FACTOID!!
Lynx have adapted to life in the snow. They have huge feet that function as snow-shoes, allowing this tufted-eared cat to hunt in deep snow country without wasting energy by breaking trails.


Winging it


Winging it
A new theory proposing how birds developed the ability to fly with feathers is that feathers developed for aerodynamic control in animals which used a leaping mode of attacking prey. Conventional theory holds that flight developed because of the advantages the ability to fly gave the first birds. The new theory is that animals which pounced on their prey from above, off of rocks or trees, developed feathers and eventually flight through a need for better control of their descent onto their prey. The behaviours and physiology used for this control are what developed into feathers, wings, and other elements needed for flight. The theory was developed in part due to fossil evidence of animals which had feathers and wings, but did not have the other structures necessary to flight.
