If you know of recent discoveries that make these statements incorrect, I'm listening.
Well, since all 3 are evolutionary cousins, not ancestors, there is a problem already.
Pilbean is talking about specific lineages of
hominids, not about whether we evolved from gibbons, chimps or gorillas. Such a basic error leads me to suspect some misquotes. Can you give us the entire paragraph, Micaiah. Or didn't the creationist website you are quoting give it to you?
Hmm. a lot of the ones I have are earlier than Pilbean. Appears he wasn't aware of the data that was available even in 1985.
F. Clark Howell, Early Man Time Life Library, 1980
Afarensis to habilis: OH 24 is in between A. afarensis and habilis
Habilis to erectus:
Oldovai: Bed I has Habilis at bottom, then fossils with perfect mixture of characteristics of habilis and erectus, and erectus at top. At bottom of Bed II (top of Bed I) have fossils resemble H. erectus but brain case smaller than later H. erectus that lies immediately above them. pg 81
OH 13, 14 was classified by some anthropologists as H. habilis but others as early H. erectus. 650 cc
Koobi Fora: Another succession with several habilis up to 2 Mya, then transitionals, and then erectus at 1.5 Mya.
Erectus to sapiens: Omo valley. Omo-2 "remarkable mixture of Homo erectus and Homo sapiens characteristics" pg. 70.
Omo-1: another mix of erectus and sapiens
Skhul and Jebel Qafza caves: "robust" H. sapiens at 120 Kya that have brow ridges like erectus but brain case like sapiens.
Tautavel, 200Kya: large brow ridges and small cranium but rest of face looks like H. sapiens.
"We shall see the problem of drawing up a dividing line between Homo erectus and Homo sapiens is not easy." pg 65.
Ngaloba Beds of Laetoli, 120 Kya: ~1200 cc and suite of archaic (erectus) features.
Guamde in Turkana Basin, 180 Kya: more modern features than Ngaloba but in-between erectus and sapiens.
Skhul, Israel "posed a puzzle to paleoanthropologists, appearing to be almost but not quite modern humans"
Erectus to neandertalis:
Stenheim and Swanscombe, 250 Kya: called H. heidelbergensis but have characteristics of both erectus and neandertalis. Large brows and small cranium ( ~1200cc) but otherwise looks like neandertalis
Petroloma skull (complete): brow ridges and low forehead like erectus but not quite as primitive but not as derived as sapiens or neandertalis. Back of head resembles sapiens. 250 Kya
Vertesszollos, 400 Kya. Teeth like H. erectus but occipital bone like H. sapiens. brain ~ 1300 cc
Francis M Clapham, Our Human Ancestors, 1976
Omo Valley, Ethiopia: ~ 500,000 ya. mixture erectus and sapiens features
Sale in Morrocco: skull discovered in 1971, ~300,000 ya. also shows erectus and sapiens features.
Broken Hill skull: another skull with mixtures of erectus and sapiens features
Ehrendorf in Germany and Saccopestore in Italy: mixture erectus and early neandertals, classed as archaic H. sapiens or H. heidelbergensis.
