Millennium problems in phylogenetics
WebAbstract Mapping of mutations on a phylogeny has been a commonly used analytical tool in phylogenetics and molecular evolution. However, the common approaches for mapping mutations based on parsimony have lacked a solid statistical foundation. Here, I present a Bayesian method for mapping mutations on a phylogeny.

WebThe Poincaré conjecture problem was first proposed by French mathematician Henri Poincaré in 1904. The problem concerns the geometry of multidimensional spaces. The Poincaré Conjecture was considered to be one of the most famous unresolved problems in topology and mathematics. Webproblems a guaranteed worst-case performance exists, i.e. a formula that states that the solution found by the algorithm will be, for example, at most 10% from optimal. In phylogenetics, however, no such guarantee exists, especially for very large trees computed with Maximum Likelihood (ML). The NP-hardness of ML has recently been demonstrated …
Web2 dec. 2024 · The fourth assumption underpins them all and is so critical that, if you kick it out, the entire foundation of phylogenetics collapses. That assumption is that there is at least some form of common ancestry in the group that can be traced in the first place.
