#2577 - Gregory Forth

Episode of The Joe Rogan Experience · November 5, 2026 · 2 h 19 min

Joe Rogan talks with anthropologist Gregory Forth about Homo floresiensis, Flores islanders' accounts of living small 'ape men,' Bigfoot, and the scientific conservatism around hominin evolution.

Summary

Anthropologist Gregory Forth joined Joe Rogan to discuss Homo floresiensis, the small hominin discovered on the Indonesian island of Flores in 2003 and announced in 2004, and his decades of fieldwork among Flores peoples. Forth described first hearing in 1984 of the Ebu Gogo, creatures the Nage people said their ancestors exterminated centuries ago, and later collecting over 30 encounter reports from the Lio region of creatures called lai ho'a, some recorded shortly before the fossil discovery. He noted the term appears in a 1933 Lio–German dictionary, which he took as evidence the accounts did not derive from the fossil find.

The pair discussed Flores's ecology—pygmy stegodons, Komodo dragons, giant rats and human-introduced animals—the redating of the Liang Bua fossils, the 700,000-year-old Mata Menge remains, and related small hominins such as Homo luzonensis and Homo naledi. Forth recounted the microcephaly controversy, sided with Chris Stringer's suggestion that floresiensis derives from a very primitive lineage, and argued that the discovery supported a 'bushy' rather than linear view of human evolution. He also described a 2019 sighting by two British hikers and plans by a Dutch colleague for a camera-trap and drone search.

Forth stressed that he does not claim the creatures definitely survive, only that some Lio reports may reflect real experiences, and contrasted them with folklore such as the palm civet legend. He said he does not find Bigfoot credible, discussed the 1884 'Jacko' story, the Patterson–Gimlin film, and the reluctance of scientists to voice sympathy publicly. Rogan raised ethical concerns about capturing such a creature, and Forth previewed his forthcoming book on witchcraft beliefs.

Key points

Gregory Forth
Forth says that in 1984 the Nage people told him of small hominoid creatures that had lived in a nearby volcano cave but became extinct two to three hundred years earlier.
“there were a group of these, used to live close by in a cave high up on a nearby volcano. But they had become extinct about two, three hundred years before”
Listen from 1:51 · Ebu Gogo
Gregory Forth
Forth reports that recent analyses suggest stegodons eaten by Homo floresiensis were killed by Komodo dragons, with the hominins scraping meat rather than hunting.
“these stegodons, which may have been consumed by Floresiensis, were killed not by Floresiensis, not hunted by... but instead were killed by Komodo dragons”

Gregory Forth
Forth argues that Flores lacks native apes and monkeys, making misidentification less likely than in Sumatra, since its only macaque was introduced by humans.
“Flores has only one species of monkey and no apes. And the monkey, a macaque, a long-tailed macaque, was introduced by humans thousands”
Listen from 12:55 · Flores
Gregory Forth
Forth says he recorded over 30 encounter reports in Lio, of which about a dozen were much more interesting than the rest.
“I recorded over 30 reports of encounters, some of them not terribly credible. Others, you know, a dozen or so much more interesting”
Listen from 14:01 · Homo floresiensis
Gregory Forth
Forth says that the lai ho'a appear in a Lio–German dictionary published in 1933, indicating the idea of these creatures predated the fossil discovery.
“that was another strong indication that the whole notion of these creatures hadn't come from the fossil discovery”
Listen from 32:37 · Between Ape and Human
Gregory Forth
Forth argues the match between the floresiensis reconstruction and Lio descriptions is too remarkable to dismiss, though coincidence remains possible.
“the match is so remarkable that... You know, and this has been some huge, well-hidden conspiracy designed entirely to fool little old me. I just can't imagine it”
Listen from 43:01 · Homo floresiensis
Gregory Forth
Forth recounts that two British hikers independently contacted him after seeing a bipedal creature on a Flores mountain in March 2019.
“the encounter was in 2019, in March. And, you know, they hadn't followed this. They hadn't thought about it”
Listen from 52:23 · Flores
Gregory Forth
Forth argues that over at least 50,000 years and a 700,000-year possible ancestry, floresiensis must have ranged widely across Flores rather than a single locality.
“the notion that they were restricted to one small neighborhood is just not credible. They must have been all over the map of Florence”
Listen from 1:04:56 · Homo floresiensis
Gregory Forth
Forth says he agrees with Chris Stringer that floresiensis may derive from a far more primitive lineage near the australopithecines.
“he suggested that for his answers, it's something much, much more primitive physically and that it derives from something much older”
Listen from 1:19:29 · Homo floresiensis
Gregory Forth
Forth argues that the discovery of floresiensis supports a bushy family tree of human evolution rather than a single linear progression.
“The view now seems to be that the human tree, family tree, as it were, is bushy”
Listen from 1:20:49 · Human evolution
Gregory Forth
Forth stresses he does not claim floresiensis or a descendant definitely survives, focusing instead on the experiences of Flores people.
“I don't attempt to argue that Floresiensis or something deriving from Floresiensis is definitely still around. I'm not going to make a statement of conviction like that”
Listen from 1:25:30 · Homo floresiensis
Gregory Forth
Forth explains that a fantastic Lio creature said to grow extra testicles yearly turned out to be the palm civet, whose glands can be mistaken for testicles.
“It turns out to be the palm civet. Ah. Which is a well-known animal and with some interpretation, you know, has features that accord with all these exaggerated claims”
Listen from 1:34:54 · Asian palm civet
Joe Rogan
Rogan argues that capturing such a creature would raise serious ethical problems because it is neither quite a monkey nor a person.
“It gets real squirrely if they captured one of these things and then they have to decide what to do with it”
Listen from 1:37:20 · Homo floresiensis
Gregory Forth
Forth says that while discovery would vindicate him, he believes it would be better to leave the creatures alone if they exist.
“It would also kind of vindicate me, I guess you might say. But on the other hand, I think it would be much better if they still exist to leave them alone”
Listen from 1:38:08 · Homo floresiensis
Gregory Forth
Forth says some paleoanthropologists and biologists find his arguments credible privately but won't say so in print, partly over funding concerns.
“I know paleoanthropologists, biologists as well, who find my arguments credible. But it's very interesting, you know, they'll never say so in print”
Listen from 1:52:39 · Bigfoot
Gregory Forth
Forth contrasts Flores villagers, who gain nothing from reporting sightings, with North American Bigfoot claimants who can seek fame.
“nobody on Flores thinks they're going to become famous by telling me what they've seen, whatever it may have been”
Listen from 1:58:10 · Bigfoot
Gregory Forth
Forth states that he does not find Bigfoot credible and has said so in print, considering the Flores accounts far stronger due to fossil evidence.
“No, I don't find Bigfoot credible. And again, I've said so in print in an earlier book”
Listen from 2:05:36 · Bigfoot
Joe Rogan
Rogan says the dense Pacific Northwest forests make it plausible that something could hide there and difficult to find footprints or see anything.
“it's so dense that the trees, the way I describe it, it's like a box of Q-tips. It's insanely dense. You can't see anything”
Listen from 2:07:33 · Bigfoot
Gregory Forth
Forth says his forthcoming book argues that witch beliefs closely resembling Western ones are nearly universal across cultures, though he does not believe in witches.
“there are very few cultures anywhere that don't have a belief that corresponds very closely, even in the smallest particulars, to what we understand by belief”
