0:00:03 > 0:00:07So far in Life Story,
0:00:07 > 0:00:10we have seen animals face the challenges of childhood...
0:00:12 > 0:00:14..grow up...
0:00:16 > 0:00:18..find their place in the adult world...
0:00:22 > 0:00:24..and win a mate.
0:00:26 > 0:00:30Now, in the final chapter of Life Story,
0:00:30 > 0:00:32animals become parents.
0:00:32 > 0:00:36Their offspring will be their legacy to the future,
0:00:36 > 0:00:38if they can raise them successfully.
0:00:58 > 0:01:00There is no stronger bond in nature
0:01:00 > 0:01:04than that between some parents and their offspring.
0:01:08 > 0:01:10Bonobos in the Congo rainforest.
0:01:10 > 0:01:13They are our closest relatives.
0:01:16 > 0:01:20This mother's youngster is a lifelong commitment.
0:01:20 > 0:01:24He will be totally dependent on her until he's five years old.
0:01:26 > 0:01:30And she will continue to support him for the rest of her life.
0:01:38 > 0:01:42Their relationship may last 30 years.
0:01:48 > 0:01:50Although the length of her commitment is longer
0:01:50 > 0:01:52than for most animals,
0:01:52 > 0:01:57she shares with many other parents the same great challenge -
0:01:57 > 0:02:00keeping her offspring healthy and safe.
0:02:06 > 0:02:11The bond between parents and young will be tested in many ways,
0:02:11 > 0:02:14some minor, and some a matter of life or death.
0:02:20 > 0:02:24And a parent's commitment may begin long before birth.
0:02:26 > 0:02:30The remote northern tip of the Great Barrier Reef.
0:02:36 > 0:02:38After over three decades at sea,
0:02:38 > 0:02:41this female green turtle is returning to the island
0:02:41 > 0:02:43where she hatched.
0:02:45 > 0:02:48It's time for her to lay eggs...
0:02:49 > 0:02:52..but they will only hatch on dry land.
0:02:55 > 0:03:00She must leave the cool sea and enter an alien world.
0:03:20 > 0:03:22Without the support of water,
0:03:22 > 0:03:25she feels the full force of gravity.
0:03:31 > 0:03:33Her flippers, so effective for swimming,
0:03:33 > 0:03:35are almost useless on land.
0:03:39 > 0:03:43But, nonetheless, she has to haul her great weight up the beach
0:03:43 > 0:03:46and get beyond the reach of the tide.
0:03:52 > 0:03:54Turtles time their arrival
0:03:54 > 0:03:57so that their laborious journey up the beach
0:03:57 > 0:04:00is made in the cool of darkness.
0:04:02 > 0:04:04On any one night,
0:04:04 > 0:04:093,000 female turtles may crowd this island to dig their nests.
0:04:17 > 0:04:22Now, her compulsion to leave offspring may cost her her life.
0:04:32 > 0:04:38The receding tide has exposed the reef, a wall of jagged rock.
0:04:56 > 0:04:58It looks an almost impassable barrier
0:04:58 > 0:05:00for an already exhausted turtle.
0:05:04 > 0:05:07But she can't wait for the tide to return,
0:05:07 > 0:05:10because soon the island, under the blazing tropical sun,
0:05:10 > 0:05:13will be intolerably hot.
0:05:29 > 0:05:32Unless she can get over this rocky wall,
0:05:32 > 0:05:35she will be baked in her shell.
0:05:49 > 0:05:55This lethal obstacle course claims many victims every nesting season.
0:06:13 > 0:06:16Just one slip could bring disaster.
0:06:29 > 0:06:30She was so close.
0:06:49 > 0:06:51But all may not be lost.
0:06:59 > 0:07:01The tide is turning.
0:07:09 > 0:07:13If she is completely wedged, she will drown.
0:07:14 > 0:07:17But there is a chance that the rising water could lift her free.
