The world is full of unusual unicellular organisms and microbes, many of which have not been discovered yet. In 2017, ...

The "boring billion" shaped multicellularity, with energy demands sparking complexity. This era shows evolution's cost.

Scientists have observed a type of cell division in a prehistoric unicellular organism that resembles the embryonic development seen in animal embryos, hinting that embryonic processes may have ...

A cell of the ichthyosporean C. perkinsii showing distinct signs of polarity, with clear cortical localization of the nucleus ...

Chromosphaera perkinsii, a billion-year-old species, may reveal multicellularity’s origins, predating the chicken and egg.

What came first, the chicken or the egg? If we’re talking about eggs in general, then the latter, but a new study of an ...

Between 1.8 billion and 800 million years ago, earthly life was in the doldrums. During this period, called the "boring ...

The first life forms to appear on Earth were unicellular, i.e. composed of a single cell, such as yeast or bacteria. Later, animals -- multicellular organisms -- evolved, developing from a single ...

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 ...
