The dictionary states that evolution is the process of developing growth. In the bible it is thought that god created everything we see today, from the land we walk on to the animals we interact with. Science claims that every living creature was made of an organism that changed over a period of time. To the current day some people continue to believe that the bible proves how we were created. Others, including myself feel that science evolved us from Apes to humans.…
Evolution does not occur by itself. It uses thousands of organisms that twist together to form all the life on this planet we call home. In our world, nothing exists in isolation yet everything is weaved together to form a complex system of evolutionary changes. In isolation, parasites could not survive and reproduce, plants could not spread their seeds, viruses could not infect their host, and organisms could not form adaptations from their environment that allow them to slowly evolve into better-adapted organisms. Parasites are organisms that need a host to survive and reproduce.…
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.…
The idea of evolution was once taboo for its new ideas at the time, it was seen as wrong because it challenged ideas already established about the world, especially how life came to be. Evolution is a relatively new idea discovered by Charles Darwin. This discovery came to be when Darwin was traveling along the Galapagos islands where he studied finches and discovered that these finches had all originated from one species of finch and eventually became differentiated leading the species to split, based on their environment. However evolution doesn’t just occur, it takes centuries or even millennia to take place and it isn’t the species that adapt to the environment, the environment selects those who survive. This means that only species with favored characteristics for that environment would be allowed to survive and produce offspring while those who do not have these favored characteristics would become extinct, dividing these species into more groups.…
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.…

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).…
A quick summary explains that evolution occurs over a long period of time (millennia upon millennia). It occurs when…
Evolution, as defined in (what is evolution), is change in the characteristics of living organisms over generations. Natural selection is used as a mechanism for evolution; organisms that are “picked” by natural selection evolve and pass on their genes. Drastic changes in environment, such as the nuclear apocalypse in The Day After, or the frigid blizzard-hurricanes in The Day After Tomorrow, can alter natural selection and by relation evolution. All catastrophes- natural or manmade- have a direct impact on the evolution of man as a species. Man can greatly impact natural selection in many ways.…
Evolution refers to change that occurs in a population over time. These changes are produced at the genetic level as organisms’ genes mutate in different ways during reproduction. Evolution is a change in the gene pool of a population over time. Populations simply adapt to their surroundings. Lots of things change over time.…
Ever since the beginning of time, natural selection has shaped our world. Natural selection, (also known as evolution), is the process of living organisms adapting and changing to survive in their natural environment. Many of the species that we know today have been involved in the process of evolution. Species don’t evolve like a flip of a switch, but are constantly evolving over a long period of time. As Darwin states, “Evolution occurs every 5,000 years”.…
Though evolution by natural selection is classically thought of as the speciation and adaptation of complex Eukaryotic life, when applied to Pathogens including Prokaryotes (Bacteria), simple Eukaryotes (Protist etc.) and Viruses, there is mounting evidence that these three groups undergo evolution by natural selection in ways that alter their virulence, symptoms and infectivity to increase their fitness. Though we can apply the principles of evolution by natural selection to the rapid changes in phenotype expression in pathogenic agents, their mechanisms for change - and the implications of these mechanism - are very different. In terms of sexually reproducing complex Eukaryotes, classical evolution by natural selection is a gradual change.…
All living organisms have evolved from a different species. Characteristics in a species change over time and the result is a new species. Biologists use evolution as a foundation to explain other questions that arise. Evolution by natural selection only occurs if the individuals within a species have some differences, the traits can be passed on to the offspring, and the offspring outnumber the available…
Evolution is a change in allele of species over time. An individual carries multiple traits from their parents allowing them to pass these genetics down to their children. This is the theory of evolution. The attend section gives a great example of the use of eyes and how these genes work. Evolution can be manmade as well.…
“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.…
