Morphological diversification of fish as a consequence of the divergence of ontogenetic trajectories]

The possibilities of the investigation of ontogenetic changes in the morphological features of fish using multidimensional "ontogenetic channels," within which individual ontogenetic trajectories run, are demonstrated using African barbs. (Barbus intermedius complex) as an example. The position of ontogenetic channels allows one to judge how the differences of adult individuals in morphological characters arise during development and how their morphological diversity is formed.
