Many of the fruits we enjoy today are transplants, brought here by immigrants from Belgium, France, England, Spain and other countries. John Chapman preached the Gospel throughout Indiana and Ohio in the early 1800's and planted apple seeds as he went. The Spanish were the first to plant the olive tree in California. A leaf from the hardy olive tree was the first sign given Noah that plant life had returned to the Flood ravaged earth. A bird brought that sign of life to Noah.
Birds are also responsible for the wide dispersion of seeds.
Birds eat the fleshy fruit of plants, and then scatter the seeds, either by rejecting them before eating them, or dispersing them through their digestive tract. Allspice plantations in Jamaica have been expanded greatly simply because the bird population feeds on the fruit and then drops the seeds in the surrounding areas. This name has been given the plant because just a slight brush of the hand can cause the tiny football shaped seed pod to split into five parts that roll up tightly. This action can shoot the seeds contained in the pod several feet. Another plant that shoots its seeds out is the wild geranium.
