A 2012 PNAS paper, "Ultraconserved words point to deep language ancestry across Eurasia", attempted to answer that question, with surprising results. Researchers noted that these early 'root words'...

...can be predicted from information independent of their sounds. We showed in a sample of Indo-European languages that the frequency with which a word is used in everyday speech, along with its part of speech, can predict how rapidly words evolve, with frequently used words on average retained for longer periods of time

We have recently extended this result to include speakers from the Uralic, Sino-Tibetan, Niger-Congo, Altaic, and Austronesian families, in addition to Indo-European, plus the isolate Basque and the Creole Tok Pisin. Even in languages as widely divergent as these, we found that a measure of the average frequency of use predicted rates of lexical replacement as estimated in the Indo-European languages.

The study uncovered 23 "ultraconserved words" that "point to deep language ancestry across Eurasia". How deep? This subset of words, the researchers believe, "have remained associated with their particular meanings independently in separate branches of this superfamily since the end of the last ice age."

The 23 words identified by researchers included obvious ones (in terms of common usage) - “I,” “we.” “who,” “not,” “that,” “mother,” "man" - but also less commonly used words today which nevertheless were likely very important some 15,000 years ago, such as "fire," "ashes,", “bark,” and "worm".

Researchers noted that their unique approach in predicting these words independently of their sound correspondences "dilutes the usual criticisms leveled at such long-range linguistic reconstructions, that proto-words are unreliable or inaccurate, or that apparent phonetic similarities among them reflect chance sound resemblances."

So if you're planning on time travel back to the end of the last Ice Age any time soon, it might be worth brushing up on those 23 words...

Tsii’ is a hair and shitsii’ is my hair and this is where the word shitsi’ my daughter ’hair’ originated or shitsiłí my brother tsiiyeeł is K’ǫs diłhiłii (dark cloud and male rain) If address by Mother its shich’e’e or shits’ee’ shits’e’e my umbiblical origin something like that, Niłtsą zhiin éi shitsii’ wódadęę’ yadiłhił shitaa’ iiná shii’yis lah diyįn goh, ninitsekees at’e ditłee’, nitsiiyeeł éi hane’ bee’ ałch’į’ be’estł’ǫh, hadąą’ shįįh nichooni’yęęh t’adii kǫǫh, its your DNA a gene from the ancient carried on by matrilineal ways because women are Earth so her children stays with so is the Navajo matrilineal land based socio-cultural institutional system since Hajiinái

Hastoi Tsiiyeeł on the Aghąął in the summer Nidaa'

Dine Bikeyah Sumerian have Tsiiyeeł and so ancient as well attributed to origin of civilizations

Amazing to be interest in the image of ancient and contemporary Tsiiyeeł, to be Diné Americas here is another local the Mimbres with ancient Tsiiyeł as well of the contemporary time, having tsiiyeeł is not only pride in heritages but your the history of the world

Black on White in Diné way the left side of the body is male the side that whole the bow, Mimbre's image the round face is duality of male / female with square triangle eyes and mouth
