One of the outstanding figures in a Copper Age Iberian society was feminine, not male as initially thought, in response to molecular evaluation of their enamel.

The Iberian Copper Age dates again to roughly 4000 to 5000 years in the past and is marked by the emergence of copper smelting in what’s now Spain and Portugal.

In 2008, archaeologists at Valencina in south-west Spain – one of many largest Copper Age websites in Europe – unearthed the stays of a person whose tomb was adorned with lavish items, equivalent to an ornate rock crystal dagger and ivory objects together with an African elephant tusk.

They have been additionally buried alone, in contrast to most individuals on the time. “This means that the person was most likely the best standing of their time within the Iberian peninsula and even western Europe,” says Leonardo García Sanjuán on the College of Seville in Spain.

Based mostly on an evaluation of the skeleton when it was first uncovered, researchers deduced that this particular person was most likely male and was between 17 and 25 years previous.

However García Sanjuán and his colleagues have now decided that the determine was in truth feminine, based mostly on a protein referred to as amelogenin present in tooth enamel. Amelogenin is encoded by two genes referred to as AMELX and AMELY, that are discovered on the X and Y chromosomes respectively. Folks produce totally different variations of amelogenin relying on which intercourse chromosomes they’ve, so evaluation of the protein can reveal somebody’s intercourse.

García Sanjuán and his crew have dubbed her the “Ivory Girl”. The burial websites of youngsters from this period don’t characteristic treasured objects, suggesting that inheritance of wealth wasn’t widespread on this society and social standing wasn’t ascribed by beginning. The researchers due to this fact speculate that she should have earned her excessive rank.

The findings counsel that ladies might have performed a way more outstanding position in Iberian Copper Age societies than was beforehand identified, says García Sanjuán.

“This opens up totally new potentialities of analysis to know what the political and social position of girls was in these very complicated societies, which, frankly, we all know little or no about,” he says.
