To move in regular procession through a system.
"The delegates evolved slowly from the lobby into the grand hall, filling each room as they went."
In plain English: To evolve means to gradually change and grow into something better over time.
"The company decided to evolve its business model to stay competitive in the changing market."
Usage: Evolve means to develop gradually over time, such as species adapting or ideas improving, rather than moving physically from one place to another. Do not use this word when describing simple locomotion; instead, choose "migrate" if you mean traveling in regular procession through a system.
The word evolve comes from the Latin verb ēvolvō, which literally means "to unroll" or "unfold." It traveled into English with this original sense before its meaning shifted to describe gradual development over time.
