In research that could shed light on the growth and formation of complex tissue architectures, Brown University engineers ...

Prokaryotic single-celled organisms, the ancestors of modern-day bacteria and archaea, are the most ancient form of life on our planet, first appearing roughly 3.5 billion years ago. The first ...

A new idea about the origin of complex life turns current theories inside out. Scientists explain their 'inside-out' theory of how eukaryotic cells, which all multicellular life -- including us -- are ...

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 ...

Every living organism falls into one of two groups: eukaryotes or prokaryotes, with cellular structure determining which group an organism belongs to. Prokaryotes are unicellular and lack a nucleus ...

Space to play or pause, M to mute, left and right arrows to seek, up and down arrows for volume. Eukaryotes developed in a world markedly changed from earlier times.Early prokaryotes, over some 2 ...

The cell is the structural and functional unit of all living organisms, and is sometimes called the "building block of life." Some organisms, such as bacteria, are unicellular, consisting of a single ...

In this video we will get to learn about the differences between the unicellular and multicellular organisms. Also, we will get to know about the plant cell and animal cell. Different types of cells ...

The oldest ever fossils of a multicellular organism have been discovered - and are 200 million years older than any previous find. The 250 specimens were alive and living in shallow water 2.1 billion ...
