Published Scientists reveal how seascapes of the ancient world shaped genetic structure of European populations
(via sciencedaily.com) Original source Scientists have explored the importance of sea travel in prehistory by examining the genomes of ancient Maltese humans and comparing these with the genomes of this period from across Europe. Previous findings from the archaeological team had suggested that towards the end of the third millennium BC the use of the Maltese temples declined. Now, using genetic data from ancient Maltese individuals the current interdisciplinary research team has suggested a potential contributing cause. Researchers found that these ancient humans lacked some of the signatures of genetic changes that swept across Europe in this period, because of their island separation. Scientists concluded that physical topography, in particular seascapes played a central role as barriers to genetic exchange.
Published Ancient tooth unlocks mystery of Denisovans in Asia
(via sciencedaily.com) Original source What links a finger bone and some fossil teeth found in a cave in the remote Altai Mountains of Siberia to a single tooth found in a cave in the limestone landscapes of tropical Laos? The answer to this question has been established by an international team of researchers from Laos, Europe, the US and Australia. The human tooth was chanced upon during an archaeological survey in a remote area of Laos. The scientists have shown it originated from the same ancient human population first recognised in Denisova Cave (dubbed the Denisovans), in the Altai Mountains of Siberia (Russia).
