Vestigial organs are those which resemble organs in other species but which are too small to be functionally useful.  Examples include rear legs in some snakes<ref>[http://www.esconi.org/Karen_Komments_PDF/KK6-June2006.pdf Report on fossil snake with lizard-like features and legs]</ref> and whales<ref>[http://www2.ucsc.edu/seymourcenter/PDF/3.%20Whale%20Skeleton%20Activity.pdf Diagram of blue whale skeleton, showing "leg" bones]</ref>, the appendix in humans and wings in flightless birds such as ostriches or kiwi <ref> [http://www.savethekiwi.org.nz/NR/rdonlyres/1BF57624-0105-41DB-BBFD-4BFEC7C2E62C/0/rc12_wing.jpg Photo of kiwi wing stump] </ref>,<ref>[http://www.chem.cmu.edu/groups/Collins/about/kiwi.html Kiwi information page]</ref>.

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.
