The Callitrichidae are a family of New World monkeys, including marmosets and lion tamarins. At times, this group of animals has been regarded as a subfamily, called Callitrichinae, of the family Cebidae; this taxon was traditionally thought to be a primitive lineage, from which all the larger-bodied platyrrhines evolved. However, some works argue that callitrichids are a dwarfed lineage. Ancestral stem-callitrichids were "normal-sized" ceboids that were dwarfed through evolutionary time; this may exemplify a rare example of insular dwarfing in a mainland context, with the "islands" being formed by biogeographic barriers during arid climatic periods when forest distribution became patchy, and/or by the extensive river networks in the Amazon Basin. All callitrichids are arboreal, they are the smallest of the simian primates. They eat insects and the sap or gum from trees; the marmosets rely quite on tree exudates, with some species considered obligate exudativores. Callitrichids live in small, territorial groups of about five or six animals.

Their social organization is unique among primates and is called a "cooperative polyandrous group". This communal breeding system involves groups of multiple males and females, but only one female is reproductively active. Females mate with each shares the responsibility of carrying the offspring, they are the only primate group that produces twins, which constitute over 80% of births in species that have been studied. Unlike other male primates, male callitrichids provide as much parental care as females. Parental duties may include carrying, feeding and engaging in play behavior with offspring. In some cases, such as in the cotton-top tamarin, males those that are paternal, will show a greater involvement in caregiving than females; the typical social structure seems to constitute a breeding group, with several of their previous offspring living in the group and providing significant help in rearing the young.

Nativity: A Life Story is an African American Christmas-themed musical based on the Black Nativity written by Langston Hughes, intended to become a holiday tradition, appearing annually in various venues in New York City since its inception in the mid-1990s. The performances have been sponsored by the Schomburg Center for Research in Black Culture. Bruce Weber of The New York Times called it "a quirky combination of spiritual fervor, showbiz glamour, African-American pride and a celebration of women". Created in the mid-1990s, performances were held in a variety of auditoriums in New York City. In 2001, the musical was performed at Riverside Church, where crowds were in excess of the church's capacity of 1,900. Starting in 2002, Nativity found a home at the United Palace Theater, a venue owned by Reverend Ike and the United Christian Evangelistic Association located at 175th Street and Broadway in Washington Heights, Manhattan that provides seating for 3,500 for the three performances presented that year.

Howard Dodson announced at the time. The show was created by Harold Wheeler and Hattie Winston, together with producer James Stovall, executive director of the Ministry of the Arts & Culture at the Palace Theater. "Black Nativity", a gospel song-play by Langston Hughes first performed in 1961, was a major inspiration for Nativity. The show's producers planned for the show to become an annual tradition to rival the Christmas show at Radio City Music Hall and A Christmas Carol at the Theater at Madison Square Garden, though Weber in his 2002 review felt it "doesn't yet have the polish of its downtown cousins"; the 2002 production of Nativity featured a cast accompanied by three choirs and a company that totaled 125 performers. Several of the performers had appeared in Nativity in several previous year's productions, with Ebony Jo-Ann and Lillias White having contract clauses written into their agreements to perform elsewhere guaranteeing that they would be allowed to perform in Nativity. White, who performed the spiritual "No Room" said that "This is something I have to do every year".

BeBe Winans, who played Joseph, Stephanie Mills as Mary did a duet of Joseph Joubert's "Love Is a Miracle". The song "Have You Heard About the Baby" was performed by an a cappella trio led by Freddie Jackson. Composer William L. Dawson's hymn "Behold the Star" was led by Priscilla Baskerville together with the Ebony Ecumenical Ensemble and the Broadway Inspirational Voices. Narration was provided by Keith David and Phylicia Rashad; the closing number is "Spread the Word", described as "a rollicking gospel chorale" that had "the audience was on its feet and roaring as though a rock concert was ending" serving as "a fitting conclusion to this grandly spirited and wholly contemporary show, whose creators have persevered with a faith of their own". A 2003 review recognized the "powerful singing voices" and "dance that delivers the goose bumps", but said that "the production values are reminiscent of an elementary-school pageant, rickety scenery and all". Two performances of Nativity were presented in December 2006 at the nightclub Joe's Pub, featuring George Faison and Lillias White

Angel and Apostle is a novel written by Deborah Noyes and published in 2005.

Mag - the servant of Pearl and Nehemiah in London who had an affair with Nehemiah. Mary Whippe of mostlyfiction.com gave a positive review, saying "Noyes imbues her debut novel with energy and literary weight, continuing Pearl's story while remaining faithful to the original which inspired it. Her ability to include period detail and to reproduce the religious beliefs and practices of the period give additional credence to her story, the character of Pearl is free-spirited enough to strike a chord with modern readers" and finished by saying "pacing parallels that of Hawthorne, her exploration of behavior as a series of good acts or acts inspired by the Devil is consistent with his. Lovers of literary novels will admire Noyes's thoughtful reconstruction of its beliefs, her care in reproducing the language and style of the period are extraordinary, her development of the character of Pearl shows the emotional tensions inherent in a life lived under a theocracy".

Jill Grinberg of Publisher Weekly complimented the book by saying "engages with atmospheric charms of time an
