Poem by Eeva Kilpi -- original?

[Nikama]

Hello,

Here is an English translation of a poem by Eeva Kilpi:

What is this sound that wakens me at night?

It is biology, it calls out its rights.
At night you can hear it more
clearly, when the
sociologists are sleeping.

Would anyone know the Finnish original? Thanks!

[Jukka Aho]

— Mikä on tämä ääni johon herään öisin?

— Se on biologia,
se huutaa oikeuksiaan.
Yöllä sen kuulee selvemmin
kun sosiologit nukkuvat.

Thank you, Jukka! (My Finnish is not yet good enough to guess the right conjugations and declensions for a succesful search term.)
