Most person's familiar part, we talk about simple point. Lactose is not able to bear or endure the intestines and stomach that sufferring essence is you cannot decompose lactose, then indigestion is caused unwell. Common mammal for instance pig, development arrives after certain level in their intestines and stomach those who be aimed at lactose is enzymatic can go on strike, piggy also ablactations, use up the nutrition of the sow no longer, after this calculates a mother to forage go answering them somes surviving opportunity is great also more singlehanded. The person also is so return a responsibility, so adult of the much on the earth -- looking is when or which data -- do not suit to drink a milk actually, since ancient times.
But since most person is drunk,do not come, develop everywhere for what went out to suckle kind of food? Estimation of a reason is the loss that the nutrition that domestic animals grandma brings and economic benefits lid passed have loose bowels. After to people the society does cheese, gains is more remarkable. To inchoate horde, get, save and line-haul is convenience, and flavour is broad still with food is real very difficult give up; And be in arid area, animal grandma also is water is important replace.
Perhaps see this intestines and stomach that you had understood to the person of what area has digestive milk sugar. Depasturing aptly (perhaps say unsuited cultivation) area and desert desert, after manhood can grandma of drinkable domestic animals absorbs nutrition completely, return won't humoral because of diarrhoea prediction of a person's luck in a given year, the choice advantage that this brings is not little.
It is actually in the inchoate nomadism society with intense competition, the grandma that drink cultivate meets the person of have loose bowels be sifted more easily naturally. This kind " choose " of pressure big, let 3 areas be in at least before 7000, formed lactose to be able to bear or endure severally bear blood relationship: Boreal Europe (traceable present Danish area) and Africa east, on the west two sides. The gene change that this 3 ground appear also differs individually, but changed with efficient way same lactose disassembles labour, namely lactose dehydrogenation is enzymatic / Lactose Dehydrogenase. As nomadic a wave is invaded, by agricultural people absorb, and have trade relations of each district intercourse is permeated each other, these hematic arteries and veins just distributed between the mainland come.
Asia
Resemble old father and me the word of such ancestral home China, you live to often can encounter dietary problem in Italy, because of here popular famished look has grandma stuff almost, it is the main source of native nutrition.
The food here develops the Asia is another road. Evidence makes clear in be apart from controlled 10000 today, the Huanghe valley (like relics of Na Zhuang head) begin somebody to raise chicken. Rasorial flesh and egg are outstanding protein origin, and the egg is convenient save carry, it is easy to get, the cheese of similar nomadism area. Gallinaceous type of build or figure is fine, lifecycle is shorter, raise rise than lactation kind draught animals save trouble. And be apart from today the magnetism hill culture 8000, had had a mark that raises a pig. (Allegedly, because sow of & of flavour raw meat or fish does not like to cooperate,pig grandma does not have popularity is)
My hour lives in Singapore, had not seen bright grandma in place. The beverage of milk powder modulation is to have, but the person all round still is commonly more habitual beans grandma. Now, fabaceous grandma also becomes in the west everywhere was seen, many people think milk is adipose and too much go against health -- deficient is friendly, if you drink milk abdomen the meeting is afflictive, the recipes that returns to old times then is good.
