Micro evolution is a mechanism that causes changes in the allele frequencies over time. If they to continue over time it may cause speciation or evolution. Compare the various mechanisms of microevolution, including: Mutation Gene flow Genetic drift Sexual selection Natural selection

Step 1
Mutations can be beneficial, harmful, or neutral. Beneficial mutations can increase the frequency of a favorable allele in a population, while harmful mutations can decrease the frequency of an unfavorable allele. Neutral mutations have no effect on the fitness of Show more…

What is the difference between micro and macroevolution? a. Microevolution describes the evolution of small organisms, such as insects, while macroevolution describes the evolution of large organisms, like people and elephants. b. Microevolution describes the evolution of microscopic entities, such as molecules and proteins, while macroevolution describes the evolution of whole organisms. c. Microevolution describes the evolution of organisms in populations, while macroevolution describes the evolution of species over long periods of time. d. Microevolution describes the evolution of organisms over their lifetimes, while macroevolution describes the evolution of organisms over multiple generations.
