“you can see the population of rice at archaeological sites, it starts off mostly as brittle, meaning it shatters easily, and over time it takes about 1,500 yea…”

Dibble states archaeological rice populations show a shift from brittle to non-shattering forms taking about 1,500 years to reach full domestication.

“For example, here are this publication by Canuto in 2018 records 61,480 structures still to be excavated, found with LIDAR and surface survey, right? And so at…”

Dibble cites a 2018 publication by Canuto reporting 61,480 Maya structures identified via LIDAR and surface survey in northern Guatemala.

“And so the thing is at this point, we have something like three million shipwrecks from around the world. And so one of my questions for Graham is, if this is …”

Dibble states there are roughly three million shipwrecks recorded around the world, none attributable to a lost Ice Age global civilization.

“and when you go down and you take up soil samples associated with that stonework you find that they date back to about 25,000 years ago. None of those cores ca…”

Dibble states that none of the radiocarbon-dated soil cores used to claim a ~25,000-year-old Gunung Padang structure actually came from the described tunnels or chambers.

“Oh, the oldest seeds we have go back tens of thousands of years. The oldest domesticated crops we have go back about 11,000 years. And where are those from? Fr…”

Dibble states the oldest domesticated crops date to about 11,000 years ago, from the Fertile Crescent region of Syria and Turkey.

“We have evidence against it from those pollen cores, but also this article by Peter Richardson and colleagues points out that agriculture, it was probably too …”

Dibble cites Peter Richerson and colleagues that Ice Age agriculture was likely impossible because atmospheric CO2 was too low for intensive plant growth.

“And I'd say we could definitively prove there was no large-scale metallurgy in the Ice Age. If you look at ice cores in the Arctic, right, we can track metallu…”

Dibble claims Arctic ice cores record lead emissions from Roman and medieval metallurgy but show no metallurgical emissions during the Ice Age, ruling out a large-scale metal-working civilization then.
