Share:
- 1Species with greater body mass evolve slower due to low adaptability.
- 2Longer life cycles reduce the number of generations over time, limiting the frequency of genetic recombination and the accumulation of heritable variations.✓
- 3Short-lived organisms do not require adaptation because environmental pressures on them are minimal.
- 4Rapid reproduction reduces overall genetic variation, which significantly slows down evolutionary change.
Correct answer
Longer life cycles reduce the number of generations over time, limiting the frequency of genetic recombination and the accumulation of heritable variations.
