Ostrich birds become heavy and incapable of flight after the dinosaurs, our main enemy, disappear forever from the earth.

Previously many scientists thought that the ancestors of the ostrich is not flying. But some biologists of the Australian National University said that the ancestors of ostriches each flying in the sky.

Telegraph said Dr. Matthew Phillips, a biologist at the University of country Australia, and colleagues analyzed the genes of the ostrich subspecies live in Africa, Australia, South America and New Zealand to justify speculation their. Results show that we lose the ability to fly after the dinosaur extinction.

When the dinosaur is not extinct ostrich is capable of flight.

As the team’s arguments, when dinosaurs still dominated the globe, they are enemies of many animals. Situations that led to property ostrich body compact to flying easy. Extinction of the dinosaurs 65 million years ago caused more food becomes plentiful. Because food may have too many things on so as to better. The heavy body, plus the disappearance of the dinosaurs, making ostrich gradually run more like flying. After millions of years, finally able to fly them permanently lost.
