Question

Darwin's fishes provide evidence of evolution from
A. Anatomy
B. Morphology
C. Biogeography
D. All the above

Answer 1

Hint: Darwin finches ate a group of about 18 birds of species passerine birds. They are well known for their special characters in beak form and function.

Complete Answer:
Throughout the five year journey, Darwin encountered many new organisms in widely contradictory environments but he had at hand an wide-ranging library of reference books, chiefly the fine known works of French specialists like Cuvier and Lamarck. The bulk of his notes are dedicated to geology and marine invertebrates, his real passions, but the notes he made about his encounters with fish are distinguished by their skilful and correct observations and their vivid descriptions of particular behaviour.

Biogeography is the study of the giving out of species and ecosystems in geographic space and through geological time. Organisms and biological communities frequently vary in a regular fashion along geographic gradients of latitude, elevation, isolation and habitat area. Phytogeography is the branch of biogeography that studies the allocation of plants. Zoogeography is the branch that studies the distribution of animals. Mycogeography is the branch that studies distribution of fungi, which include mushrooms.

Information of spatial dissimilarity in the numbers and types of organisms is as very important to us today as it was to the early human ancestors, as we get used to heterogeneous but geographically predictable environments. Biogeography is an integrative field of examination that unites concepts and information from ecology, evolutionary biology, taxonomy, geology, physical geography, palaeontology, and climatology.

Contemporary biogeographic research combines information and ideas from many fields, from the physiological and ecological constraints on organismal spreading to geological and climatological phenomena that operate at the global spatial scales and evolutionary time frames.

On his way to the Galapagos Islands Charles Darwin found only some types of finches that fluctuated from island to island, which helped him to build up his hypothesis of usual choice. They in addition explored developmental changes in Darwin's finches.

Therefore the correct answer for this question is option C) Biogeography.

Note: Darwin observed that the shape of the beak varies between finch species. And this helped him in solidifying the idea of natural selection.
