Microevolution occurs when there are changes in gene frequency within a population over a short period of time. Microevolution specifically refers to changes within a population, a population being a group of organisms that breed with each other.
Microevolution is the change in allele frequencies that occurs over time within a population.[1] This change is due to four different processes: mutation, selection (natural and artificial), gene flow and genetic drift. This change happens over a relatively short (in evolutionary terms) amount of time compared to the changes termed macroevolution which is where greater differences in the population occur.
As the board continues along the surface, friction in the wheels causes the board to lose energy, which causes the board to slow down and come to a stop.
