Explain How Is A Theory Different From A Hypothesis

The environment determines which traits are most evolutionary desirable to an organism. If a population should move or should the environment change, a different set of traits would be the most advantageous

Hypotheses are often taken from a form of an if-then statement (Scott 2009) -- usually based on previous experience, scientific background, observation, and logic. While a scientific theory explains laws and facts (Scott 2009). Clearly, this is a contradiction. A hypothesis cannot be considered as a scientific theory since it is based on conditions that simply lacks a strong foundation to become a theory unless it’s proven to be concise otherwise.

In the process of natural selection, individuals that have certain inherited traits tend to survive and

According to Dr. James Krupa of The University of Kentucky “evolution is the foundation upon which all biology rests.” In biology, evolution is the genetic change in characteristics over generations and is dependent on the process of natural selection. ‘The theory of evolution is based on the idea that all species are related and gradually change over time’ (Genome Campus, 2017). Genetic variation is vital to evolution as it affects the physical characteristics or phenotypes of morphology. Natural Selection is affected by environmental factors that act upon a population and result in the mutation of organism through offspring. These mutations enable individuals to adapt to their environments in order to survive, find food, avoid predators and

Evolution is the process of biological change by which descendants come to differ from their ancestors. Natural Selection is when an individual with the best trait survive and breed in more population. Larger populations of organisms with the desired traits will then occur and organisms will evolve. The four principles of Natural Selection are variation, over production, adaptation, and descent with modification. Charles Darwin, an English naturalist and geologist saw two major trends within organisms which were variation and adaptation. Variations are differences in individuals’ physical traits compared to other individuals. In the Galapagos Islands Darwin noticed that finches had different beak sizes and shapes. Darwin then concluded that finches with thicker beaks lived in areas where nuts were the main food source and finches with smaller beaks tended to live in areas where insects were the main food source. Adaptation are features that allow an organism to better survive in their environment. There has been many adaptations in animals but one of the best has been living in groups because animals can then “help each other find food, defend against predators and care for their young” (animalpanet, n.d.). Overproduction is when organisms produce more offspring than the environment can support. Darwin stated that all animals over produce since offspring can reach reproduction age and have offspring of their own. For example, “even a slow breeder

Natural selection involves the adaptation of a species to better survive in their designated environment. When organisms reproduce, they pass down their DNA to their offspring. For example, a child that is tall is the result of their parent being tall as well. Parents pass down traits to their children. When it comes to survival, some organisms are better at it than others based on the traits that they have acquired. Some organisms can camouflage from predators while members of the same species do not obtain that same trait. With that in mind, the ones that can camouflage will most likely survive in certain environments and they will then pass on that trait when they reproduce. Since these traits are advantageous, they are passed on to more and more offspring through time and it will eventually overcome any original traits that species first started out with. It’s kind of like the current state of sexual misconduct in Hollywood. We have our directors, actors, agents, and so forth. However, as time goes on, some do not survive in the business based on their inherently evil traits and they get weeded out just like some species in the wild. As generations pass, these organisms have then adapted to fit the environment and better survive based on their inherited traits.

The descendants of the species have been given changes from their ancestors. This is called natural selection. Natural selection is a type of evolution that animals go through when there is a hardship in their natural habitat. Most animals go through natural selection to survive, they can pass it on to their kin.

Generally, theory and hypothesis are often used interchangeably but they are two separate factors of a research study. A theory summarizes information about an occurrence and organizes this information serving as a source for predictions. Researchers then deduce the theories into a hypothesis that is to be tested through objective observations.

Natural selection is the evolutionary process by which heritable traits that best enables organisms to survive and reproduce in a particular environment are passed to ensuing generations. Organism within the same species may develop new characteristics based on their environment to ensure their survival. The new genetic development within the species maybe then passed on to their offspring. Those within the species that do not develop a new characteristic to adapt to the altering environment are left prone to disease, deformities, and even death or extinction.

(a.) A scientific theory has two components; a pattern, and a process that creates the pattern. A hypothesis is a testable statement that explains a phenomenon of a set of observations.

Natural selection is the process where organisms that have more advantageous adaptions that benefit its survival in its environment then breed and produce offspring with similar traits that then have a greater chance of survival. For natural selection to occur there are essential elements that are required; variation, heritability and excess production. For the formation of a new species there must be variation within a species so that some may have slightly better adaptions to the climate, diseases or other survival traits like better camouflage. The organisms that possess these adaptions are sometimes called more fit; this is called ‘survival of the fittest’. The ‘fitter’ organisms will then reproduce and their offspring will inherit the

Theories come after the observation of the fact. Theory is a proposed explanation to understand something and the fact is the something that can be observable or something that is

2. Theory simply means we come up with a problem, and we look for a solution. A theory is a series that tries to

Evolution depends on both inheritance and selection (Arnold, 1994). Heritable traits having some advantage to an organism must be passed on from one generation to the next. As a result, the organisms that have inherited these traits will be better suited for survival in a specific environment. In other words, the ability for an individual to survive is not enough to fuel evolutionary progression- there must be reproduction taking place as well (Figure 1).
