Bonobos and Chimpanzees are thought to be our closest relatives, and when you watch this young bonobo play with water. Knowing this, it is perhaps not strange that researchers are finding that bonobos combine words in ways that sound very human. They are able to combine several sounds, to create a phrase, with more meaning than its individual parts.
This is something that was considered unique to human language. A simple example of this ability would be something like “brunette painter” is something that many animals can do – it is a person which is both brunette and a painter – however bonobos can combine them is such a way like a “good painter”, good is not another description, but instead changes the meaning of painter- the two words give more meaning together.
I have tried to write on Bonobos, relatively regularly on this website. This is for a variety of reasons. Being the last species of unique great ape to be found (species like the Tapanuli Orangutan have been discovered since, but the bonobo is far more distinct. Bonobos are female dominated society, and it is a far more peaceful society than with chimpanzee. Violence is rare, with bonobos using sex to deal with tension and conflict instead.
They did a great deal of analysis, recording hundreds of vocalisations. They identified 7 different calls, used in 19 different combinations and found that of these 4 followed the rules of human sentences (the other 15 have not been properly analysed as yet.
One example, was where Yelps are thought to mean “lets do that” while grunts are thought to mean “look at what I am doing” but when combined into a yelp-grunt it appeared to mean lets do what I am doing – and was often used to encourage other members of the group to build their night nests.
Bonobo are still loosing territory in the wild, and with their whole range restricted to just the Democratic republic of Congo, their population is far more fragile than many other great apes.
Visiting the Bonobos will give the country more reason to preserve them.
Even before the study was started, it was known that some species are not male dominated. Above is a family of Bonobos, and these great apes live in a female dominated society.
Given our assumption that on male dominance, it is perhaps surprising, that only 58% of primate species have dominant males. Perhaps not surprising, as a result, every major primate group had at least one species which was female (or co-dominant) structures.
Indeed, with the gibbons (or lesser apes on this website, to check them out, click here to visit the home page, and then expand the species database, and click on lesser apes) all 5 species examined (there are a total of 20) have been classed as non-male dominant.
Amongst primates, this likelihood is (according to Lewis, the head of the study) relatively easily predicted, as tends to occur in the species, where there is little difference between the size of male and female members.
An example here, is clear: while a male gorilla can weigh twice that of a female, siamang gibbons only have males a couple of kg heavier than females – not surprisingly, while male gorillas are dominant, this is not the case with siamang gibbons.
It should be noted, therefore, that while 4 out the 5 species of great apes are male dominated (we assume this in humans as well, though, in the modern day, it would be hard to argue that we are not more of a co dominant species. Given that likely all the lesser apes (the gibbons) are more or less co-dominant, it follows, that even just looking at the apes, more are female dominant or co-dominant.

