NLN PAX RN/PN Science - General Exam Info Sample Questions

Define Evolution.

Correct Answer:
changes in a population's genetic composition over time.


evolution refers to the process through which species undergo changes over time due to genetic variations and environmental factors. at its core, evolution is the change in the genetic composition of populations over successive generations. this change is driven by several mechanisms, including natural selection, mutation, gene flow, and genetic drift, which influence the reproductive and survival success of individuals within a population.

the concept of evolution is rooted in the idea of descent from a common ancestor. this fundamental principle posits that all species, living and extinct, are descended from ancient common ancestors. over time, through the process of branching and divergence, these lineages evolve into new species. the fossil record, along with genetic data, provides substantial evidence supporting the theory of common descent, showcasing how complex life forms have evolved from simpler ancestors over millions of years.

natural selection plays a pivotal role in the process of evolution. it occurs when certain traits become more common in a population because they confer some advantage that increases the likelihood of survival and reproduction. these traits are often heritable, passed from parents to offspring. in any given environment, factors such as predation, climate, and competition for resources can create selective pressures that influence which traits are advantageous. over time, natural selection can lead to significant changes in the population’s characteristics, sometimes even leading to the emergence of new species—a process known as speciation.

another aspect of evolution is genetic drift, a mechanism that involves random changes in the gene frequencies of a population. unlike natural selection, which is non-random and driven by environmental pressures, genetic drift occurs by chance. it is particularly significant in small populations and can lead to drastic changes in gene frequencies purely by accident, sometimes leading to the loss of genetic variation within the population.

mutation is another crucial component of evolution. mutations are random changes in the dna sequence of an organism, which can create new genes or alter the function of existing ones. while most mutations are neutral or harmful, some can confer benefits that may be favored by natural selection. over generations, these mutations can accumulate, leading to significant evolutionary changes.

gene flow, or the movement of genes between populations, also contributes to evolution by introducing new genetic material into a population. this can increase genetic diversity and affect how a population adapts to its environment. when populations of the same species are separated by physical barriers (like mountains or rivers), they may evolve independently through mutation, natural selection, and genetic drift, potentially leading to speciation.

in summary, evolution is a complex process influenced by multiple factors that alter the genetic makeup and traits of populations over time. understanding evolution is crucial for insights into biodiversity, the adaptation of species to changing environments, and the ongoing processes that shape life on earth.
