'Sentient' can divide a wider class of growing bodies into animals and non-animals. It does not then divide animals into sentient and non-sentient animals: in this classical account all animals are sentient.
Inheritance of a constitutive feature down a hierarchy does not imply repeated subdivision by that same feature at every subordinate level.
