While loop networks have long been used in architecture, their discovery in biology is credited to Uri Alon of the Weizmann Institute on Science. In 2002, Alon published a by entitled “Network motifs in the transcriptional regulation network of Escherichia coli” in the April edition of the journal Nature Genetics. These newly recognized loop networks, however, present new challenges to evolution.
