0:00:00.792,0:00:05.768 So I've got something that I'm[br]slightly embarrassed to admit to. 0:00:05.792,0:00:07.351 At the age of 17, 0:00:07.375,0:00:09.184 as a creationist, 0:00:09.208,0:00:12.809 I decided to go to university[br]to study evolution 0:00:12.833,0:00:14.434 so that I could destroy it. 0:00:14.458,0:00:16.143 (Laughter) 0:00:16.167,0:00:17.434 I failed. 0:00:17.458,0:00:21.309 I failed so spectacularly[br]that I'm now an evolutionary biologist. 0:00:21.333,0:00:24.143 (Applause) 0:00:24.167,0:00:27.476 So I'm a paleoanthropologist,[br]I'm a National Geographic Explorer 0:00:27.500,0:00:30.143 specializing in fossil hunting in caves 0:00:30.167,0:00:32.708 in unstable, hostile[br]and disputed territories. 0:00:33.958,0:00:37.476 And we all know that[br]if I was a guy and not a girl, 0:00:37.500,0:00:40.684 that wouldn't be a job description,[br]that would be a pick-up line. 0:00:40.708,0:00:42.893 (Laughter) 0:00:42.917,0:00:45.351 Now, here's the thing.[br]I do not have a death wish. 0:00:45.375,0:00:47.518 I'm not an adrenaline junkie. 0:00:47.542,0:00:50.059 I just looked at a map. 0:00:50.083,0:00:54.309 See, frontline exploratory science[br]does not happen as much 0:00:54.333,0:00:56.833 in politically unstable territories. 0:00:57.542,0:01:01.309 This is a map of all the places[br]which the British Foreign Office 0:01:01.333,0:01:04.518 have declared contain[br]red zones, orange zones 0:01:04.542,0:01:07.809 or have raised some kind[br]of a threat warning about. 0:01:07.833,0:01:11.018 Now I'm going to go out on a limb here[br]and say that it is a tragedy 0:01:11.042,0:01:16.018 if we're not doing frontline exploratory[br]science in a huge portion of the planet. 0:01:16.042,0:01:19.792 And so science has a geography problem. 0:01:20.750,0:01:23.393 Also, as a paleoanthropologist, 0:01:23.417,0:01:26.601 guys, this is basically a map[br]of some of the most important places 0:01:26.625,0:01:28.393 in the human journey. 0:01:28.417,0:01:32.601 There are almost definitely[br]fascinating fossils to be found here. 0:01:32.625,0:01:35.393 But are we looking for them? 0:01:35.417,0:01:38.934 And so as an undergraduate,[br]I was repeatedly told 0:01:38.958,0:01:43.518 that humans, be they ourselves,[br]homo sapiens, or earlier species, 0:01:43.542,0:01:47.125 that we left Africa[br]via the Sinai of Egypt. 0:01:48.250,0:01:51.476 I'm English, as you can[br]probably tell from my accent, 0:01:51.500,0:01:53.518 but I am actually of Arab heritage, 0:01:53.542,0:01:56.226 and I always say that I'm[br]very, very Arab on the outside. 0:01:56.250,0:01:58.059 You know, I can really be passionate. 0:01:58.083,0:01:59.976 Like, "You're amazing! I love you!" 0:02:00.000,0:02:03.226 But on the inside, I'm really English,[br]so everybody irritates me. 0:02:03.250,0:02:05.917 (Laughter) 0:02:08.208,0:02:09.476 It's true. 0:02:09.500,0:02:13.018 And the thing is,[br]my family are Arab from Yemen, 0:02:13.042,0:02:16.643 and I knew that that channel, 0:02:16.667,0:02:18.059 Bab-el-Mandeb, 0:02:18.083,0:02:20.809 is not that much of a feat to cross. 0:02:20.833,0:02:24.601 And I kept asking myself[br]this really simple question: 0:02:24.625,0:02:30.059 if the ancestors to New World monkeys[br]could somehow cross the Atlantic Ocean, 0:02:30.083,0:02:33.625 why couldn't humans cross[br]that tiny stretch of water? 0:02:34.708,0:02:36.351 But the thing is, Yemen, 0:02:36.375,0:02:38.351 compared to, let's say, Europe, 0:02:38.375,0:02:40.434 was so understudied 0:02:40.458,0:02:43.708 that it was something akin[br]to near virgin territory. 0:02:44.917,0:02:51.351 But that, along with its location,[br]made the sheer potential for discovery 0:02:51.375,0:02:53.476 so exciting, 0:02:53.500,0:02:56.351 and I had so many questions. 0:02:56.375,0:02:59.434 When did we first[br]start using Bab-el-Mandeb? 