Fitness is a result of which of the following factors?
A. Overproduction
B. Adaptation
C. Variability
D. Homology
I think it is B
I agree.
You're on the right track! Fitness, in the context of biology and evolution, refers to an organism's ability to survive and reproduce in its environment. It is influenced by various factors, including adaptation.
Adaptation plays a significant role in determining an organism's fitness. An adaptation is a trait or characteristic that enhances an organism's chances of survival and reproduction in its particular environment. Organisms with beneficial adaptations are more likely to survive and pass on their genes to the next generation, increasing the overall fitness of the population.
However, the options A, C, and D may not directly relate to fitness. Let's evaluate them individually:
A. Overproduction: Overproduction refers to the tendency of organisms to produce more offspring than can possibly survive. While overproduction affects population dynamics, the concept itself does not determine an individual organism's fitness.
C. Variability: Variability refers to the diversity of traits within a population. While variability can influence the potential for adaptation, it is not a direct factor in determining fitness.
D. Homology: Homology refers to similarities in traits or characteristics between different species due to common ancestry. While it may have implications for evolutionary relationships, it is not directly linked to an organism's fitness.
Therefore, the correct answer is B. Adaptation contributes significantly to an organism's fitness by allowing it to better survive and reproduce in its environment.
