Vacuumorph

Left you see the original design by Dougal Dixon, right my own slightly edited version of the Vaccuumorph.

The Vaccuumorph is a human species from the furture designed to work in the vacuum of space. They can't breed, have additional organs for storing oxygen, a hard outer skin grafted on them for withstanding cosmic rays and vacuum.

I made the feet more like monkeys for grapping, and gave them a tail for grapping as well.

All in all I am not sure whether such beings are actually possible. According to Dixon they are partly engineered and partly grafted. Organs that could not be grown on them via genetic manipulation where later grafted onto and into them. Despite the exterior, they still have quite a human like skeleton.
Hard to tell whether this bein can still be considered a part of evolution. While having only one gender, if it can be called that name in this case, is not unusual in evolution, the gentic engenering and body grafting have left these beings sterile.
