The arctic tern carries out the longest migration of any creature on Earth a journey of more than 36,000 kilometres (or 22,000 miles) from the Arctic to the Antarctic and back again, each year!

Massive ancient gas release gave evolution a push, evidence
shows Recent evidence has been found to support the
theory that 55 million years ago earth warming was caused in a
relatively rapid amount of time by methane releases from the ocean.
The release of methane is thought to have contributed to the
release of massive amounts of carbon dioxide into the atmosphere,
thereby setting off global warming. The warming trend that this set
off opened up new migration routes to animals and led to rapid
evolution of the more advanced species. The first primates, for
instance, appeared during this period. The authors of the research
article, printed in the journal 'Science', suggest that this
ancient global warming led to primitive animals dispersing across
the world and also evolving into more modern species.
