Analysis of DNA from a choanoflagellate, the closest known living nonanimal relative of animals, allows scientists to infer the genetic starter kit possessed by the first animal, the studies suggest.
In the new vision--based on increasingly sophisticated genetic analyses--people and other animals are closer cousins to single-celled choanoflagellates than to other multicellular organisms.
Recently, integrins and other components of the integrin-mediated adhesion and signalling machinery have been identified in unicellular organisms; such as in the filasterean Capsaspora owczarzaki, a close relative of metazoans and choanoflagellates.
Free-living, unicellular organisms called choanoflagellates, however, could be on every person's family tree, so long as it was a gigantic one.

In that scenario, colonies of single-celled organisms called choanoflagellates gave way to multicellular predecessors of sponges; millions of years later, an offshoot of these organisms formed nerve cells.
A study of choanoflagellates, which are unicellular protists that resemble the collar cells of sponges, suggests that they also have both these important tools.
