 Around 3000 BC Dragon 's Egg cools enough to allow a stable equivalent of " chemistry " , in which " compounds " are constructed of nuclei bound by the strong force , rather than of Earth 's atoms bound by the electromagnetic force . As the star 's chemical processes are about one million times faster than Earth 's , self @-@ replicating " molecules " appear shortly and life begins on the star . As the star continues to cool , more complex life evolves , until plant @-@ like organisms appear around 1000 BC . One lineage of these later became the first " animals " , the earliest of these stealing seedpods from sessile organisms and some later lineages becoming predators .
