Cacti in the deserts of southwestern North America and some euphorbs (succulent plants) of the deserts of Africa, have barrel-shaped stems, short-lived leaves, and spines, yet these two types of plants are from different evolutionary lineages. This is an example of A. selective breeding. B. transitional forms. C. homologous traits. D. convergent evolution. E. concave evolution

Answer:D. convergent evolution

Explanation:

Cacti or cactuses are member of the plant family and are often referred to as spiny plants that are usually found in the desserts.

Evolution - In biology, is described the ascent or descent in the characteristics of a species over a series of generations

and natural selection favors its modification.

When two species populations evolve to become more similar to each other we say say they have a convergence evolution.

Hint: Evolution of analogous structures is always an example of convergent evolution.
