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, citing different color patterns and mating seasons. Among the options, we need evidence that directly supports this claim. Different mating seasons mean the two groups cannot interbreed, a key criterion for defining distinct biological species, making this strong supporting evidence. Different color variations are cited but are a weaker species-defining trait compared to reproductive isolation from differing mating seasons.

Answer:

D. The birds have different mating seasons.
