Context: <response>: ```Judging relationships based on shared characters dey require carefulness, because plants fit resemble each other through convergent evolution wey characters don come up independently. Some euphorbias get leafless, rounded bodies wey dem adapt for water conservation wey resemble those of globular cacti, but characters like the structure of their flowers dey make am clear say the two groups no dey closely related. The cladistic method dey use systematic approach for characters, wey dey separate those wey no get information about shared evolutionary history - like those wey evolve separately for different groups (homoplasies) or those wey remain from ancestors (plesiomorphies) - and derived characters, wey don pass down from innovations for a shared ancestor (apomorphies). Only derived characters, like the spine-producing areoles of cacti, dey provide evidence for descent from a common ancestor. The results of cladistic analyses dey show as cladograms: tree-like diagrams wey show the pattern of evolutionary branching and descent.```
