Face of a southern yellowjacket (Vespula squamosa)Yellowjackets may be confused with other wasps, such as hornets and paper wasps such as Polistes dominula.A typical yellowjacket worker is about 12 mm (0.47 in) long, with alternating bands on the abdomen; the queen is larger, about 19 mm (0.75 in) long (the different patterns on their abdomens help separate various species).
While most species of this genus inhabit North America, four Vespula species inhabit Europe, namely V. austriaca, V. germanica, V. rufa, and V. vulgaris.; Two common European species, the German wasp (V. germanica) and the common wasp (V. vulgaris), have established in other countries; both species are now found in New Zealand, Australia, and South America, while the former has also been ...
Multiregional evolution holds that the human species first arose around two million years ago and subsequent human evolution has been within a single, continuous human species. This species encompasses all archaic human forms such as Homo erectus , Denisovans , and Neanderthals as well as modern forms, and evolved worldwide to the diverse ...
Human evolution (origins of society and culture) – Transition of human species to anthropologically modern behavior; Inversion (evolutionary biology) – Hypothesis in developmental biology; Mosaic evolution – Evolution of characters at various rates both within and between species
Human DNA recovered from remains found in Europe is revealing our species’ shared history with Neanderthals. The trove is the oldest Homo sapiens DNA ever documented, scientists say.
Paravespula is a small subgenus of yellowjacket wasps, including some of the best-known wasp species in the world: the German wasp, Vespula germanica; the eastern yellowjacket Vespula maculifrons; the western yellowjacket Vespula pensylvanica; and the common wasp, Vespula vulgaris.
Bone fragments unearthed in a cave in central Germany show that our species ventured into Europe's cold higher latitudes more than 45,000 years ago - much earlier than previously known - in a ...
