The Moon, African genes in Europe, and the Rift.

28 Mar 2012

A paper in Nature Geoscience, March 26th - see - claims the composition of the Moon is much like that of the Earth for it to have an origin outside elsewhere.

At ... there have been major movements of population between Africa and Europe over thousands of years, and not just recently. For example, during the Roman Empire, or as a result of the Arab wars of conquest, and the slave trade (when the Barbary coast pirates made slaving raids as far north as Cornwall and Ireland as well as the European slave trade in the 18th century). Genetic evidence suggests gene flow goes back all the way through to the early Holocene, a constant exchanges of peoples - even with sub-Sahara Africa.

At ... another article from Nature Geoscience - a relook at Africa's Rift Valley and how old the features might be. Predictably, they are older than expected, going back 25 million years.

Also aat ... news of research and an expedition to the Atlantis Massif, an undersea mountain complex near the Mid Ocean Ridge that has formed in a geologically recent time period, less than one million years ago.
