Evolution By Natural Selection: One Of The Best Supported Theories In Science

212 Words1 Page

Evolution by natural selection is one of the best supported theories in science. It is the process by which species change over time as a result of changes in physical and behavioral traits. Changes that allow a species to better adapt to its environment, help it survive, and have more offspring(sexual selection). Natural selection can change a species in ways, causing a population to change color or size over several generations and create entirely new species.
Population genetics is the study of populations of a species change genetically over time, leading to a species evolving. For a population of species to thrive over time, it must have genetic variability and changes in allele frequency. DNA and genes. Population genetics provides the

    Many people have a misconception of Darwin’s natural selection theory, believing that nature specifically chooses the strongest organism of the bunch. What Darwin explains with this theory is that not the strongest organisms are the ones that manage to survive, but the organisms with the adequate traits are the ones that survive their environment. For example, if a lizard has the same skin color of the rocks in its environment, that lizard has a greater chance of surviving predators than lighter or darker color lizards. The lizard with the same color of the rocks may reproduce more because it is more suited for that environment than the other lizards. Roberto A. Frisancho explains that nature is the one responsible for natural selection, “Nature

    What is natural section? Natural selection is the process where organisms that can adapt to their environment tend to survive and produce more offspring. This process was discovered and proven by scientist Charles Darwin during the mid-1800’s. This process is key to science because it explains the central idea of how nature is designed. Natural selection is a key component to life on Earth.

    With respect to variations that are advantageous to survival, he notes that a slim wolf is more likely to run faster, catch prey and escape from predators. He also states that plants with attractive petals and sweet nectar is more likely to attract more insects that will serve as agents of pollination for that plant. Regarding variations that are useful for sexual section but not directly useful for survival in nature, he mentions brightly colored feathers in male birds and the ability to perform the mating call well. These traits, although useful for finding mates and reproducing might not be useful for escaping from prey. On the issue of isolation and natural selection, Darwin talks about organisms on islands and the importance of the weaker organisms dying out leaving those who are best suited for the environment to reproduce and ensure longevity of the species.

There are four conditions that explain why this happens: 1. Individuals within a population differ.

    Natural Selection is the long gradual process in which Biological traits either become more or less common in a population as a function of the effect of inherited traits on the differential reproductive success of organisms interacting with their environment. In Darwin’s work The Origin of Species he also mentioned evidence for the Theory of Evolution from his voyage around the world on The H.M.S. Beagle. The Origin of Species is probably the most influential work on evolutionary biology. The Origin of Species will help prove my thesis because it introduces the ideas that we base on evolutionary biology today.

    This process is known as natural selection, which explains how Charles Darwin’s theory of evolution can occur. Natural selection is an important component of evolution. It occurs when some members of a population are better fit for survival and proliferation than others in that population. The environment in which organisms live plays a large part in natural selection as well.

    Natural Selection is the process by which organisms that contain an array of traits that have a survival advantage in an environment tend to leave more offspring that can survive to reproduce in the next line of their lineage. Natural selection is a process that is observable which falls into the category of operational science. In short periods of time different organisms were observed. New species have also been observed to prove this theory. “Speciation is the process of change in a population that produces distinct populations which rarely naturally interbreed due to geographic isolation or other factors”.

    Three different sides will be discussed in this paper. First is the theory of natural selection, often called the survival of the fittest. Natural selection as quoted by the Merrium Webster Dictionary is, “a natural process that results in the survival and reproductive success of individuals or groups best adjusted to their environment and that leads to the perpetuation of genetic qualities best suited to that particular environment.” For example there is a litter of cats. One of these cats is a lot faster than the other cats and is therefore able to get food easier.

    I propose one simple question that, at current times, cannot be answered. Natural selection is the cause of evolution, guiding it where it needs to be, but why is this successful? As humans, we have not lived long enough to observe the process of evolution. Even if we realize its presence, we do not know why it happens. “Take bats, which have echolocation - they navigate by sound.

    Evolution is the theory that all living forms came from ancient ancestors. Through a series of mutations, genetic drift, migration, and natural selection today’s descendants show an amazing amount of similarities and diversity. Evolution on a small scale is called microevolution, relating to the changes that occur such as insects becoming resistant to pesticides. Macroevolution refers to the grand scale. It is associated with extinction, change, stability, and lineage.

    The theory of evolution claims that all species are arise from common ancestors. The basic part of natural selection is “the survival of the fittest”, according to Darwin’s theory. Different species living in the same space compete for limited resources, and the individual organisms that have the most advantage characteristics needed for survival are more likely to reproduce and pass down their generations compared to other species. Through natural selection, species adapt and change over time.

We both have had our genes selected for. Our genes have gained us the right to live on this earth at the current time. Our genetic makeup has allowed our ancestors to survive and reproduce allowing our genes to make us who we are today. If our ancestors lacked the proper genes for survival they would’ve perished and our genes would’ve been lost in history.
