These changes help the organism survive or reproduce better, or to adapt to its environment. have used genetics, a new science, to explain how evolution happens. They also utilized the physical science to determine how much energy is required to create such changes. Natural Selection In order for evolution to occur organisms must be able reproduce and pass their genes on to future generations. This is known as natural selection, sometimes described as "survival of the most fittest." However the phrase "fittest" could be misleading as it implies that only the strongest or fastest organisms survive and reproduce. In fact, the best adaptable organisms are those that are the most able to adapt to the conditions in which they live. The environment can change rapidly and if a population is not well adapted, it will be unable survive, resulting in an increasing population or becoming extinct. The most fundamental component of evolution is natural selection. This occurs when advantageous traits are more prevalent over time in a population, leading to the evolution new species. This process is driven primarily by heritable genetic variations in organisms, which is a result of mutations and sexual reproduction. Selective agents can be any element in the environment that favors or dissuades certain traits. These forces could be physical, such as temperature or biological, like predators. As time passes populations exposed to different agents are able to evolve differently that no longer breed and are regarded as separate species. Natural selection is a basic concept however it isn't always easy to grasp. The misconceptions regarding the process are prevalent even among scientists and educators. Studies have revealed that students' levels of understanding of evolution are only weakly related t
