Genesis explains why human are without os baculum:
Megan Sauter February 18, 2020:
Ziony Zevit 2015 claims
The Biblical text says that Eve
was created from Adam’s tsela‘.
Although tsela‘ has traditionally been translated as “rib,”
Zevit argues that it is better translated as os baculum.

. "os baculum" is a bone used for penis erections,
in all primates except humans;
so Genesis might be a myth about
why humans don't have an erection bone,
just as it is a myth about other mysteries,
such as why childbirth is painful
and everyone has to die.
