Quoted: Just this year, researchers spotted pores in the double-membrane-bound viral factories of coronaviruses, which are eerily reminiscent of the pores found in cell nuclei. “If this result holds up, and assuming that the pore-forming protein was not derived from a eukaryotic genome, then it does blunt one argument against the virus model,” wrote David A. Baum, an evolutionary biologist at the University of Wisconsin, Madison, in an email.
