Bold claim. However, reading your quote shows no evidence, just descriptions of what there is. Moreover, the challenge is not addressed.
Perhaps you didn't read it.
The ancestral configuration of the vertebrate head has long been an intriguing topic in comparative morphology and evolutionary biology. |
And they still have no idea.
One peculiar component of the vertebrate head is the presence of extra-ocular muscles (EOMs), the developmental mechanism and evolution of which remain to be determined. |
See?
No?
Let me spell it out clearly for you. Here, we'll type slowly:
The challenge: Describe how this evolved.
Meyers: I don't know.
Your source: It is not known how this evolved (ie, I don't know).
It must be embarrassing to consistently have your own sources admit that they can't solve the problem you Googled them to answer.
Next time perhaps read them first?
No?
OK. :idunno:
