Question

A new plant species is introduced to daphne major and produces small, thin seeds. this plant species is highly adapted to drought and after 5 years has replaced over 80% of the native plants that produce large seeds. how will this change affect the evolution of beak size in the medium ground finch population?

Answer 1

This change did not affect the evolution of beak size in the medium ground finch population because small beaks will be favored under rainfall conditions.
The medium ground finch has a beak that look likes stubby and eats generally seeds. The thing that Medium ground finches a decent subject for an investigation of evolution is that they are variable in size and shape.
