It can be seen on a cladogram that modern birds and reptiles share a common ancestor. select the piece of evidence that best supports this idea.
a)reptiles are also related to mammals.
b)birds have evolved into many groups
c)feathers are a derived characteristic that first evolved in reptiles.
d)birds have the derived characteristic of being warm blooded, like mammals.

The correct answer is - C) Feathers are a derived characteristic that first evolved in reptiles.

Nowadays it is widely accepted that the reptiles share a distant common ancestor, and that can be seen from multiple evidence, one of which is the evolution of the feathers, and surprisingly, it is the reptilians that developed them first, or rather, the dinosaurs. It was thought until recently that the dinosaurs have scaly skin as the modern reptiles, but multiple evidence came out that proved that big portion of the dinosaur species, especially the bipedal ones, were actually partially, or totally covered with feathers.

As the birds evolved from this types of dinosaurs, the connection is pretty clear. Add on that the structure of the bones which is pretty much identical to some of the dinosaurs, and also the evidence of transitional species from reptilians to birds, it is certain that the birds have their ancestry in the reptilians in the distant past.
