0:00When we made videos about the canine and
0:02feline family trees and released these
0:04accompanying beautiful posters, one
0:06follow-up request rose to the top. Apes.
0:09Hi, I'm David and this is Planet of the
0:12Apes. Apes split off from monkeys around
0:1425 to 30 million years ago. The simplest
0:16way to tell the difference between apes
0:18and monkeys is that apes are generally
0:20bigger and don't have tails. But there
0:22are a few exceptions. This is an ape,
0:24and so is this. And so is this. And so
0:26are all of these beautiful primates. And
0:28hey, we are all apes, too. And in this
0:31video, I'm going to take you on a tour
0:33of all of your cousins and show off the
0:34poster we made to celebrate them. Okay,
0:37let's start off with a few of our
0:38favorite extinct apes. The largest ape
0:40to ever exist was Gigantoythecus, a
0:4310-ft tall half-tonon behemoth who lived
0:45in the forests of southern China until
0:47around 300,000 years ago. You're going
0:49to hear about a lot of pythecuses in
0:51this video, by the way, since it's a
0:52root term that basically means primate.
0:54Despite its well giganticness,
0:56Gigantoythecus was likely a pretty chill
0:59vegetarian that spent most of its time
1:00gnawing on bamboo. One of the strangest
1:03extinct apes to ever exist was
1:05Oreopythecus, who developed some really
1:07weird adaptations while living on a
1:09predator-free island in the
1:10Mediterranean 6 to 8 million years ago.
1:12First off, it had flat feet and short,
1:14robust legs, probably because it spent a
1:16lot of the time out in the open walking
1:18around on two feet, about 4 million
1:20years before any other ape did. Second,
1:22it had incredibly long arms, which
1:24helped it reach into mucky bogs and grab
1:26its favorite food, swamp grass. Let's go
1:29back a little farther in time, 25
1:31million years ago, to meet
1:33Rukquapythecus. It was tiny, barely 5
1:36kilos, and it lived in the woodlands of
1:38what is now Tanzania. But the
1:39researchers who found its fossils
1:41realized that it was a long missing link
1:42between monkeys and people. In other
1:44words, it was one of the very first
1:46apes. So, let's go through
1:48Rukquipythecus' living relatives, the
1:50current ape family tree. There are two
1:52branches, the great apes, which are
1:54bigger, and the lesser apes, which are
1:56smaller. You'll notice there are way
1:58more lesser ape species than great ape
2:00species. That's because for reasons
2:02scientists don't really understand yet.
2:04The lesser apes are super prone to
2:05chromosome rearrangements, which means
2:07that when a population splinters from
2:08the main group, it often evolves a new
2:10number of chromosomes, making it unable
2:12to interbreed with the species it came
2:13from. Okay, let's start with the lesser
2:16apes. The l gibbon, which lives mostly
2:18in Thailand, is the gibbon you are
2:20probably most familiar with, as it's the
2:21most common one in zoos, and it's a
2:24kuner. Every morning, mating pairs sing
2:26duets to one another across the forest.
2:28Recently, researchers learned that these
2:30songs don't just serve as a love
2:31language. They also include info about
2:33predators in the area. The agile gibbon
2:35and the borne white-bearded gibbon are
2:37some of the best athletes in the ape
2:38family. When these gibbons swing through
2:40the trees, they can reach speeds of up
2:42to 55 km/h as they move between the
2:44branches, and they can leap more than 15
2:46m. That's the length of a semi-trail.
2:49There are lots of other similar looking
2:50gibbons on this branch, like the three
2:52different types of gray gibbons that
2:54live in Borneo, and Claus's gibbons that
2:56live on the Mento Islands off the west
2:57coast of Sumatra and the silvery gibbons
3:00that live on the island of Java. In some
3:02gibbon species, the males and the
3:03females look totally different. Take the
3:05piated gibbons of Thailand and Cambodia.
3:08Male piated gibbons are black with a
3:10ring around their face, while females
3:12are tan with a black face and chest. In
3:14most species of hoolock gibbons, which
3:16live farther north in India and China,
3:17the males are black with white eyebrows,
3:19while the females are light brown with a
3:21darker face. One species, the Skywalker
3:24hoolock gibbon, was only discovered by
3:26scientists 10 years ago, making it the
3:28most recent addition to the entire tree.
