Here's an extract of the letter that the director wrote to Shaw:
I am enclosing a sketch of an Australopithecine man-ape from Raymond Dart’s “Adventures with the missing link”, without wishing to seem unappreciative of your rugged and handsome countenance, I must observe there appears to be an incredible resemblance.
Robert Shaw in a publicity still for From Russia with love, 1963
I got hold of a copy of the book mentioned by Kubrick and there is only one "sketch" that fits the description:
Australopithecine sketch from R.Dart's "Adventures with the missing link", The Viking Press, 1959; p.232
This apparently puzzling piece of alternative casting could be understood considering that, by then, the role of Moonwatcher was still conceived as a "cameo": indeed, an annex to the contract signed by MGM for 2001 in early 1965 mentioned not only Shaw but also Toshiro Mifune, Albert Finney, Jean-Paul Belmondo, Richard Kiley, Jose Ferrer and even Gary Lockwood (who ultimately played Frank Poole) as tentative Moonwatchers. All these actors shared (with obvious differences) the same degree of
physical strength and atlethicism that an early version of an ape-men
was, supposedly, in need of.
It is unclear if Kubrick actually wanted one of these actors to really play an apeman, or was, more likely, trying to appease MGM's hunger for star names to 'enhance' the status of a sci-fi flick and set it apart from the b-movie reputation that the genre movies enjoyed at that time; on this regard, for example, in 1964 Kubrick was in talks with Paul Newman for the role of the lead astronaut. Besides that, Kubrick obviously admired Shaw as an full-fledged actor beyond his appearance, as he considered him also for his aborted Napoleon movie, that he intended to shoot after 2001.
"Six degrees of separation" trivia: the screenplay of the first Kubrick movie Fear and Desire was written by Howard Sackler, who would later write an early draft of Jaws (1975): it was him who came up with the idea of the “Indianapolis” speech that was unforgettably delivered on screen by Robert Shaw himself, who (he was also a novelist and playwright) reworked and cut down the dialogue that had previously been expanded by John Milius.
Anyway, as we all know, Moonwatcher was eventually played by Dan Richter, who brought along his talent as mime in order to, essentially, create the character from scratch, therefore departing significantly from the "rugged appearance" concept. (I spoke with Dan for my article How did they shoot the leopard scenes?).

Before Richter, even scottish comedian Ronnie Corbett was considered to play the role, apparently because he had played a Gibraltar barbary macaque in war film Operation Snatch, as he recalled speaking on the Graham Norton TV show.

"The theory [behind Operation Snatch] was if there was a sudden drop in the population of barbary apes, the UK would lose control of Gibraltar. So they had soldiers playing barbary apes to make it look like there were loads of apes.” [...] “Kubrick really did ask to see me. He saw me in the Gibraltar (film)." Corbett laughed (source).
The comedian then went through weeks of tests with the 2001 make-up department, headed by Stuart Freeborn, for costume and make-up. "It was a horrible experience," [...] "They put two straws up my nostrils so that I could breathe and then they covered my whole face, including my eyes, with warm plastic." When he was given a pad to communicate with the plastic on his face, he wrote on it: 'Get it off!' [...] After this frightening ordeal I never did get the part in the end, but I can't remember why not, or what happened next. (source)
