No Viruses
We all know how many problems viruses can cause, but did you know that they can actually have a number of benefits? Even some bigger viruses can get viruses themselves, known as virophages! They’re an important part of keeping life balanced on our planet, and we couldn’t survive without them.

However, the jury is still out on whether or not viruses should be considered living things, as they pass some of the tests but fail others. We don’t even know how they evolved in the first place! Perhaps in the future, we’ll learn more about these microscopic monsters and how they managed to come about.
