A Forthcoming Biological Revolution
Adrian Woolfson's analysis proposes an imminent biological revolution driven by advancements in science and technology. This revolution is expected to enable the design and construction of artificial species, which would co-exist with naturally evolved organisms.
Drivers of Change
Key developments identified as propelling this revolution include:
- Advanced DNA Synthesis: Technologies like the Sidewinder method developed at Caltech facilitate the rapid and efficient construction of large and complex DNA fragments, making it possible to synthesize entire genomes.
- Artificial Intelligence in Protein Research: AI, particularly systems such as AlphaFold2, has resolved the challenge of predicting how amino acid sequences fold into three-dimensional protein structures. This capability allows for the creation of novel proteins with specific functions for use in medicine and other fields.
Shift to Generative Biology
The ability to synthesize genomes and predict/design new proteins marks a transition in biology from a descriptive discipline to a generative one.
This means future scientific efforts will focus on creating new forms of life rather than solely cataloging existing ones.
Potential Applications and Modifications
The creation of synthetic species could yield numerous benefits, including:
- Production of biofuels, medicines, and biosensors.
- Development of drought-resistant crops.
- New methods for constructing structures, such as "growing houses."
There is also potential to enhance existing biological forms, for example, by re-engineering anatomical features like the human spine, which is described as suboptimal for bipedalism.
Identified Risks and Concerns
The prospective biological revolution also carries considerable risks:
- Bioterrorism Potential: The increasing accessibility of benchtop DNA synthesizers and AI tools could facilitate the creation of human-made pathogens.
- Ecological Instability: Manipulating entities such as bacteriophages could inadvertently disrupt natural cycles, like the ocean's carbon cycle, and potentially exacerbate climate change.
- Ethical Implications: Expanding genetic modifications in mammals, such as making mice more humanlike for drug testing, raises complex ethical questions about the limits of intervention.
- Monitoring Difficulties: The widespread availability of genomic technologies will complicate efforts to monitor what is being created and by whom.
Perspective on Progress
Woolfson asserts that progress in this field is inevitable and necessary, citing significant potential benefits for humanity, the planet, and the animal kingdom.
While he advocates for restrictions on "designer babies" and "parentless humans," he argues against a moratorium on AI-led genomics research, suggesting such a ban would be ineffective. He acknowledges the risks of unintended consequences.
