There isn't an IOTA of evidence that language evolved from animal signals, or that a Proto-Indo-European people ever existed.
But what's truth got to do with it?

entry:IOTA YoD (letter YoD) Yod-Vav-Dalet
YO(D)T________יוד_________[YoD --> IOT]
ROOTS: IOTA is the ninth letter of the Greek alphabet. The tenth letter of the Hebrew alphabet is יוד YoD.
The illiterate ancient Greeks got their Alpha-Beta or alphabet from the Semitic Aleph-Bet. But cherished myths, like the cultural supremacy of the Greco-Romans die slowly. Similarly, there is not an IOTA (the smallest amount) of evidence than a Proto-Indo-European people or language ever existed.
The lower case IOTA is as small as the Hebrew י /Y , formally called יוד YoD, which is why IOTA means a small quantity or a JOT. Biblical Hebrew letters (like weekdays and months) were numbers, not names. This is another reason why the one-letter translation schemes of Benner, Misler etc. are misinformed.
BRANCHES: JOT is from Yod-Dalet, just as surely as Jerusalem is from ירושליםYeROOSHaLaYiM, Judah is from יהודה YeHOODaH (JEW is a clipped JUDEAN), or Jethro is from יתרו YiTRoW. Another “small thing” that sounds like JOT is יד YaD, a peg, handle or hand (Exodus 26:17).
The Hebrew יYoD / Y is most often rendered I: Israel is from ישראל YiSRAeL in Hebrew, and Ionia is from the name יוןYaVaN (Genesis 10:2 - where the Greek brother of Media, Moscow and Thrace is rendered Javan in English Bibles). More examples of Yod / Y taking an i are at “IS” and "JINX."
As for JOT and YoD as a J-like soft-G sound, note the Italian take on י Yod-names like 1) יעקב Ya[A]KoaBH (Jacob), 2) יוסף YOA$aiF (Joseph), and 3) יפתYaFeT (the real Proto-Indo-European and possible source of Jupiter): 1) Giacobbo, 2) Giuseppe and 3) Geppetto.
Also, see most J entries , like “GHERKIN.” More Greek versions of Yod at “EON” and “FENWAY.”
