Read the following passage carefully and answer the questions given below.

It is an unlikely relationship, but the humble pigeon is a direct descendant of the group of dinosaurs that also includes the mighty Tyrannosaurus
rex.
The two species share a remarkable biological past. Museum palaeontologist Professor Paul Barrett explains how our new understanding of
dinosaur evolution is transforming the way scientists think.
Birds that fill the world's skies today are living dinosaurs, reminders of a distant and strange past. Decades of major new discoveries and studies
have A. _________ researchers that there is a direct link between modern bird species and theropod dinosaurs. Once dinosaurs were thought of as
scaled-up lizards, but now they are regarded very differently.
Paul says, 'Dinosaurs have always sparked the imagination, but our views on these spectacular animals have changed continually through time.’
'Our image of dinosaurs is now quite different from that put forward by the first palaeontologists working on these animals.'
We are in a period that palaeontologists call the 'dinosaur renaissance'. It began in the 1960s with the revolutionary discovery of Deinonychus, a
small predatory dinosaur that lived about 115 million years ago. It not only showed unique similarities to birds, but also appeared to be an
intelligent, fast-moving pack hunter, rather than a slow, plodding reptile.
New work on old specimens, and the discoveries of dinosaur and early bird species in the field, supported the idea that dinosaurs were the direct
ancestors of birds. Many features and behaviours that characterise living birds were also found in their dinosaur ancestors.
Perhaps most surprising of all was the discovery of dinosaurs with feathers, completely changing the scientific community's perception of their
appearance and behaviour.
Deinonychus was a theropod, one of a group of bipedal, carnivorous dinosaurs that also included Tyrannosaurus rex. Our knowledge of these
creatures is constantly changing as new fossils are unearthed.
During the course of their evolutionary history, the body size of some theropod groups gradually decreased - a trend that, together with many
other changes to the skeleton, ultimately led to the appearance of birds.
Paul says, 'In 1996 the first feathered dinosaur was announced and many others have come to light since. This work has shown that Deinonychus,
originally depicted as a scaly dinosaur, was actually feathered.'
