1 00:00:00,792 --> 00:00:05,768 So I've got something that I'm slightly embarrassed to admit to. 2 00:00:05,792 --> 00:00:07,351 At the age of 17, 3 00:00:07,375 --> 00:00:09,184 as a creationist, 4 00:00:09,208 --> 00:00:12,809 I decided to go to university to study evolution 5 00:00:12,833 --> 00:00:14,434 so that I could destroy it. 6 00:00:14,458 --> 00:00:16,143 (Laughter) 7 00:00:16,167 --> 00:00:17,434 I failed. 8 00:00:17,458 --> 00:00:21,309 I failed so spectacularly that I'm now an evolutionary biologist. 9 00:00:21,333 --> 00:00:24,143 (Applause) 10 00:00:24,167 --> 00:00:27,476 So I'm a paleoanthropologist, I'm a National Geographic Explorer 11 00:00:27,500 --> 00:00:30,143 specializing in fossil hunting in caves 12 00:00:30,167 --> 00:00:32,708 in unstable, hostile and disputed territories. 13 00:00:33,958 --> 00:00:37,476 And we all know that if I was a guy and not a girl, 14 00:00:37,500 --> 00:00:40,684 that wouldn't be a job description, that would be a pick-up line. 15 00:00:40,708 --> 00:00:42,893 (Laughter) 16 00:00:42,917 --> 00:00:45,351 Now, here's the thing. I do not have a death wish. 17 00:00:45,375 --> 00:00:47,518 I'm not an adrenaline junkie. 18 00:00:47,542 --> 00:00:50,059 I just looked at a map. 19 00:00:50,083 --> 00:00:54,309 See, frontline exploratory science does not happen as much 20 00:00:54,333 --> 00:00:56,833 in politically unstable territories. 21 00:00:57,542 --> 00:01:01,309 This is a map of all the places which the British Foreign Office 22 00:01:01,333 --> 00:01:04,518 have declared contain red zones, orange zones 23 00:01:04,542 --> 00:01:07,809 or have raised some kind of a threat warning about. 24 00:01:07,833 --> 00:01:11,018 Now I'm going to go out on a limb here and say that it is a tragedy 25 00:01:11,042 --> 00:01:16,018 if we're not doing frontline exploratory science in a huge portion of the planet. 26 00:01:16,042 --> 00:01:19,792 And so science has a geography problem. 27 00:01:20,750 --> 00:01:23,393 Also, as a paleoanthropologist, 28 00:01:23,417 --> 00:01:26,601 guys, this is basically a map of some of the most important places 29 00:01:26,625 --> 00:01:28,393 in the human journey. 30 00:01:28,417 --> 00:01:32,601 There are almost definitely fascinating fossils to be found here. 31 00:01:32,625 --> 00:01:35,393 But are we looking for them? 32 00:01:35,417 --> 00:01:38,934 And so as an undergraduate, I was repeatedly told 33 00:01:38,958 --> 00:01:43,518 that humans, be they ourselves, homo sapiens, or earlier species, 34 00:01:43,542 --> 00:01:47,125 that we left Africa via the Sinai of Egypt. 35 00:01:48,250 --> 00:01:51,476 I'm English, as you can probably tell from my accent, 36 00:01:51,500 --> 00:01:53,518 but I am actually of Arab heritage, 37 00:01:53,542 --> 00:01:56,226 and I always say that I'm very, very Arab on the outside. 38 00:01:56,250 --> 00:01:58,059 You know, I can really be passionate. 39 00:01:58,083 --> 00:01:59,976 Like, "You're amazing! I love you!" 40 00:02:00,000 --> 00:02:03,226 But on the inside, I'm really English, so everybody irritates me. 41 00:02:03,250 --> 00:02:05,917 (Laughter) 42 00:02:08,208 --> 00:02:09,476 It's true. 43 00:02:09,500 --> 00:02:13,018 And the thing is, my family are Arab from Yemen, 44 00:02:13,042 --> 00:02:16,643 and I knew that that channel, 45 00:02:16,667 --> 00:02:18,059 Bab-el-Mandeb, 46 00:02:18,083 --> 00:02:20,809 is not that much of a feat to cross. 