A phylogenetic is a part of evolutionary biology and systematize the inference of the evolutionary history and relationships among groups of organism and species. Often visualized as a branching diagram, the phylogenetic tree shows the evolutionary relationships among various biological species.
The 300-kilo molecule, similar to Bigert & Bergström’s earlier work, CO2 LOCK-IN (2011- ongoing), represents an average Swede’s CO2 emission over two weeks. Together they symbolize man’s relation with the greenhouse gas: When she climbs up the evolutionary tree, the amount of CO2 increases in the atmosphere. Is she able to find equilibrium, or is it impossible for her to find balance with nature?
The increasing CO2 emissions are the main reason for the extreme weather and temperature rises we witness today, caused by climate change. Scientists have warned that the amount of CO2 in the atmosphere should never rise above 400 PPM, a level we have now passed. In fact, from a geological time perspective, we have not seen numbers like these during the last 3 million years. The last time the amount was this high temperature was 2-3 Celsius higher, and the sea levels were 15-25 meters higher than today (NOAA).
At the same time, coal and carbon dioxide have been crucial for the origin of biological life. For humankind, we can witness how emissions have increased simultaneously with every step up the evolutionary tree. The fragile balance between the dancers reflects the need for communication and solidarity between human people. When equilibrium succeeds, the kinetic sculpture spin around its axis without any external force. If a dancer moves without a reaction from her counterpart, the balance interrupts, and the movement ceases.

A "glory or a paradise" were the renaissance remake of Greek machines used in the finale of a spectacular scene. These were cloud formations carrying performers in flying chairs, all maneuvered by stage workers behind the scenes using hand cranked drums and ropes. The images show the scene machinery without and with the décor.
