Origin and global diversification patterns of tropical rain forests: inferences from a complete genus-level phylogeny of palms

Table 1 Mean estimated ages, 95% confidence intervals and ancestral ecologies for the family and subfamilies

Clade	Age in Ma	95% HPD	Proportional likelihoods of ancestral ecology of branch leading to node^a
Arecaceae, crown	100.1	92-108.7	0 = 0.984/1 = 0.0/2 = 0.0
Calamoideae, crown	80.2	70.3-90.3	0 = 0.999/1 = 0.0/2 = 0.0
Nypoideae, stem	93.5	87.5-100.6	0 = 0.982/1 = 0.0/2 = 0.0
Coryphoideae, crown	66.0	51.35-80	0 = 0.716/1 = 0.28/2 = 0.0
Ceroxyloideae, crown	52.1	30-74.2	0 = 0.979/1 = 0.0/2 = 0.0
Arecoideae, crown	73.6	66.1-81.3	0 = 0.999/1 = 0.0/2 = 0.0

Bold entries indicate values significantly different from other states.
^a0 = Tropical rain forest restricted; 1 = mangrove restricted; 2 = non-rain forest restricted.
HPD = highest posterior density; Ma = millions of years.
