if any two individuals can produce VIABLE and FERTILE offspring, then they are of the same species

And that they can do so in any combo. As in, male and female can breed, female and male can breed. Because Neanderthals and humans interbred, but are not the same species...

Are index fossils only used for dating?

Yes, if they use the term 'index fossils' it is referring to dating only, not comparative structure or anything. I asked the same thing.

I never understood how they could interbreed to successively create viable offspring if they're two different species  :-\

Why isn't an abundance of mitochondria indicative of animal tissue? What's the difference between cilia, microvilli and villi?

Is it correct to say that homologous chromosomes have the same telomeres?

The current thinking is that a male Neanderthal is only able to breed with a female human...or you know, maybe the girls of the time just had a thing for the Neanderthals and the boys weren't interested :p

Cilia can move, villi don't (pretty sure that's the difference). Microvilli are just villi on villi.

ahaha! those darn neanderthals :') Thank you :)


I came across a question in the 2003 bio exam 1 concerning year 11 concepts (by memory). Do we need to know this (attached image)?

When the exams ask us, as such found in exam 2 2010, "State a hypothesis to account....." do we have to say "It is hypothesised...."? The answers they provide don't.

For Question 125 (Attached image)

for part b.) I wrote divergent evolution but the correct answer was natural selection.

Can someone please explain to me how this was not in fact divergent evolution but instead natural selection?

Thanks!
