Alright all you biological scientists out there
I remember, years ago, reading about some birds, in the arctic or somewhere in the north, I think, whose range kept extending around the lake, with little changes each time, until they finally came full-circle and the new birds couldn't breed with - and therefore were a different species to - the old ones, even though there was a continuous line all the way back. This would be a perfect example of parapatric speciation for an assignment I'm doing, but I can't remember what the birds were or where they were or anything. Anyone else heard of this, or anything like it?

Re: Alright all you biological scientists out there
You made the deep inside of my brains itch, because i know what you mean, but I can't think of the right species right now .
Anyway, I did find this: http://www.orientalia.org/wisdom/Phi.../Species.shtml
Maybe to get started?
See if I can dig up my studies books and find the answer...

Re: Alright all you biological scientists out there
Well, I figured out that I'm trying to find ring species. Now to work out whether they're an example of parapatric speciation or not...
edit: Wikipedia says yes. Hurrah! Problem solved!Last edited by Serpentine; 2007-09-03 at 07:30 AM.

Re: Alright all you biological scientists out there
Hah. My science teacher showed us a video almost exactly like the OP last year. Pretty much talked about how its hard to distinguish between species because one Group A can breed with group B, but not with Group C, and Group B and breed with both. Its a pity I can't remember the name of the species.
