Explanation:
The unusual nature of viruses, behaving as living organisms while within them, but becoming in-ert while isolated, has caused scientists to consider the possibility that <u>they are evolving.</u>
The study of life and evolution depends on viruses, particularly the that is causing the current pandemic. Aqueous inside a lipid envelope dotted with chromophores that can absorb solar photons may have given origin to cells.
Incorporating nitrogen into the chemistry of the first cells enabled the creation of amino acids and nucleic acids, which served as a pre-cursor to RNA and later DNA.
Access to the nucleo-protein sediments that have marked the evolution of life and were produced by a goo-gol of metabolically differentiated cells is made possible through metagenomics.
A virus' nucleo-protein particle replicates passively in capable cells. Only the epidemic that a virus causes as a result of spreading from one host to another is used to identify it.
