Question

Determine whether the following statements about sympatric speciation are true or false. a. Sympatric speciation only occurs in areas where there is local variation in environmental resources. b. A dam dividing a fish population could lead to sympatric speciation.

Answer 1

Answer:

The true statement is - Sympatric speciation only occurs in areas where there is local variation in environmental resources

Explanation:

• Sympatric speciation means the evolution of new species from an ancestor species which are occupying in the same area and no geographical barrier takes place.
• Overlapping of ranges takes place to the organism and old and new        species are living i the same geographical region.
• A dam diving a fish population could lead to allopatric speciation where geographical barrier causes formation of new species which are completely different from their ancestor species.
