Species or Lineages within Species

Mention species concept nowadays and you are likely throw up their hands and give a negative or dismissive reaction. Nevertheless we have another go in our recent paper which appeared this week in the Biological Journal of Linnean Society. Our framework addresses two cornerstone issues in systematics that are often not discussed explicitly in genomic species discovery: diagnosability and how to determine it, and what criteria should be used to decide whether diagnosable lineages are conspecific or represent different species.


  • Reptile genomics and evolution
  • Sex determination in reptiles
  • Phylogenomics and phylogeography
  • Chelonian ecology, evolution, systematics
  • Applications of NextGen sequencing
