Origin brings two opposing material processes into a single reflection on evolution. Vhils excavates Charles Darwin's portrait from the wall, while Bordalo II constructs the adjoining chimpanzee from discarded plastics, rubber and other urban residues. Their first mural together, created for Cor de Chelas in Lisbon (2024), does not simply combine two recognisable practices: it sets removal against accumulation, geological depth against contemporary excess. The reference to Darwin places this material encounter within a longer history of adaptation and interdependence, while the chimpanzee unsettles the distance through which humanity defines itself against other species. Here, the wall becomes a shared field in which biological evolution and the environmental consequences of human production are held in direct tension.
