Natural Selection: A Process Of Adaptation

Words: 279

Pages: 2

Natural selection is a process of adaptation that happens over time, which allows the most favorable traits to survive according to the circumstances. An article based on biological evidence of natural selection in the intraspecific eye color variability in species by Negro, Blazquez, and Galvan (2017) shows an evolutionary phenomenon in humans and domestic animals with light-colored eyes occurred about 8,000 years ago in northern Europe during the early development of human civilization. The authors propose two hypotheses in which wild animals mostly result in non-variant eye color, whereas humans and domestic animals appear to have variant eye color. The first hypothesis suggests that natural selection allows wild animals to adapt according

Evolutionary Selection Vs Natural Selection

Natural selection is one of the central mechanisms of evolutionary change and is the process responsible for the evolution of adaptive features. The term adaptation is the process by which populations of organisms evolve in such a way as to become better suited to their environments as advantageous traits become predominant. It is also how physical, physiological, and behavioral features that contribute to survival and reproduction arise over evolutionary time. Natural selection by itself is incapable…

Adaptationist Hypothesis

a reason in evolutionary hypotheses for quite some time. The adaptationist program is based on natural selection as an optimizing agent. Adaptation is a trait that an individual carries that helps him or her do well in a particular environment. (Fuentes, 2009). The adaptationist program consist of two steps; everything is treated as a single trait which was optimally considered by natural selection, and if that step fails, recognize that optimization of the whole requires trade-offs and thus some…

Essay on Anth: Evolution and Natural Selection

theories about natural selection has brought confusion to several scientists’ minds, debating whether these theories are true or not. As for Jonathan Weiner, he completely agrees with Darwin. In his article, Evolution in Action, he states how the biological life is quickly changing right in front of our eyes and claims that though there are arguments about whether Darwin’s theories are true or not, there has been evidence of natural selection. Weiner includes several examples of natural selection in his…

Why Natural Selection Is Important In Understanding Human-Environment Relations

most significant would have to be natural selection. Before explaining why that is, understanding what natural selection is will help give a better understanding to its’ significance. Within its’ definition, one can understand why natural selection is so important in understanding the interaction between humans and their surroundings. It can be difficult to understand natural selection without understanding evolution, natural selection is defined as “the process by which species adapt to their environment”…

Charles Darwin's Theory Of Natural Selection

study today. The theory of natural selection is a notion that all life is related and has descended from a common ancestor; from plant life to the animal kingdom. This specific theory states as if all complex creatures evolved and matured over time from simple creatures who adapted with the environment. Said theory suggest beneficial mutations, the dying of weaker fractions of the species; while stronger and more superior fractions live on, but it is a slow gradual process. The basis of the theory…

Evolution: Unifying Theme In Biology

The theory of evolution is a unifying theme in biology. A lot of things in biology revolves around evolution. Evolution is the explanatory framework. There are a lot of evidences that backs up the claim that evolution is a unifying theme in biology. One evidence is fossil. Fossils are a record of life that existed in the past. Fossils can come in several forms ranging from preserved remains to permineralization . Scientists think about the age, location and what the environment was when they are…

Mice Adaptation Lab Report

Mice Adaptation Introduction: The experiment conducted deals with simulating mice adaptation through natural selection. Adaptation is the process by which, as a result of natural selection, organisms become better matched to their environment. One example of an adaptation which many animals have is the ability to camouflage. When an animal is able to camouflage, it is able to blend in with its habitat, making it hard for predators to spot them. Organisms can adapt to their environment through…

Artificial Selection 5. How do humans affect artificial selection? What role does nature play? Darwin stated that nature provides the variation among organisms, and humans select and breed for the variations they find useful or appealing 6. What is another name for artificial selection? Selective breeding 7. Describe how you could use artificial selection to breed pigeons with large beaks. Find pigeons that naturally have larger than normal beaks. Mate these pigeons. Repeat this process over…
