Active Debate: Relationship to Modern Apes
Gigantopithecus belongs to the Hominidae family, but its precise evolutionary relationship to modern great apes and humans is unclear. Some researchers have suggested it may be closely related to Orangutans (Sundapithecus), while others consider it a distinct lineage that went extinct without living descendants. No DNA has been successfully extracted from Gigantopithecus specimens — ancient DNA retrieval has failed so far — so molecular-level relationship studies remain impossible with current methods.
What We Still Don’t Know About Gigantopithecus
- Complete skeleton: No postcranial skeleton has been found. Body shape, height, and limb proportions are entirely unknown.
- DNA and genetics: All attempts to extract ancient DNA have failed. Its evolutionary relationships remain based on dental morphology only.
- Body size: Height and weight are unknown since no postcranial bones have been found. Estimates range from 2-3 meters tall based on jaw scaling.
- Locomotion: Whether it walked on four legs or was bipedal is unknown — possibly knuckle-walker like orangutans.
- Color and fur: Completely unknown.
- Social behavior: No evidence of group structure, communication, or intelligence level.
- Extinction timing: While most specimens date to ~1 MYA, the latest specimens (Vietnam) suggest survival until ~300,000 years ago.

Is Gigantopithecus still alive�
       The chances are that a lot of people reading this article found it either from a link from another website or doing a web search about the yeti,†‬bigfoot or sasquatch and it’s supposed connection with Gigantopithecus in cryptozoology.†‬
Well this connection is very controversial and most,†‬palaeontologists,†‬anthropologists,†‬primatologists and even many Bigfoot researchers consider it unlikely to impossible.†‬
Supporters of the idea began to make the connection not long after Gigantopithecus was described but first a little history upon just what these other creatures are supposed to be.
       Across Asia and North America there are many stories about giant apes that are described either as human-like apes or ape-like humans that are much bigger than people are today with heights being estimated to be anything from around two to two and a half meters,†‬or bigger depending upon the witness.†‬
These creatures occasionally feature in folk stories passed down from generation to generation and the creatures in them have almost as many names as there are variations of the stories from Yeti to Bigfoot to sasquatch to grassman,†‬the list goes on.†‬
Many of these stories are now in the public consciousness and today there have been countless sightings by eyewitnesses,†‬photographs and plaster casts of footprints,†‬possible hair samples,†‬sound recordings to most famous of all the Patterson-Gimlin film that supposedly shows a Bigfoot walking away from a video camera.
       The problem with the above body of evidence is that it is not enough to convince ardent sceptics.†‬Eyewitnesses will sometimes be accused of misidentifying something else or rather more unkindly just making things up.â€
‬Footprints and sound recordings also get labelled as being fake or misidentified because no one was around to see who or what made them.†‬
Hair samples are usually deemed inconclusive as well and the Patterson-Gimlin film is usually accused of being a guy in a suit because the creature walks like a man and not an ape.
       Because this body of evidence cannot conclusively prove one way or the other that bigfoot-like creatures are wandering around,†‬some researchers have tried to ground the stories in scientific fact.â€
‬Apes are an obvious choice because they are supposedly the most bigfoot-like creatures that are known without doubt to exist.â€
‬The main problem is that they are much smaller than the creatures of legend,†‬but when Gigantopithecus entered the science of palaeontology many researchers immediately started talking about how there was now fossil evidence to prove that Bigfoots existed.†‬
As you can probably already appreciate this is a very reckless way of proving the existence of a creature and when you evaluate the Gigantopithecus fossil evidence and combine that with Bigfoot folklore the two just don’t go together.
