Convergence is a significant evolutionary phenomenon. Arrival at similar morphologies from different starting points indicates a strong role for natural selection in shaping morphological phenotypes. There is no evidence yet of convergence in the developmental mechanisms that underlie the evolution of convergent developmental phenotypes. Here we report the expression domains in sea urchins of two important developmental regulatory genes (Orthodenticle and Runt), and show evidence of molecular… CONTINUE READING
