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 ...

In the ocean, some protists function like plants, using light to manufacture their own food. Others, such as choanoflagellates, which are animals' closest living unicellular relatives, envelop and ...

How one protist spins and swims The protist Idionectes vortex was discovered in 2010, but only recently did scientists show that it moves via toroidal swimming. Its flagellum loops like a doughnut.

Life How did multicellular life evolve? Algae and yeast give some hints Single-celled organisms that cluster and cooperate provide tantalising insights into the origins of multicellularity ...

Meteora sporadica, a protist with incredible cell architecture, is related to Hemimastigophora. Current Biology, 2024; 34 (2): 451 DOI: 10.1016/j.cub.2023.12.032 ...

But, when researchers looked at the genetic code, the protist Oligohymenophorea sp. PL0344 turned out to be a novel species with an unlikely change in how its DNA is translated into proteins.
