What causes a jalapeno to turn black (while it's still growing)?

A fully mature jalapeno pepper, regardless of size, generally exhibits small cracks around the shoulders of the fruit. A darkened area on the fruit indicates maturity and the initial stages of a color change in the fruit.

It is weird, b/c I picked one that was half black and still really small.
