongst other men. The goal of this essay is to explore the desires in which drive both of the young women’s sexual behavior that Duras and Acker express through their narrators.

The origins of anatomically and behaviorally modern humans is a prominent debate amongst paleoanthropologists. Ultimately, the two main ideas hypothesizing the origins of modern H. Sapiens are the Multiregional Hypothesis and the Out-of-Africa Hypothesis. The former states that all modern humans evolved from the H. Erectus that had once

In an attempt to find a correct phylogenetic tree, our group has found that Phylogenetic tree C shows a significant lineage. After researching, Phylogenetic Tree C seems to be an accurate depiction of hominid evolution. It shows a clear line of lineage that begins with the common ancestor A. Afarensis. To explain how the hominids connected in the lineage, our group decided to compare the skulls’ cranium width and length of braincase. We concluded that over millions of years, the width of the cranium of the hominids have increased, along with the length of braincases. Our explanation matched up with tree C respectively. The order of the width of craniums recorded are: A. Afarensis (80 mm), A. Boisei (80 mm), A. Africanus (85 mm), H. Habilis (98 mm), H. Erectus (108 mm), H. Heidelbergensis (122 mm), H. Neanderthalensis (128 mm), and H. Sapien

In this lab, section 3EG2 went to the American Museum of Natural History. At the museum, we gained more insight on human evolution, how fossils are dated using multiple techniques, and the evidence from fossils to reconstruct the hominid history. Human evolution states modern humans evolved from primates gradually from generation to generation over the time of millions of years and the H. sapiens (modern humans) are currently the only known descendants of the first known hominid (Lucy). To unmask the mystery surrounding this history, scientist have developed several techniques to estimate the age of fossils and their connection to the evolution. One technique scientists have used to determine the age of fossils is by observing the age of the

The rarity of human uniqueness no longer exists in the thoughts of scientists believing that human ability skills lie within the construction and use of tools. As declared by Goodall in which chimpanzees used straight sticks after removing the leaves and branches to collect termites or ants for consumption. (Goodall, 1986) Other species both primate and non-primate demonstrate successful abilities., which include a sense of self as well as the theory of mind, by which other species recognize that other individuals contain different information than themselves. Different species also have the ability to communicate symbolically to one another through the sounds of vocalization. (Sapolsky R. M., 2006)

Due to the many factors that we see in other mammals we don’t know why we classify ourselves as “human”. We basically have the same DNA as chimpanzees (that’s why we conduct experiments on them). Scientists just can figure out what really makes us different from everything else in the world. Paleontologists have found skeletons that resemble humans but are really linked to apes or other primates. For example we have the same tooth pattern but our jawbones are different. We have the same attributes to gorillas such as we have somewhere where we stay and also families. Our DNA and chimp DNA have been compared together and the match it gave was 95%. Although our form of communication of speech is better and improved other things in the animal kingdom also have their way of communicating an example of this is a wolf calling out or a whale calling a mate. We have our distinct feature such as we are hairless and we also stand up straight unlike our cousins the apes. We also dress unlike the other animals that are naked. And our brains are more advanced and bigger much larger than the ones in the animal kingdom. We also use many different things such as fire and tools unlike apes. Many believe this is why we are so much different from the other entire mammals that

Nathan Young, a researcher behind the study published recently in the Proceedings of the National Academy of Sciences,, highlights this fact in a news release in a news release. "We have features that clearly link us with African apes, but we also have features that appear more primitive, leading to uncertainty about what our common ancestor looked like.”

The theory of evolution essentially states how living species change over time. There are various ways species change, but most of them are based on the idea of Natural Selection, according to our text (Krogh, D., 2014, p. 307). Microevolution is a change in the recurrence of the alleles in a population process, which is reliable for the various changes or activity that varies from a norm or standard of some living species, like the examples of the finches (Krogh, D, 2014, p. 310). Microevolution happens on a small scale (within a single population), while macroevolution happens on a scale that transcends or go beyond the scope or limits of the boundaries of a single species. According to the diversity of species, evolution at both of these

The theories of human evolution may always cause a heated dispute. Each theory presents its own evidence proving

Human evolution according to research started over 6 million years ago. The outcome of the evolution process is the current human beings. Scientific studies have revealed over the years a remarkable affinity between the chimpanzees/Apes and human beings. Even though this reality is not a definitive prove that human beings evolved from apes, it does show that the human beings are in one way or another related to other primates. Scientists suppose that the humans and the primates shared a common ancestor. The subject of what makes humans what they are and their origin has been the exclusive purpose leading to many scientific studies globally (Coolidge & Wynn, 2011). Studies believe that Africa was the origin of evolution millions of years ago. Fossil remains have been discovered in different parts of Africa as well as other regions of the world. Different hominins have been discovered around the world in the last 1 million years. Thus, the different discoveries have led to comparisons between the various species of hominins to clarify on their similarities as well as differences. This essay seeks to explain whether they were distinctively different species or regional versions of the same species.
