Brian Pobiner Theory

A theory is defined as “a plausible or scientifically acceptable general principle or body of principles offered to explain phenomena (Merriam-Webster, 2017). In the nursing field, nursing theories have helped shape philosophies of many nurses in our history, as well as modern day. Every nurse, near and far, could probably tell you who Florence Nightingale was. She was a pioneer for women in nursing and made countless contributions to our field. Her nursing philosophy was based on Environmental Theory, “A belief that a person’s surroundings such as clean air, water,

To illustrate, the theory of evolution by natural selection is the process by which organisms change over time as a result of changes in heritable physical or behavioral traits. Darwin was the first to formulate the theory and alludes to the fact that given enough time and enough accumulated changes, natural selection can create an

1. Evolutionary theory describes how populations change over time due to changes in the gene pool. There are several mechanisms that can change a gene pool and allow evolution to occur. Natural selection, mutation, gene flow and genetic drift are some of the driving forces behind evolutionary change. Natural selection and genetic drift are the mechanisms that decrease genetic variation, whereas gene flow and mutation are the driving mechanism to increase genetic variation. Natural selection is basically the understanding that the environment can not support unlimited population growth, and not all organisms are able to reproduce to their full potential due to trait variation. For example, a black fly may

The word evolution means the process of change over a period of time. For example: plants and animals evolve over time by their genetic system allowing them to adapt to different changes in the world. The theory of evolution states animals, insects, plants, humans, and etc are all from a one-celled ancestor. A bad example of evolution is having a bad diet, which does not pass on to your next generation.

The fifth part of the evolution theory is natural selection. Natural selection is an idea that life doesn’t require creation or guidance from a supernatural being. Natural selection depends only on nature in which the population will adapt to their environment while the one who are unable to adapt will die off. But natural selection cannot provide perfection but can only help the creatures to evolve just enough to be able to survive.

The definition of Evolution is ¨the process by which different kinds of living organisms are thought to have developed and diversified from earlier forms during the history of the earth,¨ (Dictionary.com, 2018). Although, the actual definition is hard to comprehend. Some consider Evolution to be a somewhat ridiculous topic that is far from true. Though others believe that, ¨Evolution by natural selection is one of the best substantiated theories in the history of science, supported by evidence from a wide variety of scientific disciplines, including paleontology, geology, genetics and developmental biology,¨ (Than, 2018). The main idea of Biological Evolution is that all life on Earth share a common ancestor. The term is a way of understanding life.

Darwin’s first theory of evolution first formulated in 1859, by which the organisms changed over time as a result of changes in heritable physical or behaviour traits. Changes allows the organism to better adapt to its environment will help it survive

There are many definitions to theory. According to Akers (2009) “theories are tentative answers to the commonly asked questions about events and behavior” (Akers, (2009, p. 1). Theory is a set of interconnect statements that explain how two or more things are related in two casual fashions, based upon a confirmed hypotheses and established multiple times by disconnected groups of researchers.

A theory is a set of systematic informed hunches about the way things work. A good theory goes beyond accepted wisdom and offers explanations and speculations about phenomena. Additionally, a good theory consists of a system of concepts which means that the theorist were able to make connections among his ideas. A theory tends to shape our perception of reality and behaviour and guides us through unknown areas.

The Theory of Modern Evolution states that organisms change over time as a result of adaptation to their heritable, physical or behavioral traits. These changes allow an organism to better adapt to its environment, help in its survival, and allow its offspring to survive. This theory was first introduced by Charles Darwin in his book, The Origin of Species. He studied finches in the Galapagos and discovered that the bird’s beaks change over generations depending on the type of seed that is available for the birds to eat. He concluded, after his

According to Haralambos and Holborn (2008), a theory is a set of ideas which attempts to explain how something works.

Evolution is a theory. It can refer to either a process or an organizing principle. Evolution is change. The process of evolution reflects on the definition as it applies to the population of organisms. A group of individuals of the same species that are subdivided from other populations is called biological population. A change in biological population is biological evolution. This change occurs over a course of generations. The evaluation changes are inherited by genes. Short-term changes are not evolutionary. Differential survival and reproduction of individuals in a population it's called Natural Selections. Brought about the evolution change. it is the process population adapted to their changes they're changing

The Theory of Evolution by Natural Selection, originally formulated by Charles Darwin in 1858, is the manner in which organisms change over time as a product of specific changes in hereditary physical or behavioral traits. This process provides the organism adaptations that assist and increase the chance of survival in the environment. (http://www.livescience.com/474-controversy-evolution-works.html) Today we can partially thank our existence to natural selection. “Survival of the fittest” is how organisms adapt and survive to the ever-changing environmental conditions, and those “fittest” survive.

A theory is primarily meant to explain or predict an event, behaviour or outcome. Proponents of a theory look for evidence to support the theory. This evidence should be independently observed and consistent after repeated observations. Some theories are speculative or ideas or guesses floated to encourage researchers to undertake the observations required to prove or disprove the theory. The question often debated is what comes

Charles Darwin's theory of evolution centres on the idea that species compete to survive, and favorable characteristics are passed on from one generation to the next. Darwin said that evolution took place by a process of natural selection or survival of the fittest. This meant that the animals and plants best suited to their surroundings survived and were able to pass on their genes to their offspring. The ones that weren't best suited died off and didn't get the chance to reproduce.
