How it can change in response to its enviroment
Explain. I have never seen the term selection used.

The structure of DNA allows for genetic variation through mutations, which introduce new traits into a population. Natural selection acts on these variations, favoring traits that increase an organism's fitness for its environment. Over time, these advantageous traits can accumulate in a population, leading to species adaptations and evolution.
The ammount of food would increase because the aphids also eat garden plants.
Today scientists explain natural selection as the process by which organisms with advantageous traits for their environment are more likely to survive, reproduce, and pass on those traits to their offspring. Over time, this leads to changes in the genetic makeup of a population as a result of the gradual accumulation of beneficial adaptations.
The breeder's equation explains how genetic variation influences the selection of desirable traits in breeding programs. It states that the response to selection for a particular trait is determined by the genetic variation for that trait and the strength of selection pressure applied. In breeding programs, breeders aim to increase the frequency of genes associated with desirable traits by selecting individuals with those traits to be parents of the next generation. This process helps to improve the overall genetic quality of the population over time.
The branch of psychology that studies the ways in which natural selection and adaptation can explain behavior and mental processes is evolutionary psychology. This field explores how behaviors that may have evolved to increase our ancestors' chances of survival and reproduction continue to influence our thoughts and actions today.
Natural selection was important because it provided a mechanism to explain how evolution occurs. It operates by allowing individuals with advantageous traits to survive and reproduce, leading to the gradual accumulation of those traits in a population over time. This process helps to explain the diversity of life on Earth and how organisms have adapted to their environments.
Early RNA molecules may have varied in their ability to catalyze reactions or replicate themselves, leading to differences in survival and reproduction. Those RNA molecules with beneficial traits would have had a selective advantage, allowing them to increase in frequency within the population over time through natural selection.
When a population increases, there is greater potential for influences such as disease to have a greater impact on the population. The total numbers of people affected will be greater than in a smaller population.
