1 Corinthians 15:37-39

37 The seed you sow is not the body (the plant) which it is going to become, but it is a bare seed, perhaps of wheat or some other grain.

38 But God gives it a body just as He planned, and to each kind of seed a body of its own [is given].

39 All flesh is not the same. There is one kind for humans, another for animals, another for birds, and another for fish.