0:08:15 > 0:08:16For this breeding season,
0:08:16 > 0:08:19her obligations as a mother are over.
0:08:23 > 0:08:25She will never see her babies.
0:08:25 > 0:08:29They won't hatch for another two months and, when they do,
0:08:29 > 0:08:33they will have to survive without any help from her.
0:08:40 > 0:08:45Other parents have to remain close to their young at all times,
0:08:45 > 0:08:47to protect them from danger.
0:08:55 > 0:08:58A mother bison in Alberta, Canada.
0:09:00 > 0:09:04Her calf is little more than a week old.
0:09:40 > 0:09:45Wolves, sensibly, select the easiest targets.
0:09:47 > 0:09:48The calves.
0:09:50 > 0:09:55So, bison mothers try to keep their young in the centre of the herd,
0:09:55 > 0:09:56where they are safest.
0:10:03 > 0:10:06But that is not always possible, when the herd is on the run.
0:10:15 > 0:10:17The chase may continue for 20 miles or more,
0:10:17 > 0:10:21as the wolves try to run their targets to exhaustion.
0:10:39 > 0:10:41The wolves make their choice.
0:10:49 > 0:10:53She is on her own, but she's fearless in protecting her calf.
0:10:59 > 0:11:00By keeping her calf close,
0:11:00 > 0:11:04she manages to hold off both of her attackers.
0:11:10 > 0:11:14But another wolf joins in - and she can't fight three.
0:11:22 > 0:11:26Now, the wolves work together to wear her down.
0:11:45 > 0:11:47The forest is not far off.
0:11:47 > 0:11:49If mother and calf can reach the trees,
0:11:49 > 0:11:53they may be able to dodge the wolves for long enough to rejoin the herd.
0:11:59 > 0:12:02But the attack is so unrelenting,
0:12:02 > 0:12:04they can't make a dash for cover.
0:12:15 > 0:12:17The wolves are beginning to tire.
0:12:20 > 0:12:23She sees an opportunity to make a break for it.
0:12:44 > 0:12:47Once again, she blocks the wolves' path...
0:12:55 > 0:12:59..and the wolves lose them amongst the trees.
0:13:23 > 0:13:26But the wolves remain an ever-present threat.
0:13:28 > 0:13:30HOWLING
0:13:32 > 0:13:35And this is unlikely to be the last time
0:13:35 > 0:13:38that this mother will have to fight for her calf.
0:13:46 > 0:13:50The duties of parenthood may seem to be instinctive,
0:13:50 > 0:13:53but there are some skills that have to be learned.
0:14:02 > 0:14:08A troop of Hanuman langurs, 50 strong, living on a cliff in India.
0:14:08 > 0:14:12This is one huge family, with members of all ages.
0:14:14 > 0:14:16But there is only one adult male.
0:14:20 > 0:14:24His scarred face is evidence of his violent past.
0:14:26 > 0:14:28He is the father of all these youngsters.
0:14:33 > 0:14:38Fatherhood, for Scarface, has few duties and many perks.
0:14:44 > 0:14:47He gets plenty of attention from the females...
0:14:54 > 0:14:58..and takes a somewhat hands-off approach to parenting.
0:15:05 > 0:15:07But his protection gives his family
0:15:07 > 0:15:10the safety and the space they need
0:15:10 > 0:15:11to grow and learn.
0:15:16 > 0:15:18The newest addition to the troop.
0:15:24 > 0:15:29The baby is totally dependent on his mother and she dotes on him.
0:15:45 > 0:15:49But becoming a good mother takes practice.
0:15:50 > 0:15:53And a young female, a future parent,
0:15:53 > 0:15:57is learning by playing mum with someone else's baby.
0:16:05 > 0:16:07She seems affectionate enough.
0:16:12 > 0:16:15This is valuable experience for the baby-sitter.
0:16:22 > 0:16:24But now, she starts to play with it.
0:16:36 > 0:16:38And things get quickly out of hand.
