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 ...

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 ...

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 ...

The diversity of unicellular eukaryotes covered in the study, with their nucleus (blue) and microtubule cytoskeleton (magenta) stained. These organisms are so distantly related to each other as they ...

Researchers have discovered a mechanism steering the evolution of multicellular life. They identified how altered protein folding drives multicellular evolution. Researchers have discovered a ...

Shown are representatives of all major lineages of eukaryotic organisms, color coded for occurrence of multicellularity. Solid black circles indicate major lineages composed entirely of unicellular ...

Groundbreaking fossils unearthed in China suggest that multicellular organisms arose earlier than scientists previously thought. The fossils, of what may be an ancient type of photosynthetic alga, are ...

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 ...

“Animals are regarded as this very special branch, as in, there had to be so many innovations to be an animal,” David Booth, a biologist at the University of California, Berkeley, who wasn’t involved ...
