"On the origin of species: from Darwin to the 21st century"
Although Darwin described the origin of species as “that mystery of mysteries,” modern evolutionary biologists are making substantial progress in understanding how new species arise. I discuss the nature of species and argue that the central question that demands our attention is how barriers to gene exchange arise between diverging lineages. Using case histories of recently diverged taxa, I examine the nature of such barriers and consider how modern genetic and genomic approaches can provide insights into the speciation process.
