Since the 1800s, more and more evidence has accumulated.
What's the most iconic feature of birds?
Their feathers.
Evidence for the relationship between feathers and scales isn't just found in the fossil record.
paleontologists like Steve have discovered the beginnings of feathers in some very familiar dinosaurs.
These fluffy strands were probably developing as a kind of insulation as dinosaurs' metabolisms increased.
Mammals were doing the same with hair.
Eventually, these protofeathers got more complex.
Alongside wings, another archetypal bird feature developed, the wishbone.
Once you have your prey, what do you do?
Rip it apart and chew it up.
Except the birds today aren't much for chomping because they don't have teeth.
They have another tool in their kit that means they can tackle different food sources.
Coming up, how did birds end up as the only dinosaur survivors of the asteroid?
When Steve points out that there are more species of birds today than mammals, it's strange to think that we're still living in the age of the dinosaurs.
Since childhood, we've all been taught that that ended with a giant rock slamming into the earth 66 million years ago.
And in a way it did.
All the other dinosaurs went extinct.
But somehow a single group of birds survived.
How did they do it?
