Patterns of Evolution

When it comes to natural selection there is pressure for all organisms that have reproduction. I just don’t think there is that much for humans because of the advantages that we have, such as brain functions which helps invent items for everyday living in different types of environments. Having a population with differences among the herd, there would be conflict on who fits better with the habitat and who doesn’t. For example, that is why there is so much prejudice, racism, war, and killings going on in the human environment. Just like in some animal species, if one of them doesn’t fit into their pack or have a deformity, they will more than likely kill them. The process of unrelated organisms evolving to become similar in appearances and behavior is known as convergent evolution. An example of these would be rodents that are distant relatives that live in the dessert. In divergent evolution closely related species living in different environments and facing different environmental challenges sometimes evolve dissimilar characteristics. Some of these bones make up human arms, dog limbs, horse legs, and bat wings. They all have the same origin, but all have very different morphology and very different uses. Adaptive radiation is where a number of species evolved from a single ancestral species. Honeycreeper which is a breed of birds found off the Hawaiian Islands is a great example of adaptive radiation. Then there is co-evolution which is the process by which two organisms become so well adapted to each other that they often limit other organisms from entering the equation. An example of this would be cheetahs and gazelle’s in Africa. They are both fast, yet still one is faster than the other, therefore the faster of the two uses the other as food. The one example that I choose for humans is co-evolution. Humans think that they are...

Patterns of Evolution

...Patterns of Evolution Dawn Austin SCI/230 January 28, 2011 Mrs. Sara Young Humans shape their environment in ways that other organisms cannot. Are humans subject to the same pressures of natural selection as other organisms? Why or why not? Yes, Humans are subject to the same pressures of natural selection like all other organisms. According to an article I was reading, the fact is that change in gene pool over time in all species is completely avoidable. Eyre-Walker and Keightley claimed that in 1999 that humans have had an average 4.2 amino acid altering mutations every generation since humans separated from the chimpanzees (, 2003). Provide an example of convergent and divergent evolution, adaptive radiation, and co-evolution. Adaptation radiation is an example of divergent evolution. Divergent evolution is the process of two or more related species becoming more dissimilar. An example of divergent evolution is; the red fox and kit fox, the red fox lives in forest and farm lands where its red color helps it blend in with surrounding trees. The kit fox lives in the plains and in the desert where their environment is sandy and their color help conceal them from prey and predators. The ears of the kit fox are larger from the red fox. The kit fox ears are an adaptation to its desert environment. The enlarged surface area of its ears help the fox get rid of excess body heat. The red fox and the kit fox have similarities that suggest that they had......

Patterns of Evolution

...Patterns of Evolution Humans are still subjected to the same pressures of natural selection as other organisms because we also compete for sources of food as our society becomes over populated while adapting to environmental concerns, such as global warming with radically different changes in climates, contaminated water sources, or other forms of pollution. Survival of the human race will require reproduction to avoid becoming extinct, thus ensuring the perpetuation of favorable traits in preceding generations. Biologists have recognized that patterns of evolution exist and can vary because every species is unique. Convergent evolution is unrelated organisms living in similar environments, which can evolve with similar characteristics, such as the example of a hurricane can look and feel the same, whether it occurs in Florida or Italy. Divergent evolution, species living in different regions that were closely related, yet perhaps drifted apart, such as the example of the polar bear and the brown bear. Polar bears developed new characteristics because they needed blubber to keep warm in the snowy climates in comparison to the brown bear. Adaptive radiation, several species move into a new territory and evolves into a completely new species, which began from a single species, such as the marsupials – kangaroos with powerful, long legs to cover large areas of land, and koalas with smaller, centralized bodies allowing them to climb trees. Co-evolution occurs between......

Evolution of Management Thought and Patterns of Management Analysis

...MANAGERS AND MANAGING What is Management? "Management is the organizational process that includes strategic planning, setting objectives, managing resources, deploying the human and financial assets needed to achieve objectives, and measuring results. Management also includes recording and storing facts and information for later use or for others within the organization. Management functions are not limited to managers and supervisors. Every member of the organization has some management and reporting functions as part of their job." (Knowledge Management Terms, 2009) Essential Managerial Tasks A manager's job uniquely describes the functions of management, which are most commonly cited as planning, organizing, leading, and controlling, although some managers' jobs identify additional functions. The process of management is defined by the functions of management, which are distinct from accounting, finance, marketing, and other business functions. " These functions provide a useful way of classifying information about management, and most basic management texts since the 1950s have been organized around a functional framework." (Cengage, 2006) Levels and Skills of Managers Most organizations have three levels of management. First-line, middle, and top managers. While first-line managers are responsible for the day-to-day supervision of non-managerial employees, middle managers are responsible for developing and utilizing organizational resources......

