The hierarchy of biological classification's eight major taxonomic ranks, which is an example of definition by genus and differentia. A kingdom contains one or more phyla. Intermediate minor rankings are not shown.

In biology, a phylum (English pronunciation: /ˈfaɪləm/; plural: phyla)^{[note 1]} is a taxonomic rank below kingdom and above class. "Phylum" is equivalent to the botanical term division.^[1] The kingdom Animalia contains approximately 35 phyla; the kingdom Plantae contains 12 divisions. Current research in phylogenetics is uncovering the relationships between phyla, which are contained in larger clades, like Ecdysozoa and Embryophyta.

General description and familiar examples[link]

Informally, phyla can be thought of as grouping organisms based on general specialization of body plan,^[2] At the most basic level, a phylum can be defined in two ways: as a group of organisms with a certain degree of morphological or developmental similarity (the phenetic definition), or a group of organisms with a certain degree of evolutionary relatedness (the phylogenetic definition).^[3] Attempting to define a level of the Linnean hierarchy without referring to (evolutionary) relatedness is an unsatisfactory approach, but the phenetic definition is more useful when addressing questions of a morphological nature—such as how successful different body plans were.

Definition based on genetic relation[link]

The largest objective measure in the above definitions is the "certain degree"—how unrelated do organisms need to be to be members of different phyla? The minimal requirement is that all organisms in a phylum should be related closely enough for them to be clearly more closely related to one another than to any other group.^[3] However, even this is problematic, as the requirement depends on our current knowledge about organisms' relationships: As more data becomes available, particularly from molecular studies, we are better able to judge the relationships between groups. So phyla can be merged or split if it becomes apparent that they are related to one another or not. For example, the bearded worms were described as a new phylum (the Pogonophora) when described in 1914, but molecular work almost a century later found them closely related to annelids and merged the phyla, so that the bearded worms are now an annelid family.^[4] Likewise, the highly parasitic phylum Mesozoa was divided into two phyla Orthonectida and Rhombozoa, when it was discovered the Orthonectida are deuterostomes and the Rhombozoa protostomes.^[5]

This changeability of phyla has led some biologists to call for the concept of a phylum to be abandoned in favour of cladistics, a method in which plan" based definition of a phylum has been proposed by paleontologists Graham Budd and Sören Jensen. The definition was posited by paleontologists because extinct organisms are typically hardest to classify; they can be off-shoots that diverged from a phylum's line before the characters that define the modern phylum were all acquired.

Definition based on body plan[link]

By Budd and Jensen's definition, phyla are defined by a set of characters shared by all their living representatives. This has a couple of small problems—for instance, characters common to most members of a phylum may be secondarily lost by some members. It is also defined based on an arbitrary point of time (the present). However, as it is character based, it is easy to apply to the fossil record. A more major problem is that it relies on an objective decision of which group of organisms should be considered a phylum.

Its utility is that it makes it easy to classify extinct organisms as "stem groups" to the phyla with which they bear the most resemblance, based only on the taxonomically important similarities.^[3] However, proving that a fossil belongs to the crown group of a phylum is difficult, as it must display a character unique to a sub-set of the crown group.^[3] Furthermore, organisms in the stem group of a phylum can possess the "body plan" of the phylum without all the characteristics necessary to fall within it. This weakens the idea that each of the phyla represents a distinct body plan.^[6]

Based upon this definition, which some say is unreasonably affected by the chance survival of rare groups, which vastly increase the size of phyla, representatives of many modern phyla did not appear until long after the Cambrian.^[7]

Nate Ruess Andrew Dost Jack Antonoff

Fun (often stylized as fun.) is an American alternative rock band based in New York City that was formed by Nate Ruess, formerly of The Format. After the 2008 breakup of The Format, Ruess formed Fun with Andrew Dost and Jack Antonoff of Anathallo and Steel Train respectively.^[2] Fun has released two albums: their debut Aim and Ignite in 2009 and their latest Some Nights in February 2012.

