Vesitigial organs are claimed to be strong evidence in favor of evolution - ostriches, for instance, would be claimed to have evolved from a flying ancestor which no longer needed to fly, and so in subsequent generations the wings shrunk until they were no longer capable of flight, thus helping the bird survive by requiring less food and energy.

Creationists usually claim that vestigial organs aren't really useless at all - for instance, in ostriches the wings might be used for balance or sexual display.  However, it is hard to extend this explanation to internal leg bones in right whales, or the near-invisible wings of the kiwi.<ref> [http://www.savethekiwi.org.nz/NR/rdonlyres/1BF57624-0105-41DB-BBFD-4BFEC7C2E62C/0/rc12_wing.jpg Photo of kiwi wing stump] </ref>
