There’s a nice FAQ on Speciation in this week’s Nature -Evolutionary biology: Speciation, by Andrew Hendry. It answers questions such as:
Are species real?
How are species delineated by biologists?
At what point do groups become species?
What is the engine of speciation?
And more. It’s an interesting introduction to how speciation occurs, and indeed what a species is. It also discusses what controversies remain, for example over sympatric speciation. There is a collection of articles celebrating the Darwin anniversary on Nature’s Darwin200 page.
