Well, at least those scientists admit past mistakes and get on with it.
It is a side effect of our conscious, and our early training, that we think we are the smartest and most intelligent creature on Earth.
Now we are starting to see that predatory dinosaurs were smart, fast, skilled at hunting. Most predators must be smart, fast, and skilled at hunting or they go extinct.
Sure, we are clever and good at making tools.
But to believe any other life form is not intelligent, or not as 'smart' as a human, is a mistake that can be fatal.
One of the smallest life forms (and therefore possesing the 'smallest brain') appears to be more intelligent than humans, and is always ahead of the game in the battle between us and them.
It is the virus.

No, now some are starting to form hypotheses similar to what you state. It is still all pretty much wild speculation.
What we actually know is that there are none alive today and they were fairly large with sharp pointy teeth, which meant spinach was a problem before dates.
