As I recall, the story starts with a small group of humans on a spaceship, traveling across the galaxy, to a planet that appears to have intelligent life. When they arrive, they find a humanoid civilization. These humanoids are much like humans, but their legs are set high, at hip level, and their arms are set low, much below the shoulder. The humans come down to the planet to meet and greet with the humanoids, who serve them drinks. The drinks have a sort of hypnotic/psychedelic in them, the effect being that each human, men and women alike, mate with various humanoids.
The humans return to their ship and travel (onward? heading back to Earth? not sure). The women all find that they are pregnant. The fetuses develop quickly and are born much sooner than usual. The babies have four arms and four legs each. They are amazingly strong and smart, and soon are able to teleport. They grow to juvenile stage within weeks, take one of the shuttle-craft, equip it with a hyper-drive they rigged together, and take off. At this point, the human men, one by one, go to each of the human women, cut out the embedded pregnancy prevention implants, and impregnate the women, so that they can't be re-impregnated by the other species.
The four-armed-four-legged "children" are actually the original race of our galaxy. To escape some lethal threat (I don't recall what it was), that race split themselves into "halves": humans, which they put on Earth, and the humanoids which they left on that other planet on the other side of the galaxy. Thus the original race "hid" from the lethal threat. They encoded within the humans the factors of curiosity and exploration, counting on the humans to eventually find the humanoids; they left other features with the humanoids (which I don't recall).
I don't recall what year .. or even what decade .. I read this. Could have been the '80s.
