Since dinosaurs had mammalian red blood cells, they could not have
evolved into birds. If they did, they would have died in seven to 14
minutes, as birds’ red blood cells are unable to change shape in order
to pass through the capillaries in the brain of dinosaurs, thus
resulting in lack of oxygen supply to the dinosaur’s brain.

Correction: should read "unable to change shape fast enough"

lack
Should read: "thus resulting in insufficiency" of oxygen supply to the
dinosaur’s brain.
