Large-scale genetic changes that marked the evolution of pregnancy in mammals have been identified by an international team of scientists. They found thousands of genes that evolved to be expressed in the uterus in early mammals. Surprisingly, these genes appear to have been recruited from other tissue types by transposons -- ancient mobile genetic elements sometimes thought of as genomic parasites. The study sheds light on how organisms evolve new morphological structures and functions.
A skull provides direct anatomical evidence that fills a problematic time gap of modern human migration into Europe. It is also the first proof that anatomically modern humans existed at the same time as Neanderthals in the same geographical area.
