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.

What is a true statement about microevolution and macroevolution?
Microevolution can lead to Microevolution
Can microevolution form a new species?
Yes. In fact, microevolution, or allelic variance, is the mechanism by which new species emerge. Such an emergence is part of what some people call macroevolution. In other words, microevolution is the mechanism by which macroevolution is produced.
Do Stable allele frequencies prevent microevolution?
no
The only taxonomic category in which microevolution can occur is the?
species
When microevolution occurs what kind of frequencies change?
allele
What is A mutation that causes resistance in a population of beetles is an example of?
Microevolution
What is a statement about microevolution and macroevolution?
Microevolution can lead to Microevolution
What is a true statement about microevolution and macroevolution?
Microevolution can lead to Microevolution
Which statements about microevolution and macroevolution is true?
microevolution can lead to macroevolution
What is the process of microevolution?
notion
What is the role of population genetics in the study of microevolution?
Microevolution can be studied by observing changes in the numbers and types of alleles, or genetics, in populations.
Can microevolution form a new species?
Yes. In fact, microevolution, or allelic variance, is the mechanism by which new species emerge. Such an emergence is part of what some people call macroevolution. In other words, microevolution is the mechanism by which macroevolution is produced.
