Explain why the north American cactus and African euphoria species have evolved such similar adaptations.

The North American Cactus and African Euphorbia species originated from two different, but similar plants.

Explanation:

These plants were the typical herbaceous species of the early Earth, characterised by their slim stems and large, wide leaves. However, their evolutionary paths began to change with the separation of the early supercontinents, Pangaea and Gondwana. As variations in the climate caused the development of harsh, arid, desert environments, both plant families experienced convergent evolution in order to adapt and survive. Cacti and Euphorbias both converged on similar forms and metabolisms after prolonged exposure to corresponding environments, due to the fact that similar biomes can require the same adaptations.

Hope u will understand this

yes you are doing it right great gob
