Semeraro, the semitic etimologies and the J haplogroup of Y human chromosome

Semeraro claimed that alla languages are derived from Akkadian, or, more precisely stated (although this precision is not present in his writing), that many words of obscure etimology in Latin and Greek derive from Akkadian. In this more limited sense the etimologies proposed by Semeraro are convincing: apeiron from eperu, mud, europa from erepu, sunset, and so on. These etimologies did not gain a general consensus; anyhow, it could gain support from the distribution of Y haplogroups, in particular from the J haplogroup, which more or less matches the semitic languages, which is present with high frequenecy in Italy and Greece, suggesting a possible semitic substratum for these languages.