3:30And yes, those researchers were massive
3:32Star Wars nerds. Now, let's check out
3:34this bow of the gibbon branch of the
3:36tree, the crested gibbons, which are
3:37called that because it looks like
3:38they've got these little mohawks on top
3:40of their heads. The three crested
3:41gibbons species, the black crested
3:43gibbon, the eastern black crested
3:45gibbon, and the hain black crested
3:46gibbon, all live in northern Vietnam or
3:48China. While all other gibbons live in
3:50pairs, the crested gibbons are a little
3:52laxer about this whole monogamy thing
3:54and sometimes live in one male
3:55multi-female groups. The Heinen black
3:57crested gibbon is likely the most
3:59endangered primate in the world. Thanks
4:01to deforestation, there are fewer than
4:0250 of them left in the wild. Then there
4:05are the cheicked gibbons, known for the
4:06cool facial roughs that both the males
4:08and the females sport. The northern
4:09buffed cheek gibbon, the southern white
4:12cheicked gibbon, the northern white
4:13cheicked gibbon, and the yellow cheicked
4:15gibbon all stay high up in the canopy of
4:17the forests of Laos, Cambodia, and
4:18Vietnam, likely to keep away from the
4:20clouded leopards and pythons that patrol
4:22the lower branches. Finally, there's the
4:24last bow of the lesser eight branch,
4:25which contains only one member, the
4:27Siang. The Siameang, which lives in
4:29Thailand, Malaysia, and Indonesia, is by
4:32far the biggest of the lesser apes. At
4:34up to 15 kilos, it's twice the size of
4:36the others. In addition, it has an
4:37inflatable throat sack that it uses to
4:39magnify its songs across the forests.
4:41That's all the lesser apes, given or
4:43take a few. All right, now let's head on
4:45over to the other side of the tree, the
4:47great apes. The great ape that we're
4:49least related to is the orangutane,
4:50which gets its name from the Malay words
4:52for forest and person. The Borneian
4:55orangutane was made famous by Barut
4:56Galdigos who has been studying these
4:58solitary animals for more than 50 years.
5:00Male Borneian oranges, at least the
5:02bigger dominant ones, develop
5:04distinctive wide facial plates and
5:06regularly come down to the ground to eat
5:07fallen fruit, while the less dominant
5:09males and the females stay protected up
5:11in the trees. The Sumatran orangutane is
5:13less likely to come to the ground to
5:15eat, probably because there are lots of
5:17hungry tigers around. The Tapanoli
5:19orangutane also lives in Sumatra, but
5:21just in one tiny isolated corner. It's a
5:23little bit paler than the sumashian one.
5:24It's also the rarest great ape. There
5:26are likely less than a thousand of them.
5:28Okay, let's get into the gorillas. Most
5:30western gorillas live in the lowland
5:32rainforests of the Republic of Congo and
5:34live in groups of several females and
5:36one dominant male who's called a
5:37silverback. These gorillas weigh up to
5:39100 kilos, and they're pretty clever.
5:41They've been seen using sticks to
5:43measure the depths of streams before
5:44they try to cross them. Eastern gorillas
5:46live in Rwanda, Uganda, and the
5:48Democratic Republic of Congo. The most
5:50famous eastern gorillas are the mountain
5:52gorillas. Made famous by primatologist
5:54Diane FSY. They are huge. Silverback
5:57males can weigh more than $200 kg, but
5:59are known as peaceful giants who
6:01tolerate the presence of humans. In
6:02fact, mountain gorilla tourism is a
6:04giant business. It generates more than
6:06$60 million a year. Ooh. Ooh. Now we're
6:09getting somewhere. We've arrived at our
6:11closest living relatives, the bonobos
6:13and chimpanzees, who diverged from us
6:14humans just 5 or so million years ago.
6:16Bonobos and chimps split off from one
6:18another just over a million years ago
6:19thanks to the widening Congo River which
6:21split the two groups apart. We made a
6:23whole video about that. Because the
6:25bonobos didn't have to compete with
6:26gorillas for food, they ended up
6:28peaceful and relatively bohemian,
6:30settling most of their disputes with um
6:32snuggles. The most famous bonobo was
6:34Kanzi, who wowed researchers by quickly
6:36learning to use a modified form of
6:37language to communicate complex ideas.
6:39He was also an avid gamer. He especially
6:41liked playing Minecraft. Unlike the
6:43hippie bonobos, chimpanzees have no
6:45qualms about resorting to violence. The
6:47group I used to study in Uganda would
6:49regularly go out on patrols looking for
6:51males from other groups to beat up or
6:52even kill. Chimps also have intricate
6:54cultural traditions that they would pass
6:56down from one generation to another.
6:58Primatologist Jane Goodall found that
6:59chimp moms would teach their children
7:01how to fashion twigs in just the right
7:03way to successfully fish for termites.
