analogous variation Those features with similar functions which have developed independently in unrelated taxonomic groups, in response to a similar way of life. For example, phyllodes (flattened petioles performing leaf functions) which are found on Acacia species are analagous to leaves. Compare HOMOLOGOUS and CONVERGENT EVOLUTION.

analogous variation The occurrence of features with similar functions which have developed independently in unrelated taxonomic groups, in response to a similar way of life, or a similar method of locomotion, or a similar food source, etc. Thus the wings of birds and insects are analogous and phyllodes (flattened petioles performing leaf functions) found on Acacia species are analagous to leaves. Compare convergent evolution.
