The cover photo for Maxwell Empire Books
The Maxwell Empire is produced by changing distant planets into Earth 2, Earth 3, etc.
To make the change from barren landscapes to lush oases they need the DNA from all the species on Earth to replace that of the less developed cells they replace.
The process starts with algae spores.
The cover photo represents the idea of seeds being necessary to terraform a planets barren surface into a living one. All eight million Earth species will become the planets biosphere, hence the planet is seeded with all Earth life.
