Recently, I wrote about the pandoravirus (as in Pandora’s box), virus so big it seems like a cell, but it isn’t, so it is said to hint at a fourth domain of life. Science, AAAS’s mag, has this to say about it in the Abstract:
“Ever-Bigger Viruses Shake Tree of Life” … Most of the pandoravirus genes don’t look like any genes in known databases, suggesting the viruses originated from a totally different primitive cellular lineage than bacteria, archaea, and eukarya. The tree of life may need to be redrawn to account for these new viruses, some researchers say. (You have to pay to read the article.)
Technically a tree museum is an arboretum. Many are quite elaborate, featuring specimens from around the world.
