hsc multiple choice on boardofstudies website (1 Viewer)

Are the hsc solutions for the bio multiple choice past papers 100% on the boardofstudies website? I think I caught an error

post question

 

[DepressedPenguino]

It is question 14 in the 2009 bio hsc paper (there is a picture that goes with the question - pic is too large to upload) :/

It's not A or B, don't know how you can even relate it to that question. Clearly not C. So i'm guessing D. Btw where can you check the answers to MC on Board of studies, it's never in sample answers.

Punctuated Equilibrium? What is the answer?

 

[DepressedPenguino]

From the answers that the boardofstudies provided it is D.

It's correct, what did you think it was?

 

[DepressedPenguino]

My answer is B which is divergent evolution because puctauated equilibrium is a theory that suggests a long period of stability, longer than just a few generations, typically millions of years, b4 a short period of rapid changes resulting in the emergence of new species

By same argument you could say it was convergent evolution. There's no way of distinguishing between divergent/convergent here.

Okay, so why do you think the picture supports divergent evolution?
There's no geographical information to support divergent evolution

True tat

I was thinking there couldn't be any totally unrelated species to have the exact same phenotype but the images of the species head is kind da deceiving because phenotype could be hair colour :3 I think D is the answer now

As long as you know why it is right.

It is a model, it's not supposed to adhere to "millions of years", it's just representing punctuated equilibrium by showing several generations of stability and then rapid changes in phenotype. By observing that we can see that the most correct answer is D.
