The nervous systems in various species do not change rapidly in evolution. Yet the idea that human gait would be controlled in much the same way as it is in other mammals, or indeed even in invertebrates (Clarac et al., 2000
) has met a lot of resistance (Capaday, 2001
). Nevertheless, as evidenced by Dietz et al. in this issue of Brain (Dietz et al., 2002
), we should take this evolutionary idea seriously.
From the work on cats it is known that the rhythmic muscle activities during gait are generated by specialized neural circuits located in the spinal cord (the so-called
