If a local population of a species goes extinct, which of the following best describes what has occurred?

• A. The species has adapted to new environmental conditions in that area.
• B. The species has disappeared from that specific area, but may still exist elsewhere.
• C. The entire species has become extinct globally.
• D. The genetic diversity of the species has increased in that area.

Answer: (B)

Verified step by step guidance

1. Understand the concept of local extinction: Local extinction occurs when a species disappears from a specific geographic area but continues to exist in other regions. This is different from global extinction, where the species is completely eradicated worldwide.
2. Analyze the options provided: Evaluate each statement to determine which one aligns with the definition of local extinction. For example, the species adapting to new environmental conditions does not describe extinction, and increased genetic diversity contradicts the loss of a population.
3. Focus on the correct description: The correct answer should emphasize that the species has disappeared from the specific area but may still exist elsewhere, which matches the definition of local extinction.
4. Eliminate incorrect options: Rule out statements that describe global extinction or other unrelated phenomena, such as adaptation or increased genetic diversity.
5. Conclude with the correct understanding: Local extinction is a localized event affecting a population in a specific area, while the species may persist in other regions.
