Design and Nested Hierarchies

Feathers and flow through lungs are classic bird features that are not shared with other groups. Do you see how this works?

As collapsing hinged screens are not shared with non laptop computers.
I see this as evidence for design. I don’t see this as any real case for what you are trying to argue that design had no part in this structure.
