00:15:23,089 more about what animals were being eaten. 293 00:15:24,691 --> 00:15:27,826 EMRA: So, in terms of the number of bones on the site 294 00:15:27,827 --> 00:15:32,332 {\an8}we've probably looked at... over 100,000. 295 00:15:33,967 --> 00:15:36,770 NARRATOR: Many of the fragments are poorly preserved. 296 00:15:37,904 --> 00:15:40,706 And the first challenge is identifying which bones 297 00:15:40,707 --> 00:15:43,008 came from which species. 298 00:15:43,009 --> 00:15:46,412 I've seen a lot of gazelle, so, 299 00:15:46,413 --> 00:15:47,780 these little vertebra, 300 00:15:47,781 --> 00:15:50,883 gazelle ribs-- some of the larger 301 00:15:50,884 --> 00:15:53,285 stuff are from cattle, so the aurochs. 302 00:15:53,286 --> 00:15:56,389 We found boar, sheep. 303 00:15:57,924 --> 00:16:01,460 NARRATOR: While gazelle make up more than half of the identified bones, 304 00:16:01,461 --> 00:16:05,397 the presence of what seem like familiar farm animals, 305 00:16:05,398 --> 00:16:08,534 such as cattle and sheep, raises 306 00:16:08,535 --> 00:16:11,637 the possibility that the people of Göbekli Tepe 307 00:16:11,638 --> 00:16:13,740 were farming their food. 308 00:16:14,841 --> 00:16:17,409 Stephanie's research is trying to distinguish 309 00:16:17,410 --> 00:16:19,144 whether these bones are from 310 00:16:19,145 --> 00:16:22,849 domesticated herds or their still-wild ancestors. 311 00:16:24,784 --> 00:16:27,386 EMRA: In a controlled herding environment, 312 00:16:27,387 --> 00:16:30,356 you would have more adult females and young males 313 00:16:30,357 --> 00:16:31,557 being killed off 314 00:16:31,558 --> 00:16:33,025 and this is not something that we see. 315 00:16:33,026 --> 00:16:34,827 We would also see a 316 00:16:34,828 --> 00:16:36,895 shift in the size of the animals, 317 00:16:36,896 --> 00:16:39,298 so domestic animals tend to be a bit smaller 318 00:16:39,299 --> 00:16:40,834 than their wild counterparts. 319 00:16:42,635 --> 00:16:44,937 NARRATOR: Early farm animals were mostly smaller 320 00:16:44,938 --> 00:16:48,006 than their wild relatives, due to poorer nutrition 321 00:16:48,007 --> 00:16:50,209 and being penned into enclosures 322 00:16:50,210 --> 00:16:52,212 rather than running free. 323 00:16:53,646 --> 00:16:55,781 I have these examples. 324 00:16:55,782 --> 00:16:57,483 {\an8}This one is from Göbekli. 325 00:16:57,484 --> 00:17:01,120 {\an8}And this one is from a medieval site in Germany. 326 00:17:01,121 --> 00:17:03,857 {\an8}And you can see the massive size difference. 327 00:17:05,759 --> 00:17:07,192 {\an8}You can never really say from just 328 00:17:07,193 --> 00:17:10,562 one bone, whether it's going to be a wild population 329 00:17:10,563 --> 00:17:12,164 or domestic population, 330 00:17:12,165 --> 00:17:14,566 but having thousands of bone fragments, 331 00:17:14,567 --> 00:17:17,737 you can then get an idea of the, sort of, size of the animals. 332 00:17:20,140 --> 00:17:23,842 NARRATOR: The animal bones found at Göbekli Tepe suggest the animals 333 00:17:23,843 --> 00:17:26,044 eaten here were wild. 334 00:17:26,045 --> 00:17:28,280 (fire crackling) 335 00:17:28,281 --> 00:17:30,950 The people here didn't keep livestock... 336 00:17:32,318 --> 00:17:34,687 ...but slaughtered wild animals. 337 00:17:37,323 --> 00:17:40,025 In addition to the heavier

