Answer:

Convergent evolution

Explanation:

The convergent evolution is a very interesting evolutionary process that is also very helpful when ti comes to explaining how the evolution actually works. This type of evolution appears when two or more different species, be it plants or animals, live in places that are isolated from one another, but have the same or very similar living conditions. The species then evolve in a very similar manner despite them not being closely related at all, bu the response from them is the same in order to survive in the environments that provide the same conditions. If the conditions are very harsh, hot, and dry, thus a desert, then the two plants will develop the same or very similar features. They will have very hard leaves that stop the loss of water. The amount of leaves will be very low. The root systems will be disproportionately large. They will both have the ability to extract humidity from the air. The chances are also very high that they will both have thorns for protection, as well as certain amount of poison in them for the same purpose.
