Which is the correct sequence of events in the gene-culture evolution of lactose tolerance in humans?
A) domestication of cattle, fermentation of milk products, mutation of LCT gene, rise in frequency of LCT mutation
B) domestication of cattle, mutation of LCT gene, fermentation of milk products, rise in frequency of LCT mutation
C) mutation of LCT gene, domestication of cattle, fermentation of milk products, rise in frequency of LCT mutation
D) mutation of LCT gene, rise in frequency of LCT mutation, fermentation of milk products, domestication of cattle

The correct sequence starts with the domestication of cattle, which provided a steady supply of milk. This was followed by the development of fermentation techniques to make milk products more digestible. The mutation of the LCT gene, which allowed for lactose tolerance, occurred next. Finally, there was a rise in the frequency of the LCT mutation among populations that raised cattle and consumed milk products, demonstrating a classic example of gene-culture coevolution.
