Unique versions of the lactase gene found in the genomes of East Asian people may have increased in prevalence within the ...

The gene that enables East Asian adults to drink milk without getting side effects like stomach cramps was probably inherited from Neanderthals, thousands of years before humans started consuming ...

A small team of computational and evolutionary biologists from the University of Chinese Academy of Sciences, Zhongshan ...

The emergence of blood abnormalities, an adult ability to digest milk, and changes in our physical appearance point to the continued evolution of the human race. NIH’s plan to reduce indirect funds ...

“The work is interesting as many ethnic groups from Africa were studied and haplotypes were constructed that gave data about the migrations of the LP [lactase persistence] alleles,” Irma Järvelä of ...

A second example of adaptive divergence among human populations is related to the persistence of lactase production in adults. Lactase production in the gut functions in the digestion of the milk ...
