1 00:01:23,918 --> 00:01:26,879 A few days have passed since the battle with the westerners. 2 00:01:29,507 --> 00:01:32,135 And Jackson is still injured. 3 00:01:36,347 --> 00:01:38,558 But an alpha can never show weakness. 4 00:01:58,911 --> 00:02:01,164 {\an8}Jackson's strength is being judged. 5 00:02:08,296 --> 00:02:12,800 For an alpha, physical weakness is also political weakness. 6 00:02:15,761 --> 00:02:17,805 And even Jackson's closest ally 7 00:02:19,140 --> 00:02:20,266 seems more distant. 8 00:02:33,696 --> 00:02:35,448 Abrams and Wilson 9 00:02:36,073 --> 00:02:37,575 can sense an opportunity. 10 00:03:08,314 --> 00:03:09,815 {\an8}With every day that passes, 11 00:03:11,192 --> 00:03:13,945 Christine's baby is becoming more independent. 12 00:03:25,539 --> 00:03:29,877 She's strong and agile enough to make her way through the canopy alone. 13 00:03:35,675 --> 00:03:37,468 And she seems to be showing off. 14 00:04:14,547 --> 00:04:15,673 {\an8}Quite impressive. 15 00:04:24,557 --> 00:04:26,434 The further she gets from her mother, 16 00:04:26,934 --> 00:04:28,644 the more she can get into trouble. 17 00:04:30,146 --> 00:04:31,731 {\an8}And these are turbulent times. 18 00:04:58,299 --> 00:05:00,676 Abrams and Wilson are making their move. 19 00:05:52,269 --> 00:05:54,814 Jackson has been sent running 20 00:05:56,357 --> 00:05:57,942 in full view of the group. 21 00:06:10,246 --> 00:06:11,414 {\an8}With Wilson's help, 22 00:06:12,164 --> 00:06:14,417 {\an8}Abrams has struck a major blow. 23 00:06:33,686 --> 00:06:34,728 And in the forest, 24 00:06:35,688 --> 00:06:36,730 news travels. 25 00:07:05,759 --> 00:07:09,138 The westerners recognize panic and confusion when they hear it. 26 00:07:12,683 --> 00:07:15,519 They can sense weakness in central Ngogo. 27 00:07:44,256 --> 00:07:46,258 {\an8}Abrams now has a decision to make. 28 00:08:28,759 --> 00:08:30,302 He beat Jackson once, 29 00:08:31,178 --> 00:08:32,513 but he paid a price. 30 00:08:42,773 --> 00:08:44,733 And the job is far from finished. 31 00:08:52,116 --> 00:08:54,118 It will take more than one attack 32 00:08:54,618 --> 00:08:56,704 to depose an alpha like Jackson. 33 00:09:45,085 --> 00:09:47,254 Leadership contests are dangerous... 34 00:09:53,677 --> 00:09:55,888 ...for the alpha and for the challenger. 35 00:09:57,598 --> 00:10:00,142 And Abrams has time on his side. 36 00:10:18,118 --> 00:10:20,746 So he's decided to reconcile with Jackson. 37 00:10:30,756 --> 00:10:31,757 It's a truce. 38 00:10:38,931 --> 00:10:39,765 For now. 39 00:11:06,583 --> 00:11:09,044 Peace has been temporarily restored. 40 00:11:17,010 --> 00:11:20,514 So the central group can come together and relax. 41 00:11:40,617 --> 00:11:41,535 For Gus... 42 00:11:43,203 --> 00:11:44,538 ...life is improving. 43 00:11:49,418 --> 00:11:53,380 He's been spending more and more time with Christine and her family. 44 00:12:09,646 --> 00:12:11,690 Christine is comfortable with Gus, 45 00:12:12,191 --> 00:12:15,319 but her attention is being drawn elsewhere. 46 00:12:36,882 --> 00:12:39,635 Gus is still a low-ranking teenager. 47 00:12:40,719 --> 00:12:45,557 Peterson, on the other hand, is a fully grown male with high status. 48 00:13:39,194 --> 00:13:41,154 Chimps change as they get older. 