Sentence examples for molecular clock use from inspiring English sources

Bayesian estimations of divergence times that do not assume the molecular clock use time constraints at multiple nodes, usually based on the fossil records, as major boundary conditions.

However, uncertainty in the absolute age of the evolutionary event used to calibrate the molecular clock, use of different genes or genomic regions, and different methods to estimate divergence times contribute to the variation in divergence time estimates between species (Gaut 2002).

Fig. 2 This figure illustrates the "molecular clock" using the most parsimonious evolutionary reconstruction shown in Fig. 1a.

Neighbor, without a molecular clock using the W-curve matrix as input, places the sequences in the same clades.

It is likely that calibrating a molecular clock using these laboratory-passaged strains would also have detrimental effects on estimating tMRCAs.

To investigate whether rates of molecular evolution fit with a strict molecular clock model, the likelihood of the ML phylogeny was recalculated with the constraint of global molecular clock using the Rambaut parameterization for clock optimization implemented in PAUP4b10 [58].

It is possible that specific, small regions of Xist are evolving at different rates in each species but that this signal is lost in the total data set, so we also conducted the LRT of the molecular clock using a sliding window approach.

Simulations were run with a strict molecular clock using uniformly distributed priors.

a Specific molecular clock used for the estimation: 3.7 × 10-9 per site per year.

We present a new method for relaxing the assumption of a strict molecular clock using Markov chain Monte Carlo to implement Bayesian modeling averaging over random local molecular clocks.

Therefore, we had to use a secondary calibration strategy for the molecular clock using as calibration more distant outgroup taxa within Cyprinodontiformes [ 33].
