Data from: Issues and perspectives in species delimitation using phenotypic data: Atlantean evolution in Darwin's finches

Carlos Daniel Cadena, Felipe Zapata & Iván Jiménez
Progress in the development and use of methods for species delimitation employing phenotypic data lags behind conceptual and practical advances in molecular genetic approaches. The basic evolutionary model underlying the use of phenotypic data to delimit species assumes random mating and quantitative polygenic traits, so that phenotypic distributions within a species should be approximately normal for individuals of the same sex and age. Accordingly, two or more distinct normal distributions of phenotypic traits suggest the...
