Two bird species, G. fuliginosa and G. fortis, found on the Galapagos Islands have similar beak morphologies. Yet the birds live together sharing the food resources. Based on the information provided in the graph, identify the type of relationship between the two species and explain why they cooperatively share food resources.

•there must be variation for the particular trait within a population.

•the variation must be inheritable (that is, it must be capable of being passed on from the parents to their offspring).

•individuals with one version of the trait must produce more offspring than those with a different version of the trait.good
