Figure 10


Fig. 10. Evolutionary steps in [E, L] morphospace. Trajectory of the population mean from generation 1 to 10 (italic numbers). Arrowheads indicate transitions where selection was present; all transitions include change by chance (drift + mutation). The ellipses represent the population's footprint in morphospace (axes ± 1 s.e.m.). Contours represent isoclines for tail stiffness k. Note that selection operates in directions that both increase and decrease k.
