Covid is So Small

Compared to an entire cell,viruses are extremely small.  They are the evolution of relics from a time before life became cellular.  Pre-cellular life was all super-tiny.  Things like the mitochondria, the powerhouse of the cell were once free-floating organisms a thousand times smaller than a single cell.  Many of the organelles inside of living cells were independent organisms before cells.  That is one of the most interesting times in evolutionary history.  The first living cells came after millions of years of evolution leading to the parts that would eventually be incorporated into the first living cells.
