In summary, some moss species might be 40 80 MY old, whereas some genera might even be 80 100 MY old [ 6], which is also seconded by recent phylogenetic analyses [ 9, 10].
Eric Knox (personal communication) has such plans for several lobeliad genera and my colleagues and I hope to sequence plastomes for representatives of all Hawaiian genera in the immediate future.
Similarly, the 16.3 my crown age of the oldest temperate South American food-plant clade more or less matches the stem ages of the genera Sephanoides, 15.1 my, and Patagona, 15.8 my (Figs. 2 and Additional file 1: S1a).
Our analyses suggest that many harpaline tribes probably originated ~80 My ago with most of the extant genera evolving 25 - 40 My ago.
The proposed leporid phylogeny estimates that the Lepus lineage diverged 12.80 My ago from the Oryctolagus/Sylvilagus clade, and that the Sylvilagus and Oryctolagus genera diverged 10 My ago [ 41, 42].
I still maintain that a shed is a man's domain, and until I figure out what manly aspect of horticulture provides harmony between all genders, genera and species, my shed's flower box will remain unfilled.
Cicer is diverging from these two genera for about 27 MY.
In my study area, native plants from genera such as Atriplex, Eremophila, Dodonaea and the family Amaranthaceae (e.g. chenopods) should be considered for decoy crops.
From this tree, we used the phydist function in the R package Picante (Kembel et al. #b 500) to calculate pairwise phylogenetic distances in My for each pair of plant host genera (given as time of independent evolution, which is twice the time to most recent common ancestor).
Comparing Oryctolagus with other leporid genera that diverged about 12 My ago, the nucleotide differences throughout the gene occurred primarily around 0.00-0.10 0.00-0.100.05 nucleotide replandments per site for Lepus and Sylvilagus species, respectively.
