Some single-celled organisms are known to transition to multicellularity during their lifetimes, usually either by cloning themselves or when many similar cells come together to form a larger ...

A globally distributed single-celled organism that occurs in harmful algal blooms has been found to exhibit an unusual organisation of photosynthesis. Researchers have taken a closer look at the ...

All life on Earth came from one common ancestor – a single-celled organism – but what it looked like, how it lived and how it evolved into today's modern cells is a four billion year old mystery being ...

Animals, from worms and sponges to jellyfish and whales, contain anywhere from a few thousand to tens of trillions of nearly genetically identical cells. Depending on the organism, these cells arrange ...

Add Yahoo as a preferred source to see more of our stories on Google. A light microscopy image shows the marine algae Braarudosphaera bigelowii, which is a potentially large evolutionary step. This ...

Too much of a good thing is no good at all. Living organisms enjoy sunlight -- in fact, many need it to stay alive -- but they tend to avoid light that is too bright. Animals go to their shelter, ...

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 ...
