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 students 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:

According to the biological species concept, organisms that are able to interbreed and produce fertile offspring are considered the same species. If two groups of organisms have different mating seasons, they cannot interbreed. So, different mating seasons is a key piece of evidence for different species. Similar body structure, similar beaks, and different color variations do not prevent inter - breeding (which is the key in species definition).

Answer:

The birds have different mating seasons.
