Glenn is describing a different paper than JTEM was. I take it
that Ron O is quoting from the paper that Glenn is referencing.

I have no idea why Gould wrote the above, and don't have the time
to chase it down to find out whether Gould had a useful description
of what he meant by "anything like human intelligence."
What I can say is this. If the tape of life were to be rerun to the
Maastrichtian, the epoch immediately preceding the great
extinction that ended the Mesozoic Era and ushered in the Cenozoic Era,
there were some dinosaurs (especially troodonts)
that could well have evolved to produce
"something like human intelligence."
Given the same millions of years that produced us, of course, and assuming
they survived the catastrophe the way many other "dinosaurs" did. [I am
referring of course to the "consensus" that birds are dinosaurs. The troodonts
were actually quite closely related to them.]
What might mammals have produced in the same time period, if not us?
Competition from these earthbound close relatives of birds might have stifled
the line that produced us. However, if those troodonts had taken another 50
million years to produce something on our level, and the island of Madagascar
had continued to be isolated from the continents, then IT might have evolved
a species on our level of intelligence earlier than the troodonts.
The surviving species of lemurs give no hint as to the amazing primates
that this island produced. I say "surviving" because Homo Sapiens hunted
the six biggest and most amazing ones to extinction in -- get this -- the last thousand
years or so. That's how long it is estimated that humans have lived on Madagascar,
according to one widely believed estimate.
Had this not happened, our zoos might have been greatly enriched by primates at least
as disparate as all the ones that are alive today. One was on the level of intelligence,
it is estimated, of baboons. What might that one genus, *Archaelemur,* have
produced in another 50 million years?
Nor is that the only possibility. In another 50 million years, if we humans make ourselves
extinct some time before we make them extinct, raccoons or (horrors!) rats might evolve
to produce another species with what Gould might have called "like human intelligence”.

As usual, Ron O beats around the reality bush without giving anyone
anything that looks like specifics. I hope I haven't gone to the opposite
extreme in this post, in the minds of readers.

PS This post is very much in the spirit of the OP of a thread I began a few
hours ago:
WHY I KEEP POSTING TO TALK.ORIGINS
https://groups.google.com/g/talk.origins/c/UyETkw4gf78/m/-2GdOwEBBwAJ
I have posted on the ideas I've written about above before, but the
stimulus provided by the Gould quote has enabled me to organize my
thoughts as never before.
