for Ngogo. 227 00:33:02,772 --> 00:33:06,150 For 32 years, he lived here in the forest, 228 00:33:06,985 --> 00:33:08,361 and it was a full life. 229 00:33:11,155 --> 00:33:14,784 He rose to the very top of the biggest chimp group ever known. 230 00:33:17,078 --> 00:33:20,039 And he stayed there for six long years. 231 00:33:24,669 --> 00:33:27,296 But along the way, he made a lot of enemies. 232 00:33:28,464 --> 00:33:30,800 And that cost him his life. 233 00:33:38,599 --> 00:33:40,101 [music fading out] 234 00:33:40,184 --> 00:33:41,352 But a chimp's story 235 00:33:41,894 --> 00:33:43,730

00:33:52,488 --> 00:33:54,574 was so he could pass on his legacy. 239 00:33:56,868 --> 00:33:58,536 And he was very successful. 240 00:34:03,666 --> 00:34:04,876 He leaves behind 241 00:34:04,959 --> 00:34:06,419 eight children. 242 00:34:09,505 --> 00:34:12,884 And Bartoli has just given birth to a new boy. 243 00:34:14,927 --> 00:34:16,596 He could be Jackson's ninth. 244 00:34:22,852 -->

Even Garbo will have seen few years like this one. 262 00:36:27,059 --> 00:36:29,604 And as her long life draws near its end, 263 00:36:30,313 --> 00:36:32,106 her legacy looks more secure. 264 00:36:36,944 --> 00:36:39,405 Her son, Hutcherson, is still the alpha... 265 00:36:42,617 --> 00:36:47,413 and his brother, Richmond, saw the death of Jackson, his old rival. 266 00:36:53,794 --> 00:36:55,755 But even as the group prospers, 267 00:36:56,255 --> 00:36:57,673 only time will tell 268 00:36:57,757 --> 00:37:00,551 whether it was the victory it seems to be. 269 00:37:04,597 --> 00:37:06,140 With Jackson gone, 270 00:37:06,224 --> 00:37:08,935 a new alpha will rise in the central group. 271 00:37:10,895 --> 00:37:13,814 And an alpha with no fear of the westerners 272 00:37:14,565 --> 00:37:17,360 could alter the balance of power at Ngogo. 273 00:37:24,533 --> 00:37:25,618 [music fades out] 274 00:37:25,701 --> 00:37:26,827 Whatever happens, 275 00:37:27,495 -->
