Lactose Tolerance and Hebrews

A bit a a side entry into "Grandpa Was A Deity: How a Tribal Assertion Created Modern Culture"
The SCIENCE article, "Nomadic herders left a strong genetic mark on Europeans and Asians" [http://news.sciencemag.org/archaeology/2015/06/nomadic-herders-left-strong-genetic-mark-europeans-and-asians], points out that "Lactose tolerance was still rare among Europeans and Asians at the end of the Bronze Age, just 2000 years ago."
Given the time-frame, and the interaction between the milk of a cow and the meat of its calf when the latter is boiled in the former, lactose tolerance adds to the scientific explanation behind the dietary law prohibiting boiling meat in meat.
(Wall around Torah made it "No meat and Milk" but that is NOT the law, as shown by Abraham having cheese and meat meals for himself and his divine guests.) 
We do discover a reality -- Lactose Tolerance existed among the original Hebrews before it spread to the broader human population ... if it had not existed, then the laws from 3300 years ago would have prohibited the drinking of milk.

“Grandpa Was A Deity” another perspective

The answer is 141 generations ago. Allowing 30 years a generation, that yields a date of 2217BC. Obviously, this is not a precise date. But it is probably good to within a century or two. And that is interesting for two reasons. One is that the 23rd century BC is slap-bang in the middle of the period when Indian civilization was emerging. The other is that it coincides with a shift in both the culture of Australia and the composition of the continent’s wildlife.

The third thing that arrived in Australia at this time was the dingo. The origin of these wild dogs, which are believed to have outcompeted and exterminated the native thylacine (also known as the Tasmanian tiger, because it lingered into modern times on that dingo-free island), has always been obscure, though their resemblance to certain breeds found in India is well known.

The second shift was gastronomic. Sadly, the archaeological record has yet to reveal tandoori ovens or fossilized chapattis in Australia. But it does show changes at this time in the ways that cycad nuts—an important crop that Australians had long cultivated by the “fire-stick” method of burning vegetation that competes with the trees that bear them—were processed. Such nuts contain toxins. After about 2000BC several methods for removing these toxins, such as leaching them out with water and fermenting them away, spread through Australia. To this day, cycad nuts are familiar food in Kerala, in southern India. There, they are detoxified by being dried in the sun or by the fireside.

“Grandpa Was A Deity” & “Genesis of Genesis”  place the arrival in Australia to the Biblical Flood era – when man (those we know as the Hebrew-Aryans) spread across the globe.  Arpachshad, the son of Shem was born in Hebrew Year 1660, or 2104bce.  The calculated 2217bce equates to the birth of Shem (2202bce) who is actually mentioned – along with his two brothers – three years earlier (when Noah is 500).

As more scientific evidence emerges, there is more evidence that the Bible Calendar reports the migration of Hebrew-Aryans with their connection to Stonehenge and the other megalithic circles
