Animals Shape ‘Shifting’ Due to Climate Change

Katerina Amaral, Reporter

Warm-blooded species are having shifts in their body. They are starting to have larger beaks, legs, and ears to adjust body temperature because the planet is warming up.

The discovery of evidence that animals are changing was founded by a team of researchers led by Sara Ryding of Deakin University in Australia. The biggest shifts in animals have been in Australia and North America. The adjustments within the animals are an example among the Australian Parrots species with beak size increasing by 4% to 10% on average since 1871. In North America, dark-eyed junco saw similar increases in beak size. Other shifts within animals showed wood mice having bigger ears and bats with larger wings. Scientists measure the evolution in animal limbs with the method called Allen’s Rule, which states animals in colder climates have shorter limbs and appendages than those in warmer climates.

With the world getting hotter, the animals are developing, but at the same time, we aren’t entirely sure the animals can keep it up to cope with the weather and if the shifts with animals’ bodies will help or not with survival. The changes aren’t super noticeable but definitely alarming. Now, if animals fail to control their body temperature, they can overheat and die quite easily.
