when there can be lifetimes between the a troll’s death and the hatching of their descendant, it might also be called into question just how much room for evolution there even is in the Alternian reproductive system. the incestuousness of the Alternian gene pool isn’t lateral, but backwards; the genetic material of each new generation of trolls is constantly being folded back into the genes of the trolls who were alive centuries ago. the very concept of “Ancestors” in the Alternian culture exists because Alternian children are separated from their progenitors by such a vast gulf of time; but on Beforus trolls raised each other from youth, so did they have any use for the idea? after the scratch, Dirk and Roxy were flung far into the future to ensure they never met their forebears; it was by the Condesce’s decree that humans would be born “long after the original donors had died” so that “no one would ever be able to know who their "parents” were, or be able to trace their lineage“. so could the same thing have been done on Alternia, the reproductive process tweaked so that trolls would take centuries longer to be hatched, another way of minimising any potential connection or intimacy between Alternians?
