Lesson 26-1 The past life of the earth
It is animals andplants which lived in or near water whose remains are most likely to bepreserved, for one of the necessary conditions of preservation is quick burial,and it is only in the seas and rivers, and sometimes lakes, where mud and silthave been continuously deposited, that bodies and the like can be rapidly coveredover and preserved. But even in the most favourable circumstances only a smallfraction of the creatures that die are preserved in this way before decay setsin or, even more likely, before scavengers eat them. After all, all livingcreatures live by feeding on something else, whether it be plant or animal,dead or alive, and it is only by chance that such a fate is avoided.
