The upper limbs of birds, bats, and dragonflies, for example, are all considered as wings, because they have the same functional role: they make the animals capable of flying.
Homology/Homoplasia: On the other hand, the considerable anatomical differences of the wings are decisive.
Language: Problem: it can have many different functions. Here, we must define the identity of a feature.
Problem: the choice of the feature is dependent on the interests. Of course, people can do things with their language that animals cannot.

I 332
Likewise, e.g. hummingbirds can do things with their wings, which eagles cannot do with their wings. > Order,> identity,> difference.
They share a common feature despite the differences.
Language/Allen: one does not have to ask what it is, but what it does!
