"We've discovered that the earth isn't flat; that we won't fall off its edges, and our experience as a species has changed as a result. Maybe we'll soon find out that the self isn't "flat" either, and that death is as real and yet as deceptive as the horizon; that we don't fall out of life either."

From the point of view of the species, death is part of this whole process. You could say that species have evolved in such a way that individual members last a certain time. Perhaps a certain kind of species would be better able to survive if the individuals didn't last too long. Other kinds could last longer.
