Please help me identify a short story about time travel.

It is set during the last ice age as a modern man is living among a small community of early humans and is told to kill one of the last neanderthals as a test to see if he is really human or a savage.

The only other thing I remember the time travel device is referred to as a rainbow.

Does it have robots? :) –  DVK Mar 25 '12 at 13:36
Hm. Project Rainbow was the apocryphal Philadelphia Experiment. –  Mark Beadles Mar 25 '12 at 15:17
Is it possibly the same as this question? –  Mark Beadles Mar 25 '12 at 15:23
DVK No it does not, Mark, the story implied that "The Rainbow" was just a colloquial name for the method of time transport and sadly thats not the story I'm looking for. –  Vladimir Mar 29 '12 at 7:02

Probably also a long shot, but Riley's Journey (by P.L. Parker, 2007) could fit the description. At least for the Ice Age time travel and Neanderthals part. I am not sure about the Rainbow device though.

Is this one of the stories of "The Company" by Kage Baker? Maybe in the short story collection "Black Projects, White Nights"

Neither are short stories, but both Chad Oliver's "Mists of Dawn" published in 1952 and Victor Kelleher's "Fire Dancer" from 1996 have time travel and interaction with Neanderthals.

No time travel, but Lester Del Rey's "The Day is Done" is about the last Neanderthal trying to live with Cro-Magnons, but they end up killing him, I think.