47 00:02:20,833 --> 00:02:24,601 And I kept asking myself this really simple question: 48 00:02:24,625 --> 00:02:30,059 if the ancestors to New World monkeys could somehow cross the Atlantic Ocean, 49 00:02:30,083 --> 00:02:33,625 why couldn't humans cross that tiny stretch of water? 50 00:02:34,708 --> 00:02:36,351 But the thing is, Yemen, 51 00:02:36,375 --> 00:02:38,351 compared to, let's say, Europe, 52 00:02:38,375 --> 00:02:40,434 was so understudied 53 00:02:40,458 --> 00:02:43,708 that it was something akin to near virgin territory. 54 00:02:44,917 --> 00:02:51,351 But that, along with its location, made the sheer potential for discovery 55 00:02:51,375 --> 00:02:53,476 so exciting, 56 00:02:53,500 --> 00:02:56,351 and I had so many questions. 57 00:02:56,375 --> 00:02:59,434 When did we first start using Bab-el-Mandeb? 58 00:02:59,458 --> 00:03:04,226 But also, which species of human besides ourselves made it to Yemen? 59 00:03:04,250 --> 00:03:08,101 Might we find a species as yet unknown to science? 60 00:03:08,125 --> 00:03:12,643 And it turned out, I wasn't the only one who had noticed Yemen's potential. 61 00:03:12,667 --> 00:03:15,309 There was actually a few other academics out there. 62 00:03:15,333 --> 00:03:20,351 But sadly, due to political instability, they moved out, and so I moved in. 63 00:03:20,375 --> 00:03:23,559 And I was looking for caves: 64 00:03:23,583 --> 00:03:28,643 caves because caves are the original prime real estate. 65 00:03:28,667 --> 00:03:32,643 But also because if you're looking for fossils in that kind of heat, 66 00:03:32,667 --> 00:03:36,726 your best bet for fossil preservation is always going to be caves. 67 00:03:36,750 --> 00:03:41,476 But then, Yemen took a really sad turn for the worse, 68 00:03:41,500 --> 00:03:45,393 and just a few days before I was due to fly out to Yemen, 69 00:03:45,417 --> 00:03:49,143 the civil war escalated into a regional conflict, 70 00:03:49,167 --> 00:03:51,268 the capital's airport was bombed 71 00:03:51,292 --> 00:03:53,542 and Yemen became a no-fly zone. 72 00:03:56,000 --> 00:04:00,684 Now, my parents made this decision before I was born: 73 00:04:00,708 --> 00:04:02,583 that I would be born British. 74 00:04:04,000 --> 00:04:08,000 I had nothing to do with the best decision of my life. 75 00:04:09,833 --> 00:04:11,268 And now ... 76 00:04:11,292 --> 00:04:16,434 Now the lucky ones in my family have escaped, 77 00:04:16,458 --> 00:04:19,351 and the others, the others are being been bombed 78 00:04:19,375 --> 00:04:23,958 and send you WhatsApp messages that make you detest your very existence. 79 00:04:27,500 --> 00:04:30,309 This war's been going on for four years. 80 00:04:30,333 --> 00:04:35,583 It's been going on for over four years, and it has led to a humanitarian crisis. 81 00:04:36,625 --> 00:04:38,518 There is a famine there, 82 00:04:38,542 --> 00:04:40,726 a man-made famine. 83 00:04:40,750 --> 00:04:43,434 That's a man-made famine, so not a natural famine, 84 00:04:43,458 --> 00:04:47,018 an entirely man-made famine that the UN has warned 85 00:04:47,042 --> 00:04:51,292 could be the worst famine the world has seen in a hundred years. 86 00:04:52,417 --> 00:04:55,393 This war has made it clear to me more than ever 87 00:04:55,417 --> 00:04:59,417 that no place, no people deserve to get left behind. 88 00:05:01,083 --> 00:05:04,726 And so I was joining these other teams, and I was forming new collaborations 89 00:05:04,750 --> 00:05:06,934 in other unstable places. 90 00:05:06,958 --> 00:05:10,059 But I was desperate to get back into Yemen, 91 00:05:10,083 --> 00:05:13,417 because for me, Yemen's really personal. 