A brand new research has discovered that flightless birds had been extra widespread on the planet earlier than actions by human beings began main them to extinction.

For instance, the attribute of flightlessness in birds made them extra liable to be extinct as they had been simpler to seek out by human beings and their pets like cats and canine. Of the 581 fowl species that went extinct, 166 didn’t have the power to fly. At present there are solely 60 species of flightless birds.

Birds often advanced out of their means to fly when there was no presence of their standard predators, like in islands. A lot of the islands on Earth had flightless birds on them earlier than people appeared. In accordance with Dr Sayol, “With out these extinctions we might be sharing the planet with flightless owls, woodpeckers and ibises, however all of those have now sadly disappeared.”

The research has been printed within the journal Science Advances.
