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
With its exceedingly specialized structures, the platypus also refutes this claim. (See Platypus, The.)