92 00:05:15,083 --> 00:05:20,143 And so I kept trying to think of a project I could do in Yemen 93 00:05:20,167 --> 00:05:22,917 that would help highlight what was going on there. 94 00:05:23,875 --> 00:05:27,101 And every idea I had just kept failing, 95 00:05:27,125 --> 00:05:30,726 or it was just too high-risk, because let's be honest, 96 00:05:30,750 --> 00:05:34,708 most of Yemen is just too dangerous for a Western team. 97 00:05:35,875 --> 00:05:41,559 But then I was told that Socotra, a Yemeni island, 98 00:05:41,583 --> 00:05:44,809 was safe once you got there. 99 00:05:44,833 --> 00:05:49,101 In fact, it turned out there was a few local and international academics 100 00:05:49,125 --> 00:05:50,554 that were still working there. 101 00:05:51,417 --> 00:05:53,417 And that got me really excited, 102 00:05:54,667 --> 00:05:58,375 because look at Socotra's proximity to Africa. 103 00:06:00,125 --> 00:06:05,375 And yet we have no idea when humans arrived on that island. 104 00:06:06,750 --> 00:06:09,476 But Socotra, for those of you who know it, 105 00:06:09,500 --> 00:06:13,101 well, let's just say you probably know it for a completely different reason. 106 00:06:13,125 --> 00:06:16,143 You probably know it as the Galapagos of the Indian Ocean, 107 00:06:16,167 --> 00:06:20,542 because it is one of the most biodiverse places on this earth. 108 00:06:21,333 --> 00:06:23,768 But we were also getting information 109 00:06:23,792 --> 00:06:27,309 that this incredibly delicate environment and its people 110 00:06:27,333 --> 00:06:28,726 were under threat 111 00:06:28,750 --> 00:06:32,518 because they were at the frontline of both Middle Eastern politics 112 00:06:32,542 --> 00:06:34,726 and climate change. 113 00:06:34,750 --> 00:06:40,018 And it slowly dawned on me that Socotra was my Yemen project. 114 00:06:40,042 --> 00:06:45,059 And so I wanted to put together a huge multidisciplinary team. 115 00:06:45,083 --> 00:06:49,393 We wanted to cross the archipelago on foot, camel and dhow boat 116 00:06:49,417 --> 00:06:51,976 to conduct a health check of this place. 117 00:06:52,000 --> 00:06:55,851 This has only been attempted once before, and it was in 1999. 118 00:06:55,875 --> 00:07:00,059 But the thing is, that is not an easy thing to pull off. 119 00:07:00,083 --> 00:07:02,518 And so we desperately needed a recce, 120 00:07:02,542 --> 00:07:05,476 and for those of you who aren't familiar with British English, 121 00:07:05,500 --> 00:07:07,351 a recce is like a scouting expedition. 122 00:07:07,375 --> 00:07:08,893 It's like a reconnaissance. 123 00:07:08,917 --> 00:07:15,018 And I often say that a really big expedition without a recce 124 00:07:15,042 --> 00:07:19,184 is a bit like a first date without a Facebook stalk. 125 00:07:19,208 --> 00:07:20,809 (Laughter) 126 00:07:20,833 --> 00:07:23,226 Like, it's doable, but is it wise? 127 00:07:23,250 --> 00:07:27,809 (Laughter) 128 00:07:27,833 --> 00:07:30,268 There's a few too many knowing laughs in this room. 129 00:07:30,292 --> 00:07:36,809 Anyway, so then our recce team thankfully were no strangers to unstable places, 130 00:07:36,833 --> 00:07:38,934 which, let's be honest, is kind of important 131 00:07:38,958 --> 00:07:42,184 because we were trying to get to a place between Yemen and Somalia, 132 00:07:42,208 --> 00:07:46,893 And after calling in what felt like a million favors, 133 00:07:46,917 --> 00:07:49,018 including to the deputy governor, 134 00:07:49,042 --> 00:07:52,000 we finally found ourselves on the move, 135 00:07:53,375 --> 00:07:56,893 albeit on a wooden cement cargo ship 136 00:07:56,917 --> 00:08:00,184 sailing through pirate waters in the Indian Ocean 137 00:08:00,208 --> 00:08:02,018 with this as a toilet. 