Mechanism Of Natural Selection
Following a sudden environmental disaster, a population of hamsters experienced differential survival, where individuals with naturally larger wings survived and those with smaller wings perished. Which of the following best explains why larger wings became more prevalent in subsequent generations?
Environmental pressures directly induced the growth of larger wings in each individual, increasing the prevalence of the trait in the population.
The hamsters intentionally modified their wing size to adapt to the disaster, and these modifications were subsequently inherited.
The hamsters developed larger wings during their lifetimes in response to environmental conditions and passed this acquired trait to their offspring.
Individuals with naturally larger wings survived and reproduced at higher rates, thereby increasing the frequency of this trait in the population.
