pollen and larvae

Endless mutations resulting from the constant sex happening all around us. Pollen and larvae, cracked eggs and delivered placentas. Life is constantly experimenting; trying out minutely tweaked DNA to see if this, one, maybe, just might be the one.
A cocklebur gets stuck in the foot feathers of a Sand Hill crane and finds itself on the the Asian side of the bearing straight. The desert to the arctic. A new try at life, a miniature invasion, hoping ancient memories will help it grow in this new land. Seeds explorers carried over continents on feathered starships.
