A scientist argues that two species of birds are the same species because they have similar body structure, similar DNA, and sim
ilar beaks because they eat the same food. The birds do have some variations in color patterns and have a different mating season. Which piece of evidence would go against this argument and suggest that the birds are actually different species? The birds have similar body structure. The birds have similar beaks. The birds have different color variations. The birds have different mating seasons.
-Different species of birds have different mating or breeding seasons. Evolution has played a role in adjusting the timing of avian(birds) breeding seasons to maximize the number of young produced. The breeding season depends on a number of factors, for example In the temperate, subarctic, and arctic zones, the overriding factor is the availability of food. This varies across all different species of birds, irrespective of other similarities they may have.
The birds have different mating seasons would answer the question whether the two bird species are actually the same species or just two different ones. The reason for this is that when two bird species have different mating seasons this actually tells us that they most likely don't mate with each other and for that reason it wouldn't be really possible for them to be one species.
The answer is C) selective breeding. This means that humans are deciding what to breed which means this is not a natural selection, but rather an artificial selection.