The problem with stopping deforestation, is that for the majority of the world we are far removed from rainforests (from where I sit in the UK, I would have to travel 3250km (over 2000 miles) to the nearest rainforest, which is an area on mainland India). Indeed, rainforest is generally something that only survives in developing countries.
This means that, for most people, they either live far removed from the rainforest, and so cant see it impacting them, or they live near a rainforest, but are struggling to provide for their family and those around them. It is quite true that many people in both the first and third world would like the rainforest to survive – indeed, should you talk to people in the west, many are very worried about the survival of the great apes, who are rapidly loosing land.
The problem is simple. Those living in the third world are living hand to mouth, so unless they work in tourism, the rainforest is often an inconvenience that makes life harder.
In 2023 a total of 6.4 hectares of forest were destroyed – more than 25,000 square miles. However, more concerning is the fact that 62.6 million hectares of forest (almost quarter of a million square miles) was degraded – for road building, logging, and forest fires. Degraded land is often less good for carbon storage, as well as conservation of the worlds wild species. It is often, then not long, before someone comes along a removes the rest of the plants so that the land can be used for something else.
And what was this deforestation for (other than logs)? Beef, soy, palm oil paper and nickel.
The Brazilian Amazon is one of the bright spots, where since the election of Luiz Inacio Lula da Silva, deforestation has fallen 62%. Unfortunately, in the same time period, Indonesia’s deforestation is up 57%
It seems hard to see how the world will meet its goal of cutting deforestation to zero by 2030 as most countries have pledged. Also, despite reductions in deforestation, the Amazon has had one of the hardest years in terms of forest fires – something that only gets more likely as rainforests are lost, and climate change increases the temperature in many parts of the world. It is a sad fact, that there is often not a great deal of temperature difference between a rainforest which is functioning, and one that dries out and becomes a fire hazard.
Having said all this… a study in Indonesia has found that controlled low-intensity logging doesn’t have to negatively impact a forest in terms of carbon storage or food availability – this in turn means that much wildlife can survive.
The problem often is that if the land is in private hands, then low- intensity logging is not going to happen. If the landowner has decided to deforest, they will raze the land. In national parks, in theory low intensive logging would be possible, but this would require people to control the logging, and this is the issue that we have in the first place. Unfortunately, despite the pledge by 140 countries, deforestation is coming back.
In a related subject, the Indonesian president Prabowo Subianto has stated that palm oil expansion won’t deforest because palm oil has leaves. There are many issues with this, but perhaps primarily amongst them, when forests are cut down, they are usually replaced with grass lands for grazing cattle – these are also covered in leaves. This is obviously stupid – it may well be a better thing, that the rainforest is going to be replaced with plantations, but it has been shown that palm oil plantations take up a tiny proportion of the carbon that rainforests take up.
In another article, there was a finding that macaques living in palm oil plantations have an alarming infant mortality. Unfortunately, these macaques are not unique in being threatened by palm oil, but others include orangutans, elephants, tigers, pangolins, bonobos, and Irrawaddy dolphins.
While palm oil may be a better vegetable oil than other crops, it still looks like it will lead to us loosing most of our rainforests, unless a grip on this is found.
A female orangutan, who had failed to bond with either of her first two offspring (and as a result had both died), found 30 volunteer human mothers, to come in to breastfeed their babies in front of the orangutan.
The exhibit was shut, so that the mothers could breastfeed topless – allowing Mujur the 19 year old mother to be, to see what was happening. As can be seen from the image, the orangutan showed a great deal of interest in the breastfeeding – and as well, Mujur was shown videos of orangutans feeding their babies.
The primates are in some ways one of the most successful families. It is true that many are now endangered, however, unfortunately, that is as a result of the run-away success of the most successful member of the primate family us! Having left the rainforests behind, we have been reducing their coverage dramatically over the last few centuries.Â
The sad thing, is that while we have pushed many of our closest cousins towards extinction, the loss of forests may well cost us dearly in the future as well. As a species, we need to pull together to meet this challenge. in order to jump to the various families, click on the family of interest above – though all can also be reached by scrolling down.
Great ape Family split is thought to have split from its nearest relative – the gibbon family, around 17 million years ago.
4 million years later the Orangutan family split from the gorilla line and the human/chimp line.
3 million years after this (so around 10 million years ago) the gorilla family split from the Homo (humans) and Pan
Finally the human line (homo) split from the Pan line 5-6 million years ago.
It should be noted, that chimpanzees and Bonobos split from a common ancestor just 1.8 million years ago. This occurred as the two populations ceased to be able to have contact with each other – the Congo rive formed between 1.5 and 2 million years ago.

It should be noted that while I have grouped eastern western and skywalker gibbon together, there is some contention that the skywalker gibbon should be in its own genus, having diverged around half a million years aog
The mountain gorilla is a sub-species of the Eastern Lowland gorilla. It is isolated on two sets of mountains, they are only a few hundred miles apart, but given the space between their populations is one of the most dense human habitation in Africa, reconnecting these habitats will not be possible in the near future.
Mountain gorillas are very similar to eastern lowland gorillas, though as they have 8 inch hair all over their body, they look far larger.
Currently, there are 1063 mountain gorillas in the wild, split between their two reserves. This does not sound high, but has doubled since the 1980s when each reserve only had around 250 individuals. They are nowhere close to fully recovering, but it is questionable whether their two homes can support more gorillas than currently live there.
The Eastern Gorilla, or Eastern lowland gorilla (as the Eastern gorilla subspecies is the mountain gorilla) is a species which makes its home only in lowland tropical rainforests in the eastern DRC. In the last 50 years, its range has almost halved, from 8,100 square miles—about the size of the state of Massachusetts— to about 4,600 square miles today. This subspecies may now occupy only 13% of its historical range.
There are only about 5000 Eastern lowland gorillas left in the wild. While much of their numbers decrease over the last 50 years, has been as a result of a loss of habitat, their most immediate threat is currently, is that of the bushmeat trade. The area around their range is home to people with very little money. Tourism to this area, would likely greatly improve this issue and reduce the demand for Gorilla bush meat. Apart from the threat for the continued survival of this giant (alongside the mountain gorilla, this species is the largest great ape still living.

As can be expected, its range is very small, though it is hard to know if it ever had a far larger range. Its range is the small dot of light brown found on the map above the pink area.

The western gorilla is thought to number around 316,000 in the wild. However, this species is actually made up of two subspecies.
Most are simply known as the western lowland gorilla.
The other subspecies is the cross river gorilla, this only has around 200-300 members remaining in the wild. Click here to view the cross river gorilla page. You can see that their population only inhabits a small area.
Any links we get that will allow you to watch lowland gorillas will appear below the news section.
Human beings are part of this family tree. Whatever your position on creation/evolution it is undeniable that our genetics are closely related to the great apes. I am a Christina, however the genetics are clear – This should not cause a problem with a belief in creationism, but it is a fact, either way.
We are a fascinating species, but it is beyond the scope of this website.
