microevolution
The term that describes changes within a species over time is "microevolution." This involves genetic variations that occur within a population, leading to changes in traits or characteristics in response to environmental factors.
microevolution
"Microevolution" describes changes that occur within a species over time, affecting traits such as color, size, or behavior. These changes are brought about by factors like natural selection, genetic drift, and mutations.
Evolution of a species can occur as a result of changes in the environment, leading to natural selection of traits that provide a survival advantage. These changes can also be driven by genetic mutations that introduce new variations within a population. Over time, these factors can lead to the adaptation and divergence of the species.
species level. Microevolution refers to small-scale changes in allele frequencies within a population over a short period of time, and this typically occurs within a species. At higher taxonomic levels, such as genus, family, or order, the changes are usually more pronounced and can be considered macroevolution.

Punctuated equilibrium
The term that best describes the result of a new species evolving from an existing species is "speciation." This process occurs when populations of a species become reproductively isolated and undergo genetic changes over time, leading to the emergence of distinct species. Speciation can occur through various mechanisms, including allopatric, sympatric, and parapatric speciation.
