What I said was unwarranted was the assumption that it happened
during the transition from CA to hominid.

That hair loss is something which we want to investigate is a given.
We see no evidence that it happened during the transition, however,
since we see that in our own late-arriving species, there is
considerable variation in this characteristic. This would suggest
that it happened pretty recently, or possibly that it's a trait that
comes and goes extremely quickly.

If it first changed during the span of our species, it didn't
happen during the transition from the CA. If, OTOH, it both appears
and disappears that quickly (a few tens of thousands of years),
the trait could have disappeared and appeared several times in our
past, but the assumption that it happened during the transition
from CA to hominid would still be unwarranted.