138 00:08:02,042 --> 00:08:03,476 (Laughter) 139 00:08:03,500 --> 00:08:05,125 Can you guys see this? 140 00:08:07,125 --> 00:08:10,542 You know how everybody has their worst toilet story? 141 00:08:11,875 --> 00:08:14,875 Well, I've never swam with dolphins before. 142 00:08:16,333 --> 00:08:18,518 I just went straight to pooping on them. 143 00:08:18,542 --> 00:08:20,917 (Laughter) 144 00:08:23,375 --> 00:08:30,101 And also, I genuinely discovered that I am genuinely less stressed 145 00:08:30,125 --> 00:08:31,726 by pirate waters 146 00:08:31,750 --> 00:08:35,308 than I am with a cockroach infestation 147 00:08:35,332 --> 00:08:37,268 that was so intense 148 00:08:37,292 --> 00:08:39,601 that at one point I went belowdeck, 149 00:08:39,625 --> 00:08:42,308 and the floor was black and it was moving. 150 00:08:42,332 --> 00:08:43,768 (Audience moans) 151 00:08:43,792 --> 00:08:48,059 Yeah, and at night there was three raised platforms to sleep on, 152 00:08:48,083 --> 00:08:51,476 but there was only -- let's say there was four team members, 153 00:08:51,500 --> 00:08:54,309 and the thing is, if you got a raised platform to sleep on, 154 00:08:54,333 --> 00:08:57,601 you only had to contend with a few cockroaches during the night, 155 00:08:57,625 --> 00:08:59,875 whereas if you got the floor, good luck to you. 156 00:09:00,875 --> 00:09:04,518 And so I was the only girl in the team and the whole ship, 157 00:09:04,542 --> 00:09:07,559 so I got away without sleeping on the floor. 158 00:09:07,583 --> 00:09:09,976 And then, on, like, the fourth or fifth night, 159 00:09:10,000 --> 00:09:14,667 Martin Edström looks at me and goes, "Ella, Ella I really believe in equality." 160 00:09:15,167 --> 00:09:18,208 (Laughter) 161 00:09:19,750 --> 00:09:24,809 So we were sailing on that cement cargo ship for three days, 162 00:09:24,833 --> 00:09:28,500 and then we slowly started seeing land. 163 00:09:29,458 --> 00:09:32,018 And after three years of failing, 164 00:09:32,042 --> 00:09:33,792 I was finally seeing Yemen. 165 00:09:34,792 --> 00:09:39,518 And there is no feeling on earth like that start of an expedition. 166 00:09:39,542 --> 00:09:42,768 It's this moment where you jump out of a jeep 167 00:09:42,792 --> 00:09:45,101 or you look up from a boat 168 00:09:45,125 --> 00:09:47,934 and you know that there's this possibility, 169 00:09:47,958 --> 00:09:50,018 it's small but it's still there, 170 00:09:50,042 --> 00:09:52,226 that you're about to find something 171 00:09:52,250 --> 00:09:57,476 that could add to or change our knowledge of who we are and where we come from. 172 00:09:57,500 --> 00:10:00,684 There is no feeling like it on earth, 173 00:10:00,708 --> 00:10:04,268 and it's a feeling that so many scientists have 174 00:10:04,292 --> 00:10:08,476 but rarely in politically unstable places. 175 00:10:08,500 --> 00:10:13,309 Because Western scientists are discouraged or all-out barred 176 00:10:13,333 --> 00:10:15,750 from working in unstable places. 177 00:10:16,875 --> 00:10:18,143 But here's the thing: 178 00:10:18,167 --> 00:10:21,934 scientists specialize in the jungle. 179 00:10:21,958 --> 00:10:25,726 Scientists work in deep cave systems. 180 00:10:25,750 --> 00:10:30,351 Scientists attach themselves to rockets and blow themselves into outer space. 