The cat flea (Ctenocephalides felis) is the most common parasite of domestic cats and dogs worldwide. Due to the morphological ambiguity of C. felis and a lack of — particularly largescale — phylogenetic data, we do not know whether global C. felis populations are morphologically and genet...

Nevertheless, the compartmentalization was suggested sometime between 1656 and 1892, whereas the common ancestor of all modern American bat RABV lineages was aged to between 1254 and 1782 (Hughes et al., 2005). Monoclonal antibody (MAb) typing of virus isolates suggests that the most divergent ...
heterozygotes. While animals in the core family appeared to be closely related based upon pedigree analysis, and FXI-V516M segregated within the pedigree (Figure 2), a single common ancestor could not be identified for five generations spanning 17 years (DNA was not available for ancestral cats...
Previous studies have dated the most recent common ancestor (MRCA) between SARS-CoV-2 and its close relatives from bats and pangolins. However, the evolutionary rate thus derived is expected to differ from the rate estimated from sequence divergence of SARS-CoV-2 lineages. Here, I present ...

Wolves, dogs and humans share extremely social and cooperative minds. These similarities are rooted in phylogenetic homology and in the convergence of neuronal and physiological mechanisms, particularly the brain, in the functioning and communication of basic affects and in the mechanisms of stress and...
