Question

Correctly matched pairs are
A. Allopatric species-separated by a distant barrier
B. Darwin finches-unique to Galapagos island
C. Coacervates-aggregates of large complex organic molecules
D. All of the above

Answer 1

Hint: Allopatric species is an example of allopatric speciation in which the same species evolve differently. Darwin went to Galapagos island to study island flora and fauna. Coacervates is a protobiont.

Complete answer: Species that are separated by a physical barrier and develop differently, types species are known as allopatric species and this type of speciation is known as allopatric speciation. In other words, when a population, formerly continuous in range, splits into two or more geographically isolated populations and forms new species, the mode of speciation is called allopatric speciation. This can happen by subdivision of the original population, when a geographical barrier, such as a creeping glacier, a land bridge (e.g., Isthmus of Panama), or ocean or mountain, cuts across a species range. Alternatively, a small number of individuals may colonize a new habitat that is geographically separated from the original range.
Darwin studied the flora and fauna of Galapagos islands, a chain of islands on the West coast of South America. In the Galapagos islands, Darwin found amazing small blackbirds that are different from each other by their shape of beaks and feeding habits.
Small droplets of prebiotic molecules come together and form large molecules called coacervates.
Allopatric species have the same origin but are separated by physical barriers and evolve separately. Darwin finches are a group of birds that present at Galapagos islands. Aggregates of large molecules called prebiotic molecules are called coacervates.
So the correct option is (D).

Note: Darwin finches that formed separate species in the Galapagos Islands and the Australian marsupials that are radiated to form new species are examples of allopatric speciation. Sympatric speciation is the formation of species within a single population without geographical isolation.
