Queuing is nothing new reveals a study, showing that primitive early creatures were forming an orderly line 480 million years ago.
Scientists say that the fossils of ancient arthropods discovered in linear formation in Morocco may indicate a 'collective behaviour' either in response to environmental cues or as part of seasonal reproductive migration.
Findings - Journal - Scientific - Reports - Group
Their findings, published in the journal Scientific Reports, suggest that group behaviour comparable to modern animals existed as early as 480 million years ago.
Dr Jean Vannier explained that collective and social behaviour is known to have evolved through natural selection over millions of years.

He said modern arthropods provide numerous examples, such as the migratory chains of caterpillars, ants or spiny lobsters.
But the origins and early history of collective behaviour has remained largely unknown.
Dr - Vannier - Colleagues - Clusters - Ampyx
Dr Vannier and his colleagues described several linear clusters of Ampyx priscus, a trilobite arthropod from the lower Ordovician period, in modern day Morocco.
He said: 'The trilobites, which were between 16 and 22 millimetres long, had a stout spine at the front of their bodies and a pair of very long spines at the back.'

He said that In each cluster of trilobite fossils examined by his team, individuals were arranged in a line, with the front of their...
