“The lower red line at CS = 18 nm marks the threshold between unheated fish (CS < 18 nm) and fish heated at moderate temperatures (200–500 °C).”
This suggests the use of an oven type of arrangement (obviously stone), an even more significant development than what the bs bbc article suggests (passage is from the paper itself).
AH-HAH: Found it
“Identification of the cooking method practiced by the GBY inhabitants is indeed a challenge, especially since no traces of cooking apparatus have been preserved at the site, nor at any other Acheulian site. Nonetheless, ethnographic and experimental studies indicate that fish cooking requires production of low–moderate heat (300–500 °C), while preventing fast cooling or direct burning44,49,70–72. One possibility, therefore, is that the GBY inhabitants used some kind of earth oven that maintained a temperature below 500 °C (refs. 73–75) to cook their fish.”
It’s amazing that the bbc couldn’t highlight the TRUE nature of this discovery (not).
IMHO, this lends more evidence for lost culture. 780k years ago. Just wow.
I agree. There’s evidence in some other (less old) sites that soup was made, but it was a preceramic culture, so, apparently they built a sort of tripod and hung a skin full of ingredients over an open fire. Or somethin’.
