Fig. 6From: Machine-learning strategies for testing patterns of morphological variation in small samples: sexual dimorphism in gray wolf (Canis lupus) craniaTwo-dimensional feature-space plot of the Israeli C. lupus crania in dorso-ventral view based on the t-distributed stochastic neighbor embedding (t-SNE) algorithm. Note the lack of obvious groupings in the distribution of these coordinate-based representations of morphological variation and sample structureBack to article page
