Seriously, what are you talking about? What exactly took bilions of years to survive. Can you clarify what exactly it is you are asking.I don't understand your premise. If the species is still alive then I would say it has adapted quite effectively.You're smarter than that.
One BIG aspect of Evolution id adaptation to survive.
But adaption takes a LOOOOOOOOOOOOOONG time.
And the non-adapting species still survives.
It took billions of years to survive.
Prove it.
Show the stages of adaptation.
How long did it take the birds that can fly to grow wings?
They didn't grow wings, per se. Modern birds that fly are thought to have evolved from the same ancestor as the crocodile family. Over the course of millions of years, these dinosaurs developed first feathers, which fossil evidence suggests may have been for insulation (though they probably served other purposes as well such as camouflage or species recognition) and then the skeletal frame work that eventually favored aerial flight to running only on hind legs.
This isn't special to the evolution of birds alone because pterodactyls evolved flight independently, just as certain insects and mammals, such as bats, have also. Then there are animals such as flying fish and flying squirrels which, given the enough time and the right conditions, may be in the process of evolving into fully flying species.
