Protostellar disks are mass reservoirs responsible for transferring material from the infalling envelope to protostars and forming future planetary systems. These disks are now commonly found in the earliest stages of protostellar evolution, and recent observations have even revealed the presence of discrete, extended, and infalling molecular gas structures, commonly referred to as "accretion streamers". These structures funnel mass directly from the surrounding protostellar envelope to these young disks, exhibit various morphologies, and are traced by several different molecules. But what are these structures? Are they all created equally? And what is their role in protostellar disk formation and evolution? In this talk, I will discuss my recent work as part of the eDisk ALMA large program on a large-scale study of extended structures in our sample, as well as, connect with previous observations and numerical simulations.
