Quote of the Day
"The discrepancy between the histories of populations and the histories of genes within those populations is the biggest problem afflicting the phylogenetics species concepts."
- Coyne, J. A., & H. A. Orr. 2004, Speciation. Sunderland, Sinauer Associates, Inc.
Interestingly, species involve tokogenetic, not phylogenetic relations. Coyne & Orrs perceived problem lies not with history, but with the context in which one chooses to causally account for observations. It also helps to recognize that there is no consensus as to what biologists mean when they use the term 'species,' much less 'taxon.'
