Humans are not the only ones adapting to the effects of global climate change.

Animals are also adapting to the environmental changes — as some warm-blooded animals are beginning to "shapeshift" their bodies in response to shifts in climate, according to a recent study in Trends in Ecology & Evolution led by Sara Ryding, a researcher at Deakin University in Commonwealth of australia.

In the study, researchers identified new show that supports the theory that some warm-blooded animals are experiencing changes to their bodies due to the ascent temperatures, resulting in larger legs, ears and beaks in some cases.

The researchers noted that co-ordinate to a principle known as "Allen'due south Rule," warm-blooded animals living in colder climates tend to take smaller appendages (like beaks or legs) than animals of the same species living in warmer climates.

"A lot of the fourth dimension when climate modify is discussed in mainstream media, people are request 'can humans overcome this?', or 'what technology can solve this?'," Ryding said in a news release from Cell Press.

She said that just like humans, animals also have to adapt to climate changes, as shapeshifting for some of the warm-blooded animals are occurring over a far shorter timescale than would usually be expected.

"The climate change that we take created is heaping a whole lot of pressure on them, and while some species will adjust, others volition not," Ryding said.

Some of the most compelling evidence of anatomical change was found in birds in Australia and N America, according to researchers.

Certain species of Australian parrots have demonstrated about 4%–10% increase in the size of their bills since 1871, which researchers attribute to rising temperatures.

In North America, the dark-eyed junco also has seen an increase in neb size. Larger beaks help birds dissipate excess body heat more than effectively, the report said, which is a useful trait as global temperatures rise.

It's often difficult to determine why, exactly, a species evolves in a certain way. Just co-ordinate to Cell Press, the researchers said they're seeing this trend in many dissimilar types of species and locations — and experiencing climate change is what they all take in common.

"Shapeshifting does non mean that animals are coping with climate change and that all is 'fine,'" Ryding said. "It but ways they are evolving to survive it."
