22 apr 2022 · Phylogenies (evolutionary trees) have provided key insights into the international spread of SARS-CoV-2 and enabled investigation of individual outbreaks and transmission chains in specific...
18 mag 2020 · Deeper divergences pose a greater challenge to the inference of a gene tree as the phylogenetic signal erodes (that is, multiple mutations accumulate resulting in homoplasy) and the risk of...

Genes, Genealogies and Phylogenies. Controversy over human evolution remains widespread. However, the Human Genome Project and genetic sequencing of many other species have provided myriad precise and unambiguous genetic markers that establish our evolutionary relationships with other mammals.
24 feb 2023 · In the first case, one considers long-term evolution and compares mutations (including substitutions) that have been fixed between different species. The second case considers short-term evolution and concerns the study of variation that is still segregating in a population.
3 feb 2020 · Here, we demonstrate PhaME’s ability to construct robust genus and species phylogenies using examples that span the tree of life, with up to thousands of genomes as input in the form of raw ...

10 ago 2022 · Complete genomes reveal the full gene repertoire of an organism. Using fully sequenced genomes for orthology inference allows for a more confident assessment of gene histories by improving the detection of orthology and paralogy relationships, the estimation of gene gains and losses, and the detection of horizontal transfer events ...
5 ott 2015 · Morphology remains a powerful independent source of evidence for testing molecular clades, and — through fossil phenotypes — the primary means for time-scaling phylogenies. Morphological phylogenetics is therefore vital for transforming undated molecular topologies into dated evolutionary trees.
