Question #72b15
1 Answer
The changes in the organism are determined by the competition within the species (infraspecific0 and by competition and interactions with other species ( interspecific.)
Explanation:
The Beak of The Finch gives great examples of this kind of evolution within a species creating new species or sub species of finches.
On the Islands when the weather is dry. The species of birds with a larger beak have an advantage over birds with a smaller beak and the beaks of the large species form of finch. The larger beck allows the large beak species to eat seeds that other birds can't eat. When the weather is wetter this advantage disappears . Intra speciation.
In wetter years the Hydrid form of the Finch has an advantage and the population of Hybrids soars. The large beck species of the finch breeds with the medium species of the finch. This allow the hybrid to each both large seeds and medium seeds.
Because the Galapagos Island had few birds when the Finches arrived on the Island the birds adapted to
