Guest guest Posted December 25, 2009 Report Share Posted December 25, 2009 >If plants wanted to be eaten, then why would they evolve defences I already pointed this out. Most plants have evolved specific parts to be eaten by animals, as part of their reproductive systems. They often defend other parts, such as the leaves that produce their nutrition via photosynthesis -- but the grasses and grains use their leaves much as other plants use their flowers, fruits, and tubers. More sophisticated plants grow flowers or fruit that can only be consumed by certain species who are particularly likely to distribute their seeds in a favorable manner. This has reached extremes in the various adaptations of certain South American flowering trees to attract specific species of hummingbirds, whose bills are tapered or curved to suit just that flower. Evolution to attract partial consumption by animals is a characteristic ubiquitous among plants, and unique to plants. No animal has undergone a comparable evolutionary process -- although humans have imposed adaptations to enhance edibility on various livestock species, these convey no inherent advantage to the animal, whereas being eaten by the right animal is essential to the propagation of most plants. -- Merritt Clifton Editor, ANIMAL PEOPLE P.O.
