Speciation occurs when a group within a species separates from other members of its species and develops its own unique characteristics. So, the correct option is 'Allopatric species'. ecological equivalents. (c) allopatric. Members of the same species share both external and internal characteristics, which develop from their DNA. The demands of a different environment or the characteristics of the members of the new group will differentiate the new species from their ancestors. (b) sympatric. A community is a group of organisms of different species living together in the same place. (a) sibling.
