Scientists call these synonymous parts homologous structures. Some structures exist in organisms that have no apparent function at all, and appear to be residual parts from a past common ancestor.

WebHumans, whales, lizards, and birds all have differently shaped forelimbs, reflecting their different lifestyles.
