Australian multicellular fossils point to life on land, not at sea, geologist proposes

Ancient multicellular fossils long thought to be ancestors of early marine life are remnants of land-dwelling lichen or other microbial colonies, says University of Oregon scientist Gregory J. Retallack, who has been studying fossil soils of South Australia.

Ediacaran (pronounced EDI-akran) fossils date to 542-635 million years ago. They've been considered fossil jellyfish, worms and sea pens, but are preserved in ways distinct from marine invertebrate fossils. The fossils -- first discovered in 1946 in...

 The first unequivocal evidence that humans in prehistoric Northern Europe made cheese more than 7,000 years ago is described in research by an international team of scientists, led by the University of Bristol, published December 12 in Nature.

Algal ancestor is key to how deadly pathogens proliferate, researchers find

  • PDF
Apicomplexa are the parasites that cause malaria and toxoplasmosis. Researchers have discovered how an important structure inside these parasitic cells allows the cells to replicate and spread inside their hosts.

Over the summer a team of faculty and students from University of Kentucky discovered evidence of not just one lost community, but two in northern Italy. Using their archaeological expertise and modern technology, data was collected indicating the existence of a Roman settlement and below that, a...

From fish to human: Research reveals how fins became legs

  • PDF
Vertebrates' transition to living on land, instead of only in water, represented a major event in the history of life. Now, researchers reporting in the December issue of the Cell Press journal Developmental Cell provide new evidence that the development of hands and feet occurred through the gain of new DNA elements that activate particular genes.

 

"First, and foremost, this finding helps us to understand the power that the modification of gene expression has on shaping our...

Tracking gene flow in marine plant evolution

  • PDF
A new method that could give a deeper insight into evolutionary biology by tracing directionality in gene migration has just appeared in EPJ Data Science. Paolo Masucci from the Centre for Advanced Spatial Analysis, at University College of London, UK, and colleagues identified the segregation of genes that a marine plant underwent during its evolution. They found that the exchange of genes, or gene flow, between populations of a marine plant went westward from the Mediterranean to the...

Monkey business: What howler monkeys can tell us about the role of interbreeding in human evolution

Did different species of early humans interbreed and produce offspring of mixed ancestry?

Recent genetic studies suggest that Neanderthals may have bred with anatomically modern humans tens of thousands of years ago in the Middle East, contributing to the modern human gene pool. But the findings are not universally accepted, and the fossil record has not helped to clarify the role of interbreeding...
