Scientists are worried natural selection won’t be able to keep up with the warming temperatures.
Animals are "shape-shifting" and evolving larger features as the planet warms up, a new study claims.
The research was published Tuesday in the journal Trends in Ecology & Evolution.
Among the findings was a claim Australian parrots, like the gang-gang cockatoo and red-rumped parrot, have shown up to a 10 per cent average increase in bill size as the temperatures in their natural habitats increase.

The parrots aren't the only animals to show a shift in shape.
Other species of birds in North America and Australia have shown an increase in bill size, wood mice have bigger ears, and some bats are flapping about on larger wings.
The larger features help the animals stay cooler as they offer a greater surface area to release body heat.
However, scientists are worried natural selection won't be able to keep up with climate change.

"It's alarming that we are seeing these responses so early on in the climate crisis," study author Sara Ryding, a researcher in the School of Life and Environmental Sciences at Deakin University, told CNET.
"We don't know if they'll be able to keep up as the crisis worsens."
