|
Mutations help an organism to better survive in their environment
|
|
|
An organism may acquire a helpful mutation by interacting with the environment
|
|
|
A mutation may result in an adaptive trait that makes an organism more likely to survive and reproduce
|
|
|
Organisms with certain traits are more likely to win competitions for mutations
|
Detailed explanation-1: -In natural selection, genetic mutations that are beneficial to an individual’s survival are passed on through reproduction. This results in a new generation of organisms that are more likely to survive to reproduce.
Detailed explanation-2: -Mutation is the engine of evolution in that it generates the genetic variation on which the evolutionary process depends. To understand the evolutionary process we must therefore characterize the rates and patterns of mutation.
Detailed explanation-3: -Which statement below best describes the role of mutations in evolution by natural selection? Mutations increase the genetic variation within a population, and some of the variants may provide an advantage to individuals over time.
Detailed explanation-4: -Mutations are one of the fundamental forces of evolution because they fuel the variability in populations and thus enable evolutionary change.