us to reconstruct both the diet 349 00:18:12,091 --> 00:18:15,261 and the landscape around the settlement. 350 00:18:16,396 --> 00:18:19,832 NARRATOR: The smallest fragments, charred by ancient fires, 351 00:18:19,833 --> 00:18:23,635 hold clues to what the people who came here ate. 352 00:18:23,636 --> 00:18:26,138 ANTOLÍN: We are looking for charred seeds 353 00:18:26,139 --> 00:18:29,074 and charred pieces of wood, because these are the only 354 00:18:29,075 --> 00:18:31,543 organic plant material 355 00:18:31,544 --> 00:18:35,782 that preserves in dry sites. 356 00:18:36,883 --> 00:18:39,952 NARRATOR: Among the microscopic, blackened plant remains, 357 00:18:39,953 --> 00:18:42,321 Ferran finds more fragments of one plant 358 00:18:42,322 --> 00:18:44,389 than any other. 359

00:18:54,266 it was probably intensively harvested 363 00:18:54,267 --> 00:18:56,035 by people living at the site. 364 00:18:57,103 --> 00:19:00,839 Since we started the new analysis in 2023, 365 00:19:00,840 --> 00:19:04,710 we've been able to see that einkorn is the 366 00:19:04,711 --> 00:19:08,314 most frequent plant that we are identifying. 367 00:19:10,283 --> 00:19:14,153 NARRATOR: Einkorn was one of the world's first domesticated grains. 368 00:19:15,955 --> 00:19:19,491 But Ferran's research is revealing something surprising 369 00:19:19,492 --> 00:19:22,028 about the einkorn eaten at Göbekli Tepe. 370 00:19:23,096 --> 00:19:26,865 ANTOLÍN: Wild plants disperse their seeds on their own. 371 00:19:26,866 --> 00:19:28,634 That's the goal; that their seeds 372 00:19:28,635

00:19:39,045 It's called shattering ear. 376 00:19:40,313 --> 00:19:44,516 NARRATOR: This shattering ear allows seeds to spread naturally. 377 00:19:44,517 --> 00:19:49,121 But domesticated, farmed einkorn is different. 378 00:19:49,122 --> 00:19:53,158 ANTOLÍN: This is the ear of domesticated einkorn. 379 00:19:53,159 --> 00:19:56,495 And all of the spikelets are still attached 380 00:19:56,496

Ferran is finding at Göbekli Tepe 386 00:20:15,848 --> 00:20:19,052 are all from ears with shattering rachis. 387 00:20:20,119 --> 00:20:23,255 This is wild einkorn. 388 00:20:23,256 --> 00:20:26,758 ANTOLÍN: The fact that we have wild einkorn at Göbekli Tepe 389 00:20:26,759 --> 00:20:29,061 is indicating that people 390 00:20:29,062 --> 00:20:32,030 were not yet cultivating the plant, 391 00:20:32,031 --> 00:20:35,168 but they were harvesting intensively. 392 00:20:36,703 --> 00:20:39,071 NARRATOR: Until archaeologists find clear markers 393 00:20:39,072 --> 00:20:42,841 of early crop cultivation, like the presence of certain weeds 394 00:20:42,842 --> 00:20:47,245 that thrive in tilled soil, the evidence suggests 395 00:20:47,246 --> 00:20:52,085 the einkorn was gathered from the wild, not planted fields. 396 00:20:54,520 --> 00:20:57,155 When coupled with the wild animal bone evidence, 397 00:20:57,156 --> 00:20:59,791 it points to the people at Göbekli Tepe 398 00:20:59,792 --> 00:21:02,127 being hunter-gatherers, 399 00:21:02,128 --> 00:21:04,364 not farmers. 