Primate family tree main and great and lesser apes

Primate family tree

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. 

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 Apes

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.

For more information on each species, click on their photo and this will take you to their page

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

Borneon Orangutan

Orangutans are often animals high on the list that people wish to see one day. Orangutans are the only great ape that live outside Africa. While fossils show that at one time it was found on the mainland of Asia, the Orangutan is now restricted to the islands of Borneo and Sumbatra.

This page is devoted to the Orangutan on the island of Borneo. The Borneon Orangutan currently numbers roughly 104,750 wild members, which is far more than the other subspecies. It is classed as endangered – 50% of its rainforest has been cut down.

As always, we hope to add many destinations for Orangutans in the near future, do get in touch if you wish to list somewhere in their range. Below, any listings that might get added in the future, you will find all the articles we have written on Orangutans

Bonobo

Bonobo

Bonobos are a species of great ape, that split from chimpanzees between 1 million and 2 million years ago.

While for some people this is not that long ago, and Chimpanzees and Bonobos look so similar, their behaviour is significantly different. So what makes it so clear that these animals are separate species? Well they behave in totally different ways.

Where as male dominated chimpanzee society can be incredibly violent, and one of the first things that young chimpanzees learn is to get out of the way of the fighting as fast as possible;  Bonobo society is incredibly relaxed. Bonobos have found that the most simple way to deal with stress in through sex. Bonobos have a great deal of sex, and it occurs between all different couplings of members of the group. Female Bonobos are also the dominant ones .

They live on the other side of the Congo river. Indeed, it it thought that it was the Congo river forming which split these two species, and ended interbreeding 

There is one huge national park that protects these animals – Salonga national park, which has an area of almost twice the size of Wales. There is also Lomami National park which covers 3500 square miles.

Alongside this national park there are a handful of reserves including Tumba Ledima Reserve, Sankuru nature reserve, Kokolopori Bonobo Reserve. As well as many more.

We hope to link to as many of these as possible over time, though currently we don’t have any. As we get these we will add them at the bottom of the page. Directly below this, is a documentary on the bonobo, and below that is a list of all articles that have been written on this website about these fascinating animals. As we make links, these will be added below both of these.

Gorilla

Gorilla

For anyone who has watched the scene from Life on Earth – where David Attenborough sits down with Mountain gorillas, the gorilla needs no introduction. Now of course if you go on a trek, you are unlikely to get quite so close (though you never know, the Gorillas have a mind of their own). 

What is important, is that if gorilla trekking took off across Africa, then every population of Gorillas would become very valuable. The problem is that through the process of habituation the gorillas loose their fear of humans – it is totally unfair to undertake this process anywhere where the Gorillas might need their fear of humans to avoid poachers – and this still covers way to much of the world.

Below the video, I take each subspecies of Gorilla in turn and discuss how it is doing. Below this, I will try to list places that you can visit the Gorilas. Currently we only have one place on the list, but I hope for this to grow into a complete list, to aid in your future gorilla trekking adventures. If anyone runs a lodge (or knows someone who does) please do get in touch using the List your wild place option at the top of the page.

The cross River gorilla is a critically endangered subspecies of the Western lowland gorilla species. The cross River gorilla are scattered in at least 11 groups across the lowland montane forests and rainforests of Cameroon and Nigeria, an area of 3,000 square miles, or a little smaller than Puerto Rico. There are only 200-300 that remain of this subspecies. While there are some physical traits that are different between these species, the cross River gorilla has become a Highland specialist. Although known to have interbred in the past, genetic analysis suggests this stopped more than 400 years ago. Changes in climate may well have been the catalyst to stop the interbreeding.

 

In this way, the cross River gorillas and the mountain gorillas have similar habits and ecosystem niches. In this way, it could be suggested that cross River gorillas are simply 50 years behind mountain gorillas in the sense that 40 years ago, there were only around 250 mountain gorillas – this population has increased to over 1000, so clearly it isn’t too late for the cross River gorillas numbers to recover. Could a similar recovery take place? Perhaps following the pattern set up by Diane Fossey for tourism of the mountain gorillas, might work?

 

Western lowland gorillas have a wild population in a fast healthier position, with an estimated 100,000 remaining. Unfortunately though, this is a very tough estimate as they live in some of the hardest to reach jungles so an accurate count is hard. It is however, thought that this gorilla population has seen a 60% reduction over the last 10-25 years. It is thought that if the pressures of placing and diseases were removed this population would recover in about 75 years (of course these pressures are unlikely to disappear, and with the loss of rainforest there may be nowhere for these gorillas to live if they did recover.

 

Eastern lowland gorillas are in a fast worse state than their Western counterparts – it is thought that only 5000 remain. It is only found deep in the democratic Republic of the Congo. This subspecies has face precipitous declines and is therefore considered critically endangered.

 

Mountain gorillas are only found in two reserves, however due to their plates being highlighted by dian fossey, the population spread between these two reserves as clients from around 300 in 1960 to 800-1000 today. There are no mountain gorillas in captivity.

 

It is unfortunate that there is little positive news on either of these species at the current time, but many people are working on it. However what is clear, is that with all four subspecies of gorilla are threatened with extinction – largely as a result of habitat loss and sweetheart down the African rainforest.

 

At the moment our only links are to these two luxurious places to stay on a private reserve bordering the Virunga national park. We hope to add many more over time

Kataza house is the perfect place for a large family to stay. There is much to do, and people to look after children while adults go gorilla trekking
Kitondwa lodge is a place for small groups or individuals to stay during their trek. As a smll lodge your experience works around your likes and dislikes

Chimpanzee

Chimpanzee

Given the incredible and very obvious similarities between humans and Chimpanzees, it is perhaps not surprising that seeing them in the wild is a wish for many people. Unfortunately, many fail to turn this wish into reality, for a variety of reasons. You cannot visit the Chimpanzees in a car, as the forest is too thick, so trekking is the way to go. Chimpanzee trekking is an incredibly exciting thing to do. Currently almost all of the chimp trekking takes place in just one or two of the places that they live wild.

If it is possible to change this, we can make chimpanzee populations across the tropical African belt valuable to local people, and therefore protect their long-term viability. The wild chimpanzee is an essential part of the places that they inhabit, so hunting and poaching threatens the collapse of the entire ecosystem.

Most of the places that they inhabit have already been invaded or lie close to human habitation so hunting and poaching threatens the collapse of the entire ecosystem One of our closest relatives and an image that we are very used to, unfortunately the chimpanzee like all other great apes is facing a precipitous decline in its population. Subspecies include, 

Eastern(21000-55000), 

Western(35000), 

Central(115000) and 

Nigerian-Cameron (3500-9000). 

As you can see many of these have wide ranging estimates which shows how little idea we have at the current time.

 

Chimpanzees inhabited wide-range of forests and open woodlands. When not attacked by humans, and when their homes are left standing they can do very well.

 

It is possible that organised tourism amongst some of these populations could help save them. Unfortunately it is entirely possible that many of these populations are lost before we can help. We aim to link to as many place that you can visit. These will be linked within a page for each subspecies, though some will also be linked at the bottom of the this page.

We will also have a list of all articles on chimpanzee from this website below