49 00:13:41,822 --> 00:13:44,032 But they never lose their love of playing. 50 00:13:48,912 --> 00:13:51,039 Or their need to be close to each other. 51 00:14:22,362 --> 00:14:23,989 With the truce in place, 52 00:14:23,989 --> 00:14:26,617 Jackson can afford to take time on his own 53 00:14:26,617 --> 00:14:28,410 and recover his strength. 54 00:14:31,580 --> 00:14:33,832 He's come to the edge of the group to rest. 55 00:15:53,704 --> 00:15:58,083 There's virtually zero chance of Jackson grooming Gus back. 56 00:16:09,553 --> 00:16:12,806 Still, any chance to spend time with the alpha 57 00:16:13,765 --> 00:16:14,766 is progress. 58 00:16:31,533 --> 00:16:32,868 A storm is brewing. 59 00:16:37,706 --> 00:16:40,876 And Jackson is returning to the group to sit it out. 60 00:17:51,321 --> 00:17:53,740 {\an8}Heavy rain makes the forest more dangerous. 61 00:17:57,160 --> 00:17:58,870 It's harder to see things coming. 62 00:19:41,181 --> 00:19:42,432 It's the westerners. 63 00:20:12,295 --> 00:20:14,381 Rollins and Damien are closing in. 64 00:20:25,809 --> 00:20:29,354 But this time, it's Richmond who leads the charge. 65 00:21:03,013 --> 00:21:05,056 The central chimps have scattered... 66 00:21:08,893 --> 00:21:11,896 ...and Jackson has been left isolated. 67 00:22:00,028 --> 00:22:02,489 The westerners have Jackson outnumbered. 68 00:22:04,616 --> 00:22:05,867 And he's surrounded. 69 00:23:21,443 --> 00:23:24,195 The other central males have heard Jackson's cries. 70 00:23:26,114 --> 00:23:27,699 {\an8}They're on their way to help. 71 00:23:39,419 --> 00:23:41,796 Richmond has Jackson pinned to the ground. 72 00:24:08,615 --> 00:24:10,492 The westerners have been driven away. 73 00:24:11,242 --> 00:24:12,660 But in the chaos, 74 00:24:13,328 --> 00:24:14,621 Jackson has vanished. 75 00:24:53,910 --> 00:24:55,870 Jackson managed to escape. 76 00:24:58,164 --> 00:24:59,791 But he's been terribly injured. 77 00:25:11,553 --> 00:25:12,804 He's still the alpha... 78 00:25:16,015 --> 00:25:17,016 and even now, 79 00:25:17,976 --> 00:25:20,353 he can't show any weakness to his group. 80 00:25:28,611 --> 00:25:30,697 So he's retreating into the forest, 81 00:25:32,240 --> 00:25:33,074 alone. 82 00:27:00,203 --> 00:27:04,248 Most of the central group don't know what happened in the storm. 83 00:27:10,672 --> 00:27:12,382 Even the chimps that were there 84 00:27:13,591 --> 00:27:15,968 haven't seen Jackson since they were separated. 85 00:27:26,104 --> 00:27:27,980 So life is going on as normal. 86 00:27:36,239 --> 00:27:38,825 But Peterson seems on edge. 87 00:28:07,854 --> 00:28:09,522 He's moving away from the group... 88 00:28:14,110 --> 00:28:15,653 and into the forest. 89 00:29:08,039 --> 00:29:10,583 Jackson has been on his own for a while. 90 00:29:17,799 --> 00:29:20,051 And his injuries aren't improving. 91 00:31:21,130 --> 00:31:22,673 Jackson's strength is fading. 92 00:31:34,977 --> 00:31:36,771 But at least he's no longer alone. 93 00:32:51,721 --> 00:32:53,014 Jackson's passing 94 00:32:53,514 --> 00:32:55,975 marks the end of an era for Ngogo. 95 00:33:02,815 --> 00:33:06,193 For 32 years, he lived here in the forest, 96 00:33:07,028 --> 00:33:08,404 and it was a full life. 97 00:33:11,198 --> 00:33:14,827 He rose to the very top of the biggest chimp group ever known. 