Which characteristic is shared by humans and r-selected species?

• A. Long lifespan
• B. High parental investment
• C. High reproductive rate
• D. Ability to adapt quickly to changing environments

Answer: (D)

Verified step by step guidance

1. Understand the concept of r-selected species: These species are characterized by high reproductive rates, producing many offspring with relatively low parental investment. They often thrive in unstable or unpredictable environments.
2. Consider the characteristics of humans: Humans typically have a long lifespan, high parental investment, and a lower reproductive rate compared to r-selected species.
3. Identify the shared characteristic: While humans do not share the high reproductive rate or low parental investment of r-selected species, they do have the ability to adapt quickly to changing environments.
4. Analyze the adaptability: Both humans and r-selected species can adapt to environmental changes, although the mechanisms may differ. Humans use cultural and technological adaptations, while r-selected species rely on rapid reproduction and genetic variation.
5. Conclude the shared trait: The ability to adapt quickly to changing environments is a characteristic that can be shared by both humans and r-selected species, despite their other differences.
