Thus to express the common ancestry of birds and crocodilians, these groups
might be ranked as, say, orders within a subclass of the class Reptilia. Such a

The seeds of plants vary in size and capacity for dormancy; mechanisms of
dispersal over long distances include water, transport in bird guts, or attachment
to the feet, feathers, or fur of birds or mammals. Some freshwater organisms, such
