The staggering variation in the forms of life on earth is difficult to easily fathom.  “[I]n May 2016, scientists reported that 1 trillion species are estimated to be on Earth currently with only one-thousandth of one percent described”

For just mammals (animals with hair, giving birth to live young, endothermic) there are an estimated 130 billion on the earth. 

All of this diversity is described, chemical by chemical, in the most profoundly concentrated library of information technology we have ever encountered - Deoxyribonucleic acid (DNA).  Five chemicals (adenine, guanine, cytosine, thymine, and uracil for RNA) are combined to create a massive set of instructions across all life that guide the organization of mindless molecular components into information-rich lattices that drive the creation of every living organism.  The human genome is ~3 billion base pairs (~715 MB pure data stored) contained in 46 chromosomes.
