Pick up the one not true about the finches collected by Darwin on the Galapagos:

Correct answer: A. Although quite different seemed to be of same species

  • A. Although quite different seemed to be of same species
  • B. Although quite similar, seemed to be of different species
  • C. Separated from original habitats by geographical barriers
  • D. Some were unique to individual islands

Explanation

Most of the animal species on the Galapagos live nowhere else in the world, although they resemble species living on the South American mainland. It was as though the islands were colonized by plants and animals that strayed from the South American mainland and then diversified on the different islands. Among the birds Darwin collected on the Galapagos were 13 types of inches that, although quite similar, seemed to be different species. Some were unique to individual islands, while other species were distributed on two or more islands that were close together.Some were unique to individual islands, while other species were distributed on two or more islands that were close together. A particularly puzzling case of geographical distribution was the fauna of the Galapagos islands. Most of the animal species on the Galapagos live nowhere else in the world, although they resemble species living on the South American mainland.

About Evolution

Evolution describes heritable change in populations over generations through variation, natural selection and adaptation. Lamarckism explains inheritance of acquired characteristics, while Darwinism explains selection of favourable inherited variations; these historical explanations must not be confused with the modern genetic account of evolutionary change.
