I started writing this blog post whilst sat in a half-deserted village high up in the Gaoligong mountains in China. Occupied by only 10 remaining elders who refused to leave their traditional lives behind, I had the privilege of staying here and immersing myself into daily life.

I am seated by myself as the morning sun blinds me as it peeps out from over the moss-covered tiled roofs. Two chickens are currently sneaking past me into the kitchen to morbidly watch their duck cousin be prepared for breakfast. They scream as my host shoos them away flapping her arms wildly.

The houses date back 50+ years and are made from old wood and bamboo harvested from the forest in the days before the nearby reserve was established. Mules are found on the ground floor of these dwellings with humans roosting above. As a result, night-time can be a very noisy affair!

I also experienced a huge storm at 3 am. I’ve slept through many tropical storms when I lived and worked in Indonesian Borneo, but this was something else. The walls rattled as the rain beat against it and droplets started to seep through and trickle down. I thought the storm would snatch the flimsy roof right off, but I am glad to report that all houses — and mules — were still standing when I woke up.

My PhD is all about understanding local nature and wildlife values, comparing gibbon (small ape) knowledge, and investigating patterns of natural resource use. I have spent the past few months collecting social data in the form of structured interviews and small group discussions with local communities in both Hainan and Yunnan provinces. To get the most candid answers, it is important to immerse yourself into local life.

I have drunk countless cups of green tea and bottles of “bai jiu” (lethal Chinese wine) as a result, been dressed up as a local Hei Lisu person, braved eating the 100-year old egg, and scoffed so many sunflower seeds that I am ready to sprout!

Before embarking on my PhD journey, I was given an antique book by Robert Van Gulik, a Dutchman fascinated by gibbons and their significance in Chinese culture. Published in 1967, “The Gibbon in China” is a magical collection of poems, stories and paintings dating back to 200 BC. Rich in its content, I was overwhelmed with the stories about “lonely”, “sad-looking” yet “magical” apes who sing haunting and melancholy songs in the Chinese mountains.

Taoists (those that believe in ancient nature-worship regarding the flow of “ch’i” energy in all living things) talked about gibbons being superior to humans. Gibbons were often referred to as “gentlemen” as discussed in my previous blog. Everyone loves good manners — bring a gibbon to meet the parents and they won’t be disappointed due to their impeccable “table manners” (unlike their mischievous macaque monkey cousins), according to an 8th-Century poet, Liu Tsung-Yuan. Their intelligence, supposedly similar to humans, is also regularly mentioned, especially when needing to drink water from a nearby river. Forming a chain by holding hands, gibbons would lower themselves down to the river. One should therefore never “…place a gibbon (Yuan-yu) in a barred cage [as] how could he then show his clever skills?” (4th Century statesman, Ch’u-tz’u).

Having read this book from cover to cover, I was pumped to record rich gibbon stories during my field season. I was therefore incredibly shocked and disappointed to learn that many traditional stories have not been passed down through the generations.

China is made up of 56 different ethnic groups, all of which used to be rich in culture and history with traditional dress and sigils (both of which are now rarely seen). I interviewed participants from six of these ethnic groups and asked them questions regarding  the importance of gibbons and forests in their local culture. Participants either didn’t understand the question or they would say there is no connection.

I was relieved to hear that a few elders still have a tale or two to tell, especially when it comes to gibbons being able to predict the weather:

“When gibbons sing, I know it will rain tomorrow.” (Anonymous).

An elder in Hainan province told me about how gibbons came to be which involved a naughty, lazy boy who was scolded with an iron on his butt. He then sprouted hair and turned into a gibbon.

I also had a surprisingly funny interview with a 70-something year old man who used to work in Burma harvesting wood to sell back to the Chinese. He spoke about his love of gibbons…to eat! We spent most of our interview crying with laughter as his opinion was so far from my own. He kept insisting that gibbons were incredibly ugly and thought I was crazy because I felt they had aesthetic value.

“Look at their ugly faces!” He would yell. “Ah, they taste so good! Such a shame the government won’t let me hunt them anymore.”