       Back in the†‬1950â€â€™â€¬s theories started to be pieced together that stories of Yeti and Bigfoots were actually descriptions of encounters with relict populations of Gigantopithecus that had survived by isolation from the changing world around them.â€
‬Although not given much serious thought at the time,†‬some quite well known anthropologists such as Carleton Coon and Grover Krantz†(‬previously mentioned aboveâ€) ‬began to push their minds to finding form to the idea.†‬
Krantz in particular is known for dedicating†‬a lot of serious study to proving the existence of Bigfoot,†‬even though initially he was sceptical of claims and evidence.†‬
Krantz proposed that Gigantopithecus had crossed over Beringia†(‬also known as the Bering Land Bridgeâ€) ‬from upper Asia into North America.†‬
Krantz also tried to formerly assign Bigfoot to Gigantopithecus blacki in†‬1985†‬but was rejected by the ICZN†(‬the body that governs the naming of animalsâ€) ‬on the grounds that there were no Bigfoot body parts that could be attributed to the existing G.†‬blacki remains.â€
‬Krantz later tried again but this time calling it a new species,†‘‬Gigantopithecus canadensis‒ (‬from Canadaâ€)‬,†‬but again this was rejected because the plaster casts that he was trying to have treated as holotypes were not considered credible.†‬
As already mentioned above,†‬Krantz was an early proponent of Gigantopithecus being bipedal,†‬but the reasoning behind this was discredited on the basis that the jaw features alone are not a distinguishable enough feature to conclude that Gigantopithecus was a purely bipedal animal.
       This is†‬the†‬most obvious problem of the Gigantopithecus-bigfoot connection theory because Bigfoot is supposed to be a bipedal creature with feet similar to a human†(‬but of course a lot biggerâ€) ‬as well as a walking gait similar to a human.â€
‬The great apes however have very different feet with elongated opposable big toes that help them to hold things with their feet.†‬
Also while they can and sometimes do walk on two legs,†‬their preferred mode of locomotion is to walk on all fours.â€
‬Supporters of a Bigfoot lineage often say that you cannot claim that Gigantopithecus was not bipedal because the feet have never been discovered.â€
‬By this very logic however you cannot say that it was either,†‬but additional support against it comes from other known parts.†‬
As mentioned above,†‬the lower jaw of Gigantopithecus is very similar to that of an orangutan to the point that it is classed within the same great ape family.†‬
This means that it is much more likely that Gigantopithecus had the same kind of grasping feet as an orangutan rather than human-like feet.†‬
Not only would this make footprints different to what have been called Bigfoot prints,†‬these feet are not that very well adapted for supporting the body of a creature during bipedal walking,†‬an important part of the reason why great apes will most often walk on all fours.
       Another argument against a Gigantopithecus-bigfoot lineage is the huge gap in the fossil record that marks the most recent Gigantopithecus fossils and the present day.†‬
Some supporters of the theory have made claims varying from no one has bothered to look for Gigantopithecus in other areas like North America to even Gigantopithecus being discovered but hidden away by palaeontologists so that they don’t have to change their theories.†‬
To begin with the first matter,†‬palaeontologists cannot find fossils on demand,†‬discovering a fossil is unfortunately not that convenient.†‬The best that palaeontologists can do when looking for a certain kind of animal is to look for a deposit that ticks the right boxes.†‬
For example,†‬if you want to search for Triassic age ichthyosaurs you would first need to identify Triassic age rocks that were formed from a marine environment†(‬Shasta County of California,†‬USA springs to mind hereâ€)‬.†‬
This does not guarantee a discovery,†‬but it does maximise your chances for finding something along the lines that you are looking for.
       For Gigantopithecus you would need Miocene to Pleistocene age formations,†‬from areas that had dense growths of bamboo during these times.†‬
These deposits are well known from south East Asia where Gigantopithecus fossils are currently only known from,†‬but North America has different deposits.â€
‬These deposits are still Miocene to Pleistocene in age,†‬but the habitats are more like grassy plains instead of the bamboo forests of Asia.†‬
For the sake of argument,†‬a Gigantopithecus would have to radically adapt in form and behaviour to move into this new environment to the point where it would not be a Gigantopithecus anymore.â€
       The idea that palaeontologists deliberately hide fossils to protect their teaching is basically laughable.â€
‬Theories in palaeontology are changing all the time with new discoveries and ideas that were standard teaching a few decades ago†‬already†‬being†‬challenged by new discoveries today.â€
‬Also a palaeontologist that discovered confirmed Bigfoot remains would receive instant fame and recognition for the discovery,†‬so nobody has any reason to hide anything.
       It is the likelihood that Gigantopithecus was almost certainly a great ape similar to a large orangutan that leads sceptics and many Bigfoot enthusiasts to the conclusion that Gigantopithecus is not the mysterious Bigfoot,†‬Yeti or whatever from legend.†‬
Should a Bigfoot ever actually be found however and the eyewitness reports and footprints†‬have all†‬been†‬correct,†‬then we’ll probably find that the creature is no more related to Gigantopithecus than what humans are.
