Sentence examples for using the fossil node from inspiring English sources

Still aiming at testing hypotheses concerning life cycle evolution, we compared the likelihood of the reconstructions when several internal nodes were fixed to state (0) monoecious on herbs (using the "fossil node" command in Multistate) to the likelihood of the reconstructions when these same nodes were fixed to state (1) heteroecious.

The estimation of divergence time using the fossil as a crown-node constraint on Acilius suggested congruent ages for the basal nodes with relevant Gondwana break-up ages.

However, estimations using the fossil as an Acilius stem-node calibration dated the relevant nodes of the tree to be too young for some of these events.

The results were very similar compared to the difference of using the fossil on either the stem or crown node, why only the lognormal and the node of calibration will be discussed further.

Using the fossil calibration as an Acilius stem-node constraint gave significantly younger ages not congruent with Gondwana vicariance events.

The split between ancestral Eretini (optimized to Australian region) and ancestral Aciliini (optimized to S. America and Africa) would follow such a pattern and the age using the fossil calibration on the Acilius crown-node was estimated to an interval encompassing that geological age: 95% HPD = 138-88 Ma.

The ages inferred with the two calibrations differ little even for the hummingbird crown age (the deepest node), which is 24 (20.9-28.1) my using the fossil calibration or 25 (23 27) my using the rate calibration.

The prior on times was constructed using the fossil calibrations combined with the birth-death process [ 50] with parameters λ = μ = 1, ρ = 0 (representing a uniform distribution of node ages given the root age).

The second method uses the fossil record.

We used the fossils to calibrate molecular dating, the stem node of legumes hypothetically at 60 Ma in molecular dating as previous molecular research [ 34].

We carried out all analyses on both the fossil-node and fossil-tip calibrated MCCT trees with the outgroups pruned from the MCCT trees prior to analysis.
