Answer is (C) The birds of Bocas del Toro evolved from immigrants from the mainland.
A scientist studying tropical birds in Panama notices that the environment of the islands of Bocas del Toro is more like the environment of small islands in Honduras than that of the mainland of Panama. She hypothesizes that birds in Bocas del Toro will share more traits with birds on the islands in Honduras than they will with birds on mainland Panama. She records her observations of bird species in all three locations and concludes that the species on Bocas del Toro are more similar to species on the nearby mainland. The similarity in the traits can be because the birds of Bocas del Toro evolved from immigrants from the mainland.