98 00:33:17,121 --> 00:33:20,082 And he stayed there for six long years. 99 00:33:24,712 --> 00:33:27,339 But along the way, he made a lot of enemies. 100 00:33:28,507 --> 00:33:30,843 And that cost him his life. 101 00:33:40,144 --> 00:33:41,395 But a chimp's story 102 00:33:41,937 --> 00:33:43,773 doesn't always end with their death. 103 00:33:48,903 --> 00:33:51,822 {\an8}Part of the reason Jackson fought to become alpha 104 00:33:52,531 --> 00:33:54,617 was so he could pass on his legacy. 105 00:33:56,911 --> 00:33:58,579 {\an8}And he was very successful. 106 00:34:03,709 --> 00:34:04,919 He leaves behind 107 00:34:04,919 --> 00:34:06,462 eight children. 108 00:34:09,548 --> 00:34:12,927 And Bartoli has just given birth to a new boy. 109 00:34:14,970 --> 00:34:16,639 He could be Jackson's ninth. 110 00:34:22,895 --> 00:34:24,188 As they grow, 111 00:34:24,188 --> 00:34:26,816 live their lives, and have children of their own, 112 00:34:29,110 --> 00:34:33,155 they'll ensure that Jackson's presence continues to be felt at Ngogo... 113 00:34:35,491 --> 00:34:36,909 long after he's gone. 114 00:35:02,852 --> 00:35:04,145 In the last year, 115 00:35:04,145 --> 00:35:06,647 everything has changed at Ngogo. 116 00:35:15,948 --> 00:35:20,119 The westerners have had a difficult but successful year. 117 00:35:33,007 --> 00:35:35,676 Rollins and Damien have done their job. 118 00:35:37,136 --> 00:35:40,097 Their efforts have helped win new territory... 119 00:35:42,933 --> 00:35:45,060 and the western group continues to grow. 120 00:35:52,443 --> 00:35:54,320 Carson's baby has arrived. 121 00:35:55,154 --> 00:35:57,114 And she'll have to take it easy, 122 00:35:57,698 --> 00:35:58,949 at least for a while. 123 00:36:01,785 --> 00:36:02,828 And Bergl... 124 00:36:05,873 --> 00:36:09,251 is trying to make his own contribution to population growth. 125 00:36:20,137 --> 00:36:23,682 Even Garbo will have seen few years like this one. 126 00:36:27,102 --> 00:36:29,647 And as her long life draws near its end, 127 00:36:30,356 --> 00:36:32,149 her legacy looks more secure. 128 00:36:36,987 --> 00:36:39,448 Her son, Hutcherson, is still the alpha... 129 00:36:42,660 --> 00:36:47,456 and his brother, Richmond, saw the death of Jackson, his old rival. 130 00:36:53,837 --> 00:36:55,798 But even as the group prospers, 131 00:36:56,298 --> 00:36:57,716 only time will tell 132 00:36:57,716 --> 00:37:00,594 whether it was the victory it seems to be. 133 00:37:04,640 --> 00:37:06,183 With Jackson gone, 134 00:37:06,183 --> 00:37:08,978 a new alpha will rise in the central group. 135 00:37:10,938 --> 00:37:13,857 And an alpha with no fear of the westerners 136 00:37:14,608 --> 00:37:17,403 could alter the balance of power at Ngogo. 137 00:37:25,661 --> 00:37:26,870 Whatever happens, 138 00:37:27,538 --> 00:37:29,915 one chimp won't be around to see it. 139 00:37:33,836 --> 00:37:35,337 {\an8}Joya's growing up. 140 00:37:41,302 --> 00:37:42,886 And she must leave Ngogo. 141 00:37:54,648 --> 00:37:58,027 This is how chimp societies mix and remain healthy. 142 00:38:05,784 --> 00:38:08,037 Young females move between groups 143 00:38:09,621 --> 00:38:11,290 to start their own families. 