To find clues, she has trained her sights on choanoflagellates — a group of single - celled eukaryotes thought to be the closest living relatives of animals.

Only later did eukaryotes say good - bye to their strange relatives and set off on their own evolutionary path.

Biochemist Radhey Gupta of McMaster University in Canada proposes that a bacterium and an archaean fused to form the first eukaryote, based on his analysis of a pair of slow - changing genes found in what may be one of the oldest cells with a nucleus, Giardia lamblia.

Most biologists typically recognize three official branches of life: the eukaryotes, which are organisms whose cells have a nucleus; bacteria, the single - celled organisms that may or may not possess a nucleus; and archaea, an ancient line of microbes without nuclei that may make up as much as a third of all life on Earth (See «Will the Methane Bubble Burst?»

The EBP would focus on the natural world, providing a better understanding of biodiversity by first sequencing in great detail the DNA of a member of each eukaryotic family (about 9000 in all) and eventually generating coarser genomes for the other eukaryotes.

(Eukaryotes, on the other hand, frequently harbor symbiotic bacteria.)

«I argue that the boring billion was the anvil on which the eukaryote cell was forged.

Based on pioneering work from the acclaimed biologist Carl Woese, it has been known that eukaryotes at some point shared a common ancestor with archaea.

One view of the Phylogeny of Life on Earth (at the University of California at Berkeley's Museum of Paleontology) highlights the role of archeabacteria among prokaryotes — as a separate «Archaea domain» apart from Eubacteria — in the development of cellular life with nuclei (eukaryotes).

The prokaryotic cells that were too small to be digested continued to live inside the host eukaryote, eventually becoming dependent on the host cell for organic molecules and inorganic compounds.

Although none of these organisms has yet been isolated, observed under the microscope nor cultured, these genome sequences provide us with an unprecedented opportunity to explore the origins of these cytoskeletal elements and promise to shed light on the evolutionary transition that led to the emergence of eukaryotes.

In eukaryotes, a homeobox encodes a protein domain (the homeodomain) which can bind DNA that act as part of transcription factors to switch on cascades of other genes that induce cellular differentiation by initiating the cascades of coregulated genes required to make individual tissues, organs, or body parts.
