Line 1: − '''Migration''' is the movement of animals (particularly [[bird]]s) to live in another place.+ + + − With animals, migration is usually a periodic movement to better climate or feeding areas. It is typically repeated in a similar manner each year.+ + + + − == Animals ==+ + + + + + − Animal migration presents marvelous examples of good design: how do many creatures find their way to their destination?+ + + + + + − Each year, a few towns in [[California]] are greeted by the arrival of tens of thousands of [[monarch butterfly|monarch butterflies]]. [[Pacific Grove]], California, is the peculiar destination of a huge quantity of such butterflies each year.+ + − + − This report notes that one butterfly was tracked along a 1,870 mile route, from [[Ontario]] to [[Mexico]]. Its actual flight distance could easily have been two or even three times greater, because butterflies do not fly in straight lines.+ + + − How do the [[butterfly|butterflies]] navigate themselves? This ability has confounded scientists for a long time, although they now have some understanding of the incredible design features involved.+ − But the question remains: How did these creatures acquire this ability in the first place?+ + + − Materialistic explanations are inadequate.+ − In [[Theory of evolution|evolutionary]] terms, butterflies are merely [[insect]]s far less developed than [[human]]s. But most humans could not even [[navigation|navigate]], unaided, 1,870 miles to a certain destination.+ + + + + − Simply recounting migration illustrates its wonder:"<ref>http://www.si.edu/resource/faq/nmnh/buginfo/monarch.htm</ref>+ + + + + + − {{QuoteBox|There are 12 known pockets of [[forest]]s in Mexico where Monarchs gather for the winter. They have been seen in the [[Sierra Madre Mountains]] of Mexico by the tens of millions, and estimated at 4 million butterflies per acre. All wintering sites are about 9,000 feet in elevation, generally cold with [[frost]]s at times. ... The majority of Monarchs from the east side of the [[Rocky Mountains]] overwinter in Mexico, but those from west of the Rockies overwinter in groves of [[Monterey pines]] or [[eucalyptus]] trees at sites along the California coast, from [[San Francisco]] to [[Los Angeles]].}}+ − + − Even more remarkable is how many butterflies die during the migration, and yet their offspring continue on the same journey nevertheless.+ − + − + − == References == − {{reflist}} − − == See also == − * Poirier, Jules, [http://creationontheweb.com/content/view/763/ The magnificent migrating monarch] ''Creation'' 20(1):28–31, December 1997. − − [[category:zoology]]

A place where nobody dared to go
The love that we came to know
They call it Xanadu
And now
Open your eyes and see
What we have made is real
We are in Xanadu
A million lights are dancing
And there you are
A shooting star
An everlasting world
And you're here with me
Eternally
Xanadu, Xanadu,
(now we are here)
In Xanadu
Xanadu, Xanadu,
(now we are here)
In Xanadu
Xanadu, your neon lights will shine
For you, Xanadu
The [[PBS|Public Broadcasting Service]] provides a description of the phenomenon.<ref>http://www.pbs.org/wnet/nature/alienempire/voyagers.html</ref>
The love
The echoes of long ago
You needed the world to know
They are in Xanadu
The dream
That came through a million years
That lived on through all the tears
It came to Xanadu
A million lights are dancing
And there you are
A shooting star
An everlasting world
And you're here with me
Eternally
Xanadu, Xanadu,
(now we are here)
In Xanadu
Xanadu, Xanadu,
(now we are here)
In Xanadu
Now that I'm here
Now that you're near in Xanadu
Now that I'm here
Now that you're near in Xanadu
Xanadu...
