# Early bird species 'could not flap wings'
|
|
|
|
## Some of the earliest species of bird would probably have been unable to
|
|
flap their wings because their feathers were too weak, new evidence suggests.

Researchers believe species such as Archaeopteryx, which lived 140 million
|
|
years ago and is considered to be the first true bird, may not have been
|
|
capable of powered flight.
|
|
|
|
Fossil studies of Archaeopteryx, which experts say looked like a feathery
|
|
dinosaur with wings, show that the species had thinner shafts on its feathers
|
|
than those of modern birds.
|
|
|
|
A team led by Robert Nudds, from the University of Manchester, calculated that
|
|
the feathers would have been too feeble for flapping wings and barely strong
|
|
enough to support gliding from tree to tree.
|
|
|
|
The same was true of Confuciusornis, a later bird that lived 100 million years
|
|
ago.
|
|
|
|
The researchers wrote in the journal _Science_: ''If Archaeopteryx and
|
|
Confuciusornis were flapping fliers, they must have had a feather structure
|
|
that was fundamentally different from that of living birds."
