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 else can I help you with?
What is a true statement about microevolution and macroevolution?
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.
What is evolution in the smallest scale called?
Microevolution.
What is a 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.
Why do scientist often use study of microevolution?
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.
Do Stable allele frequencies prevent microevolution?
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.
What is a statement about microevolution and macroevolution?
Microevolution can lead to Microevolution
Which statements about microevolution and macroevolution is true?

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.
