Based on coalescent theory, an approach to population genetics that uses genetic diversity to trace genealogies, Pybus developed calculations that generate approximate chronologies of viral epidemics.

The researchers also used something called coalescent modelling to figure out at what point the golden - crowned split off from its parental species.

We set up input parameters to values recommended by the developers (29): number of iterations = 25, maximum 2N0 coalescent time = 15, initial θ ∕ ρ = 5.

CoMuS: Simulating coalescent histories and polymorphic data from multiple species Papadantonakis, S., Poirazi, P., and Pavlidis, P. Molecular Ecology Resources, 2016.

We analyzed genetic (mitochondrial control region) and isotopic information from modern and prehistoric gray whales using serial coalescent simulations and Bayesian skyline analyses to test for a pre-whaling decline and to examine prehistoric genetic diversity, population dynamics and ecology.

As Colen progressed in the series, painting several iterations of the same animated frame, the image became successively less coalescent, the rendering more individuated and further from the idea of the perfectly blended oil painting.

Improving Bayesian population dynamics inference: A coalescent - based model for multiple loci

This is likely the first time that coarse - graining, a physics principle, and Λ - coalescents, a set of mathematical models, have been used to address questions in ecology.

Instead, they found another family of mathematical models, called Λ - coalescents, are better able to describe the unique patterns of diversification.

(a) Rarecoal tracks the probabilities for the lineages of rare alleles (red) within a coalescent framework back in time, and approximates the distribution of non-derived alleles (dark blue) by its average.

Both demographic simulations and coalescent analyses indicate that genetic data are consistent with a recent bottleneck and a pre-bottleneck size of > ca. 60,000.

Though our ability to infer what was surely a complex demographic history is limited by the number of ancient samples available and large uncertainties associated with the coalescent and evolutionary processes, these first ancient data for gray whales demonstrate the value of paired genetic and isotopic studies of ancient samples, showing that a population bottleneck can result in significant genetic differentiation between ancient and modern samples without requiring spatial structure.

Both a lognormal relaxed and strict clock were tested with a coalescent of constant size.