181 00:10:30,375 --> 00:10:32,643 But apparently, working in an unstable place 182 00:10:32,667 --> 00:10:35,059 is deemed too high-risk. 183 00:10:35,083 --> 00:10:37,768 It is completely arbitrary. 184 00:10:37,792 --> 00:10:42,583 Who here in this room wasn't brought up on adventure stories? 185 00:10:43,167 --> 00:10:47,708 And most of our heroes were actually scientists and academics. 186 00:10:48,750 --> 00:10:51,893 Science was about going out into the unknown. 187 00:10:51,917 --> 00:10:57,184 It was about truly global exploration, even if there were risks. 188 00:10:57,208 --> 00:11:02,601 And so when did it become acceptable to make it difficult for science to happen 189 00:11:02,625 --> 00:11:04,167 in unstable places? 190 00:11:05,833 --> 00:11:08,768 And look, I'm not saying that all scientists should go off 191 00:11:08,792 --> 00:11:10,601 and start working in unstable places. 192 00:11:10,625 --> 00:11:12,684 This isn't some gung-ho call. 193 00:11:12,708 --> 00:11:14,250 But here's the thing: 194 00:11:15,792 --> 00:11:19,917 for those who have done the research, understand security protocol 195 00:11:20,917 --> 00:11:22,184 and are trained, 196 00:11:22,208 --> 00:11:24,458 stop stopping those who want to. 197 00:11:25,083 --> 00:11:26,333 Plus, 198 00:11:27,417 --> 00:11:31,559 just because one part of a country is an active war zone 199 00:11:31,583 --> 00:11:33,476 doesn't mean the whole country is. 200 00:11:33,500 --> 00:11:36,518 I'm not saying we should go into active war zones. 201 00:11:36,542 --> 00:11:40,042 But Iraqi Kurdistan looks very different from Fallujah. 202 00:11:40,917 --> 00:11:44,934 And actually, a few months after I couldn't get into Yemen, 203 00:11:44,958 --> 00:11:46,601 another team adopted me. 204 00:11:46,625 --> 00:11:51,208 So Professor Graeme Barker's team were actually working in Iraqi Kurdistan, 205 00:11:52,458 --> 00:11:55,351 and they were digging up Shanidar Cave. 206 00:11:55,375 --> 00:11:58,434 Now, Shanidar Cave a few decades earlier 207 00:11:58,458 --> 00:12:02,917 had unveiled a Neanderthal known as Shanidar 1. 208 00:12:04,042 --> 00:12:08,393 Now, for a BBC/PBS TV series we actually brought Shanidar 1 to life, 209 00:12:08,417 --> 00:12:11,458 and I want you guys to meet Ned, Ned the Neanderthal. 210 00:12:13,625 --> 00:12:16,226 Now here's the coolest thing about Ned. 211 00:12:16,250 --> 00:12:18,351 Ned, this guy, 212 00:12:18,375 --> 00:12:21,684 you're meeting him before his injuries. 213 00:12:21,708 --> 00:12:25,976 See, it turned out that Ned was severely disabled. 214 00:12:26,000 --> 00:12:30,601 He was in fact so disabled that there is no way he could have survived 215 00:12:30,625 --> 00:12:33,226 without the help of other Neanderthals. 216 00:12:33,250 --> 00:12:35,018 And so this was proof that, 217 00:12:35,042 --> 00:12:38,976 at least for this population of Neanderthals at this time, 218 00:12:39,000 --> 00:12:40,851 Neanderthals were like us, 219 00:12:40,875 --> 00:12:44,667 and they sometimes looked after those who couldn't look after themselves. 220 00:12:46,042 --> 00:12:49,309 Ned's an Iraqi Neanderthal. 221 00:12:49,333 --> 00:12:51,059 So what else are we missing? 222 00:12:51,083 --> 00:12:53,684 What incredible scientific discoveries 223 00:12:53,708 --> 00:12:56,542 are we not making because we're not looking? 224 00:12:58,042 --> 00:13:01,851 And by the way, these places, they deserve narratives of hope, 225 00:13:01,875 --> 00:13:05,309 and science and exploration can be a part of that. 226 00:13:05,333 --> 00:13:08,643 In fact, I would argue that it can tangibly aid development, 227 00:13:08,667 --> 00:13:13,250 and these discoveries become a huge source of local pride. 