400 00:21:05,565 --> 00:21:09,901 And looking at the plant remains beyond einkorn reveals 401 00:21:09,902 --> 00:21:12,505 something else about the people who came here. 402 00:21:15,842 --> 00:21:17,209 ANTOLÍN: We've been able 403 00:21:17,210 --> 00:21:20,445 to find different types of plant resources, such as 404 00:21:20,446 --> 00:21:22,481 wild cereals and legumes, 405 00:21:22,482 --> 00:21:27,119 which were harvested mostly in spring and early summer period, 406 00:21:27,120 --> 00:21:29,921 loads of fruits and nuts that would be most 407 00:21:29,922 --> 00:21:33,458 typically harvested by the end of summer and autumn. 408 00:21:33,459 --> 00:21:37,663 ♪ ♪ 409 00:21:37,664 --> 00:21:39,765 NARRATOR: The discovery is forcing researchers 410 00:21:39,766 --> 00:21:41,633 to rethink the traditional view 411 00:21:41,634 --> 00:21:45,003 of the people who visited Göbekli Tepe. 412 00:21:45,004 --> 00:21:47,572 That they were nomadic hunter-gatherers 413 00:21:47,573 --> 00:21:49,608 who camped across the surrounding plains 414 00:21:49,609 --> 00:21:51,177 throughout the year... 415 00:21:52,512 --> 00:21:55,448 ...congregating here for occasional celebrations. 416 00:21:56,716 --> 00:21:58,750 ANTOLÍN: We observe a diversification 417 00:21:58,751 --> 00:22:01,920 of gathered resources that would be available 418 00:22:01,921 --> 00:22:04,322 in different months of the year. 419 00:22:04,323 --> 00:22:06,892 So instead of having a mobile camp 420 00:22:06,893 --> 00:22:09,094 that would allow a population 421 00:22:09,095 --> 00:22:11,830 to follow a resource in the landscape, 422 00:22:11,831 --> 00:22:14,633 this population at Göbekli Tepe, 423 00:22:14,634 --> 00:22:16,968 benefits from a number of resources 424 00:22:16,969 --> 00:22:19,237 that are available in different times of the year, 425 00:22:19,238 --> 00:22:21,540 and that can be stored. 426 00:22:21,541 --> 00:22:24,711 This allows them to actually become sedentary. 427 00:22:27,280 --> 00:22:30,582 NARRATOR: For decades, scientists thought hunter-gatherer societies 428 00:22:30,583 --> 00:22:34,687 always moved with the seasons, following herds of animals. 429 00:22:36,689 --> 00:22:38,690 But now, the finds 430 00:22:38,691 --> 00:22:40,759 at Göbekli Tepe are telling a story 431 00:22:40,760 --> 00:22:42,627 of a settled community 432 00:22:42,628 --> 00:22:45,464 exploiting the abundant wild plant 433 00:22:45,465 --> 00:22:48,034 and animal life that surrounded them. 434 00:22:49,035 --> 00:22:51,871 This was a place to live. 435 00:22:54,207 --> 00:22:57,342 But if hunter-gatherers settled at Göbekli Tepe, 436 00:22:57,343 --> 00:22:59,879 where are their houses? 437 00:23:02,415 --> 00:23:04,116 In one of the structures 438 00:23:04,117 --> 00:23:06,051 clustered around the Special Buildings, 439 00:23:06,052 --> 00:23:09,521 Lee is finding evidence 440 00:23:09,522 --> 00:23:10,890 of daily life. 441 00:23:12,058 --> 00:23:14,326 {\an8}This rectangular structure features 442 00:23:14,327 --> 00:23:17,796 {\an8}numerous elements which are clearly domestic. 443 00:23:17,797 --> 00:23:20,432 This reminds us a bit of a modern home in a way, 444 00:23:20,433 --> 00:23:22,033 We have a bench here to my right, 445 00:23:22,034 --> 00:23:24,102 and in that bench we have actually 446 00:23:24,103 --> 00:23:25,871 a grinding stone. 