It is important when I conduct these interviews that I remain impartial. At the end of the day, my PhD is all about finding sustainable solutions for both humans and gibbons alike.

My favourite moment was with an 87-year old woman who heard that a “laowai” (foreigner) was staying in the village. Having never left her village or seen a Caucasian woman before, we had a very special, informal moment bonding over gibbons and discussing what life was like during her youth — and what life was like now.

Although I am still at the start of my PhD journey, I have teamed up with a local non-governmental organisation called Cloud Mountain, who carry out conservation education activities. We hope to work together to reintroduce some of these traditional gibbon stories back into these villages. With only 28 Hainan gibbons, 150 Skywalker Hoolock gibbons and 110 Cao Vit gibbons remaining (my three study species), hopefully we can remind people of their magical, shared history and raise the profile of these forgotten apes before it is too late.

With Halloween now behind us and the golden days of autumn getting shorter and shorter, a new time of year is fast coming upon us…one filled with tissues, stuffy noses, and general misery. Flu season.

Yes, it’s that time again, when the cold frost that heralds winter comes nipping at our toes at night to suck the warmth from our bodies like the vampire that it is. Feverishly we brew our teas, cling to those hankies and wrap ourselves in our best woollies and Jon Snow faux furs in an attempt to fend off illness. Yet we ourselves are guilty of our own vampiric methods in this War of the Wheezing. Our flu shots, and basically most drugs and medical injections today, are possible because we harvest another species’ blood: Horseshoe crab blood.

The horseshoe crab, Limulus Polyphemus, is actually more closely related to scorpions, spiders, and mites than to crabs. Its common name is obvious; its exoskeleton is a large shell shaped like—you guessed it—a horseshoe. These strange-looking creatures have 10 eyes distributed around the shell to help them navigate their way. Don’t be fooled by the tail that looks like a stinger; it serves as a rudder while swimming, and can help the crab reorient itself when it gets flipped over. The horseshoe crab is the only species within its family, Merostomata, which means “legs attached to mouth”. Take a look at the 6 pairs of appendages on its underside, and you’ll see why.

The blood of horseshoe crabs produces limulus amebocyte lysate (LAL), a protein that can detect the presence of endotoxins, bacteria, and other sources of contamination, which we use to render our medicines safe. This protein is found nowhere else on earth. It’s no wonder that this marvellous miracle protein would be found in the blood of horseshoe crabs; they’ve have remained virtually unchanged in the 450 million years they’ve existed. They’re literally living fossils, and yet another example of the strange mysteries of ocean life.

In the 1960s humans discovered the amazing LAL and soon after put it to use in pharmaceutical laboratories around the world. Horseshoe crabs were gathered from their native Atlantic habitats, taken to facilities, drained of up to 40% of their blood, and returned to the ocean. The problem, however, is that this method does little to track what happens to the crabs after they’ve returned to the wild, starved and injured. It is estimated that 50,000 die in the process each year; this, sadly, may be a gross underestimation.

Since the 1850s, Atlantic fishermen have harvested about 1.1-2 million horseshoe crabs annually to use as eel and fish bait. Once the medical industry got involved, however, horseshoe crab populations have drastically reduced, and by 2016 the species was added to the IUCN Red List.

A recent publication in June 2018 claims to have found a synthetic alternative to LAL; if true, this could mean a total turnaround for the species. And, possibly, humans may not have to rely on draining these ocean species’ blood and threaten their existence to protect ours.

I am a primatologist; that is, a scientist who studies the behaviour, abundance and conservation status of monkeys, lemurs and apes. My specialty area and the focus of my PhD research here at University College London, is the plight of the gibbons, the smallest of the apes.

Gibbons are often forgotten in the shadow of their great cousins — the orangutans, chimpanzees, bonobos and gorillas — receiving less funding, as well as research and media attention. This is very unfortunate seeing as 19 of the 20 species are on the brink of extinction. The Hainan gibbon, for example, is the world’s rarest primate with a mere 26 individuals making up their entire global population.

I am always thrilled therefore to see media articles raising some much needed gibbon awareness, even if the news story doesn’t always paint us humans in the best light.

