Numerous small holes in sill plate and studs

In the basement of a house I inspected, there were numerous holes drilled into the sill plate and wooden studs. Basement was partially finished, but in the open areas - these holes were visible. Anyone know what the holes might have been drilled for? Thanks in advance for any insight or clarification.

I can think of many things, such as paneling, peg board, etc… Honestly, you don’t give us much to work with! Broader view pics can be very helpful.


My apologies for the lack of details. The basement was mostly finished, but whatever was visible looked just like these 2 pics. They are about 1/2" holes drilled randomly into the wood. No specific pattern from what I could see.
