Two organisms occupying a particular geographical area (say desert) show similar adaptive strategies. Taking examples describe the phenomenon.
Organisms found in the same geographical area often have similar adaptations, and this is called convergent evolution. It is commonly observed in desert plants, although not all of them are closely related.
Cereus Peruvianus a cactus species primarily found in the South America and Euphorbia Virosa show similar adaptations such as fleshy succulent stem, deeper roots, and absence of leaves to conserve water. Modified fleshy succulent greenish stem participate in photosynthesis, as leaves are modified into spines to reduce water loss through transpiration. These are examples of analogous organs which manifest convergent evolution.
