How does the study of island biogeography explain the presence of distinct species on isolated islands?

A. It indicates that islands have fewer environmental niches for species to occupy.
B. It demonstrates that islands are devoid of any indigenous life forms.
C. It highlights the role of isolation and adaptation in generating new species.
D. It proves that islands are not conducive to the survival of diverse species.

Answer :

Final answer:

Island biogeography explains the presence of distinct species on isolated islands through the concepts of isolation and adaptation. These factors allow species to evolve independently, leading to unique traits and diversity. The theory emphasizes how geographic isolation can result in significant evolutionary changes and the emergence of endemic species.


Explanation:

Understanding Island Biogeography

The study of island biogeography provides important insights into how distinct species can thrive on isolated islands. This theory, developed by ecologists Robert MacArthur and Edward O. Wilson, emphasizes the significance of isolation and adaptation as key factors in generating new species.

Key Concepts in Island Biogeography

  • Isolation: When an island is isolated, its species become separated from those on the mainland. This leads to limited gene flow, allowing populations to diverge and evolve independently.
  • Adaptation: In response to unique environmental pressures, species on islands may evolve specific traits that enable them to survive and thrive in their particular habitats. For instance, the finches of the Galápagos Islands showcase how variations in beak size and shape are adaptations to the different types of available food.
  • Niche Availability: Islands often provide a variety of ecological niches, even though they might be fewer in number than on a continent. This encourages species diversification and the development of endemic species.

Ultimately, the principles of island biogeography highlight how geographic isolation can lead to profound evolutionary changes, resulting in distinct species that are specially adapted to their island environments.
