The same as the causes of so called macroevolution. The change in allele frequency over time in a population of organisms. By mutation, natural selection, genetic drift and gene flow.
I would rip to pieces about half of the Biology text books of America over this constant misunderstanding of evolutionary theory they perpetrate.
The main causes of microevolution are genetic mutations, gene flow, genetic drift, and natural selection. Genetic mutations introduce new genetic variation, gene flow brings in genetic variation from other populations, genetic drift causes random changes in allele frequencies, and natural selection favors certain traits that increase an organism's fitness in a given environment.
Microevolution refers to small-scale changes in gene frequencies within a population over generations, while macroevolution involves large-scale evolutionary changes that lead to the formation of new species. Both processes are driven by genetic variation, natural selection, and other evolutionary mechanisms. Microevolution is the basis for macroevolution, as accumulated small changes can eventually result in the divergence of distinct species.
Microevolution.
Microevolution refers to small-scale changes in allele frequencies within a population over a short period of time. These changes can include factors such as genetic drift, mutations, natural selection, and gene flow within a population. Microevolution is responsible for the variation we see within species.
Scientists often study microevolution because it allows them to observe changes in gene frequencies within a population over a short period of time, providing insights into mechanisms of evolution. By studying microevolution, scientists can better understand how genetic variation leads to adaptations that shape the diversity of life forms.
No, stable allele frequencies do not prevent microevolution. Microevolution involves changes in allele frequencies within a population over time, even if those frequencies are stable for a period. Evolution can still occur through mechanisms such as genetic drift, selection, and gene flow, even if allele frequencies are temporarily stable.

notion
Microevolution can be studied by observing changes in the numbers and types of alleles, or genetics, in populations.
