The climate is changing faster than many species can adapt, so scientists are trying to speed up evolution by fostering the spread of creatures who can take the heat. Think of it as natural selection with a little boost from humans—or, in some cases, robots.
To that end, Australian scientists Peter Harrison and Matthew Dunbabin recently teamed up for a world-first field experiment. A robot Dunbabin designed carried coral larvae that Harrison had gathered and dispersed them on part of the Great Barrier Reef.
What makes these larvae unique and the groundbreaking experiment especially promising is that the they are heat-tolerant, meaning they not only can survive, but flourish, in warmer waters.
The robot has the capacity to carry around 100,000 microscopic coral larvae per mission, and Dunbabin expects to scale up to millions. The robot gently releases the larvae onto damaged reef areas allowing them to settle and, over time, develop into full-grown corals.