0:02:59.458,0:03:04.226 But also, which species of human[br]besides ourselves made it to Yemen? 0:03:04.250,0:03:08.101 Might we find a species[br]as yet unknown to science? 0:03:08.125,0:03:12.643 And it turned out, I wasn't the only one[br]who had noticed Yemen's potential. 0:03:12.667,0:03:15.309 There was actually[br]a few other academics out there. 0:03:15.333,0:03:20.351 But sadly, due to political instability,[br]they moved out, and so I moved in. 0:03:20.375,0:03:23.559 And I was looking for caves: 0:03:23.583,0:03:28.643 caves because caves[br]are the original prime real estate. 0:03:28.667,0:03:32.643 But also because if you're looking[br]for fossils in that kind of heat, 0:03:32.667,0:03:36.726 your best bet for fossil preservation[br]is always going to be caves. 0:03:36.750,0:03:41.476 But then, Yemen took[br]a really sad turn for the worse, 0:03:41.500,0:03:45.393 and just a few days[br]before I was due to fly out to Yemen, 0:03:45.417,0:03:49.143 the civil war escalated[br]into a regional conflict, 0:03:49.167,0:03:51.268 the capital's airport was bombed 0:03:51.292,0:03:53.542 and Yemen became a no-fly zone. 0:03:56.000,0:04:00.684 Now, my parents made this decision[br]before I was born: 0:04:00.708,0:04:02.583 that I would be born British. 0:04:04.000,0:04:08.000 I had nothing to do[br]with the best decision of my life. 0:04:09.833,0:04:11.268 And now ... 0:04:11.292,0:04:16.434 Now the lucky ones[br]in my family have escaped, 0:04:16.458,0:04:19.351 and the others, the others[br]are being been bombed 0:04:19.375,0:04:23.958 and send you WhatsApp messages[br]that make you detest your very existence. 0:04:27.500,0:04:30.309 This war's been going on for four years. 0:04:30.333,0:04:35.583 It's been going on for over four years,[br]and it has led to a humanitarian crisis. 0:04:36.625,0:04:38.518 There is a famine there, 0:04:38.542,0:04:40.726 a man-made famine. 0:04:40.750,0:04:43.434 That's a man-made famine,[br]so not a natural famine, 0:04:43.458,0:04:47.018 an entirely man-made famine[br]that the UN has warned 0:04:47.042,0:04:51.292 could be the worst famine[br]the world has seen in a hundred years. 0:04:52.417,0:04:55.393 This war has made it[br]clear to me more than ever 0:04:55.417,0:04:59.417 that no place, no people[br]deserve to get left behind. 0:05:01.083,0:05:04.726 And so I was joining these other teams,[br]and I was forming new collaborations 0:05:04.750,0:05:06.934 in other unstable places. 0:05:06.958,0:05:10.059 But I was desperate[br]to get back into Yemen, 0:05:10.083,0:05:13.417 because for me, Yemen's really personal. 0:05:15.083,0:05:20.143 And so I kept trying to think[br]of a project I could do in Yemen 0:05:20.167,0:05:22.917 that would help highlight[br]what was going on there. 0:05:23.875,0:05:27.101 And every idea I had just kept failing, 0:05:27.125,0:05:30.726 or it was just too high-risk,[br]because let's be honest, 0:05:30.750,0:05:34.708 most of Yemen is just too dangerous[br]for a Western team. 0:05:35.875,0:05:41.559 But then I was told that Socotra,[br]a Yemeni island, 0:05:41.583,0:05:44.809 was safe once you got there. 0:05:44.833,0:05:49.101 In fact, it turned out there was a few[br]local and international academics 0:05:49.125,0:05:50.554 that were still working there. 0:05:51.417,0:05:53.417 And that got me really excited, 0:05:54.667,0:05:58.375 because look at Socotra's[br]proximity to Africa. 0:06:00.125,0:06:05.375 And yet we have no idea[br]when humans arrived on that island. 0:06:06.750,0:06:09.476 But Socotra, for those of you who know it, 0:06:09.500,0:06:13.101 well, let's just say you probably know it[br]for a completely different reason. 0:06:13.125,0:06:16.143 You probably know it[br]as the Galapagos of the Indian Ocean, 0:06:16.167,0:06:20.542 because it is one of the most[br]biodiverse places on this earth. 