The band is best known for its hit single "We Are Young" featuring Janelle Monáe. "We Are Young" reached number one on the U.S. Billboard Hot 100 and Digital Songs charts, becoming the first alternative song to top the Billboard Hot 100 chart since Coldplay's "Viva la Vida" in 2008. It also peaked at number one on the UK Singles Chart.

History[link]

2007–2008: Career beginning and formation[link]

The Format split in February 2008. Immediately afterward Nate Ruess asked Andrew Dost and Jack Antonoff to join his new project. Dost had toured with The Format and provided various instrumentation. Ruess met Antonoff after The Format toured with Steel Train.^[3] The three began working together in New Jersey within a week. Ruess sang melodies while the other two provided music for them.^[4] The first demo song the band recorded was "Benson Hedges," which was made available for free in Spin's September 20, 2008 article on the band.^[5] Fun approached Steven McDonald, who produced The Format's album Dog Problems with Ruess, to produce their debut album. McDonald was enthusiastic about the project and stated, "I can’t believe what we’re working on here. This crushes anything I’ve ever done."^[4]

[edit] 2009–2010: Aim and Ignite

Recording took place in the fall of 2008. The band's first single, "At Least I'm Not as Sad (As I Used to Be)" was made available as a free download on the band's Myspace page on April 6, 2009.^[6] Aim and Ignite was released on August 25, 2009 and had positive reviews. AbsolutePunk.net's Drew Beringer praised the album, stating it was "what a pop album 'should' sound like" and "the most essential pop album of 2009."^[7] Allmusic called the album "progressive, but in the best possible way" and admired Ruess's lyrics for "investigating the larger truths of life...with a witty approach that keeps the songs bubbling merrily along on a positive note".^[8] Dave de Sylvia of Sputnikmusic wrote, "Aim and Ignite isn’t the most consistent pop album around," but he ultimately commended the album as "a superbly mixed and arranged album made by musicians who clearly understand the limits and potential of pop music".^[9] Estella Hung of PopMatters was less impressed with the album. She praised songs "Be Calm" and "The Gambler", but criticized the lyrics and production of the album's early tracks. Hung concluded that while Aim and Ignite is "pretty original to say the least", it "fails to live up to the Format’s last outing."^[10] Popdose's Ken Shane called the album "an interesting and unusual listen." Shane applauded the album's songwriting and said "many of the songs are really good," but he objected to the "cute" production, desiring to hear the band "in a more stripped-down form." He ended his review with: "I have a similar problem with Dr. Dog, a band that was recommended to me by a number of people. I think much of their recorded work is too fussed over, but when I saw them live and their sound was more stripped down out of necessity, emphasizing their powerful songwriting, I thought they were wonderful. Perhaps the same fate awaits me with Fun."^[11] The album reached number 26 on Sputnikmusic's top 50 albums of 2009. The album peaked at 71 on the US album charts.

Fun began its first North American tour on November 8, 2008 with Jack's Mannequin.^[12] The debut album Aim and Ignite was released on August 25, 2009.^[13] In reviewing the album, The Washington Post called some of the arrangements "theatrical, much like those on Panic! at the Disco's 2005 debut".^[14] In February 2010, Fun supported Jack's Mannequin on their headline tour, along with Vedera which was followed by their first UK appearances in March. Their current touring band also includes Will Noon, Rob Kroehler, Emily Moore, Nate Harold, and Jon "Jonny Thunder" Goldstein.^[15] In April 2010, Fun supported Paramore's headline tour. Other support for the tour includes Relient K and Harriet Ellis of Summer Beats.^[16] The band then embarked on a full UK tour in May. On August 4, 2010, Fun announced that they had signed with label Fueled by Ramen.^[17]

On August 14, 2010, it was announced via the Official Paramore Fan Club that Fun would be opening for Paramore on their November UK tour.^[18] In 2010 Fun's single, "Walking the Dog," was used in a commercial for the travel site Expedia.com.^[19] In 2010, Will Noon (formerly of Straylight Run) played drums with Fun on tour, according to Noon's Twitter page.^[20] To celebrate the Paramore UK tour and the band’s new single ‘Walking The Dog’, Hassle Records gave away a free download of an acoustic version of the track.^[21] On April 27, 2011, a video of the band performing a new song entitled "Carry On" was uploaded to YouTube.^[22]

[edit] 2011–present: Some Nights

This section is in a list format that may be better presented using prose. You can help by converting this section to prose, if appropriate. Editing help is available. (April 2012)

On May 17, 2011, the band released "C'mon" as a joint single with Panic! at the Disco, who they opened for on their 2011 Vices & Virtues Tour.