447 00:23:25,872 --> 00:23:27,806 Whether this was used for actually grinding, 448 00:23:27,807 --> 00:23:29,875 whether it contained liquid, perhaps water, 449 00:23:29,876 --> 00:23:32,511 but it's very much like a worktop with a sink, 450 00:23:32,512 --> 00:23:33,713 if you like. 451 00:23:34,781 --> 00:23:38,850 NARRATOR: And there's another discovery on the opposite side of the room. 452 00:23:38,851 --> 00:23:43,488 CLARE: We've got this Stone Age cupboard ideal for storage 453 00:23:43,489 --> 00:23:45,157 with this wonderful limestone vessel, 454 00:23:45,158 --> 00:23:47,425 so we've got this Stone Age furniture 455 00:23:47,426 --> 00:23:49,928 as it were, and very reminiscent of "The Flintstones" in fact. 456 00:23:49,929 --> 00:23:52,597 So this would have been a household kitchen situation, 457 00:23:52,598 --> 00:23:53,932 perhaps a family unit, 458 00:23:53,933 --> 00:23:55,935 using this space to prepare meals. 459 00:23:57,203 --> 00:23:59,939 All this is pointing to domestic life. 460 00:24:03,376 --> 00:24:05,310 NARRATOR: Lee believes many of the structures 461 00:24:05,311 --> 00:24:08,246 packed on the slopes were homes, 462 00:24:08,247 --> 00:24:11,183 covered spaces for permanent residence, 463 00:24:11,184 --> 00:24:13,852 huddled around the Special Buildings 464 00:24:13,853 --> 00:24:16,556 at the heart of Göbekli Tepe. 465 00:24:17,723 --> 00:24:20,826 When combined with the bone and seed discoveries, 466 00:24:20,827 --> 00:24:24,696 the infrastructure here, with grand ceremonial buildings, 467 00:24:24,697 --> 00:24:27,532 and dedicated living spaces, 468 00:24:27,533 --> 00:24:30,669 hints at a society in transition. 469 00:24:30,670 --> 00:24:34,674 Still foraging, but now more permanent. 470 00:24:37,043 --> 00:24:39,744 CLARE: We're dealing with a very complex settlement structure 471 00:24:39,745 --> 00:24:41,980 very much contrary to what people generally think 472 00:24:41,981 --> 00:24:44,583 when we say Neolithic or Stone Age. 473 00:24:44,584 --> 00:24:47,752 At its peak, if the entire area were to have been occupied, 474 00:24:47,753 --> 00:24:51,056 I wouldn't be surprised if we're looking at anything from 475 00:24:51,057 --> 00:24:54,227 500 to over 1,000 people living at Göbekli Tepe. 476 00:24:56,696 --> 00:24:58,530 NARRATOR: The scale is surprising. 477 00:24:58,531 --> 00:25:01,566 Stretching over 22 acres, 478 00:25:01,567 --> 00:25:04,402 20 monumental buildings and perhaps more 479 00:25:04,403 --> 00:25:07,272 yet to be uncovered. 480 00:25:07,273 --> 00:25:09,507 A settlement that could have supported 481 00:25:09,508 --> 00:25:12,144 more than 1,000 people. 482 00:25:15,481 --> 00:25:17,582 It's just one of a handful of early 483 00:25:17,583 --> 00:25:20,686 neolithic settlements so far discovered in the region. 484 00:25:22,622 --> 00:25:26,092 {\an8}Jericho was big enough for over 2,000 people. 485 00:25:27,994 --> 00:25:31,197 {\an8}Tell Abu Hureyra was home to a few hundred. 486 00:25:34,533 --> 00:25:36,768 {\an8}But if Göbekli Tepe was a settlement 487 00:25:36,769 --> 00:25:39,839 {\an8}where people lived across 1,500 years... 488 00:25:41,540 --> 00:25:43,676 {\an8}...where are their remains? 489 00:25:45,745 --> 00:25:48,213 {\an8}During over 30 years of excavation, 490 00:25:48,214 --> 00:25:51,751 {\an8}only fragments of human bones had been discovered. 