On the cover: About 100,000 years ago, Diverse Homo species coexisted with our own species Homo sapiens. The Harbin cranium, or the Dragon Man, is one of the best preserved Middle Pleistocene human fossils. The cranium has a large cranial capacity falling in the range of modern humans, but is combined with a mosaic of primitive and derived characters. Phylogenetic analyses suggest that the diversification of the Homo genus had a much more distant past than previously presumed. The Harbin cranium and some other Middle Pleistocene human fossils from China represent the third human lineage that is the sister group of H. sapiens and has closer relationships with H. sapiens than Neanderthals with H. sapiens. Multiple Homo lineages in Africa, Asia and Europe probably had a strong capability for long-distance dispersal, but remained in relatively small and isolated populations. Diverse palaeoenvironments in Asia may have produced a varied biogeographic sink for human evolution. |

Graphical abstract SARS-CoV-2 has recently been found to have spread from humans to minks and then to have transmitted back to humans. However, it is unknown to what extent the human-to-human transmission caused by the variant has reached. Here, we used publicly available SARS-CoV-2 genomic sequences from both humans and minks collected in Denmark and the Netherlands, and combined phylogenetic analysis with Bayesian inference under an epidemiological model, to trace the possibility of person-to-person transmission.
