Question

a student argues that two species of birds are the same species because they have similar body structures, similar dna, and similar beaks. another student argues that the birds are different species because they have different color patterns and have a different mating season. which piece of evidence supports the second student’s argument?

the birds have similar body structure.

the birds have similar beaks.

the birds have different color variations.

the birds have different mating seasons.

Explanation:

The second student argues the birds are different species. Similar body structure and beaks (first two options) support the first student's argument of same species. Different color variations (third option) is a weaker indicator of speciation. Different mating seasons (fourth option) is a key reproductive isolation factor, a strong indicator of different species as it prevents interbreeding, directly supporting the second student's claim.

Answer:

D. The birds have different mating seasons.
