Fig. 1

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. Filled circles describe landmarked vertebrae
