In 1949<ref>{{hnb|Dewar, Davies and Haldane|1949|p=90}}, quoted in {{hnb|Sarfati|2001}} </ref>, J.B.S. Haldane proposed that evolution could be falsified if "various mechanisms, such as the wheel and magnet, which would be useless till fairly perfect" were found in nature.  Creationists typically respond by pointing out that wheels and magnets have been found in nature.  Of course, because all possible evolutionary explanations for their development have not been ruled out, evolutionists will not consider this a falsification, demonstrating that proposed falsification tests can be easily rejected once they fail.

Another proposed test has been dubbed instances of "[[irreducible complexity]]."  Essentially, since evolution requires a step-wise development in which each variation is advantageous enough to survival to spread throughout the gene pool, then evolution with respect to a particular biological structure could be falsified if the components of that organ were found to be totally useless unless already put together.  Creationists and Intelligent Design advocates have proposed a number of such structures, including the eye, the cilia of cells, the enzymes involved in human blood clotting, etc.  Proponents of evolution have responded by describing hypothetical paths for the evolution of each disputed structure that account for useful function at each stage of development.  While it remains unproven that these paths are the actual method by which these structures evolved, they are claimed to serve to disprove the proposition that it is impossible for them to have evolved. Yet they fail to do this because they fail to demonstrate that the hypothetical paths are actually feasible.<ref>Sarfati, Jonathan, [http://creationontheweb.com/content/view/1855 Review of ''Climbing Mount Improbable''], ''Journal of Creation'' 12(1):29-34, April 1998.</ref>

Another test proposed by Haldane was that the discovery of rabbits in [[Precambrian]] strata would disprove evolution.<ref>Ridley, M (2003). Evolution, Third Edition. Blackwell Publishing Limited.</ref>