491 00:25:53,619 --> 00:25:56,122 {\an8}But more recently, that has changed. 492 00:25:57,323 --> 00:25:59,491 {\an8}Now, in one of the walled structures 493 00:25:59,492 --> 00:26:01,594 {\an8}beyond the special buildings... 494 00:26:02,762 --> 00:26:06,097 {\an8}KINZEL: Yeah, this is quite exciting to see. 495 00:26:06,098 --> 00:26:08,767 NARRATOR: ...the researchers have found a burial site 496 00:26:08,768 --> 00:26:10,468 with human remains. 497 00:26:10,469 --> 00:26:12,270 Yeah, wow. 498 00:26:12,271 --> 00:26:15,740 CLARE: So what we've got here, obviously, is a skull, 499 00:26:15,741 --> 00:26:18,977 and a few long bones here. 500 00:26:18,978 --> 00:26:20,846 So, it's a burial. Really, really exciting to have. 501 00:26:22,114 --> 00:26:25,150 CLARE: So another individual from Göbekli Tepe. 502 00:26:25,151 --> 00:26:26,585 It can tell a story. Yeah. 503 00:26:29,455 --> 00:26:33,358 NARRATOR: It's only the third burial to be discovered at the site. 504 00:26:33,359 --> 00:26:34,626 Human remains are special. 505 00:26:34,627 --> 00:26:36,728 I mean, these are the people that built the site. 506 00:26:36,729 --> 00:26:38,263 These are the people that lived here. 507 00:26:38,264 --> 00:26:42,367 NARRATOR: And Lee sees something right away that could make 508 00:26:42,368 --> 00:26:45,470 these remains even more special. 509 00:26:45,471 --> 00:26:47,305 CLARE: The bones-- they're not fused. 510 00:26:47,306 --> 00:26:48,740 The skull is quite small. 511 00:26:48,741 --> 00:26:50,675 At the moment, we were thinking that 512 00:26:50,676 --> 00:26:52,645 it's probably the remains of a child. 513 00:26:55,481 --> 00:26:58,116 NARRATOR: For Lee and Moritz, the placement of the body 514 00:26:58,117 --> 00:27:01,386 within a decorated niche inside a domestic space 515 00:27:01,387 --> 00:27:03,788 {\an8}gives clues about the belief systems 516 00:27:03,789 --> 00:27:05,691 {\an8}of the people that lived here. 517 00:27:07,126 --> 00:27:10,362 {\an8}KINZEL: By bringing somebody's bones back into the house, 518 00:27:10,363 --> 00:27:12,397 {\an8}it's somehow claiming ownership, 519 00:27:12,398 --> 00:27:15,367 so the dead and the living are living together, 520 00:27:15,368 --> 00:27:17,737 say, they are part of the same cosmos. 521 00:27:20,239 --> 00:27:22,607 NARRATOR: This new discovery adds to 522 00:27:22,608 --> 00:27:24,809 previous analysis of skull fragments 523 00:27:24,810 --> 00:27:26,345 found across the site. 524 00:27:28,214 --> 00:27:29,781 JULIA GRESKY: These pictures are from 525 00:27:29,782 --> 00:27:32,018 the first skull I found in Göbekli Tepe. 526 00:27:33,919 --> 00:27:36,621 NARRATOR: 1,600 miles from the dig, 527 00:27:36,622 --> 00:27:38,490 in her lab in Berlin, 528 00:27:38,491 --> 00:27:40,992 paleopathologist Julia Gresky 529 00:27:40,993 --> 00:27:43,229 has been examining the skull fragments. 530 00:27:44,897 --> 00:27:48,034 Here, we have a lot of wild cut marks. 531 00:27:49,869 --> 00:27:51,369 NARRATOR: At high magnification, 532 00:27:51,370 --> 00:27:53,805 she has identified unnatural markings 533 00:27:53,806 --> 00:27:56,674 on the bone fragments. 534 00:27:56,675 --> 00:27:58,777 {\an8}This is something that you would expect 535 00:27:58,778 --> 00:28:00,112 {\an8}when de-fleshing a skull. 