As such, the absence of a grooming claw is generally considered an anthropoid synapomorphy.

متن کاملDevelopmental bias in the evolution of phalanges.
Evolutionary theory has long argued that the entrenched rules of development constrain the range of variations in a given form, but few empirical examples are known. Here we provide evidence for a very deeply conserved skeletal module constraining the morphology of the phalanges within a digit. We measured the sizes of phalanges within populations of two bird species and found that successive p...
