When living things reproduce, they transmit information from one generation to the next. This is in a new combination so that children are not exactly like their parents, although the information itself, which is expressed in the make-up of those children, was there all along in both parents. That is, the deck was reshuffled, but no new cards were added. The technological achievements of humankind in storing information seem sensational. Yet compared to this, the feat of information miniaturization performed by DNA is nothing short of mind-blowing.
Estimates vary widely.
Using simple analogies, based upon the storage space in DNA, they range from 500 large library books of small-type information, to more than 100 complete 30 volume encyclopaedia sets. When you think about it, even that is probably not enough to specify the intricate construction of even the human brain, with its trillions of precise connections. This becomes truly sensational when you consider that there are 75 to 100 trillion cells in the body. It is a thousand times as far as from the earth to the sun. No population can be infinitely old, nor contain infinite information.
