In two runs of 100 flips of a coin, there will be about 50% matches. Does 
this mean that the two runs are not independent? Likewise, if two theropod 
lineages extend far enough, they will acquire a number of the same bistate 
characters independently (carpals fused into a "semilunate" being one such). 
Does this mean they're related?
