Homo habili

Homo habilis, known as ‘handy man’ is a species of the genus Homo homo habili lived from approximately 2. 4 million years ago, during the Gelasian Pleistocene period.

The discovery and description of this species is credited to both Mary and Louis Leakey, who discovered the fossils in Tanzania between 1962 and 1964. In its appearance and morphology, Homo habilis is the least similar to modern humans of all species in the genus. Homo habilis was short and had disproportionately long arms compared with modern humans, but with a less protruding face than the australopithecines from which it is thought to have descended. Its cranial capacity was less than half of the size of modern humans. Homo habilis a direct human ancestor? Some argue Homo habilis was made up of fossil specimens of Australopithecus and Homo. Homo habilis, although a scavenger rather than a master hunter, is thought to have mastered the Lower Paleolithic Olduwan tool set which utilized stone flakes.

These stone flakes were more advanced than any tools previously used, and gave Homo habilis the edge it needed to prosper in hostile environments previously too formidable for primates. Homo habilis co-existed with other Homo-like bipedal primates, such as Paranthropus boisei, some of which prospered for many millennia. However, Homo habilis, possibly because of its early tool innovation and a less specialized diet, became the precursor of an entire line of new species, whereas Paranthropus boisei disappeared from the fossil record.

Legibus universalibus tenentur ubique terrarum omnes pro quibus latae sunt. A legibus autem universalibus, quae in certo territorio non vigent, eximuntur omnes qui in eo territorio actu versantur. Legibus conditis pro peculiari territorio ii subiciuntur proquibus latae sunt, quique ibidem domicilium vel quasi-domicilium habent et simul actu commorantur, firmo praescripto can. Leges particulares non praesumuntur personales, sed territoriales nisi aliud constet. Vagi obligantur legibus tam universalibus quam particularibus quae vigent in loco in quo versantur. Ordinarii ab eis dispensare possunt, dummodo, si agatur de dispensatione reservata, concedi soleat ab auctoritate cui reservatur. Ignorantia vel error circa leges irritantes vel inhabilitantes earundem effectum non impediunt, nisi aliud expresse statuatur.

Leges authentice interpretatur legislator et is cui potestas authentice interpretandi fuerit ab eodem commissa. Interpretatio autem per modum sententiae iudicialis aut actus administrativi in re peculiari, vim legis non habet et ligat tantum personas atque afficit res pro quibus data est. 18 — Leges quae poenam statuunt aut liberum iurium exercitum coarctant aut exceptionem a lege continent, strictae subsunt interpretationi.