Organisations are therefore driven to continuously adapt their business processes to new conditions. Thus, management of business process schema evolution, particularly process version control, is in great demand to capture the dynamics of business process schema changes. This paper aims to facilitate version control for business process schema evolution, with an emphasis on version compatibility, co-existence of multiple versions and dynamic version shifts. A multi-level versioning approach is established to specify dependency between business process schema evolutions, and a novel version preserving graph model is proposed to record business process schema evolutions. A set of business process schema updating operations is devised to support the entire set of process change patterns. By maintaining sufficient and necessary schema and version......

Misrepresentations Of Evolution

...scientific finding, there are always misconceptions surrounding it. Mainly, the media might portray the finding in an uneducated way. For evolution, certain measures have to be taken when writing about it in classroom textbook. Because of decreasing state support and increasing political factionalism, writers have a harder time composing a textbook that presents adequate scientific material. In Padian’s article about the misrepresentations of evolution in textbooks and the media, he not only talks about the process, but also about how to address scientific research and statements. It is overwhelming for writers to keep up with new research that contradicts traditional material or if it will be changed in a couple of months. It is...

Theory of Evolution

...Theories and the Theory of Evolution Joy Dawson Colorado Technical University Author Notes This paper was prepared for SCI 101- 1401A taught by Professor Scott Christensen on January 17, 2014. Theories and the Theory of Evolution Evolution, a natural selection theorized by Charles Darwin and backed by many other scientist based on the scientific method. All theories must be capable to conduct testable predictions. Predictions are performed by observation and experimentations that are then to be conducted to give the theories authentication to the predictions. Darwin theory depends on slow, consistent, gradual change in organisms which in time will become a new species. Other evolutionary theories propose that evolution occurred in rapid periods of time or that a designer intervened during different times to modify or create organisms. The controversial debate of punctuated equilibrium and phyletic gradualism still exists, but the interesting research continues with fossil records, patterns of punctuated equilibrium, and maybe even more with the use of innovations of today. It is safe to say that scientists agree there is two models of growth which theorizes evolution of species can emerge. A species can change by phyletic gradualism and punctuated equilibrium or both. Scientist believes species with a shorter evolution change is mostly by punctuated equilibrium, however, those with a longer progression developed mostly by gradualism. Phyletic gradualism happens......

...Sociobiology is a field of scientific study which is based on the assumption that social behaviour has resulted from evolution and attempts to explain and examine social behaviour within that context. By claiming a more biological route it explains that the behaviour of both humans and animals are due to biological and evolutionary factors. Sociobiology is mostly interested in the evolution of physical structures and is more genetic control orientated therefore differentiating it from evolutionary psychology. The focus on adaptation and reproductive success rather than progress toward perfection is made most clear through the work of sociobiologists like Edward O. Wilson. Adopting a focused approach to the understanding of behaviour on the genetic level, Wilson saw social behaviour as being controlled, in principle, by particular genes. Evolution and human behaviour from a sociobiologists view point occurs as a result of genetic determinism, reflexes, habituation, Fixed Action Pattern’s (FAP’S) and complex social behaviour. Sociobiologists would argue that just as selection pressure led to animals evolving advantageous ways of interacting with the natural environment, selection pressure also led to the genetic evolution of beneficial social behaviour.. Take for intense a sociobiologists view on genetic determinism. Genetic determinism is the belief that genes and environmental conditions, determine specific  structural features and behavioural phenotypes or observable......

The theory of economic development throughout history has been of significant discussion especially in regard to the works of Rostow and Gerschenkron. The differentiation between the pattern of thoughts and ideals is a hotly debated topic within economics. The ideals the two theorists create, each substantially creditable in their own right, entail degrees of correlation and variation. Leaving the conclusion, do the to patterns of economic thought complement one another or is there distinct disparity between the two.   Applied examples will be used below to analyse the extent of segregation or association between the works of Rostow and Gerschenkron.

