PBS: "Where Did Viruses Come From?"

Where Did Viruses Come From?” from PBS Digital and PBS Eons.

Most of us have viral DNA, even templated by retroviral RNA, in our genomes.

The video examines whether viruses came before cellular life, and it isn’t clear.

And because viruses don’t produce energy, there is a good question as to whether they are really alive. An RNA or DNA strand wrapped in protein. The video examines some very large viruses, actually larger than some bacteria.
