Hello all,

I have a request. As the exam approaches, it is becoming really difficult to get over my exam nerves and concentrate on the revision. So I would like to revise with everyone who is interested. I am thinking of deciding a particular time at which everyone who is interested could come online together and we could discuss whatever we need to know for each specification point on the Edexcel GCE Biology Specification. We did this last year on TSR and it helped a lot - I achieved almost full ums so it really did help a lot. In this way, whoever needs to ask doubts could be replied to immediately. Whoever is interested, please state a suitable time (in GMT) until tonight and we can decide a particular time (in GMT ofcourse) which suits everyone.

This is for anyone who wants to find out what their local time is in GMT: http://wwp.greenwichmeantime.com/gmt-converter/

Good Luck all and I really hope we all achieve to the best of our capabilities. Thanks for reading my post.

Who can answer this question :

Using suitable examples, explain how sympatric speciation differs from allopatric speciation (6marks)

• Allopatric speciation occurs between geographically isolated populations. The gene pool of the species' is physically seperated, so the seperate populations can then evolve independently of each other.
• Sympatric speciation occurs when organisms inhabiting the same area become seperated into two or more reproductively isolated groups.

I don't know what else I could write. But check the markscheme.