0:06:21.333,0:06:23.768 But we were also getting information 0:06:23.792,0:06:27.309 that this incredibly delicate[br]environment and its people 0:06:27.333,0:06:28.726 were under threat 0:06:28.750,0:06:32.518 because they were at the frontline[br]of both Middle Eastern politics 0:06:32.542,0:06:34.726 and climate change. 0:06:34.750,0:06:40.018 And it slowly dawned on me[br]that Socotra was my Yemen project. 0:06:40.042,0:06:45.059 And so I wanted to put together[br]a huge multidisciplinary team. 0:06:45.083,0:06:49.393 We wanted to cross the archipelago[br]on foot, camel and dhow boat 0:06:49.417,0:06:51.976 to conduct a health check of this place. 0:06:52.000,0:06:55.851 This has only been attempted[br]once before, and it was in 1999. 0:06:55.875,0:07:00.059 But the thing is, that is not[br]an easy thing to pull off. 0:07:00.083,0:07:02.518 And so we desperately needed a recce, 0:07:02.542,0:07:05.476 and for those of you who aren't[br]familiar with British English, 0:07:05.500,0:07:07.351 a recce is like a scouting expedition. 0:07:07.375,0:07:08.893 It's like a reconnaissance. 0:07:08.917,0:07:15.018 And I often say that a really big[br]expedition without a recce 0:07:15.042,0:07:19.184 is a bit like a first date[br]without a Facebook stalk. 0:07:19.208,0:07:20.809 (Laughter) 0:07:20.833,0:07:23.226 Like, it's doable, but is it wise? 0:07:23.250,0:07:27.809 (Laughter) 0:07:27.833,0:07:30.268 There's a few too many[br]knowing laughs in this room. 0:07:30.292,0:07:36.809 Anyway, so then our recce team thankfully[br]were no strangers to unstable places, 0:07:36.833,0:07:38.934 which, let's be honest,[br]is kind of important 0:07:38.958,0:07:42.184 because we were trying to get[br]to a place between Yemen and Somalia, 0:07:42.208,0:07:46.893 And after calling in[br]what felt like a million favors, 0:07:46.917,0:07:49.018 including to the deputy governor, 0:07:49.042,0:07:52.000 we finally found ourselves on the move, 0:07:53.375,0:07:56.893 albeit on a wooden cement cargo ship 0:07:56.917,0:08:00.184 sailing through pirate waters[br]in the Indian Ocean 0:08:00.208,0:08:02.018 with this as a toilet. 0:08:02.042,0:08:03.476 (Laughter) 0:08:03.500,0:08:05.125 Can you guys see this? 0:08:07.125,0:08:10.542 You know how everybody has[br]their worst toilet story? 0:08:11.875,0:08:14.875 Well, I've never swam[br]with dolphins before. 0:08:16.333,0:08:18.518 I just went straight to pooping on them. 0:08:18.542,0:08:20.917 (Laughter) 0:08:23.375,0:08:30.101 And also, I genuinely discovered[br]that I am genuinely less stressed 0:08:30.125,0:08:31.726 by pirate waters 0:08:31.750,0:08:35.308 than I am with a cockroach infestation 0:08:35.332,0:08:37.268 that was so intense 0:08:37.292,0:08:39.601 that at one point I went belowdeck, 0:08:39.625,0:08:42.308 and the floor was black and it was moving. 0:08:42.332,0:08:43.768 (Audience moans) 0:08:43.792,0:08:48.059 Yeah, and at night there was[br]three raised platforms to sleep on, 0:08:48.083,0:08:51.476 but there was only --[br]let's say there was four team members, 0:08:51.500,0:08:54.309 and the thing is, if you got[br]a raised platform to sleep on, 0:08:54.333,0:08:57.601 you only had to contend[br]with a few cockroaches during the night, 0:08:57.625,0:08:59.875 whereas if you got the floor,[br]good luck to you. 0:09:00.875,0:09:04.518 And so I was the only girl in the team[br]and the whole ship, 0:09:04.542,0:09:07.559 so I got away without[br]sleeping on the floor. 0:09:07.583,0:09:09.976 And then, on, like,[br]the fourth or fifth night, 0:09:10.000,0:09:14.667 Martin Edström looks at me and goes,[br]"Ella, Ella I really believe in equality." 