:-) We can be remarkably specific IMO, see my book (academische uitg. Eburon 2022 Utrecht NL): “De Evolutie van de Mens - waarom wij rechtop lopen en kunnen spreken”.

Plate Tectonics apparently split the Catarrhini (= narrow-nosed anthropoids of the Old World = Eurasia + Africa) into Hominoidea (apes+human) & Cercopithecoidea (Old World monkeys) some 30 mill.yrs ago (c 30 Ma), IMO:
1) Pan (chimp+bonobo) & Homo split c 5 Ma, perhaps c 5.3 Ma, when the Red Sea opened into the Gulf:
* Homo followed the S.Asian coasts -> Pleistocene H.erectus c 2 Ma Java, google “verhaegen human evolution”,
* Pan followed the E.Afr.coastal forests & later the opening of southern side of E.Afr.Rift -> Australopithecus africanus->robustus in S.Africa.

2) Gorilla & Homo-Pan split c 8 Ma, IMO in the Red Sea, when Gorilla followed the opening of the northern side of the E.Afr.Rift -> Praeanthropus afarensis->boisei, in parallel with Australopithecus later in S-Africa (late-Pliocene afarensis//africanus->early-Pleist.boisei//robustus resp.).

3) Hominids (Gorilla+Homo-Pan) & pongids (Pongo orangutan) split c 15 Ma, IMO when the Mesopotamian Seaway Closure split the Tethys Sea into the Med.Sea (hominids-dryopiths West) & the Ind.Ocean (pongids-sivapiths East).

4) Greater (hominids-pongids West) & lesser apes (hylobatids gibbon-siamang East) split c 20 Ma, when India went further underneath Eurasia (fm of Himalaya) and the Miocene apes initially followed the S-Eurasian coastal forests (and from the coasts repeatedly inland along rivers/swamp/lakes).

5) Hominoidea (apes) & Cercopithecoidea (catarrhine monkeys) split c 30 Ma, IMO when the earliest apes reached the island archipels then between India & S.Eurasia, where they became bipedal (!) waders-climbers in coastal forests, google “aquarboreal”.

All this may sound unexpected to old-fashioned afrocentric savanna believers, but the facts are obvious IMO, as described in my last book, and google “human evolution verhaegen”.
