Directions (16 – 21) : Study the following information carefully and answer the questions below:

Modern birds evolved from ground – dwelling reptiles as their increasingly refined parenting

skills led them into the trees, where they could better protect their young, proposes a researcher at the

University of California, Davis. This new theory, contradicts the two leading theories on the evolution

of avian flight. “The evidence indicates that a whole site of behavioral and physical traits, including

feathers and wings evolved along with improved parenting and brood care traits,”said James Carey, a

UC Davis demographer and ecologist.

Once the precursors to birds began to fly, the ecological interplay of flight and parental care

may have been mutually, continuing the evolution of both traits and accelerating the rate at which the

physical features of the modern bird were acquired. The origin of bird flight is a fundamental issue in

biology and in overall evolutionary theory. Many scientists point to the fossilized specimens of

Archaeopteryx as evidence that there was a transitional vertebrate species that developed during the

evolution from reptilian dinosaurs to birds. Furthermore, they suggest that the development of flight

may explain why bird – like dinosaurs avoided extinction.

Until now, there have been two basic theories on the origins of bird flight. The first, the

arboreal theory, is a tree to ground model, suggesting that bird’s primitive ancestors were tree

dwellers that leapt from branches. Through the ages, the ability to glide and later fly developed

because gliding slowed their fall to earth when they missed a branch. The second, the cursorial theory,

is a ground up model that suggest that birds evolved from four legged reptiles. According to the

theory, scales on these creatures gradually developed into front limbs with features that gave them

upward thrust when they ran and eventually enabled them to fly.