On November 7, 2011, the band announced that their next album would be titled Some Nights and released on February 21, 2012. Its first single, called "We Are Young" and featuring Janelle Monáe, has since been used in several other media including:

• Gossip Girl season 5 episode 24 "The Return of the Ring"
• 90210 season 4 episode 24 "Forever Hold Your Peace"
• Glee episode "Hold On to Sixteen"
• introducing the Game Changer of the Year at the 2011 WWE Slammy Awards
• Chuck episode "Chuck Versus the Baby"
• Chevrolet Chevy Sonic Super Bowl XLVI commercial "Stunt Anthem", also featuring American professional skateboarder Rob Dyrdek and the rock band OK Go.^[23]
• a vignette promoting the WWE Wrestlemania XXVIII Main event match between John Cena and The Rock
• BBC Radio One as Scott Mills' Big Thing
• The trailer for the Judd Apatow film This is 40

On December 12, 2011, the band's song "One Foot" was available for instant streaming and free download on Nylon's website.^[24]

On February 13, 2012, the band released an album stream on their website along with a note from Ruess thanking fans for their ongoing support. Ruess states he is "over the moon about what you're about to hear and falling asleep knowing that as soon as I wake up, this will no longer be a dream."^[25]

On March 7, 2012, Fun's single "We Are Young" reached the No. 1 spot on the Billboard Hot 100 chart. This makes Fun the first multi-member rock band to have a #1 Billboard debut on the Hot 100 since Nickelback's "How You Remind Me" in December 2001/January 2002.^[26] On the same day, "We Are Young" was used by Apple in a promotional video of their recent retail development in Grand Central Terminal.^[27] On April 11, 2012, Billboard.com announced that Fun's "We Are Young" also made Digital Sales history. As the song was at the #1 spot on the Billboard Hot 100 for a sixth consecutive week, it has become the first, and at this time only, song that has ever gained 300,000+ downloads for seven weeks straight.^[28]

On March 19, 2012, Fun was announced as a performing band at the Bonnaroo 2012 music festival.

On June 3, 2012, Fun will perform "We Are Young" at the 2012 MTV Movie Awards.

"We Are Young" peaked at number 1 on May 27, 2012 in the UK.

Ryan Lewis (born March 25, 1988) is an American music producer, musician, music video director, photographer, graphic designer, rapper and DJ currently based in Seattle. He is best known for his collaboration with American rapper Macklemore (Ben Haggerty) producing Macklemore & Ryan Lewis — The VS. EP (2009), The Heist (2012) and a handful of other singles. Since the beginning of their collaboration in late 2008, Ryan has produced, recorded, engineered and mixed all of the music, directed music videos ("Same Love", "Thrift Shop", "And We Danced", "Otherside (Remix)"), designed visuals (album art, web design, posters) and DJed the live show.

In a recent mini-documentary, Lewis recalled meeting Macklemore for the first time. "When I met him, it was a really different time. It was less than a year after [2005's] Language of My World had come out. So he had buzz. For me being a young kid, it was very exciting to link with him. The bulk of our original relationship was photo shoots. I became kind of his photographer."^[1]

[edit] The Heist

On October 9, 2012, Macklemore & Ryan Lewis released The Heist. The album debuted at #2 on the Billboard charts and #1 on the Top R&B/Hip-Hop Albums and Top Rap Albums, selling 78,000 copies in the first week.^[2] The album also debuted at #1 on iTunes Digital Albums chart.^[3] The duo's album has received more than 1 million plays on SoundCloud, 70 million YouTube views and was accompanied by a sold-out 50-date U.S. and Canadian tour.^[4]
