The problem: Answer a question about this article:
A route through Beringia is seen as more likely than the Solutrean hypothesis. Kashani et al. 2012 state that "The similarities in ages and geographical distributions for C4c and the previously analyzed X2a lineage provide support to the scenario of a dual origin for Paleo-Indians. Taking into account that C4c is deeply rooted in the Asian portion of the mtDNA phylogeny and is indubitably of Asian origin, the finding that C4c and X2a are characterized by parallel genetic histories definitively dismisses the controversial hypothesis of an Atlantic glacial entry route into North America."
When did Kashani and others make their statement regarding the similarities for C4c distributions?

The answer: 2012

A report released in January 2011 by the Diario de Noticias and published in Portugal by Gradiva, had demonstrated that in the period between the Carnation Revolution in 1974 and 2010, the democratic Portuguese Republic governments encouraged over-expenditure and investment bubbles through unclear Publicprivate partnerships and funding of numerous ineffective and unnecessary external consultancy and advisory of committees and firms. This allowed considerable slippage in state-managed public works and inflated top management and head officer bonuses and wages. Persistent and lasting recruitment policies boosted the number of redundant public servants. Risky credit, public debt creation, and European structural and cohesion funds were mismanaged across almost four decades.
