Lab: Natural Selection-Standard Bio 4.2 — Unit test
Question 10 • Fall 24 GSE Biology B-IC
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?
Answer
A
The birds have similar body structure.
B
The birds have similar beaks.
C
The birds have different color variations.
D
The birds have different mating seasons.
Explanation
Different mating seasons can prevent the birds from reproducing with each other, which supports the idea that they are separate species. Different color patterns may distinguish the birds, but they do not by themselves show reproductive isolation. The best evidence is that they have different mating seasons.
