How does multicellularity evolve? Scientists who study a family of green algae that includes unicellular Chlamydomonas and multicellular Volvox are beginning to find answers to this question.

Challenge students to answer this question: Unicellular organisms have the ability to mutate. How does this mutation in a unicellular organism affect the population compared to multicellular organisms ...

The first life forms to appear on Earth were unicellular, i.e., composed of a single cell, such as yeast or bacteria. Later, ...

Although some lineages or clades are entirely unicellular or multicellular (e.g., lobose amoeba and the land plants, respectively), most contain a mixture of body plans such as the unicellular and ...

In 2017, researchers discovered Chromosphaera perkinsii, a single-celled organism, in marine sediments in Hawaii. According to scientists from the University of Geneva, this organism can form ...

“Our findings show that the genetic underpinnings of cell-to-cell cohesion and segregation—the ability for different cells to sort themselves into separate regions within a multicellular mass—existed ...

Scientists study ancient unicellular organism C. perkinsii to understand transition from single-cell to multicellular life. Research suggests C. perkinsii demonstrates early forms of multicellular ...
