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:
