New research maps 14 potential evolutionary dead ends for humanity and ways to avoid them

For the first time, scientists have used the concept of evolutionary traps on human societies at large. They find that humankind risks getting stuck in 14 evolutionary dead ends, ranging from global climate tipping points to misaligned artificial intelligence, chemical pollution, and accelerating infectious diseases.

The evolution of humankind has been an extraordinary success story. But the Anthropocene—the proposed geological epoch shaped by us humans—is showing more and more cracks. Multiple global crises, such as the COVID-19 pandemic, climate change, food insecurity, financial crises, and conflicts have started to occur simultaneously in something which scientists refer to as a polycrisis.

"Humans are incredibly creative as a species. We are able to innovate and adapt to many circumstances and can cooperate on surprisingly large scales. But these capabilities turn out to have unintentional consequences. Simply speaking, you could say that the human species has been too successful and, in some ways, too smart for its own future good," says Peter Søgaard Jørgensen, researcher at the Stockholm Resilience Center at Stockholm University and at the Royal Swedish Academy of Sciences' Global Economic Dynamics and the Biosphere program and Anthropocene laboratory.

He is the lead author of a new study published as part of a larger assessment in the journal Philosophical Transactions of the Royal Society B. The assessment gathers insights from a wide range of different scientific disciplines across the natural and social sciences and humanities, to understand how the Anthropocene evolved and how global sustainability can continue to evolve in the future.

The new study shows how humanity could get stuck in "evolutionary traps"—dead ends that occur from initially successful innovations. In a first scoping effort, they identify 14 of these, including the simplification of agriculture, economic growth that does not deliver benefits for humans or the environment, the instability of global cooperation, climate tipping points, and artificial intelligence.

"Evolutionary traps are a well-known concept in the animal world. Just like many insects are attracted by light, an evolutionary reflex that can get them killed in the modern world, humankind is at risk of responding to new phenomena in harmful ways," explains Peter Søgaard Jørgensen.

The simplification of agricultural systems is an example of such a trap. Relying on a few highly productive crops such as wheat, rice, maize, and soya, has meant that calories produced have skyrocketed over the past century. But it also meant that the food system has become very vulnerable to environmental change, such as weather extremes, or new diseases.

Of the 14 evolutionary traps, 12 are in an advanced state, meaning that humankind is on the verge of getting stuck to a degree where it becomes very difficult to get out. What's more, societies are continuing to move in the wrong direction in 10 of these 14.

Alarmingly, these evolutionary traps tend to reinforce each other. If societies get stuck in one dead end, they are more likely to get stuck in others as well. The two dead ends which currently are less advanced are the autonomy of technology—AI and robotics—and a loss of social capital through digitalization.

The new assessment also looks into why societies struggle so hard to move out of these traps.

"The evolutionary forces that created the Anthropocene do not work well at the global level. In today's global systems, social and environmental problems grow in places that seem distant to the societies that could prevent them. Also, addressing them often requires global collaboration on a scale that many evolutionary forces often do not align well with," says co-author Lan Wang-Erlandsson, researcher at the Stockholm Resilience Center at Stockholm University and the Royal Swedish Academy of Sciences' Anthropocene laboratory.

This does not mean that humanity is doomed to fail, argue the researchers. But we must start to transform our societies actively. So far, the Anthropocene has to a large extent been an unconscious byproduct of other evolutionary processes.

"It's time for humans to become aware of the new reality and to collectively move where we want to as a species. We have the capability to do that and are already seeing signs of such movements. Our creativity, and our power to innovate and collaborate equip us with the perfect tools to actively design our future. We can break out of dead ends and business-as-usual, but for that, we must nurture the capacity for collective human agency and design settings where it can flourish," explains Peter Søgaard Jørgensen.

He continues, "A very simple thing that everybody can do is to engage more in nature and society while also learning about both the positive and negative global consequences of our own local actions. There's nothing better than exposing yourself to what needs protecting."