Beren Robinson’s Field Study

...Beren Robinson’s Field Study The field study by Beren Robinson is an exceptional study of threespine sticklebacks, which relate to ecology evolution. The original findings of researchers differ from Robinson’s field study. Robinson’s hypothesis states the threespine sticklebacks diverse phenotypes are the creation of natural selection supporting the discrepancy in the population. The variables in the study are diet and environmental conditions. Ecologists use evidence and observation to quantify results by using information from other studies and experiments. Robinson’s field study relates to evolution and natural selection, and each play an important role in ecology. Robinson’s field study should alter variables of life span, growth rate, and body size to understand the evolution of the threespine stickleback species. Original Observations of Researchers The field study by Beren Robinson is a study to determine how the threespine stickleback species of fish have evolved. The threespine sticklebacks went through an increased era of time. Only two species of threespine sticklebacks inhabit in a lake. Original observations of researchers suggest that opposing selective pressures in open-water and shallow water are factors in the evolution of the threespine sticklebacks (Smith & Smith, 2009). Robinson’s study proves a different analysis and suggests natural selection is a key factor. The study by Beren Robinson and the department of Zoology at the University of Guelph...

This week we are doing an assignment on teach back and I have chosen Biodiversity. I have found some great information on biodiversity but before I can go any further I need to understand what biodiversity is. What is biodiversity? Biodiversity means the diversity, or variety, of plants and animals and other living things in a particular area or region Biodiversity may also mean the number, or abundance of different species living within a particular region. There are three kinds of biodiversity that are there to preserve our systems. First we the genetic diversity, species diversity, and lastly the ecological diversity. When looking at on how the species in diversity arise we would look at the surrounding areas and the climate that affect the species. There are many species in the ecosystem and when something such as climate change you will have a problem in your food change, water sours. When this happens it will be harder for the species to survive since they are being deprived. The patterns of biodiversity begin with community structure, which begin with the climate and ecosystems. There is a list of patterns that affect the earth of biodiversity; there are hotspots as they are called and cold spots (high and low). Along with the patterns there are the relationships between local and......

Examining Evolution from Two Subfields in Anthropology

...Examining Evolution from Two Subfields in Anthropology ANTH 101 Professor Rosh March 25, 2012 Evolution overall is the change and adaptation of all living things on this planet. In the past this idea was thought to be absurd and still in today’s society some people still don’t believe in the theory of evolution. Thanks to a man named Charles Darwin who was brave and smart enough to publish scientific books on this subject some of our society now accepts the concept and studies it. To think that living species does not change and adapt over time is nonsense. With the study of evolution humankind can learn from its past and better prepare for the future by studying how humankind has developed over the past. Evolution is defined in biology as the idea that all species can change over time and have a common ancestry (Parker, 2008). A physical anthropologist could study primatology in order to study evolution for humankind. Primatology is the study in physical anthropology that began with morphological comparisons of primates to reconstruct the evolution of humans (Rodman, 1999). Studying primatology can help the study of evolution because it is a very good example of basic evolution and primates and human beings have a lot of similar traits and also the primate is the closest living example that is like a human genetically. This source was chosen because it helps break down the meaning and understanding of primatology and provides the basics and in depth terms......

...Secularism A Religion Profile from International Students, Inc. Secularism: An Overview Number of Adherents Demographer Davit Barrett estimates that there are 150 million atheists and 768 million nonreligious people in the world. The combined total comes to more than 918 million people (Barrett). Toward the end of the Renaissance, the modern method of empirical science began to develop. The key players were Nicholas Copernicus (1473-1543), Johannes Kepler (15711630), and Galileo Galilei (1564-1642). Although it may seem ironic now, each of these men believed in the Christian God. They viewed science as studying the handiwork of an almighty Creator and discerning His natural laws. Galileo considered God to have written two “books”: the Bible and nature (Hummel, p. 106). Contrary to popular belief, the cause for the diversion between Christianity and science originated not with the Church but with the university professors who were threatened by Galileo’s revolutionary ideas. These professors were steeped in the Greek scientific method, which included observation to a small extent, but mostly explained the workings of nature through rational deduction from first principles, or assumptions, an entire view of the universe had been built up. Consequently, the professors embraced such misconceptions as the sun having no imperfections, the moon being a perfectly smooth sphere that shone with its own light, and the earth alone having a moon since the earth was at the center of......
