For humans, adapting to climate change will mostly be a matter of technology. More air conditioning, better-designed houses and bigger flood defenses may help lessen the effects of a warmer world. Animals will have to rely on changing their bodies or their behaviour. In a paper published inTrends in Ecology & Evolution, a team led by Sara Ryding, a professor in Australia, shows that is already happening. In some species of Australian parrot, for instance, beak size has increased by between 4% and 10% since 1871. Similar trends are seen in species of mice and bats growing bigger ears, tails, legs and wings.
All that fits nicely with evolutionary theory. “Allen’s rule”, named after Joe Allen, who suggested it in 1877, holds that warm-blooded animals in hot places tend to have larger appendages than those in mild areas. Such adaptations boost an animal’s surface area relative to its body volume, helping it to shed extra heat. Fennec foxes, meanwhile, which are native to the Sahara desert, have strikingly large ears, especially compared with their Arctic cousins.
Ryding’s team combined data from different species in different places. Now that they have little in common apart from living on a warming planet, climate change is the most reasonable explanation. Since any evolutionary adaptation comes with trade-offs, it is unclear how far the process might go. Bigger beaks might interfere with feeding, for instance. Larger wings are heavier, and bigger legs cost more energy to grow.
Honestly, studying a broader range of animals will help firm up exactly what is happening. For now, at least, the increase is small, never much more than 10%. That may change as warming accelerates. But it seems clear that the world of the future is not just going to be hotter than humans are used to. The animals living in it will look different, too.
