Homologous organs have the same fundamental structure but are different in functions are called homologous orangs. These organs follows the same basic plan of organization during development. But in adult condition, these organs are modified to perform different function as an adaptation to the different environment. Homologous organs are the resultant of divergent evolution Bougainvillea or a tendril of Cucurbita, both arising in the axillary position Analogous organs which have similar functions but are different in their details and origin are called analogous organs. The analogous organs shows convergent evolution
