| One of the darker periods in Lagos’ history is the time when in the 15th century the town sported a market at which slaves, imported from North Africa, were sold on a market. The first African slaves entered post-medieval Europe through this small building that dates back to 1444 although most of it dates to 1691 by request of the 2nd Marquis of Niza, D. Francisco Luis da Gama, who built the Guards Mess over the building where the slaves used to be sold. |

Mitochondrial DNA analysis of Atlantic European samples has detected significant latitudinal clines for several clusters with Paleolithic (H) and Neolithic (J, U4, U5a1, and U5a1a) coalescence ages in Europe.
These gradients may be explained as the result of Neolithic influence on a rather homogeneous Paleolithic background.
There is also evidence that some Neolithic clusters reached this border by a continental route ( J, J1, J1a, U5a1, and U5a1a), whereas others (J2) did so through the Mediterranean coast.
An important gene flow from Africa was detected in the Atlantic Iberia.
Specific sub-Saharan lineages appeared mainly restricted to southern Portugal, and could be attributed to historic Black slave trade in the area and to a probable Saharan Neolithic influence.
In fact, U6 haplotypes of specific North African origin have only been detected in the Iberian peninsula northwards from central Portugal.
Based on this peculiar distribution and the high diversity _value (0.014 _ 0.001) in this area compared to North Africa (0.006 _ 0.001), we reject the proposal that only historic events such as the Moslem occupation are the main cause of this gene flow, and instead propose a pre-Neolithic origin for it.
