A supervolcano is a volcano capable of producing a volcanic eruption with an ejecta mass greater than 1015 kg (1012 t). Supervolcanoes occur when magma in the mantle rises into the crust but is unable to break through it and pressure builds in a large and growing magma pool until the crust is unable to contain the pressure. This can occur at hotspots (for example, Yellowstone Caldera) or at subduction zones (for example, Toba).
Homo habilis. An extinct hominid of the genus Homo that lived between 2.3 and 1.4 million years ago in Africa in the early Pleistocene period. H habilis was short, but had a less protruding face and a higher, rounder and larger brain cavity (Â±650 cc) than Australopithecus (Â±450 cc).
Habilis and H. erectus. Homo habilis. This is an interesting and important hominid species, which is believed to have formed the bridge between erectus and Australopithecines. However, they also lived with both these species together in different times.It has been a common agreement that these hominids were the first to evolve of the Genus: Homo.omo erectus. Homo erectus was one of the hominid species, which is now extinct from the world. They were the first to stand in a standard upright posture out of all the hominids, and that has given their species name erectus.
