Meaning
Evolution resulting from small specific genetic changes that can lead to a new subspecies.
Classification
Nouns denoting natural processes.
Examples
- The adaptation of the peppered moth to industrial pollution is a classic example of microevolution in action, where a specific genetic variation led to a shift in population demographics.
- Microevolution has been observed in several species of bacteria that have developed resistance to antibiotics through small genetic mutations.
- In the Galapagos finches, microevolution has led to the formation of distinct subspecies with varying beak shapes and sizes, each adapting to specific food sources.
- Studies have shown that microevolution can occur rapidly in response to environmental pressures, such as the evolution of pesticide-resistant pest populations.
- Microevolution can result in significant changes to a species over time, as seen in the development of London Underground mosquitoes, a distinct subspecies that has adapted to the unique environment of the city's subway tunnels.
