Evolution Questions Answered - 741 Words

Evolution Big Idea Project Chris Berg There are many people that are not fully informed about the concept of evolution. Because of this, they are unable to make scientific and logical connections between us humans and how we evolved from the world around us. There are a broad number of misconceptions that people have, but I decided to focus on 3 major ones: 1. Evolution is goal oriented. Many non-evolutionists say that if evolution existed, there would be some endpoint or â€Å"goal† that is reached. In other words, species are trying to become perfect. However, that is not the case. Every species is only adapting and evolving to fit their current needs and to thrive. They change because of environment, available nutrients, to stay†¦show more content†¦Closely related organisms have very similar DNA. It turns out humans share over 90% of the same DNA with ape-like creatures. We can conclude that they have a relatively recent common ancestor. Another way to determine the relatedness of two organisms is finding fossils of a species that displays an intermediate stage between the two existing ones. This intermediate species most likely became extinct, but not before some of them evolved even more towards humans. The proposed common ancestor between humans and apes is likely an extinct species named â€Å"Pan Prior† . It gets pretty in depth from there, but there is no current fossil existing of it, but analysis of its DNA shows many signs of a common ancestor. It most likely existed 8 million years ago. The ape is the most closely related living organism to the human. It is evident that species so similar must have a common ancestor. 3. The eye cannot evolve from natural selection When evolution skeptics want to attack Darwins theory, they often point to the human eye. How could something so complex have developed through random mutations and natural selection, even over millions of years? Although there are only a few examples, there is evidence of an eye changing slowly overtime due to the advantage it gave. Most likely, the eye only started out as a light-sensitive patch on the head of an organism. That patch must have given that organism some sort of advantage. Slowly, the eye became deeper and more open.Show MoreRelatedThe Evolution of Evolution1188 Words   |  5 Pagescreation of humanity have rapidly changed since the discovery of evolution.

Introduction Ultrasonic machining is a non-traditional machining process. USM is grouped under the mechanical group NTM processes. Fig. 9. 2. 1 briefly depicts the USM process. Force, F Slurry of abrasive and water Horn Vibration frequency f ~ 19 – 25 kHz Amplitude, a ~ 10 – 50 ? m Tool Work Fig. 9. 2. 1 The USM process In ultrasonic machining, a tool of desired shape vibrates at an ultrasonic frequency (19 ~ 25 kHz) with an amplitude of around 15 – 50 ? over the workpiece. Generally the tool is pressed downward with a feed force, F. Between the tool and workpiece, the machining zone is flooded with hard abrasive particles generally in the form of a water based slurry. As the tool vibrates over the workpiece, the abrasive particles act as the indenters and indent both the work material and the tool. The abrasive particles, as they indent, the work material, would remove the same, particularly if the work material is brittle, due to crack initiation, propagation and brittle fracture of the Version 2 ME, IIT Kharagpur aterial. Hence, USM is mainly used for machining brittle materials {which are poor conductors of electricity and thus cannot be processed by Electrochemical and Electro-discharge machining (ECM and ED)}. 2. Mechanisms of Material Removal in USM and its modelling As has been mentioned earlier, USM is generally used for machining brittle work material. Material removal primarily occurs due to the indentation of the hard abrasive grits on the brittle work material. As the tool vibrates, it leads to indentation of the abrasive grits. During indentation, due to Hertzian contact stresses, cracks would develop just below the contact site, then as indentation progresses the cracks would propagate due to increase in stress and ultimately lead to brittle fracture of the work material under each individual interaction site between the abrasive grits and the workpiece. The tool material should be such that indentation by the abrasive grits does not lead to brittle failure. Thus the tools are made of tough, strong and ductile materials like steel, stainless steel and other ductile metallic alloys. Other than this brittle failure of the work material due to indentation some material removal may occur due to free flowing impact of the abrasives against the work material and related solid-solid impact erosion, but it is estimated to be rather insignificant. Thus, in the current model, material removal would be assumed to take place only due to impact of abrasives between tool and workpiece, followed by indentation and brittle fracture of the workpiece. The model does consider the deformation of the tool. In the current model, all the abrasives are considered to be identical in shape and size. An abrasive particle is considered to be spherical but with local spherical bulges as shown in Fig. 9. 2. 2. The abrasive particles are characterised by the average grit diameter, dg. It is further assumed that the local spherical bulges have a uniform diameter, db and which is related to the grit diameter by db = ? dg2. Thus an abrasive is characterised by ? and dg. db db db db dg Fig. 9. 2. 2 Schematic representation of abrasive grit Version 2 ME, IIT Kharagpur During indentation by the abrasive grit onto the workpiece and the tool, the local spherical bulges contact the surfaces and the indentation process is characterised by db rather than by dg.

The contact zone is circular in nature and is characterised by its diameter ‘2x’. At full indentation, the indentation depth in the work material is characterised by ? w. Due to the indentation, as the work material is brittle, brittle fracture takes place leading to hemi-spherical fracture of diameter ‘2x’ under the contact zone.

At the age of nineteen he first experienced LSD which lead him to experimenting more with marijuana and LSD. At the age of twenty one he was arrested for possession of marijuana. At the age of 21 at a family dinner he started showing signs of schizophrenia which was aggravated by drug abuse. At the age of twenty two Herbert Mullin began treatment as a resident of the community drug abuse prevention center in Santa Cruz. Later that year Herbert Mullin was committed to the psychiatric ward of San Luis Obispo County General Hospital because with is mental disorder he was a danger to others, himself and gravely disabled. A month later he was diagnosed as a paranoid schizophrenic. He was not one that cared to take his medication. In the summer of 1970 he was diagnosed as a schizo-affective schizophrenia. In 1970 he began blaming his parents for his illness and in result took them out of his will. Herbert killed people believing that if he started to kill people it will lessen the chances of another hurricane happening in his area. He did this by only killing random Caucasians from the age of 4 to 72. He bought his materials to the crime scene such as a gun, knife, and baseball bat. He was a psychotic visionary. Mullin had no developmental problems according to Erikson. He went through all the stages where he experience love and finding out what personality he wants to embrace. This is the point and time when he realizes that he is a bisexual. The motivation behind it seems to be the fact that he was born the day that Albert Einstein died and the anniversary of San Francisco Earthquake. Freud would have said that he is anticathexis because he gives off the sense that his ego is blocking the socially unacceptable needs of id. Mullin for example when he found out that his target moved he went after him and killed him as planned. Afterwards he couldn’t resist the urge to go back and kill the messenger who could have been a witness in the killing incident that happened before her and her family. Bibliography * Watts, Vernetta.