0:16:40 > 0:16:42BABY SQUEALS
0:16:50 > 0:16:53She seems to want to shake off the baby.
0:17:05 > 0:17:08Rescue, it seems, is at hand.
0:17:21 > 0:17:23But this isn't the baby's mother,
0:17:23 > 0:17:27it's another learner with even less of a clue than the last.
0:17:35 > 0:17:37Eventually, the baby's real mother
0:17:37 > 0:17:40decides that this game has gone on long enough.
0:17:57 > 0:18:01She rescues her baby and gives it some proper motherly care.
0:18:04 > 0:18:08Perhaps she tolerates the behaviour of these would-be baby-sitters
0:18:08 > 0:18:10because they're close relatives.
0:18:22 > 0:18:25So many females gathered together on this cliff
0:18:25 > 0:18:30inevitably attract the attention of a rival adult male.
0:18:30 > 0:18:35His aim is to defeat Scarface and take over his females.
0:18:43 > 0:18:47He leads a group of outcast bachelors into battle.
0:18:55 > 0:18:57Scarface spots them.
0:18:57 > 0:19:01He has everything to lose, because if the bachelors defeat him,
0:19:01 > 0:19:03they won't just take his females,
0:19:03 > 0:19:05they will kill his babies.
0:19:09 > 0:19:13The bachelors try to reach the high ground to launch their attack.
0:19:22 > 0:19:25Scarface warns them to keep their distance,
0:19:25 > 0:19:27but the bachelors continue their advance.
0:19:30 > 0:19:32HARSH BARKS
0:19:56 > 0:20:00Scarface grinds his teeth, to show he means business.
0:20:04 > 0:20:07But the bachelor leader reaches the cliff top
0:20:07 > 0:20:10and grinds his teeth in response.
0:20:18 > 0:20:22If Scarface loses this battle, he will lose his legacy.
0:20:43 > 0:20:45Time to strike.
0:21:00 > 0:21:02He targets the bachelor leader.
0:21:11 > 0:21:14SCREECHING
0:21:41 > 0:21:43Scarface has won.
0:21:49 > 0:21:51And he returns to a hero's welcome.
0:21:55 > 0:21:58But it's only a temporary respite.
0:22:08 > 0:22:11For a male langur like Scarface,
0:22:11 > 0:22:14parenthood is simple, but dangerous.
0:22:19 > 0:22:23He has banished the bachelors and saved his offspring -
0:22:23 > 0:22:25for now, at least.
0:22:32 > 0:22:36Success for other parents requires total dedication.
0:22:39 > 0:22:41An African drongo.
0:22:44 > 0:22:49She has to shade her three eggs from the scorching heat of the sun.
0:22:53 > 0:22:55As soon as the chicks hatch,
0:22:55 > 0:22:59she will form an immediate bond with them that is unbreakable,
0:22:59 > 0:23:00whatever happens.
0:23:11 > 0:23:14After hundreds of hours of incubation...
0:23:16 > 0:23:18..her first chick.
0:23:26 > 0:23:28Now, the hard work really begins,
0:23:28 > 0:23:31because the newly-hatched chick needs food.
0:23:53 > 0:23:58It won't be long before one mouth is joined by two more
0:23:58 > 0:24:02and this chick will then have to share what the female brings back.
0:24:06 > 0:24:07Or will it?
0:24:24 > 0:24:27The chick is getting rid of any competition.
0:24:29 > 0:24:31It wants its mother's sole attention.
0:24:46 > 0:24:48Feeding time.
0:24:57 > 0:25:00Something has changed. But what?
0:25:10 > 0:25:12FRANTIC CHIRRUPING
0:25:12 > 0:25:15The sight of her chick's bright orange mouth
0:25:15 > 0:25:17demands that she brings more food.
0:25:28 > 0:25:31The egg weighs almost as much as the chick.
0:25:31 > 0:25:33It's like pushing a boulder uphill.
