Meanings of lactase persistence in English

There may have been several factors promoting lactase persistence, not just one.

We assessed the potential for using genetic variation in lactase persistence as a tool for the study of this relationship.

It's unclear whether lactase persistence is still being actively favoured by evolution, and thus whether it will become more widespread, says Swallow.

Arguably, the ease with which milk can be processed to be more edible makes the rise of lactase persistence even more puzzling.

This result supports the role of selection in the evolution of lactase persistence, ruling out possible confounding effects from recombination suppression and population history.