0:09:15.167,0:09:18.208 (Laughter) 0:09:19.750,0:09:24.809 So we were sailing on that[br]cement cargo ship for three days, 0:09:24.833,0:09:28.500 and then we slowly started seeing land. 0:09:29.458,0:09:32.018 And after three years of failing, 0:09:32.042,0:09:33.792 I was finally seeing Yemen. 0:09:34.792,0:09:39.518 And there is no feeling on earth[br]like that start of an expedition. 0:09:39.542,0:09:42.768 It's this moment where[br]you jump out of a jeep 0:09:42.792,0:09:45.101 or you look up from a boat 0:09:45.125,0:09:47.934 and you know that[br]there's this possibility, 0:09:47.958,0:09:50.018 it's small but it's still there, 0:09:50.042,0:09:52.226 that you're about to find something 0:09:52.250,0:09:57.476 that could add to or change our knowledge[br]of who we are and where we come from. 0:09:57.500,0:10:00.684 There is no feeling like it on earth, 0:10:00.708,0:10:04.268 and it's a feeling[br]that so many scientists have 0:10:04.292,0:10:08.476 but rarely in politically unstable places. 0:10:08.500,0:10:13.309 Because Western scientists[br]are discouraged or all-out barred 0:10:13.333,0:10:15.750 from working in unstable places. 0:10:16.875,0:10:18.143 But here's the thing: 0:10:18.167,0:10:21.934 scientists specialize in the jungle. 0:10:21.958,0:10:25.726 Scientists work in deep cave systems. 0:10:25.750,0:10:30.351 Scientists attach themselves to rockets[br]and blow themselves into outer space. 0:10:30.375,0:10:32.643 But apparently,[br]working in an unstable place 0:10:32.667,0:10:35.059 is deemed too high-risk. 0:10:35.083,0:10:37.768 It is completely arbitrary. 0:10:37.792,0:10:42.583 Who here in this room[br]wasn't brought up on adventure stories? 0:10:43.167,0:10:47.708 And most of our heroes[br]were actually scientists and academics. 0:10:48.750,0:10:51.893 Science was about going out[br]into the unknown. 0:10:51.917,0:10:57.184 It was about truly global exploration,[br]even if there were risks. 0:10:57.208,0:11:02.601 And so when did it become acceptable[br]to make it difficult for science to happen 0:11:02.625,0:11:04.167 in unstable places? 0:11:05.833,0:11:08.768 And look, I'm not saying[br]that all scientists should go off 0:11:08.792,0:11:10.601 and start working in unstable places. 0:11:10.625,0:11:12.684 This isn't some gung-ho call. 0:11:12.708,0:11:14.250 But here's the thing: 0:11:15.792,0:11:19.917 for those who have done the research,[br]understand security protocol 0:11:20.917,0:11:22.184 and are trained, 0:11:22.208,0:11:24.458 stop stopping those who want to. 0:11:25.083,0:11:26.333 Plus, 0:11:27.417,0:11:31.559 just because one part of a country[br]is an active war zone 0:11:31.583,0:11:33.476 doesn't mean the whole country is. 0:11:33.500,0:11:36.518 I'm not saying we should go[br]into active war zones. 0:11:36.542,0:11:40.042 But Iraqi Kurdistan looks[br]very different from Fallujah. 0:11:40.917,0:11:44.934 And actually, a few months[br]after I couldn't get into Yemen, 0:11:44.958,0:11:46.601 another team adopted me. 0:11:46.625,0:11:51.208 So Professor Graeme Barker's team[br]were actually working in Iraqi Kurdistan, 0:11:52.458,0:11:55.351 and they were digging up Shanidar Cave. 0:11:55.375,0:11:58.434 Now, Shanidar Cave a few decades earlier 0:11:58.458,0:12:02.917 had unveiled a Neanderthal[br]known as Shanidar 1. 0:12:04.042,0:12:08.393 Now, for a BBC/PBS TV series[br]we actually brought Shanidar 1 to life, 0:12:08.417,0:12:11.458 and I want you guys to meet Ned,[br]Ned the Neanderthal. 0:12:13.625,0:12:16.226 Now here's the coolest thing about Ned. 0:12:16.250,0:12:18.351 Ned, this guy, 0:12:18.375,0:12:21.684 you're meeting him before his injuries. 0:12:21.708,0:12:25.976 See, it turned out[br]that Ned was severely disabled. 0:12:26.000,0:12:30.601 He was in fact so disabled that[br]there is no way he could have survived 0:12:30.625,0:12:33.226 without the help of other Neanderthals. 