0:25:46 > 0:25:50The chick has a hollow in its back that helps it manoeuvre its load.
0:26:11 > 0:26:15The mother's brood has been reduced to just this one chick
0:26:15 > 0:26:18and it now has her total attention.
0:26:30 > 0:26:35When she's not away gathering food, she shades the chick.
0:26:39 > 0:26:43And she responds instantly whenever it demands to be fed.
0:26:54 > 0:26:56Every day for over three weeks,
0:26:56 > 0:26:58she brings it dozens of meals.
0:27:07 > 0:27:11Her chick never seems to stop eating, or stop growing.
0:27:41 > 0:27:44There is another drongo's nest nearby
0:27:44 > 0:27:47and that has three chicks in it.
0:27:47 > 0:27:50But they don't look quite the same as hers.
0:27:59 > 0:28:03That is because she is raising an alien -
0:28:03 > 0:28:05the chick of a cuckoo.
0:28:12 > 0:28:15Cuckoos lay their eggs in the nests of other birds
0:28:15 > 0:28:19and leave the hard labour of rearing the chick to someone else.
0:28:21 > 0:28:24The cuckoo's egg matched the drongo's egg so perfectly
0:28:24 > 0:28:27that this foster mother has been completely deceived.
0:28:29 > 0:28:33Over at the other drongo nest, the chicks are now fledging.
0:28:36 > 0:28:38Their parents have succeeded
0:28:38 > 0:28:43in producing their very own next generation,
0:28:43 > 0:28:47while she has raised a monster.
0:29:06 > 0:29:08Her love is blind.
0:29:33 > 0:29:34Back in the Congo,
0:29:34 > 0:29:39the mother bonobo's long-term commitment to her baby continues.
0:29:49 > 0:29:51Today, she's demonstrating
0:29:51 > 0:29:55the tricky art of making a bed 30 feet above the ground,
0:29:55 > 0:29:57in preparation for a midday siesta.
0:30:08 > 0:30:11Lesson over, she puts her handiwork to good use.
0:30:20 > 0:30:24For a busy mother, an extra nap is always welcome.
0:30:36 > 0:30:39But Baby seems bored.
0:30:50 > 0:30:53His mother is still the centre of his world
0:30:53 > 0:30:55and his favourite playmate.
0:31:11 > 0:31:15She tries to ignore him, but he won't be put off.
0:31:27 > 0:31:29Eventually, she gives in.
0:31:40 > 0:31:42The whole family is on the move.
0:31:55 > 0:31:57In bonobo society,
0:31:57 > 0:32:00knowledge is passed down from one generation to the next.
0:32:02 > 0:32:04The mothers are going to show their youngsters
0:32:04 > 0:32:08one of the most important places in the forest.
0:32:12 > 0:32:15A special pool, where water lilies grow.
0:32:24 > 0:32:28Water lilies contain minerals important for health,
0:32:28 > 0:32:31and the bonobos can't get them anywhere else.
0:32:56 > 0:32:59Baby learns what to eat by watching Mum.
0:33:06 > 0:33:09And she shares the lily stalks with him.
0:33:21 > 0:33:26She's shown him where to get an important supplement to his diet...
0:33:28 > 0:33:31..and he didn't even have to get his feet wet.
0:33:35 > 0:33:39She will continue to help him to learn about the forest
0:33:39 > 0:33:41for another five years,
0:33:41 > 0:33:44within the protection of his family.
0:33:54 > 0:33:58But few youngsters are raised in such a secure environment.
0:34:20 > 0:34:25The land where this young zebra was born is drying out.
0:34:25 > 0:34:30Its mother must lead it across the river to reach fresh grazing.
0:34:35 > 0:34:37She faces a critical decision.
0:34:40 > 0:34:42Where to cross?
0:34:47 > 0:34:51The life of her six-week-old foal hangs on her decision.
0:35:03 > 0:35:06It's not just crocodiles that pose a threat.