536 00:28:01,414 --> 00:28:04,482 If you want to cut away the soft tissue, 537 00:28:04,483 --> 00:28:06,852 then you would just scrape on the surface. 538 00:28:07,853 --> 00:28:12,090 These incisions were done while the bone was still fresh, 539 00:28:12,091 --> 00:28:14,592 but you can't say that they were done during life, 540 00:28:14,593 --> 00:28:19,231 because there are no signs of healing on this incision. 541 00:28:21,100 --> 00:28:23,001 NARRATOR: The evidence suggests 542 00:28:23,002 --> 00:28:25,904 these skulls were stripped of flesh after death. 543 00:28:25,905 --> 00:28:29,174 And there are more markings. 544 00:28:29,175 --> 00:28:32,143 GRESKY: This skull has three main carvings 545 00:28:32,144 --> 00:28:33,311 on the frontal part. 546 00:28:33,312 --> 00:28:36,414 It is several repeated scratches 547 00:28:36,415 --> 00:28:38,017 in this big line. 548 00:28:39,785 --> 00:28:43,488 NARRATOR: Julia believes these and other marks found on the skull 549 00:28:43,489 --> 00:28:45,925 were made intentionally. 550 00:28:48,727 --> 00:28:50,529 The reason is a mystery. 551 00:28:52,665 --> 00:28:55,900 But another clue has led her to a theory 552 00:28:55,901 --> 00:28:59,437 of how the skulls may have been used. 553 00:28:59,438 --> 00:29:01,906 GRESKY: We found that one of these skulls 554 00:29:01,907 --> 00:29:03,342 had a drilling hole. 555 00:29:06,045 --> 00:29:09,581 {\an8}NARRATOR: The hole was bored through the cranium, 556 00:29:09,582 --> 00:29:12,016 {\an8}right at the top of the skull. 557 00:29:12,017 --> 00:29:15,253 {\an8}GRESKY: Maybe they were trying to fix things on the skulls 558 00:29:15,254 --> 00:29:17,123 or they wanted to hang them with a cord. 559 00:29:18,824 --> 00:29:21,659 NARRATOR: Red marks found on some bone fragments 560 00:29:21,660 --> 00:29:24,195 suggest the skulls could have been decorated 561 00:29:24,196 --> 00:29:26,598 and put on display. 562 00:29:26,599 --> 00:29:28,266 GRESKY: The markings on these skulls, 563 00:29:28,267 --> 00:29:30,702 they point to some ritual tradition, 564 00:29:30,703 --> 00:29:34,105 so a special focus on the skull of these people. 565 00:29:34,106 --> 00:29:35,607 (flames crackling) 566 00:29:35,608 --> 00:29:37,342 NARRATOR: It's possible 567 00:29:37,343 --> 00:29:39,844 a so-called "skull cult" 568 00:29:39,845 --> 00:29:43,014 was practiced by the people of Göbekli Tepe. 569 00:29:43,015 --> 00:29:47,252 GRESKY: A skull cult is a practice of venerating dead people 570 00:29:47,253 --> 00:29:51,189 or memorizing important people of their own family, 571 00:29:51,190 --> 00:29:53,225 of the community in general. 572 00:29:56,195 --> 00:30:00,431 NARRATOR: The skull from the burial shows no signs of decoration. 573 00:30:00,432 --> 00:30:03,168 But the practice of burying bones 574 00:30:03,169 --> 00:30:04,936 within living spaces here 575 00:30:04,937 --> 00:30:07,705 and at later neolithic sites 576 00:30:07,706 --> 00:30:09,707 is a telling clue 577 00:30:09,708 --> 00:30:13,311 about how human societies were changing. 578 00:30:13,312 --> 00:30:17,082 Perhaps the tradition began at Göbekli Tepe. 579 00:30:18,417 --> 00:30:20,785 GRESKY: When people build communities, 580 00:30:20,786 --> 00:30:22,921
