Accuracy of ancestral state reconstruction for non-neutral traits [PDF]
The assumptions underpinning ancestral state reconstruction are violated in many evolutionary systems, especially for traits under directional selection. However, the accuracy of ancestral state reconstruction for non-neutral traits is poorly understood.

Optimized ancestral state reconstruction using Sankoff parsimony [PDF]
Background Parsimony methods are widely used in molecular evolution to estimate the most plausible phylogeny for a set of characters. Sankoff parsimony determines the minimum number of changes required in a given phylogeny when a cost is associated to ...

WARACS: Wrappers to Automate the Reconstruction of Ancestral Character States [PDF]
Premise of the study: Reconstructions of ancestral character states are among the most widely used analyses for evaluating the morphological, cytological, or ecological evolution of an organismic lineage.

Choosing the best ancestral character state reconstruction method [PDF]
Despite its intrinsic difficulty, ancestral character state reconstruction is an essential tool for testing evolutionary hypothesis. Two major classes of approaches to this question can be distinguished: parsimony- or likelihood-based approaches.

Evidence for a Syncytial Origin of Eukaryotes from Ancestral State Reconstruction. [PDF]
AbstractModern accounts of eukaryogenesis entail an endosymbiotic encounter between an archaeal host and a proteobacterial endosymbiont, with subsequent evolution giving rise to a unicell possessing a single nucleus and mitochondria. The mononucleate state of the last eukaryotic common ancestor (LECA) is seldom, if ever, questioned, even though cells ...

Evolutionary insights into Felidae iris color through ancestral state reconstruction. [PDF]
Summary There have been almost no studies with an evolutionary perspective on eye (iris) color, outside of humans and domesticated animals. Extant members of the family Felidae have a great interspecific and intraspecific diversity of eye colors, in stark contrast to their closest relatives, all of which have only brown eyes. This makes

Morphological character evolution and ancestral state reconstruction in phylactolaemate bryozoans [PDF]
Phylactolaemates represent a small clade within bryozoans that exclusively occur in limnic habitats. About 100 species are described in seven to eight families.

Ancestral state reconstruction of metabolic pathways across pangenome ensembles. [PDF]
As genome sequencing efforts are unveiling the genetic diversity of the biosphere with an unprecedented speed, there is a need to accurately describe the structural and functional properties of groups of extant species whose genomes have been sequenced, as well as their inferred ancestors, at any given taxonomic level of their phylogeny.

Evolutionary Origin of Prolonged Delayed Fertilization in the Fagaceae [PDF]
The temporal organization of flowering, fertilization, and fruiting is a fundamental axis of life‐history evolution in angiosperms. While most species complete fruit development within a single growing season (“1‐year fruiting”), many Fagaceae species ...
