Mutant animals and climate change: the Australian study

A recent study has shown how the effects of climate change are giving rise to the phenomenon of so-called “mutant animals”

The effects of global warming are now visible even in everyday life: sudden atmospheric changes with often disastrous consequences, temperatures unsuitable for normal averages of the period and other phenomena that have unfortunately become part of the routine of the inhabitants of the planet that can not but alarm scientists and be reported by the media.

However, not only climate, temperatures and land conditions are an indication of the changes we are witnessing: there have also been consequences in the very bodies of some animals. A large group of researchers has in fact participated in an interesting and revealing study, conducted over a period of years and in many places on the Planet.

According to this recent investigation, promoted by a team of scientists from Deakin University in Australia, in the morphology of some animal species are measurable increases in the size of certain body parts.

Global warming and animal mutations
These are not infinitesimal changes observable with difficulty, but quite the opposite: the researchers point out that the mutant animals they are dealing with show visible changes in the size of certain parts of their bodies, and this undoubtedly links the mutant animals to the problem of global warming.

Due to climate change, not only the habits related to animal feeding and migratory routes have changed, as well as several behaviors that have varied to cope with the different consequences of global warming: with the study of the researcher Sara Ryding and her team, published in the scientific journal “Trends in Ecology & Evolution” it has been shown that some species present measurable changes in some parts of their body.

The Australian study concerns the mutations of some warm-blooded animals present in various parts of the world, from Australia itself to Asia, from North and South America to Africa.

Some of the animals that have mutated due to climate have been studied and brought up as examples in the article. These are some species of Australian parrots whose beak size has increased from a hundred and fifty years ago. The same has also been verified in other birds such as gang gang cockatoos, Sturnus Vulgaris and dark-eyed juncos.

It is not only feathered animals that we are talking about, talking about mutant animals as an effect of climate change: also a mammal like the shrew (Sorex Cinereus) has undergone an elongation of tail and legs, as well as in some wild rabbits there has been an elongation of the ears.

Finally, in bats, wings have grown by more than 1%: as you can see, all variations on the ends of the animals’ bodies (beaks, legs, tails, wings) are changing in order to withstand the rise in average temperatures on the planet.

Thanks to these parts of their bodies, in fact, they are able to release heat to rebalance their internal temperature and avoid overheating that would lead them to death. An effect of evolution closely linked to climate change that has occurred, say the scholars who conducted the important research, in a relatively short period of time. In some species, even, mutations have occurred in the time of a single generation.

A proof of how animals are formidable in adapting their morphology to the surrounding environment to ensure the survival of their species.