144 00:38:17,296 --> 00:38:19,131 Joya's leaving everything 145 00:38:19,882 --> 00:38:21,467 and everyone she's ever known. 146 00:38:28,766 --> 00:38:30,726 But somewhere out in the forest, 147 00:38:31,352 --> 00:38:32,770 she'll find a new group 148 00:38:33,312 --> 00:38:35,147 where she can build herself a life. 149 00:38:56,835 --> 00:39:00,047 Central Ngogo has lost its alpha. 150 00:39:06,720 --> 00:39:09,473 And the whole group must adjust to life without Jackson. 151 00:39:17,856 --> 00:39:19,733 For Miles, it might mean retirement. 152 00:39:21,819 --> 00:39:23,362 He's been fighting for years. 153 00:39:25,989 --> 00:39:27,616 So he's earned a little peace. 154 00:39:34,915 --> 00:39:38,085 This could be the beginning of the era of Abrams. 155 00:39:39,670 --> 00:39:41,130 Although nothing is certain. 156 00:39:44,091 --> 00:39:46,760 At Ngogo, the politics never stop. 157 00:39:48,053 --> 00:39:50,556 And allies can quickly become rivals 158 00:39:51,890 --> 00:39:53,517 when they see opportunity. 159 00:40:08,449 --> 00:40:10,284 It's been a tough year for Gus. 160 00:40:12,119 --> 00:40:13,662 But he's never given up. 161 00:40:20,127 --> 00:40:21,044 And finally, 162 00:40:21,712 --> 00:40:23,714 he's getting groomed by other males. 163 00:40:34,224 --> 00:40:37,060 Gus is no longer bottom of the pile. 164 00:40:52,910 --> 00:40:55,954 Despite all the turmoil and danger of the last year, 165 00:40:57,456 --> 00:41:00,667 Christine's baby has safely reached her first birthday... 166 00:41:03,378 --> 00:41:04,505 and earned her name. 167 00:41:08,425 --> 00:41:09,259 {\an8}Isobel. 168 00:41:12,554 --> 00:41:14,723 Isobel is now part of the society. 169 00:41:18,894 --> 00:41:21,688 And her life, whatever it has in store for her, 170 00:41:22,731 --> 00:41:24,358 will become a small part 171 00:41:26,026 --> 00:41:27,277 of a bigger story. 172 00:42:04,147 --> 00:42:05,899 Chimps and their ancestors 173 00:42:06,817 --> 00:42:10,153 have lived in the forests of Africa for millions of years. 174 00:42:15,867 --> 00:42:17,286 And for all that time, 175 00:42:17,286 --> 00:42:19,705 stories like these have been unfolding. 176 00:42:23,041 --> 00:42:24,126 Year after year. 177 00:42:28,130 --> 00:42:29,006 Generation... 178 00:42:30,882 --> 00:42:32,009 after generation. 179 00:42:43,061 --> 00:42:44,062 Friendships. 180 00:42:48,317 --> 00:42:49,401 Rivalries. 181 00:42:52,279 --> 00:42:53,113 Hopes. 182 00:42:56,116 --> 00:42:56,950 And fears. 183 00:43:03,874 --> 00:43:05,542 As their closest relatives, 184 00:43:06,627 --> 00:43:08,128 what does this mean for us? 185 00:43:14,092 --> 00:43:14,926 Who are we? 186 00:43:18,930 --> 00:43:21,016 How did we become the way we are? 187 00:43:26,647 --> 00:43:28,732 Chimps can certainly offer clues. 188 00:43:32,653 --> 00:43:36,948 We can often recognize the best and worst of ourselves in them. 189 00:43:42,120 --> 00:43:44,539 If we could fully understand their world... 190 00:43:46,958 --> 00:43:49,086 {\an8}perhaps we could better understand our own. 191 00:43:52,798 --> 00:43:56,843 It seems they always have new and amazing things to show us. 192 00:44:01,098 --> 00:44:03,141 Long may it continue.
