Coevolution: Relationship Between Flowers And Bees

Great Essays
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,

    Evolution is a theory that every organism evolved from a lower life form. It is a belief first coined by Charles Darwin, an English biologist, naturalist, and geologist. Darwin also stated that instead of creatures being made for their environment, they progressed through a process called “natural selection”. Natural selection is the idea that organisms that are weaker either, adjust to their environment, or die off.…

    Evolution is how modern living organisms are related to ancient ones. Organisms have diversified and modified through ages and old one became extinct. According to Charles Darwin, all species have common ancestors. This means that, for instance, whales and dogs are related to each other by an old ancestor. Indeed, many organisms have common traits and characteristics, but this still doesn't mean that they are related.…

    For decades, scientists have conducted research on all living things; to help us determine what life is, what life does, and why things live. During life, several miraculous things take place, and among those things is change. Change that can start a chain reaction over decades, centuries, even millenia. We call these changes evolution. There are, however, several doubts in the minds of people; most commonly, those people who believe in the words of the Bible.…

    Evolution is the change in allele frequency in a population over time or, more simply, the process by which populations of organisms change over time (helped by the process of natural selection). Artificial selection does support this theory, except that the evolution happens intentionally, instead of naturally. Due to random mutations, variation within a population exists, allowing certain characteristics/genes to be selected as more favorable than others. Therefore, humans breed organisms with the favorable characteristics together to have offspring that might have the same characteristic. To do this, the characteristic has to have heritable genes so that the parent can pass the genes over to the offspring and increase the chance for survival in future generations, not just the individual (parent).…

    Escape and radiate coevolution necessitates the development of a trait or traits in one of the interacting species which provides an extreme advantage over the other and results in its rapid speciation into multiple lineages. The evolution of a particularly effective defense mechanism may render a species effectively immune to predation for a period of time, until a predator species counter-adapts in response, allowing for adaptive radiation unimpeded by predation (Futuyma). Escape and radiate coevolution is not confined to prey species however, predator species may also develop highly efficient traits which would allow them to freely exploit their prey species until they adapt to defend against it (Agrawal et al). The advantage that a species might develop would allow for a relatively short interval in which that species would experience adaptive radiation.…

    Genetic drift is a mechanism of evolution that occurs by random chance rather than natural selection. In genetic drift, a population experiences a change in the frequency of a given allele, prompted by random luck rather than a need for adaptation. This differs from natural selection, in which allelic frequency is altered based on the fittest genes surviving to reproduce and the weaker genes dying off. Genetic drift tends to be a phenomenon amongst smaller populations, while natural selection holds sway in larger populations. Life (168)…

    “It is no the strongest of species that survives, nor the most intelligent that survives. It is the one that is the most adaptable to change.” This quote was once said by the father of evolution himself, Charles Darwin who spent his life’s work on learning all he can about evolution. In the world we live in all organisms change, and were not the same thousands of years ago as they are today. There are two main theories to this process; scientific theory and religious theory.…