0:35:41 > 0:35:43Crossing here is too dangerous.
0:35:52 > 0:35:57Further downstream. Perhaps this is a better place to cross?
0:36:12 > 0:36:15There are fewer predators, but the river is fast
0:36:15 > 0:36:17and has treacherous rapids.
0:36:31 > 0:36:33It's a difficult decision.
0:36:57 > 0:37:01Once a mother commits herself, she commits her foal,
0:37:01 > 0:37:04and there will be nothing she can do to help it.
0:37:42 > 0:37:46The current is so strong, it carries them downstream,
0:37:46 > 0:37:49through the territory of ill-tempered hippos...
0:37:56 > 0:37:58..and towards the rapids.
0:39:29 > 0:39:32STACCATO BARKING
0:39:58 > 0:40:02The decision to cross here has proved to be a good one,
0:40:02 > 0:40:04but only just.
0:40:25 > 0:40:27This mother has led her foal
0:40:27 > 0:40:30through the most dangerous moment of its young life.
0:40:41 > 0:40:44By keeping her foal safe,
0:40:44 > 0:40:47she has passed this critical test of motherhood.
0:41:04 > 0:41:07Dawn in Amboseli, East Africa.
0:41:14 > 0:41:16A family of elephants.
0:41:27 > 0:41:29The young are sleeping peacefully,
0:41:29 > 0:41:33surrounded by a protective wall of mothers and grandmothers.
0:42:05 > 0:42:10Each morning brings the calves a little closer to independence.
0:42:33 > 0:42:35They may be successful parents,
0:42:35 > 0:42:39but they still have trouble getting the youngsters up in the morning.
0:43:05 > 0:43:10There are three generations in this herd, proof of the family's success.
0:43:25 > 0:43:28They have found the bones of an old female.
0:43:51 > 0:43:56Even the babies are intrigued by these relics of their ancestors.
0:44:11 > 0:44:14We can't, of course, know what they're thinking...
0:44:16 > 0:44:20..but there is a delicacy in the way they touch these bones,
0:44:20 > 0:44:23which suggests that they have some special relevance.
0:44:27 > 0:44:32Perhaps elephants have a sense of a shared history.
0:45:05 > 0:45:09The experience seems to bring them even closer together.
0:45:19 > 0:45:23Every animal in the herd belongs to a family line
0:45:23 > 0:45:26that stretches back through numberless generations.
0:45:38 > 0:45:40And each is here
0:45:40 > 0:45:45because their ancestors were all winners in the game of life.
0:46:00 > 0:46:04An individual animal's chance of success
0:46:04 > 0:46:08varies according to its kind,
0:46:08 > 0:46:11and to the care lavished upon it by its parents.
0:46:19 > 0:46:22Most young bonobos survive childhood.
0:46:26 > 0:46:30But, eventually, each will have to find its own way in the world.
0:46:46 > 0:46:49It may need allies to face up to danger.
0:46:54 > 0:46:58It will have to find its own place in society.
0:47:09 > 0:47:11It will play the mating game...
0:47:16 > 0:47:18..become a parent...
0:47:23 > 0:47:27..and eventually achieve a form of immortality
0:47:27 > 0:47:29by leaving its own offspring.
0:47:39 > 0:47:42No two journeys through life are ever the same...
0:47:46 > 0:47:49..each is as unique as a fingerprint.
0:47:59 > 0:48:02This mother's life has been a success.
0:48:04 > 0:48:09But for each new generation, the journey will begin all over again.
0:48:11 > 0:48:13It's life's great story.
0:48:30 > 0:48:34Bonobos live in the most impenetrable forest on Earth -
0:48:34 > 0:48:35the Congo.
0:48:37 > 0:48:39Cameraman, Rolf Steinmann,
0:48:39 > 0:48:42has worked in some of the world's great open landscapes,
0:48:42 > 0:48:44but never anywhere like this.
