<span>Lactase persistence, the ability to digest the milk sugar lactose in adulthood, is highly associated with a T allele situated 13,910 bp upstream from the actual lactase gene in Europeans. The frequency of this allele rose rapidly in Europe after transition from hunter–gatherer to agriculturalist lifestyles and the introduction of milkable domestic species from Anatolia some 8000 years ago. Here we first introduce the archaeological and historic background of early farming life in Europe, then summarize what is known of the physiological and genetic mechanisms of lactase persistence. Finally, we compile the evidence for a co-evolutionary process between dairying culture and lactase persistence. We describe the different hypotheses on how this allele spread over Europe and the main evolutionary forces shaping this process. We also summarize three different computer simulation approaches, which offer a means of developing a coherent and integrated understanding of the process of spread of lactase persistence and dairying.</span>
The right option is transitive
inference
Transitive inference is a form of
deductive reasoning in which the relationship between items that have not been
clearly assessed is derived. Transitive inference gives the ability to conclude
that if item A is related to Item B and Item B is related to Item D, then Item
A must be related to Item D. From the question given above, the understanding
demonstrates transitive inference.
B is the best life ever and the worst time ever we will have a bad day of that bad day so we gotta
