Berry (botany) in fruit type may have led to the evolution of fruit eating in mammals and birds. Fruit type has been considered to be a useful character in classification and in understanding the phylogeny of plants. The evolution of fruits with a berry-like pericarp has been studied in a wide range of flowering plant families. Repeated transitions between fleshy and dry pericarps have been demonstrated regularly. One well-studied family is the Solanaceae, because of the commercial importance of fruit such as tomatoes, bell peppers, and eggplants or aubergines. Capsules, which are dry dehiscent fruits, appear to be the original form of
Marrow (vegetable) processed for food when required. They are a popular vegetable in Great Britain and areas with significant British influence, though their popularity is waning in favor of immature summer squash like courgette. Giant marrows are grown competitively in the United Kingdom where the term "marrow" is often restricted to the striped, thick-skinned cultivar. In a culinary context, marrows are treated as a vegetable; usually cooked and presented as a savory dish or accompaniment. Botanically, marrows are fruit, a type of botanical berry, being the swollen ovary of the marrow flower. Marrows, like all squash, have their ancestry in the Americas.
