Resumo: | Vargas et al. agree with us that a lateral shift in theropod dinosaur digits occurred prior to the origin of birds, but contend that it occurred as a single &amp;#x201c;frameshift&amp;#x201d; with little outward change to the three main digits involved^1^.  We consider the digital morphology of Limusaurus, other ceratosaurs, and non-avian tetanurans to provide evidence that the shift was stepwise, and that a stepwise shift better explains theropod manual morphology than a hidden frameshift.
