Non-ultrametric phylogenetic trees shed new light on Neanderthal introgression

期刊: ORGANISMS DIVERSITY & EVOLUTION, 2023; 23 (4)

Ultrametric spaces are widely used to depict evolutionary times in phylogenetic trees since they assume that every population/species is located at th......

The Macrobiotus persimilis-polonicus complex (Eutardigrada, Macrobiotidae), another example of problematic species identification, with the description of four new species

期刊: ORGANISMS DIVERSITY & EVOLUTION, 2023; 23 (2)
