Here, we use a developmental approach to analyse molecular mechanisms in feather-branching morphogenesis. We have used the replication-competent avian sarcoma retrovirus to deliver exogenous genes to regenerating flight feather follicles of chickens.
Can you explain this to us?
And then summarize what the new discovery is?

Elementry, my esteemed colleage.
As it's plane to see, this bird was killed because dinosaurs failed to grow armor-plated feathers.

a.) "Here, we use a developmental approach to analyse molecular mechanisms in feather-branching morphogenesis": We are watching, at the molecular level, how different parts of a feather form as it grows.
b.) "We have used the replication competent avian sarcoma retrovirus" : We took a virus from birds -- a virus that was altered, but could still replicate: "...to deliver exogenous genes" : We used that virus to deliver genes created outside of the bird -- exo=outside, genous=created): "to regeneerating flight feather follicles of chickens."
So, we used a bird virus, put our controlled gene in the virus, used the virus to deliver the new genes to the replicating feather, and watched, at the molecular level, what happened when the controlled genes were expressed. Does that help :)
