Humanity is fast approaching the point where we can edit our genes or otherwise select for intelligence. Even the idea of creating non-human super intelligent agents of some sort is arguably within reach over the course of the next few hundred years.
I like to think that though the starting average intelligence for a given species might be lower than others, eventually we all wind up at the same place, either turning ourselves into or building some hypothetically (given the laws of the universe) maximally intelligent system.

Give a dude in 1000 a voltmeter and things get crazy.
There are people who would disagree with this.

(the genetic selection process is mentioned in the book, the wiki abstract puts more focus on a cultural development)
It's a bit like if you were saying that you couldn't teach a prehistoric child to read (but even more exaggerated) ?
Whilst we don’t understand the correlation between genetics and intelligence on a sufficient level there aren’t that many genetic differences in fact you can’t necessarily distinguish the age of the sample that easily either unless you are looking at very specific groups.
And as far as modern hunter gatherers go we know that they aren’t less intelligent than urban humans.
We have sufficient evidence of advanced tool making and culture spanning back far enough through human history to indicate that intelligence isn't a modern fluke, heck copper mining and smelting dates back to at least 9000 BCE, the pyramids in Giza date back to 2600 BCE which means that we are closer to Caesar to today than Caesar was to the pyramids.
While I’m open to discussion that over 350-400K years some evolutionary steps happened as far as our intelligence goes. But I am more than comfortable with stating that plucking a human from 10K BCE and exposing them to modern education would yield an average human today.
I think many people confuse specializaiton, focus and/or intellect with autism.
Anyway, I didn't want to suggest that everyone had to have it :
Eh? That’s a really weird way of looking at intelligence.
By all accounts of you pluck baby from 10,000 BCE and raise it today it wouldn’t be any different than an average person today.
Now one can argue that aliens might be much more physiologically intelligent than humans on a biological level but that’s not necessarily a given or a requirement.
“Sufficiently advanced technology is indistinguishable from magic” is true but it doesn’t mean that you can’t understand if it’s explained to you.
An alien civilization that simply has a time lead on humanity might be much more advanced but it doesn’t mean that we won’t be able to understand the physics of how they got here once we learn about it.
An ant is severely limited by biology, for the most part it can not really learn or understand things on an abstract level. Humans on the other hand very much can, if aliens can travel faster than light by exploiting some new physics we just need access to their Wikipedia.
