The term is derived from the words "costard" (a now extinct medieval variety of large, ribbed apple) and "monger" (seller), and later came to be used to describe hawkers in general. Some historians have pointed out that a hierarchy existed within the costermonger class and that while costermongers sold from a handcart or animal-drawn cart, mere hawkers carried their wares in a basket. Costermongers met a need for rapid food distribution from the wholesale markets (e.g., in London; Smithfield for meat,
Fruit anatomy in many ways from the original trait. Due to this, it may be assumed that animal dispersal is an efficient form of dispersal, however there has been no evidence that it increases dispersal distances. Therefore, the question remains of what evolutionary mechanism causes such dramatic diversity. It has been found, however, that simple changes within developmental regulatory genes can cause large alterations within the anatomical structure of the fruit. Even without knowing the mechanism involved in the biodiversity of fruit, it is clear that this diversity is important to the continuation of plant populations. In berries and drupes, the pericarp
