homogeneous (adj.)

1640s, from Medieval Latin homogeneus, from Greek homogenes "of the same kind," from homos "same" (see homo- (1)) + genos "kind, gender, race, stock" (from PIE root *gene- "give birth, beget," with derivatives referring to procreation and familial and tribal groups). Earlier in this sense was homogeneal (c. 1600). Related: Homogeneously; homogeneousness.