0:48:46 > 0:48:49His hope is to film scenes of the bonobos' lives
0:48:49 > 0:48:51that have never been captured before
0:48:51 > 0:48:54and perhaps gain a glimpse into our own past.
0:48:57 > 0:49:00Accompanied by camera assistant, Ed Anderson,
0:49:00 > 0:49:03they journey deep into the African rainforest.
0:49:06 > 0:49:09Despite a 16-mile walk to the research camp,
0:49:09 > 0:49:11Rolf's spirits are high.
0:49:11 > 0:49:14It's really exciting and I think...
0:49:14 > 0:49:18it's definitely the most remote location I have ever walked to.
0:49:21 > 0:49:26The LuiKotale research camp will be their home for the next seven weeks.
0:49:29 > 0:49:31They head out into the forest
0:49:31 > 0:49:35wearing facemasks to protect the bonobos from human diseases.
0:49:41 > 0:49:44They hike over 12 miles, following the bonobos
0:49:44 > 0:49:47and eventually, Rolf gets his first view.
0:49:49 > 0:49:52It was a pretty special day, I would say.
0:49:52 > 0:49:54That was my first bonobo day.
0:49:55 > 0:49:57It was absolutely breathtaking,
0:49:57 > 0:50:00looking into their faces, seeing the babies.
0:50:00 > 0:50:04I mean, you can really feel that they're close relatives to us.
0:50:04 > 0:50:08I mean, it feels like you are surrounded by very little humans.
0:50:11 > 0:50:15But he quickly discovers that such a good day isn't typical.
0:50:15 > 0:50:17HE SIGHS HEAVILY
0:50:17 > 0:50:21There is so much vegetation, I can't get a clear view,
0:50:21 > 0:50:22it's totally impossible.
0:50:32 > 0:50:37And the very density of this forest creates other filming problems.
0:50:37 > 0:50:41We're walking back to camp from the forest,
0:50:41 > 0:50:47it's 3.30pm, this is not a camera effect, it really is this dark.
0:50:47 > 0:50:49When the sun isn't out,
0:50:49 > 0:50:51it feels like the middle of the night sometimes.
0:50:57 > 0:51:01Ed and Rolf's difficulties just continue to mount.
0:51:04 > 0:51:08The bonobos went into the deepest, densest part of the forest,
0:51:08 > 0:51:10it's really hard to follow them.
0:51:13 > 0:51:17The 90% humidity is causing trouble for the camera.
0:51:19 > 0:51:23And worse, they soon encounter some of the other forest inhabitants.
0:51:24 > 0:51:26It's all full of ants here.
0:51:26 > 0:51:29I can't get through there with the big backpack.
0:51:37 > 0:51:39Ants are everywhere!
0:51:41 > 0:51:43Ah, they're biting me everywhere.
0:51:49 > 0:51:52They always want to get to the flesh.
0:51:52 > 0:51:54No, you don't get in there.
0:51:54 > 0:51:56BLEEP! They are biting everywhere!
0:51:56 > 0:52:02Ah, BLEEP! It's not really fun, it's really painful. Go away. Ah. Oh, God.
0:52:06 > 0:52:08I just have to get out of this.
0:52:10 > 0:52:12Wow.
0:52:17 > 0:52:20How should we get rid of all these termites?
0:52:20 > 0:52:21I mean, that is serious.
0:52:23 > 0:52:25The heat and humidity,
0:52:25 > 0:52:29the trekking and the insects are worse than Rolf had feared.
0:52:29 > 0:52:31But causing him most distress
0:52:31 > 0:52:34is hardly ever being able to film the bonobos.
0:52:34 > 0:52:3890% of the things you see, you can't film.
0:52:38 > 0:52:43It's so dark, there's so much vegetation
0:52:43 > 0:52:46and the animals are always in the wrong spot.
0:52:46 > 0:52:49It is pretty much as frustrating as it gets, I think.
0:52:53 > 0:52:57You really have to learn to deal with all the frustration
0:52:57 > 0:53:01and become some kind of Zen master and suppress your emotions.
