In all the years that have past there is only ever been a few theories of evolution; evolution is how different organisms have developed or diversified from earlier ancestors in the history of the earth and is also known as the diversity of life. Evolution usually occurs very slowly, over long, extensive amounts of time. The idea of evolution can go as far back as the middle ages, because Aristotle explained all natural things are flawed and can be fixed in a natural way such as changing forms, ideas, or species.
The very first full-fledged theory was in 1809 by Lamark; it was called "transmutation", or the inheritance of acquired characteristics. He stated that all changes were just adaptation to the environment that animals sometimes made

This is when when two species in close interaction such as a predator and the prey they eat, herbivores and the plants they eat, or parasites and their hosts they feast off of. These species change to adapt from each other; this relationship can be deadly, mutualistic, or competitive. An example of a mutualistic coevolution is the relationship between flowers and bees; the bees fly from flower to flower to collect nectar which in turn pollinates flowers allowing them to reproduce. Competitive relationships happen when there is a limited resource and only the skilled organisms at getting that resource survive. An example of a deadly relation ship is wolves hunting rabbits; rabbits gains acute hearing to help sense the wolves, and the wolves gain enhanced smell receptors to hunt the rabbits. This is representation of how the diversity of life on earth is shown by the adaptations from interaction between two species in an environment ("Coevolution," …show more content…
A population 's allele frequency is the percent of offspring that can receive the trait. It may cause some genes or adaptations to disappear completely, and potentially reduce or completely stopping the genetic drift all together. The changes that are caused by genetic drift do not happen because of environmental or adaptive changes, and may be beneficial, mutual, or harmful to their reproductive success. It occurs at a faster rate when the population is smaller and in an isolated environment (The American Phytopathological Society, 2014).
There are a few ways that scientists have been able to prove evolution is real. The most popular and commonly known way is by looking at fossil records. They can be found in the form of a mold, cast, and imprint. When assembled and put in a panoramic view, fossil records are enough evidence of change in the organism 's structure for a scientist to be able to prove that it evolved over time. Then from there, scientists can determine the age of the fossil one of two ways. It can be determined by the layer of sediments it is found in and/or by radioactive dating(Scientific American,
