As seen in a decades old theory, lactose intolerance is believed to be a genetic mutation that gave certain groups a distinct survival advantage, and consequently was passed down to their offspring. Ellastolz25 (talk) 17:59, 7 November 2019 (UTC) Its important to keep in mind, that the gene mutation is not always inherited by the offspring which can lead to lactose intolerance.

In most societies, the lactase enzyme turns off in adulthood, resulting in lactose intolerance. However, in certain groups of Northern and Central European descent, as well as African and Middle Eastern descent, the lactase enzyme is still active. Ellastolz25 (talk) 18:07, 7 November 2019 (UTC)

Those populations most likely to be lactase persistent in this room are those whose ancestors were the ruminant herders, specifically residents of northern and northwestern Europe, Scandinavians, those from the northwestern region of the Indian subcontinent, and those living as Bedouins in desert areas (e.g., Jordan, Saudi Arabia). Other populations domesticated animals that could not be milked, such as the pig. Thus, they never developed the mutation. This includes the remaining 75 percent of the world's peoples(3,5). As many as 90-100 percent of Native Americans, Native Africans, Asians, and Eskimos are lactose intolerant(6). As many as 80 percent of African-Americans and MexicanAmericans experience LI. This information concludes that humans are naturally lactose intolerant, and only through the inclusion of domesticated animals was the Lactate gene altered.Dlongo17 (talk) 19:56, 14 November 2019 (UTC)

'''Populations that domesticated animals that could be milked continued to be lactase persitant in areas such as North and North western Europe, Scandinavia, the modern Middle East and Northwestern India. Populations that raised animals not used for milk made up the rest of the world's populations. These populations tend to have 90-100 percent of a lactose intolerant rate ''' — Preceding unsigned comment added by Kprentice23 (talk • contribs) 18:14, 12 November 2019 (UTC)

Around 8,000 years ago in modern day Turkey, humans became reliant on newly-domesticated animals such as cows, sheep, and goats. This newfound reliance resulted in higher frequency near the gene responsible for producing the lactase enzyme.Abbysearcy14 (talk) 23:49, 13 November 2019(UTC) Lactase persistence in adults is a result of the coevolutionary process between agricultural development and genetics.Abbysearcy14 (talk) 23:49, 13 November 2019 (UTC) Prior to the evolution of lactase persistence, most adults could not comfortably ingest milk. But, several thousand years ago, the first evidence of lactase persistence was discovered in Europe. Abbysearcy14 (talk) 23:54, 13 November 2019 (UTC)

Lactase persistence can be found among people with some European ancestry but is rarely found elsewhere on the planet(with the exception of some groups in Africa, the Middle east, and Southern Asia). However, it's believed that the derived allele for lactase persistence is originated somewhat recently and is strongly selected among central Europeans. This leads experts to believe that the the allele for lactose persistence is strongly associated with cultures that practice lactose consumption. As such, lactose intolerance is likely not an evolved trait but rather a natural state of being for humans consumption of other animals lactase. . — Preceding unsigned comment added by Bullfighting48 (talk • contribs) 02:23, 14 November 2019 (UTC)

According to 70's physical anthropologist Frederick J. Simoons the first animal that was domesticated was sheep around 11,000 ya, followed cattle and goats 9000 ya. However, according to Itan et. all the allele for lactase persistence in humans was not found until about 7500 ya. This also indicates that lactose consumption of another animals is not a natural state of being for homo sapiens. — Preceding unsigned comment added by Bullfighting48 (talk • contribs) 01:26, 15 November 2019 (UTC)
