This is almost definitely Dragon's Egg by Robert L. Forward; the primitive (very briefly) race are the cheela and they live on the surface of a neutron star. The cheela - who are described as the size of a sesame seed - live approximately a million times faster than humans, with a lifespan (for us) of about 40 minutes. From the human point of view the ...

This is probably Theodore Sturgeon's "Microcosmic God" (1941), where the main character creates a little world and forces the beings inside - called Neoterics - to evolve and solve problems for him. This, then, was the answer to his problem. He couldn't speed up mankind's intellectual advancement enough to have it teach him the things his ...

"Student Body", a novelette by F. L. Wallace, available at Project Gutenberg, also my answer to the old question Short story about human colonists vs. alien animals that evolve very rapidly. It doesn't start with bacteria, the progression of forms the "omnimals" take is squirrels, mice, rats, tigers, men. And we don't see what comes after men: "Don't you ...

Might you be thinking of "Mutation Planet" (1973) by Barrington J. Bayley as per Planet of animals that evolve in minutes? Filled with ominous mutterings, troubled by ground-trembling rumblings, the vast and brooding landscape stretched all around in endless darkness and gloom. Across this landscape the mountainous form of Dominus moved at speed, a massed,...

As Moo says in the comments the first book covers the science of this at great length. A summary can be found on wikipedia but you have the general gist. Built into the human genome are non-coding sequences of DNA called introns. Certain portions of those "non-sense" sequences, remnants of prehistoric retroviruses, have been activated and are translating ...

If it could have been a bit later Live Free or Die by John Ringo sounds right. An alien horde comes through a gate and Earth cheers - wow - advanced aliens - but they turn humanity into slaves to mine the earth of rich metals, etc. Then another alien race discovers what's happening but can't interfere with the other aliens on such a primitive planet. They do ...

Could it be Dragon's egg? Dragon's Egg is a 1980 hard science fiction novel by Robert L. Forward. In the story, Dragon's Egg is a neutron star with a surface gravity 67 billion times that of Earth, and inhabited by cheela, intelligent creatures the size of a sesame seed who live, think and develop a million times faster than humans. Most of the novel, ...

I believe you would be talking about the text by Ray Bradbury, "The One Who Waits." It begins in a well on Mars and the bacteria/alien takes over each human causing them to kill themselves then taking host of someone else. I live in a well. I live like smoke in the well. Like vapor in a stone throat. I don't move. I don't do anything but wait. Overhead ...

There are several reasons. (You already said this one) Both Sith and Jedi are not allowed to have children. For the Sith, it is not explicitly stated, but you can infer that, since the Sith religion is based off anger, hate, and suffering. I don't see a Sith ever loving someone once they're Sith. And a Force-sensitive who already has a family has little ...

While midi-chlorians help living beings communicate with the Force, the Force itself seems to act as a being in some ways. Specifically, it has a will, and is capable of prophecy, and potentially creating life. I find it unlikely that the Force, which is powerful and has a will, would want everyone to be in touch with it, because if everyone were Force-...
