The kanji 丁 is pictographic in origin. It originally depicted a nail or a peg. The shape of the nail became simplified over time, which explains the shape of 丁 as it exists today. The meaning evolved from "nail" or "peg" to a more abstract sense of a "unit" or "individual," and also implied a sense of solidity or "fixing" something in place, just as a nail does.