In 2004, one of my supervisors from the Zoological Society of London, stumbled across a gibbon skull inside a tomb in Xi’an, Shaanxi Province, China. The skull is believed to be ca. 2,200-2,300 years old and the potential property of Lady Xia, the grandmother of China’s first emperor, Qin Shihuang, who is famous for his striking terracotta army. Inside this ancient tomb was a whole menagerie of other animal skeletons including a crane, bear and a leopard — yet another example of human-animal relationships that have dated back millennia.

Although this exciting discovery could tell us a lot about our evolutionary shared ancestry with gibbon species, there are still many unanswered questions. We are unsure if the skull, now said to belong to Junzi imperalis (meaning the ‘imperial man of virtue’ due to the strong historical relationship between humans and gibbons in Chinese culture) is in fact a new species and where it came from. There are strong indicators, however, suggesting that this potentially new species of gibbon could be the first ape to have vanished off the face of the earth due to human pressures. Now extinct, we need to look at our current impact on the planet to ensure we don’t do the same with our other cousins.

Part of my PhD research examines the relationship between humans and animals, especially amongst local communities found in gibbon habitat regions. This intrigue, along with my love of mingling with the public, led me to my new role as a Student Engager in the UCL museums. For example, the Ancient Egyptians also had a strong connection with animals which I hope to explore over the coming months in the UCL Petrie Museum, and the Grant Museum of Zoology also has a couple of gibbon skeletons hanging around. Come and see for yourself!

For humans, touch is an important way to gain information about an object. We can tell if something is soft or hard, heavy or light, smooth or rough or fluffy, pliable, sharp, irregular. During my masters class on human dentition, I learned to identify teeth by touch to get around visual biases. We spent a significant amount of time touching objects in our environment, so we tend to get angry when museums tell us not to touch the objects.

I understand the desire to touch a piece of history. There’s a feeling of authenticity you get from holding something made by ancient people, and a sense of disappointment if you’re told the artifact is actually a replica. A British Museum visitor commented that “It was just lovely to know that you could pick something up that was authentic. It was just lovely to put your hands on something.” Another said “You do think sometimes when you’re looking in the cases, sometimes I’d like to pick that up and really look closely.”[i]

Even with “no touching” signs, museum visitors continue to touch things. Sometimes it’s by accident and sometimes they get a sneaky look on their faces, knowing they’re ignoring the signs; most often, they don’t realize what they’re doing is damaging the object.

Passive conservation of an object involves creating a stable environment so that the object can continue its “life” undisturbed. Sudden changes in humidity, temperature, and light can degrade the object. Touching it introduces dirt and oils from your skin onto its surface – the same way you’d leave fingerprints at a crime scene. Additionally, the oils can then attract dirt to linger, and acidic oils can also degrade metallic surfaces.

Yes, museum professionals handle objects for research purposes. However, we attempt to handle them as little as possible with clean hands and wear gloves when appropriate. This difference between museum staff and the public is also one of quantity: it’s ok if one person does it occasionally, but if everyone touches it on every visit, the grime adds up. In 2009, the Ashmolean Museum in Oxford introduced a “touchometer” that counts how many people have touched an object made of various materials. As you can see in the image below, after nearly 8 million touches, the left half of the object is severely degraded. The stone (centre) has developed a patina, the metal (bottom) has become shiny, and the cloth (left) has entirely worn away. (Also, people have scratched the frame.)

If you walk through the British Museum’s gallery of Egyptian statuary, you can clearly see the areas on artifacts that people like to touch – the corners and public-facing edges of sarcophaguses are darker than the wall-facing edges, and anything round and protruding tends to have a sheen that takes years of painstaking work to remove (hands, feet, and breasts of statues at human height are particularly vulnerable).

The Grant Museum has specific objects that can be handled, and UCL Museums have object-based learning programs to introduce students and specific groups to handling museum objects. [ii] Many other museums have touch tables or touch sessions where you can feel the weight of hand axes or porcupine quills. Don’t despair if you’re asked not to touch something in a museum – we’re not angry, we just want to make sure they’re preserved for future museum visitors to enjoy.
