Fig. 1From: Morphological modularity in the vertebral column of Felidae (Mammalia, Carnivora)Illustration of the five hypotheses of intervertebral phenotypic modularity tested here. Black rectangles illustrate sets of vertebrae which are hypothesized to show high integration among themselves and, therefore, to represent a module. See text for detailed description of hypotheses. Hypothesis 1: Traditional regions. Hypothesis 2: Cervicothoracic and lumbar modules. Hypothesis 3: Thoracolumbar module. Hypothesis 4: Anticlinality model composed of vertebrae T10, T11 and T12. Hypothesis 5: Developmental model disruption. C, T, and L stand for cervicals (blue outline), thoracics (red outline), and lumbars (green outline), respectively.
