There is a lot to be discovered, but it’s almost like some scientists are looking at the problem from the wrong angle, certainly in the short-term.

If an alien were to look at a sheet of sandpaper, they might learn very little about what it does, but to see that sheet being used explains the apparently chaotic arrangement of sand particles glued to the surface.

Maybe the perceived chaos of the quantum realm is a by-product of actions being performed elsewhere?

For example, the current theory for gravity is that the vast majority ‘leeks’ into higher dimensions.

Could it be that we are the [un]happy recipient of forces emerging from somewhere else?

Agreed. Nature tries to re-use its code, so to speak. But similarities can only take you so far. Phenomena that arise out of Quantum Mechanics do not have any large scale similarities. On the other hand, fractal patterns can be found in crystal growth, which suggests a scale-independent growth pattern!

In its natural environment, given that people wore so few clothes, the disease could spread rapidly and easily.

Once the disease had been taken from its natural habitat, into colder climes and where people worse much more clothing, the disease had to improve its skill set and infection vectors.

However, evolution really isn’t the point that I’m making. In this scenario, evolution is merely an agent of change.

I’m more interested in the similarities across scales of size and proportion…

Think of the plague in the Middle Ages. It so rapidly killed off many of its victims, that it had little chance to propagate. So, as a result, despite killing millions, the plague itself died out.

The infectious diseases that survive today, have been plaguing humanity for thousands of years. The more virulent strain must have destroyed tribes, and destroyed themselves in the process. The least virulent ones also died out, as they could not infect very many people. Only the intermediate ones survived.
