An unexpectedly long history of sexual selection in birds-of-paradise

Table 3 Rates of diversification.

Clade	Nummer of species	Age	Diversification rates (ε = 0)	Diversification rates (ε = 0.90)	Expected number of species (ε = 0)	Expected number of species (ε = 0.90)
Birds-of-paradise	40	23.8	0,13	0,06	2-131	4-455
core birds-of-paradise	34	15.1	0,19	0,09	1-35	2-156
Monarchidae	~130	~10.6	~0,39	~0,24	~1-17	~1-83
Dicuridae	~24	~20.0	~0,12	~0,06	~2-74	~3-290
core Corvoidae	755	39.5	0,15	0,11	11-1402	19-2658

Absolute rate of diversification for the entire birds-of-paradise clade, core (polygynous) birds-of-paradise, some closely related families, and core Corvoidea, estimated in absence of extinction (ε = 0) and comparatively high (ε = 0.90) relative extinction rate. The 95% confidence intervals at relative extinction rates of ε = 0 and ε = 0.90 are expressed as expected number of species for each clade. The 95% confidence intervals have been calculated as described by Magallon and Sanderson [Magallon and Sanderson 2001] and is based mean diversification rate for the core Corvoidea (at a relative extinction rates of ε = 0 and ε = 0.90) and the age of the clades.
