0070 - Neolithic ditches and rectangular houses
Senhora da Alegria is a surprising and important site, by the combination of its location, structures and chronologies.
It is located in central Portugal, where the littoral platform gives way to the central mountains and in one of the pathways to the hinterland of Beira Alta central Portugal, where no ditched/palisade enclosures were known until now.
A sequence of occupations dating from Early Neolithic (with “cardial” decorated pottery) to Late Neolithic is being excavated by the Omniknos company (scientific coordination of António Valera and field direction of Tiago do Pereiro and Rui Ramos) in a context of archaeological emergency intervention.
The site presents several ditches, some of them probably corresponding to palisades, that form more than one enclosure, with several moments of construction with structures cutting other structures...

Lactase persistence in Neolithic Iberia
This is an extremely important study as it establishes the occurrence of lactase persistence in Neolithic Europe. This invalidates the idea proposed by some about a very late (post-Neolithic) introduction of lactase persistence into Europe by a pastoral population from the east, since we now have good evidence about the presence of this trait in a Neolithic sample from Atlantic Europe.
The frequency is higher than in the early Neolithic Linearbandkeramik (where it was absent in the tested samples), and lower than in present-day Basques, although levels of 27% are quite comparable to some modern south European populations. We are unlikely to detect the earliest occurrence of this trait (when it was limited to the original mutant and his descendants, prior to having a substantial advantage for digesting milk), but the new findings represent a new non-zero data point in the time series, which will certainly fill up as more points in space and time are tested.
