Natural Selection Vs Genetic Drift

164 Words1 Page

1.Evolution is a changing process of all life forms, a trial that makes life adapting its living environment for survival. For my perspective, the difference between natural selection and genetic drift is the way of selecting genes. Natural selective is depending on outer environment. In the contrast, Genetic drift happens more randomly during evolution time. For the way of natural selection’s is a kind of adaption for living. As natural environment continually changing, some of organism’s genes may more appropriately adapt living environment. Therefore, only can creatures which obtain these “better” genes survive during the period of evolution. However, genetic drift reduces the diversity of creature’s genes. When a amount of life forms have

    Evolution, in common terms, is descent through genetic inheritance, with change in physical and biological characteristics. Evolutionary theory attempts to explain why we see so many species in world that seem so diverse and yet, have enough similarities that imply a common origin. There are various mechanisms by which evolution occurs, including natural selection, artificial selection, gene drift, etc., but in the end, evolution is process by which every single species that exists today, was derived from the last universal ancestor. This perpetual system of change and advancement, shapes the both the biotic and abiotic aspects of the environment, and results in the creation and advancement of the complex communities that inhabit the biosphere.

    Evolution is the process of change over time. It can be split in two questions, how did something living come from something that was not alive? And, how did things that were already living turn into other living things? Natural selection is when the “breeder: is the environment. This belief of natural selection came from Charles Darwin.

    Organisms can evolve to enhance their ability to catch prey, or flee predators. Coevolution occurs in a predator-prey relationship when the prey evolves in response to pressures exerted by its predator. The predator then evolves in response to the changes in the prey (or vice versa). Inheritable adaptive traits evolve through natural selection, the process by which organisms that have developed favorable traits are capable of surviving and reproducing at greater rates, thus passing their adaptive traits to their offspring. Birds and caterpillars have a predator-prey

  • Atavism: Charles Darwin's Theory Of Evolution

    In the article Atavism, the author explains the true meaning of atavism. The thesis of this essay is the theory of evolution that DNA can change over time. The author’s main claim is that atavism, a theory built upon Charles Darwin’s theory of evolution, is described as “the presence of characteristics found in remote ancestors but absent in other more recent generations.” The author argues this claim by stating, “The theory of evolution posits that DNA can change. These changes in an organism’s DNA can be good, bad or neutral.”

    Natural selection is about the struggle for survival of the fittest biological survival and the phenomenon to be eliminated. Organisms produce offspring, which is the basis of a species’ survival. They produce more than that can actually survive. Sometimes the environmental factors kill the offspring while other times it’s the disease or short of food. This makes every organism struggle to survive, which leads to the competitions of organisms against each other.

    Evolution How does new species derive? 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. Speciation by natural selection has been a topic of much debate for many years and the foundation of the evolution theory. The role of natural selection in speciation first described by Darwin has been widely accepted. Speciation remains to be up for debate.

Natural Selection is a term coined by Charles Darwin that is best defined as the biological enhancement that increases the chance of survival from generation to generation (Kobari).

    Depending on the conditions of the environment, the organisms may pass down selected traits to their offspring. These selected traits will allow for the next generation to better adapt and survive longer ["Natural Selection and Speciation - Biology."]. One example of evolution through the process of natural selection is that of the Viceroy butterfly. The Viceroy butterflies were facing extinction a little more than 100 years ago due to their inability to protect themselves or hide from their predators; mainly birds.

    Natural selection is a process in which whatever organism is better adapted to their environment tend to reproduce better offspring and become more fit. While natural selection is the most common type of speciation, it is not the only kind. The other type is Artificial selection. Artificial selection is when a human selects which plants or animals are allowed to reproduce. Most farmers and breeders use artificial selection so that their crop or cattle will produce better offspring.

  • Summary: The Evolution Of Non-Native Species

    1370 Words  | 6 Pages

    Well-documented records of introduction for non-native species provide a remarkable opportunity to understand how populations evolve in a new environment. Commonly, species introduced into a new environment came from a few individuals, which is translated mostly in a low genetic diversity due to that they have just part of the genetic diversity of the original population (Frankham 2005; Roman and Darling 2007). Additionally, the process of random genetic drift as it is predicted by the genetic theory is stronger in small populations (Frankham 1996; Roman and Darling 2007). Like further consequence related to genetic drift during the process of introduction, frequently is followed by a strong selection by the new environment what can drive an
