I think that emotional tears are likely to *not* be an early
feature of hominids, due to the involvement of the frontal lobes
in their production.

Now to consider other, less likely propositions is to speculate
wildly (and I mean wildly), but *if* you want to speculate wildly:

*If* emotional tears evolved primarily as an excretion device --
and I think that is extremely unlikely -- the evidence from these
terrestrial birds and reptiles would indicate it was for a very dry
climate rather than any aquatic environment.
