title: Landmark data for copy-cat evolution: Divergence and Convergence within and between cat and dog breeds

description: This dataset contains the three-dimensional measurements of skull
 morphology from physical skulls obtained from natural history collections,
 and CT and micro-CT Scans obtained from veterinary institutions and from
 Morphosource (see Dataset S2 for details on sources) for 1,810 specimens:
 148 domestic cats (Felis catus), 677 domestic dogs (Canis familiaris), 69
 wildcats (Felis silvestris from all recognized subspecies except F.
 silvestris bieti [i.e., F. s. cafra, F. s. libyca, F. s ornata, and F. s.
 silvestris]), 287 wolves (Canis lupus), an additional 185 specimens from
 23 species within Canidae representing 68% of all extant species, an
 additional 350 members of 33 species Felidae representing 85% of all
 extant species, and an additional 94 specimens of 93 species of Carnivora
 representing 93 out of 131 extant genera. These data were obtained from
 museum collections and veterinary schools. Three-dimensional coordinates
 for 47 osteological landmarks (11 median and 36 paired, SI Appendix, Fig.
 S2 and Table S1) were measured on the dorsal and ventral surfaces of
 physical specimens and CT scans. The dorsal and ventral coordinate
 configurations from physical specimens were combined into one set of
 coordinates using a least-squares fit (rotation and translation only) of
 four matching landmarks.
description: # Landmark data for copy-cat evolution: Divergence and Convergence within
 and between cat and dog breeds 3D Landmark data for every specimen in this
 study. The file contains the Id number of the specimen, the genus,
 species, and breed or sub-species, four grouping classifications
 (described below), Sex, Origin, and Location. Following this are the
 centroid size and log centroid size and then the landmark coordinates
 (Symm1, Symm2, etc). Variables: * Id: Identifier for each specimen *

 Cats, Canidae: All members of Canidae except Wolves and Domestic Dogs,
 Carnivora: All Carnivora except Felidae and Canidae, EBDog: Extremely
 Brachycephalic Dog, EBCat: Extremely Brachycephalic Cat, BDog:
 Brachycephalic Dog, BCat: Brachycephalic Cat, DDog: Dolichocephalic Dog,
 DCat: Dolichocephalic Cat, MDog: Mesaticephalic Dog, MCat: Mesaticephalic
 Cat, DFDog: Down-face Dog, Wildcat: Wildcat, Wolf: Wolf. * Group_2:
 Felidae: All members of Felidae except Wildcats and Domestic Cats,
 Canidae: All members of Canidae except Wolves and Domestic Dogs,
 Carnivora: All Carnivora except Felidae and Canidae, DOM_DOG: All Domestic
 Dogs, DOM_CAT: All Domestic Cats, Wildcat: Wildcat, Wolf: Wolf. *
 Group_3: Felidae: All members of Felidae except Domestic Cats, Canidae:
 All members of Canidae Domestic Dogs, Carnivora: All Carnivora except

 Domestic Cats, DOM_DOG: All Domestic Dogs, DOM_CAT: All Domestic Cats. *
 Centroid size: Centroid size for that specimen in cubic centimeters. * Log
 Centroid size: Log Centroid size for that specimen * Symm1, Symm2, and
 Symm3 refer to the x, y, and z coordinates of the first landmark. Symm4,
 Symm5, and Symm6 refer to the x, y, and z coordinates of the second
 landmark. etc.
