The scientific evidence for this assertion is based on the Duck codicil to Occam's Razor. As you know, Occam holds that when presented with differing explanations for a phenomenon, the simplest explanation is the most likely to be true.
The Duck Codicil, antecedents unknown, holds that if an outcome has three or more consistencies with an hypothesis for its cause, then it is likely that the hypothesis is correct. The Codicil is useful especially where experimentation is not possible.
More colloquially, 'If it swims like a duck, quacks like a duck, eats like a duck and shits like a duck, then it is a duck.'
