I am puzzled. Is this illustration, "the big wing switch"on the link below,
from the Nature article mentioned?
If so, can anyone explain to me just where wings were lost and regained.
I see four separate origins of wings and two subsequent losses but no
regaining of wings after they were lost. I haven't read the article but was
shown the cladogram (in an article in New Scientist) by a colleague who
asked this same question.
Some simple explanation would be appreciated. After all these prestigious
journals can hardly be wrong, can they?
