Book: The evolutionary biology of species

I work on the evolution of species diversity. Why does life evolve into the distinct species? What are mechanisms shape speciation and adaptive divergence? What are the adaptive causes and consequences of species diversity? The work combines theory with experimental, molecular, genomic and field approaches across a range of organisms.
