Coral assisted evolution research is advancing, but not fast enough to matter. That is the blunt conclusion of an international review led by Dr Adriana Humanes of Newcastle University and co-led with the Australian Institute of Marine Science, published in Nature Reviews Biodiversity on 30 March. Drawing on 28 experts, the paper assesses progress on methods that accelerate corals' natural adaptation to heat and finds the field's current pace outmatched by the warming of the oceans.
The authors respond with a structured agenda: nine research priorities and three critical catalysts. These include scaling experiments from laboratory tanks to large field settings, securing long-term funding that matches coral biology, and protecting experimental coral hubs from the extreme events they are designed to study. The mismatch they highlight is structural: corals take three to seven years to mature and reproduce, while most research grants run for only three.
The review is candid that assisted evolution is no silver bullet, and that cutting greenhouse gas emissions remains the first-order priority for reef survival. But with mass bleaching events arriving faster than the science designed to counter them, the authors argue that the window for building credible, field-tested interventions is narrowing, and that coordination across institutions and funders must improve now.
