Figure 2.

Palate length and cranial volume of Felis cat species. Domestic cats are represented by orange dots, F. catus × F. silvestris hybrids by olive squares, F. lybica by purple diamonds and F. silvestris by blue triangles. (a) Palate length of all four groups in mm over basal skull length in mm (our data). (b) Cranial volume in cm³ of all four groups over basal skull length in mm (our data). (c) Cranial volume data of F. catus and F. silvestris cats in cm³ over the total skull length from [2]. (d) Cube root of cranial volume data for all four groups in cm from [1]. (e) Cube root of cranial volume data for F. catus, F. lybica and F. silvestris cats in cm from [1].