0:12:33.250,0:12:35.018 And so this was proof that, 0:12:35.042,0:12:38.976 at least for this population[br]of Neanderthals at this time, 0:12:39.000,0:12:40.851 Neanderthals were like us, 0:12:40.875,0:12:44.667 and they sometimes looked after[br]those who couldn't look after themselves. 0:12:46.042,0:12:49.309 Ned's an Iraqi Neanderthal. 0:12:49.333,0:12:51.059 So what else are we missing? 0:12:51.083,0:12:53.684 What incredible scientific discoveries 0:12:53.708,0:12:56.542 are we not making[br]because we're not looking? 0:12:58.042,0:13:01.851 And by the way, these places,[br]they deserve narratives of hope, 0:13:01.875,0:13:05.309 and science and exploration[br]can be a part of that. 0:13:05.333,0:13:08.643 In fact, I would argue[br]that it can tangibly aid development, 0:13:08.667,0:13:13.250 and these discoveries[br]become a huge source of local pride. 0:13:13.833,0:13:17.958 And that brings me to the second reason[br]why science has a geography problem. 0:13:19.833,0:13:23.208 See, we don't empower[br]local academics, do we? 0:13:23.875,0:13:25.851 Like, it's not lost on me 0:13:25.875,0:13:28.708 that in my particular field[br]of paleoanthropology 0:13:30.000,0:13:31.893 we study human origins, 0:13:31.917,0:13:35.292 but we have so few diverse scientists. 0:13:36.458,0:13:40.101 And the thing is, these places[br]are full of students and academics 0:13:40.125,0:13:42.518 who are desperate to collaborate, 0:13:42.542,0:13:44.184 and the truth is 0:13:44.208,0:13:45.934 that for them, 0:13:45.958,0:13:48.542 they have fewer security issues than us. 0:13:50.458,0:13:54.351 I think we constantly forget that for them[br]it's not a hostile environment; 0:13:54.375,0:13:55.958 for them it's home. 0:13:57.000,0:13:59.059 I'm telling you, 0:13:59.083,0:14:03.559 research done in unstable places[br]with local collaborators 0:14:03.583,0:14:06.934 can lead to incredible discoveries, 0:14:06.958,0:14:11.458 and that is what we are[br]hoping upon hope to do in Socotra. 0:14:12.875,0:14:14.125 They call Socotra 0:14:15.333,0:14:18.351 the most alien-looking place on earth, 0:14:18.375,0:14:24.018 and myself, Leon McCarron, Martin Edström[br]and Rhys Thwaites-Jones could see why. 0:14:24.042,0:14:25.726 I mean, look at this place. 0:14:25.750,0:14:29.018 These places, they're not hellholes,[br]they're not write-offs, 0:14:29.042,0:14:32.708 they're the future frontline[br]of science and exploration. 0:14:34.042,0:14:36.625 90 percent of the reptiles on this island, 0:14:37.708,0:14:43.309 37 percent of the plant species[br]exist here and nowhere else on earth, 0:14:43.333,0:14:45.893 and that includes this species[br]of dragon's blood tree, 0:14:45.917,0:14:48.125 which actually bleeds this red resin. 0:14:49.000,0:14:50.726 And there's something else. 0:14:50.750,0:14:55.518 People on Socotra,[br]some of them still live in caves, 0:14:55.542,0:14:57.226 and that is really exciting, 0:14:57.250,0:15:00.309 because it means if a cave[br]is prime real estate this century, 0:15:00.333,0:15:02.601 maybe it was a few thousand years ago. 0:15:02.625,0:15:06.559 But we need the data to prove it,[br]the fossils, the stone tools, 0:15:06.583,0:15:10.101 and so our scouting team[br]have teamed up with other scientists, 0:15:10.125,0:15:12.393 anthropologists and storytellers, 0:15:12.417,0:15:15.726 international as well as local,[br]like Ahmed Alarqbi, 0:15:15.750,0:15:18.934 and we are desperate[br]to shed a light on this place 0:15:18.958,0:15:20.833 before it's too late. 0:15:22.667,0:15:26.101 And now, now we just somehow[br]need to get back 0:15:26.125,0:15:28.434 for that really big expedition, 0:15:28.458,0:15:30.143 because science, 0:15:30.167,0:15:32.542 science has a geography problem. 0:15:33.625,0:15:35.726 You guys have been[br]a really lovely audience. 0:15:35.750,0:15:37.018 Thank you. 0:15:37.042,0:15:40.542 (Applause)
