Minimum spanning tree (MST) algorithms can generate multiple, equally-minimal, MSTs but MST programs typically report only one, arbitrarily chosen MST. Similarly, most MST programs do not provide statistical metrics to support the credibility of the MSTs that they estimate. MSTgold estimates the number of alternative MSTs, reports up to a user-determined number of those trees, reports a consensus tree, and implements a bootstrapping metric to assess the reliability of alternate MST solutions. ...

Controversial ideas of Williamson, Margulis & others suggest speciation by hybridizing might be more common than originally thought. Taking this concept to the nth degree & assuming that indeed, speciation mostly occurs by hybridizing events, not the accumulation of mutations or genetic drift, here is a catalogueoflife2gedcom converter. It allows the tree of life to be displayed as a human genealogy tree with hybridizing events depicted as "marriages." The idea then is that mutation...

A PHP webapp to upload taxonomic checklists as Excel or CSV files to be served as TDWG TCS XML/RDF. It can handle multiple checklists, has a Tapir light webservice and a taxonomic tree of species names created from taxonomy in a checklist can be browsed.
