Primate family tree main and great and lesser apes

Primate family tree

Great apes
Lesser apes
Old world monkeys
Lemurs
New world monkeys
Lorisidae & allies
Tarsiaforms

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 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

Gibbons

siamang gibbon genus Symphalangus
hookock gibbon (Eastern, Western and Skywalker) Genus Hoolock
genus Normascus (crested gibbon)
Genus Hylobates (dward gibbons) Agile gibbon

Genus Nomascus

This family is the Genus: Nomascus or crested gibbon.

The last Genus of gibbons is Hylobates: dwarf gibbons.

Mountain Gorilla

Mountain Gorilla

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.

Eastern Gorilla

The Eastern gorilla (lowland)

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.

Eastern Lowland gorilla

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.

Any news articles will appear below, and links to allow travel to this region will be added below.

Cross-river gorilla

Cross-river Gorilla

Cross river gorilla

Cross-river gorillas were originally discovered in 1904, however, in the decates that followed, it was thought that this animal had been hunted to extinction. It was rediscovered in the 1980s, but is incredibly endangered, with only 250-300 remaining. It should be noted, that this is considered a sub-species not a species in its own right – though it is still of great interest, and saving the few that still survive should be a high priority.

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.

As we make connections, these will be added below – to help you arrange your travel to see this rare animal

Western Gorillas

Western lowland gorilla

Western lowland gorilla on nature background

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

Human beings

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.

Tapunali Orangutan

Tapanuli Orangutan

Tapanuli orangutan

Orangutans are often animals high on the list that people wish to see one day. Orangutans are the only great ape that lives 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 Sumatra. There are 3 species of Orangutan and their conservation status varies dramatically. The Orangutan was first scientifically described in 1779 by Dutch anatomist Petrus Camper. 

The Tapanuli orangutan, was discovered in 2017, It lives in the Tapanuli forest in Sumatra, but is thought to be more closely related to the Borneo Orangutan. It is thought that just 800 remain, in an area covering around 1000 square miles. This is around 9.75% less than the area they would have historically roamed. It is scary when we are only discovering species of this importance when they are this close to extinction. One would think that they Indonesian government would be working as hard as possible to save what habitat remains, but there is a dam being built, which will split this population into 3, and it is quite plausible that they will not survive.

You will find all the articles we have written on the Tapanuli Orangutans below (there will be a video between)

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. These links will be added below the news sections as we make links.

Sumatran Orangutan

Sumatran Orangutan

Sumatran Orangutan

 Orangutans are often animals high on the list that people wish to see one day. Orangutans are the only great ape that lives 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 Sumatra. The Orangutan was first scientifically described in 1779 by Dutch anatomist Petrus Camper. This page is devoted to the Orangutans of Sumatra.

As with all great apes, the Orangutan is a keystone species and by saving its habitat, we save many thousands more as a by-product. The greatest threat has been palm oil plantations – while in theory these are created to reduce carbon emissions, it is questionable as to whether these plantations could ever be carbon negative. Building it on land that has to be cleared of rainforest, means that these palm oil plantations will have huge carbon footprints, which are likely to take over a century to pay off. As such it is not useful for climate change mitigation.
The orangutans of Sumatra are classed as critically endangered. 

They are currently thought to number around 14,000. 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. 

The Borneo and Sumatran Orangutans were only recognized as separate species in 1996

The Grauers Gorilla population is twice as big as thought! Out of the woods? Not so fast

The Grauers gorilla, also known as the Eastern lowland gorilla (confusingly often found in the mountains, just not exclusively as the mountain gorilla is) is a close relative of the mountain gorilla.

Grauer Gorilla: less endangered than thought but still close to extinction