0:53:02 > 0:53:05Otherwise, you face a high risk here to get insane.
0:53:05 > 0:53:10I am the lucky cameraman. I am the lucky cameraman.
0:53:10 > 0:53:11I am the lucky cameraman.
0:53:21 > 0:53:23Three weeks of trekking
0:53:23 > 0:53:27and finally, the bonobo family appear, briefly, in the open.
0:53:34 > 0:53:38(There the bonobos are, on a log, totally relaxed.
0:53:38 > 0:53:41(I've got my best shots so far, it's amazing!)
0:53:42 > 0:53:44But the bonobos soon disappear again
0:53:44 > 0:53:47and it's back to the daily grind of forest life.
0:53:54 > 0:53:56BUZZING
0:53:58 > 0:54:00Ah, these sweat bees make me crazy.
0:54:06 > 0:54:10The optimism with which they began this shoot is long gone.
0:54:11 > 0:54:15Today, we've already walked 25km
0:54:15 > 0:54:19through some of the densest, thickest jungle so far.
0:54:21 > 0:54:24We didn't get a single shot of the bonobos.
0:54:26 > 0:54:28Yeah, it sometimes feels like a boot camp here.
0:54:29 > 0:54:32Some days...you just want to forget.
0:54:37 > 0:54:40The experience is simply exhausting.
0:54:44 > 0:54:47Finally, the perfect moment.
0:54:52 > 0:54:57Right when we get our first nesting in the daytime,
0:54:57 > 0:54:59really beautiful angle, perfect position,
0:54:59 > 0:55:02the camera stopped working
0:55:02 > 0:55:05and now we have to go back to camp, leaving the bonobos,
0:55:05 > 0:55:08and hope that we can make the camera work again.
0:55:08 > 0:55:11Yeah, don't know really what to say.
0:55:12 > 0:55:14By the time they've got a new camera,
0:55:14 > 0:55:17the bonobos have completely disappeared.
0:55:17 > 0:55:20Paul, Paul, Paul, this is Ed. Paul, Paul, this is Ed.
0:55:20 > 0:55:22Come in, Paul.
0:55:23 > 0:55:25We can't hear them,
0:55:25 > 0:55:27we can't find any tracks,
0:55:27 > 0:55:29so it doesn't look very promising.
0:55:33 > 0:55:35Rolf is hardened to tough conditions,
0:55:35 > 0:55:39but not the frustration of so rarely getting a clear shot.
0:55:45 > 0:55:46Four days later,
0:55:46 > 0:55:48the bonobos have been located,
0:55:48 > 0:55:50but they're on the move.
0:55:52 > 0:55:54They're heading north,
0:55:54 > 0:55:57so there's a good chance that they go into the swamps
0:55:57 > 0:56:01and so, we just speculate and run towards the swamps
0:56:01 > 0:56:03and perhaps we find them there.
0:56:07 > 0:56:08After so much disappointment,
0:56:08 > 0:56:12Rolf and Ed are determined to find them.
0:56:21 > 0:56:25Quite against the odds, their determination pays off.
0:56:26 > 0:56:29Rolf captures the first-ever images
0:56:29 > 0:56:32of a family of bonobos harvesting lilies.
0:56:38 > 0:56:41A scene that feels much like a glimpse into our own past.
0:56:48 > 0:56:51It's everything Rolf had hoped for.
0:56:53 > 0:56:57In this terrain, it's ridiculous that we made it, that is ridiculous!
0:56:57 > 0:56:59It's impossible to film that,
0:56:59 > 0:57:01it's simply impossible and we filmed it!
0:57:01 > 0:57:03I can't believe it, it's so good!
0:57:12 > 0:57:16Our lives may seem very different from those of our closest relatives,
0:57:16 > 0:57:20but beneath the surface, we still share the same challenges
0:57:20 > 0:57:25that every animal faces in its own Life Story.
