Knuckle Walking

Wild Chimp Knuckle Walking


13 and 1

Chimps have two arms and two legs, yet unlike us, they tend to prefer walking on all fours, making them quadrupedal. Just like us, they have opposable thumbs which they also have on their feet too, known as opposable toes (handy!) To help with walking on all fours, their arms and legs are the same lengths. They bend their long fingers under and walk on their knuckles, yet walk on the sole of their foot. Walking like this makes it easier to climb trees and carry around small it's of food in their knuckles as they wander about.

There are many theories about the evolution of knuckle-walking. Some argue that it originated from fist walking seen in orangutans which adapted for a more terrestrial life, rather than one predominantly in the trees. Others suggest that they may have come from a bipedal ancestor which explains why they also walk bipedally on occasion. Whatever the truth, chimpanzees have adapted to their life on their knuckles very well.

​Based off real animals that Gillie and Marc met while studying, the public will be able to meet individual animals. This will help them to realise that there are apes with unique personalities, thoughts and emotions. The loss of one individual is just as devastating as losing an individual human.

With public art, more people will come into contact with these sculptures, will stop and consider them, will take a photograph, and will discuss this with their friends and family. Through this increased exposure, the message of love, family, and conservation will be spread much further than any piece of art in a gallery ever could. It will bring people into close contact and will help them to fall in love. With love comes a greater urge to want to create a change and save the great apes.

​The sculpture will be aligned with the hashtags #LoveTheLast and #ChimpsAreFamily to raise unparalleled awareness about the sculpture’s cause across the globe.

To help protect the great apes you can adopt a chimp and help them via the WWF:


VELUX Group will become Lifetime Carbon Neutral by 2041

VELUX Group is the first company in the construction industry to take responsibility for both past and future carbon emissions. The global roof window manufacturer will capture its historical carbon footprint (scope 1 and 2 carbon emissions)  – dating back to its founding in 1941 and through to 2041 – through forest conservation projects, identified and managed by Worldwide Fund for Nature (WWF). It will also reduce future carbon emissions from its operations (scope 1 and 2) and value chain (scope 3) in line with climate science (the 1.5 degree Celsius target for global warming). By combining these two sustainability goals, VELUX Group will become Lifetime Carbon Neutral by its 100-year anniversary in 2041. The Lifetime Carbon Neutral commitment was initiated by VELUX Group and developed in collaboration with WWF and the methodology was verified by the Carbon Trust.
