Description
The classic birth-death model incorrectly assumes that if a speciation event took place recently, the new species is directly recognized as a good species. Here I want to present the consequence of this often criticized and incorrect assumption. To do so, phylogenies are simulated using a protracted birth-death model, to serve as 'the truth' in nature. DNA alignments true to these phylogenies are generated, to serve as simulated field data. From that data, it is tried to infer the original phylogeny back again, using (one of) the tools already present. The tool chosen is BEAST2, a Bayesian inference tool, for which a standard birth-death model tree prior was set up. Using BEAST2, from the simulated field data, a posterior is inferred and the error between original phylogeny and posterior is quantified with the normalized lineages-through-time statistic. The results indicate that the error made increases with the duration of speciation.| Period | 15-Feb-2017 |
