why do desert plants have thorns instead of leaves ?Explain the answer according to theories of Charles Darwin and Jean Baptiste de Lamarck

Answers



Charles Darwin's theory of natural selection postulates that plants with thorns are more likely to survive in dry, arid desert environments than plants without thorns, as thorns may provide the plant with protection from predators and the elements. According to Jean-Baptiste de Lamarck's theory of evolution, plants in dry, arid climates would change due to their need for protection and thrive more successfully if they had thorns. This would cause them to produce offspring with thorns, as the thorns would give them a survival advantage over other plants without thorns, leading to the proliferation of thorny plants in desert regions.
