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
Forbidden fruit Although commonly confused with a seed, in the study of botany a wheat berry is technically a simple fruit known as a caryopsis, which has the same structure as an apple. Just as an apple is a fleshy fruit that contains seeds, a grain is a dry fruit that absorbs water and contains a seed. The confusion comes from the fact that the fruit of a grass happens to have a form similar to some seeds. A fresco in the 13th-century Plaincourault Abbey in France depicts Adam and Eve in the Garden of Eden, flanking a Tree of Knowledge that
