The oldest trace fossils of a multicellular organism's movement were found in 2.1-billion-year-old strata in Gabon. It is presumed to have moved in search of food. Photo courtesy of PNAS Fossilized ...
Scientists have discovered the fossil of what may be the earliest multicellular animal ever found. Dating back a billion years, the microscopic fossil contains two distinct cell types, potentially ...
Chromosphaera perkinsii is a single-celled species discovered in 2017 in marine sediments around Hawaii. The first signs of its presence on Earth have been dated at over a billion years, well before ...
A major event in the evolution of organisms on earth was the development of complex, multicellular life forms made of eukaryotic cells, which are thought to have come from prokaryotic cells. Studies ...
Over 3,000 generations of laboratory evolution, researchers watched as their model organism, 'snowflake yeast,' began to adapt as multicellular individuals. In new research, the team shows how ...
Images of the multicellular development of the ichthyosporean Chromosphaera perkinsii, a close cousin of animals. In red, the membranes and in blue the nuclei with their DNA. The image was obtained ...
A new study by researchers at the University of Queensland is calling old ideas about evolution into question. The scientists used powerful genetic technologies to sequence every gene being expressed ...
In a remarkable development, scientists at Tufts University and the University of Vermont have created a new biological organism that can self-replicate. The discovery builds on earlier work creating ...
