Natural Selection in Cichlid Fish Species of Lake Victoria

How did natural selection occur in the cichlid fish species of Lake Victoria?

A. Extinction

B. Phylogeny

C. Cladistics

D. Macroevolution

E. Microevolution

Answer:

Natural selection in the cichlid fish species occurred via microevolution.

Natural selection in the cichlid fish species of Lake Victoria occurred via microevolution. Microevolution refers to the small-scale changes in a population's gene pool over time, resulting in genetic variations. In the case of cichlid fish, variations in traits such as coloration, feeding habits, and body shape allowed certain individuals to have a reproductive advantage, leading to their increased survival and passing on of favorable traits to future generations.

Microevolution plays a crucial role in the adaptation and survival of species in changing environments. By accumulating small genetic changes over time, populations can adapt to new ecological niches and challenges, ensuring their long-term survival.

Understanding the mechanisms of natural selection, including microevolution, helps us comprehend the diversity and complexity of life on Earth. It showcases the intricate interplay between genetic variation, environmental factors, and evolutionary processes that shape the natural world.