228 00:13:13,833 --> 00:13:17,958 And that brings me to the second reason why science has a geography problem. 229 00:13:19,833 --> 00:13:23,208 See, we don't empower local academics, do we? 230 00:13:23,875 --> 00:13:25,851 Like, it's not lost on me 231 00:13:25,875 --> 00:13:28,708 that in my particular field of paleoanthropology 232 00:13:30,000 --> 00:13:31,893 we study human origins, 233 00:13:31,917 --> 00:13:35,292 but we have so few diverse scientists. 234 00:13:36,458 --> 00:13:40,101 And the thing is, these places are full of students and academics 235 00:13:40,125 --> 00:13:42,518 who are desperate to collaborate, 236 00:13:42,542 --> 00:13:44,184 and the truth is 237 00:13:44,208 --> 00:13:45,934 that for them, 238 00:13:45,958 --> 00:13:48,542 they have fewer security issues than us. 239 00:13:50,458 --> 00:13:54,351 I think we constantly forget that for them it's not a hostile environment; 240 00:13:54,375 --> 00:13:55,958 for them it's home. 241 00:13:57,000 --> 00:13:59,059 I'm telling you, 242 00:13:59,083 --> 00:14:03,559 research done in unstable places with local collaborators 243 00:14:03,583 --> 00:14:06,934 can lead to incredible discoveries, 244 00:14:06,958 --> 00:14:11,458 and that is what we are hoping upon hope to do in Socotra. 245 00:14:12,875 --> 00:14:14,125 They call Socotra 246 00:14:15,333 --> 00:14:18,351 the most alien-looking place on earth, 247 00:14:18,375 --> 00:14:24,018 and myself, Leon McCarron, Martin Edström and Rhys Thwaites-Jones could see why. 248 00:14:24,042 --> 00:14:25,726 I mean, look at this place. 249 00:14:25,750 --> 00:14:29,018 These places, they're not hellholes, they're not write-offs, 250 00:14:29,042 --> 00:14:32,708 they're the future frontline of science and exploration. 251 00:14:34,042 --> 00:14:36,625 90 percent of the reptiles on this island, 252 00:14:37,708 --> 00:14:43,309 37 percent of the plant species exist here and nowhere else on earth, 253 00:14:43,333 --> 00:14:45,893 and that includes this species of dragon's blood tree, 254 00:14:45,917 --> 00:14:48,125 which actually bleeds this red resin. 255 00:14:49,000 --> 00:14:50,726 And there's something else. 256 00:14:50,750 --> 00:14:55,518 People on Socotra, some of them still live in caves, 257 00:14:55,542 --> 00:14:57,226 and that is really exciting, 258 00:14:57,250 --> 00:15:00,309 because it means if a cave is prime real estate this century, 259 00:15:00,333 --> 00:15:02,601 maybe it was a few thousand years ago. 260 00:15:02,625 --> 00:15:06,559 But we need the data to prove it, the fossils, the stone tools, 261 00:15:06,583 --> 00:15:10,101 and so our scouting team have teamed up with other scientists, 262 00:15:10,125 --> 00:15:12,393 anthropologists and storytellers, 263 00:15:12,417 --> 00:15:15,726 international as well as local, like Ahmed Alarqbi, 264 00:15:15,750 --> 00:15:18,934 and we are desperate to shed a light on this place 265 00:15:18,958 --> 00:15:20,833 before it's too late. 266 00:15:22,667 --> 00:15:26,101 And now, now we just somehow need to get back 267 00:15:26,125 --> 00:15:28,434 for that really big expedition, 268 00:15:28,458 --> 00:15:30,143 because science, 269 00:15:30,167 --> 00:15:32,542 science has a geography problem. 270 00:15:33,625 --> 00:15:35,726 You guys have been a really lovely audience. 271 00:15:35,750 --> 00:15:37,018 Thank you. 272 00:15:37,042 --> 00:15:40,542 (Applause)
