Can You Evolve a Second Pair of Pectoral Muscles Without The Need for Flight?

Somewhere on DeviantArt, there is an insightful tutorial by someone named "Uzlo" on how to create anatomically believable angels. Among the instructed details is the possibility of developing a second pair of pectoral muscles for the wings.

But in an alternate Earth, humans have evolved this second pair without the need for flight. Is this feature within the realm of primate evolutionary possibility? And if yes, then what would they be used for?
