In evolutionary biology, the concept of trade-offs is crucial in understanding how organisms adapt to their environments. A trade-off occurs when a beneficial trait in one context poses a disadvantage in another. For instance, consider a hypothetical species of birds that have developed larger beaks over generations, possibly due to the availability of larger seeds in their environment. However, larger beaks may hinder their ability to exploit smaller food sources or impede their mating displays. Which of the following evolutionary scenarios best illustrates the concept of trade-offs in this context?
