  • A beautiful example of this paradigm is a single cell organism called ciliate – the gene assembly process in ciliates has turned out to be a very elegant computational process which even uses one of the basic data structures of computer science: the linked lists!

  • As these cells are small (about a micrometer across) the most likely consumers of Synechococcus or Prochlorococcus are flagellate and ciliate protists.

  • Similarly, among protists, a radiolarian may capture and ingest, more or less indifferently, a bacterium, an autotrophic flagellate, a herbivorous oligotrich ciliate, or another radiolarian (Fig 2E).
