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:

The second student argues the birds are different species due to different color patterns and mating seasons. Evidence that supports this is the key - differentiating factor mentioned, which is the different mating seasons. Similar body structures and beaks support the first student's argument of them being the same species, and different color variations are not the main evidence the second student uses.

Answer:

The birds have different mating seasons.
