Not a good sign in a scientific paper.
A more interesting result is that intelligence on Earth has evolved at least three times - mammals, corvids [1], and octopuses.[2] Those all evolved intelligence after branching off in evolutionary history. And they all have different "hardware" for intelligence.
That's significant. All the mammals have roughly the same brain architecture, with the major components present but in different sizes. Corvids have a different architecture, which is a relatively recent and surprising result.[1] Octopuses are even more different. Yet all three have good vision and manipulation systems, and can learn.
So we now really know that there's more than one way to do it. Once complex life emerges, intelligence probably follows. In the Drake equation, that's fᵢ, the fraction of life bearing planets on which intelligent life emerges. Now that we've seen intelligence evolve three times on our planet, we can be reasonably confident that fᵢ is reasonably large, not close to 0.
Our planet only seems to have one evolutionary form of life. Not sure what that tells us. Is it an unlikely event? Or did our kind of life chemistry eat or crowd out the competition? This paper addresses the issue but is not close to resolving it. Unlike the intelligence issue, which is now settled.
