The correct answer is D. are better adapted to changes.
Variation in a species population provides a buffer against changing environmental conditions, such as shifts in temperature, precipitation, or predator populations. Individuals with different traits may be better suited to survive and reproduce in new conditions, ensuring the population's survival.
This is known as the "insurance hypothesis" or "bet-hedging strategy." By having a range of traits, the population can adapt more effectively to changing environments.
The other options are not the primary advantage of variation in a species population:
A. Dominance of favored traits: While natural selection can lead to the dominance of certain traits, this is not the primary advantage of variation.
B. Easy reach of reproductive age: Variation does not directly impact the age of reproductive maturity.
C. Recognition by mates: Variation can influence mate choice, but this is not the primary advantage.
Additional benefits of variation include:
- Increased fitness
- Enhanced resilience
- Greater genetic diversity
- Improved adaptability
These advantages help populations thrive in dynamic environments.
variation doesn't directly bring about adaptation
it's favourable traits that arise from variation that causes adaptation
so in the absence of that
A is proper

the answer is D
I think the answer should be "are easily recognized by mates"; because variation causes the difference between related organisms(even twins).
