Sentence examples for lineage rate from inspiring English sources

Using a date for the LV flock of 0.12 Myr based on the older, conservative calibration [27] would yield a staggering per lineage rate estimate of over 50 species/Myr.

Our results confirm previous theoretical work suggesting that observations of among lineage rate variation in empirical data may be due to the stochastic substitution process and error in the estimation of substitution rates, rather than true differences in the underlying substitution process among lineages.

We now consider two identical sequences, where one (note, this is a single lineage rate constant) is given the opportunity to diverge.

I will present our published RelTime method that estimates relative times of divergences for all branching points (nodes) in very large phylogenetic trees without assuming a specific model for lineage rate variation or specifying any clock calibrations.

However, several factors other than intrinsic problems with lineage rate variation and branch length estimation can produce overestimations of the molecular rate when dating nodes based on island ages [ 38].

The lineage rate estimates showed that D. sechellia had, in general, much higher δ than β (supplementary table S7, Supplementary Material online) and that the D. sechellia's δ estimates were also much higher than the δ estimates of the other species analyzed.

We used models assuming constant per lineage rates of speciation and extinction to estimate average net diversification rates (speciation rate minus extinction rate) for the LT flock and constituent clades (Table S2) [32].

The average estimate of the per lineage diversification rate for the entire LT endemic flock, assuming a root age of 12 Mya and a Yule Prior for the distribution of node ages, is 0.31 species/Myr (we report per lineage rates throughout).

RelTime is a useful method to estimate relative lineage-specific evolutionary rates and relative divergence times without requiring the pre-specification of statistical distribution of lineage rates and clock calibrations [ 22].

In summary, we suggest that estimates of among-lineage rate variation are prone to error.

A third issue in molecular dating involves the general modelling of among-lineage rate heterogeneity.
