“The stability of nature can no longer be taken for granted”

It came like light out of the walls

evolve  | ɪˈvɒlv | 
verb 
1 develop gradually
• (with reference to an organism or biological feature) develop over successive generations as a result of natural selection: [no object] : Pink salmon are evolving in response to climate change in Auke Creek, Alaska, which is heating up .03 degrees Celsius (.054 degrees Fahrenheit) per year.[i]

origin
early 17th century (in the general sense ‘make more complex, develop’): from Latin evolvere, from e- (variant of ex-) ‘out of’ + volvere ‘to roll’.


Things evolve, it’s what they do. True to the word’s Latin origin, they roll.

As such, our 15-metre wall collage, Ripples in the Open, exhibited at ArtSpace Realm, Victoria (2018–2019) in one ‘finished’ guise, has grown into It came like light out of the walls[ii], a series of collaged drawings for West Gallery Thebarton, South Australia. Unstuck from the wall, rolled, and kept, the landscape within Ripples in the Open has become a new work. We have cut into the salvaged pieces, reused and adapted elements to make use of what we had, changed previous reading in the process, and continued a pattern. Images are our narrative, and nothing is fixed.

As we worked, we thought about changes that are small and particular to us. And we thought about changes that are larger, and seemingly beyond our own control. Universal shifts, their very inevitability. That global pattern! Change — insert the common expression — is the only certainty.

The large collaged drawings we have created from the very fabric of Ripples in the Open are a continuation, an evolution of an idea for us, personally. We are organisms working to maintain our own ‘adaptedness’. And, in a broader sense, the animals within the landscape of our drawings signify that “animals can react to climate change in only three ways: They can move, adapt or die”.[iii]

With our planet on the verge of another major extinction event[iv], the question is “whether plants and animals can adapt quickly enough to outpace climate change. We often think of evolution as something that happens slowly, but that’s not always the case. If the selection pressures are strong enough, evolution can happen over mere decades”.[v]

We now have “several examples [of] where organisms have evolved in response to selection pressures associated with climate change, including changes in the timing of life history events and in the ability to tolerate abiotic and biotic stresses arising from climate change. There are concerns that the rates of environmental changes are too fast to allow many, especially large and long-lived, organisms to maintain adaptedness…. Hence, widespread maladaptation and extinctions are expected”.[vi]

We need to preserve marine and land-based ecosystems; increase the connection between natural areas to secure the migration routes that allow for species to travel to cooler zones, and enable the congregation of larger populations needed to support genetic diversity required for phenotypic plasticity and adaptive evolution. This is what we have shoehorned into our series It came like light out of the walls, our functioning (or not) ecosystem on the page.

That organisms are not static is our light (within our drawings).

“For the first time in our history, the stability of nature can no longer be taken for granted. All across our planet, crucial connections are being disrupted, the stability that we and all life relies upon is being lost. What we do in the next 20 years will determine the future for all life on Earth…. Earth’s most important habitats, and …. the life they still support …. must be preserved if we are to ensure a future where humans and nature can thrive.”

Notes:
[i] “The salmon are now migrating out of the creek earlier, and scientists have shown that that change is genetic. Wild thyme (Thymus vulgaris) in France has evolved in response to fewer extreme cold events since the 1970s, producing more pungent oils to deter herbivores (at the cost of becoming less cold-hardy). Tawny owls (Strix aluco) can be light gray or brown, depending on the genes they inherit from their parents. As snow cover in Finland has declined since the late 1970s, the light gray owls, best camouflaged during snow, no longer have much of an advantage, and scientists have shown that brown owls are now much more common.”
