The statement 'Islands are often isolated, minimizing gene flow and maximizing diversification' explains why islands may have unique species on Earth.
<h3>What is isolation?</h3>
Isolation refers to the absence of gene flow between individuals of the same species for extended periods of time.
Isolation due to geographic barriers (e.g., a island) may led to reproductive differentiation and even to speciation.
In conclusion, the statement 'Islands are often isolated, minimizing gene flow and maximizing diversification' explains why islands may have unique species on Earth.
