the climate changed‚ the types of plants and animals changed also. Holocene sediments contain remnants of more recent plants and animals‚ so it’s pretty easy to differentiate geologically between these two epics. Now there is growing evidence that the presence of humans has altered the earth so much that a new epic of geologic history has begun – the Anthropocene epic‚ a new human-influenced epic.
