Using one-sided interpretations, evolutionists sometimes present living things as actually constituting intermediate forms. However, the fact that a species has features belonging to another living group does not make it an intermediate form.
For example, the Australian duck-billed platypus is a mammal, but lays eggs, just like reptiles. In addition, it has a beak just like a bird. However, its fur, milk glands and inner ear structure define it as a mammal. Scientists therefore refer to the platypus as a mosaic creature.Such prominent evolutionist paleontologists as Stephen J. Gould and Niles Eldredge admit that mosaic creatures cannot be regarded as intermediate forms.62