7:05Before we get to the last remaining
7:06living ape, you know, humans, let's talk
7:09about what happened way back when after
7:10the human and chimp lineages split. One
7:13of the first homminids to walk upright
7:14was Oralopythecus Apparensis. Hey,
7:17there's that Pythecus route again. The
7:19most well-known Oralopiththesine is
7:21Lucy, who was named after the Beatles
7:22song that the scientists played on
7:24repeat while she was excavated from a
7:25valley in Ethiopia. Lucy and her
7:27relatives were pretty small, around 4t
7:29tall, and mostly ate fruit, seeds, and
7:32roots. About 2 and a half million years
7:34ago, Homohabilis evolved in eastern and
7:36southern Africa. They were bigger than
7:37the oralopithesines and were the first
7:39hominids to make basic stone tools.
7:41There's evidence that Homohabilis was a
7:43scavenger. It would scare off hyenas and
7:45lions from kills and then use those
7:46stone tools to hack off meat and bones
7:48to munch on. Then about 2 million years
7:51ago, not too long before Homohabilis
7:53went extinct, Homo Erectus evolved.
7:55Erectus basically looked like a modern
7:57human with long legs capable of walking
7:58extremely long distances. It was the
8:00first homminid to make its way out of
8:01Africa and into Asia and Europe. Erectus
8:04was also the first homminid to learn how
8:05to make fire and to take down big
8:07animals by themselves. Modern Homo
8:09sapiens likely evolved from a branch of
8:11the Homoctus tree. But our species
8:13wasn't the only human species to split
8:14off. In fact, around a couple hundred
8:16thousand years ago, Homo sapiens shared
8:18the Earth with several other human
8:19species, not to mention the bands of
8:21Homoctus that were still around. Let's
8:23meet our neighbors. The other human
8:25species you're probably most familiar
8:26with is the Neanderthalss. You've
8:28probably heard about how big and strong
8:29they were, and they needed to be in
8:31order to survive the cold in Northern
8:32Europe and to hunt down the woolly
8:34mammoths that made up most of their
8:35diet. They also painted the caves where
8:37they live. At the same time, the
8:38Dennisovvens ranged across Asia and a
8:40little bit of Europe. They were as big
8:42as the Neanderthalss, but looked a
8:43little different, likely because they
8:44evolved adaptations to help them live
8:46high up in the mountains. They also
8:47liked making jewelry and bracelets.
8:49There's evidence that the Dennisovvens
8:50and the Neanderthalss occasionally
8:52overlapped. In fact, at one cave in
8:54Siberia, researchers found a human with
8:55DNA that showed she had a Dennisovven
8:57father and a Neanderthal mother.
8:59Homohidlebergensis lived in southern
9:01Europe around the same time. They were
9:03likely taller than the other groups of
9:04humans living around and also relied on
9:06hunting big game for food.
9:07Hidlebergensis specialized in taking
9:09down the straight tusked elephants that
9:11lived in that area. At around the same
9:12time, there was also a species of tiny
9:14humans, Homo Floresensus, that lived on
9:17an isolated island in Indonesia. Despite
9:19being only 3 and 1/2 ft tall, these
9:21islanders were able to successfully hunt
9:22the local elephants, which were also
9:24pretty small due to the phenomenon of
9:26island dwarfism. Homo floresiansis
9:28thrived by themselves for 100,000 years.
9:31And less than a decade ago, researchers
9:33in the Philippines found yet another
9:35human species, Homolonensis, that also
9:37likely lived around the same time. Like
9:39Homo Floresensis, Luzonensis was tiny.
9:42But unlike any other human species,
9:43there's evidence that Luzonensis became
9:45more aroreal again. Their curved
9:47handbones indicate they spent a bunch of
9:49time in the trees, perhaps gathering
9:50fruit and raiding bird nests. And
9:52finally, at the very same time that
9:54those six other species existed all
9:56around Africa, there were small bands of
9:58homo sapiens, which look pretty much
10:00exactly like modern humans. Over the
10:01next couple hundred thousand years, as
10:03our species spread all over the world,
10:05we became more capable of complex
10:07language and thought, our social
10:08networks grew, allowing us to pass new
10:10skills and tradition down across
10:12generations. And as the rest of the
10:13human species either died off or
10:15interbred with us, homo sapiens became
10:17the last humans in existence and the
10:19only ape that's capable of making a
10:21video and a beautiful poster about apes.
10:23Okay, so about that ape poster. It was
10:26painstakingly drawn in amazing detail by
10:29our wonderful illustrator Homo sapiens
10:31here at Minute Earth, and it would look
10:33fantastic on the wall of your house or
10:34your classroom. To get one, click on the
10:36link in the description. And if you buy
10:38it in a bundle with our dog and cat
10:39taxonomy posters, you'll get 20% off.
