Maybe in some fields, we need more “stupid” ideas that don’t depend on what “should have” evolved.

Reset! Different segs of virus genome can exist in different cells but work together
Researchers: It has long been believed that all of the genome segments must move together from cell to cell to cause an infection. But the new study shows this is not the case.
Researcher: Virus sequences in human genome implicated in ALS
The genome isn’t what it used to be.
New paper: Cambrian explosion driven by viruses from space
Delivered by comets. Abstract: We review the salient evidence consistent with or predicted by the Hoyle-Wickramasinghe (H-W) thesis of Cometary (Cosmic) Biology. Much of this physical and biological evidence is multifactorial. One particular focus are the recent studies which date the emergence of the complex retroviruses of vertebrate lines at or just before the Cambrian […]
Bats “steal” genes from ebola-related virus
Which now seem to serve an as-yet-unknown function in the bat. From ScienceDaily: Some 18 million years ago, an ancestor of mouse-eared bats “stole” genetic material from an ancient virus related to Bola. The swiped genetic sequence — a gene called VP35 — has remained largely intact in the bats despite the passage of time, with few […]
Virus expert highlights the conflict over whether viruses are alive
From science writer Suzan Mazur, at Oscillations, interviewing Bogdan Dragnea, who studies the physical structure of viruses via spectrosopy: Suzan Mazur: Do you consider viruses live organisms since viruses can recognize their targets, attach, and infect their hosts—most viruses using a tail spike and needle [see following Parent lab image]—and as you’ve noted, they can […]
Viruses invent their own genes? Then what is left of Darwinism?
From ScienceDaily: In 2013, the discovery of two giant viruses unlike anything seen before blurred the line between the viral and cellular world. Pandoraviruses are as big as bacteria, and contain genomes that are more complex than those found in some eukaryotic organisms (1). Their strange amphora shape and enormous, atypical genome (2) led scientists […]
