Models do not explain how these would have formed if the big bang occurred the way it was proposed.
Answer:
1. Iterative homology: e.g. antenna and leg of fiddler crab
2. Ontogenetic homology: e.g. radular teeth of veliger, feathers of chicken and hen
3. Di-polymorphic homology: e.g. white and brown feathers of hen races, chelae of male and female of fiddler crabs
4. Supraspecific: e.g. chelae of fiddler crab, chelae of lobster, feathers of hen and pheasant
