    PASSAGE 10
    One area of paleoanthropological study involves the eating and dietary habits of hominids, erect bipedal primates — including early humans. It is clear that at some stage of history, humans began to carry their food to central places, called home bas, where it was shared and consumed with the young and other adults. The u of home bas is a fundamental component of human social behavior; the common meal rved at a common hearth is a powerful symbol, a mark of social unity. Home ba behavior does not occur among nonhuman primates and is rare among mammals. It is unclear when humans began to u home bas, what kind of communications and social relations were involved, and w
hat the ecological and food-choice contexts of the shift were. Work on early tools, surveys of paleoanthropological sites, development and testing of broad ecological theories, and advances in comparative primatology are contributing to knowledge about this central chapter in human prehistory.
    One innovative approach to the issues involves studying damage and wear on stone tools. Rearchers make tools that replicate excavated specimens as cloly as possible and then try to u them as the originals might have been ud, in woodcutting, hunting, or cultivation. Depending on how the tool is ud, characteristic chippage patterns and microscopically distinguishable polishes develop near the edges. The first application of this method of analysis to stone tools that are 1.5 million to 2 million years old indicates that, from the start, an important function of early stone tools was to extract highly nutritious food — meat and marrow — from large animal carcass. Fossil bones with cut marks caud by stone tools have been discovered lying in the same 2-million-year-old layers that yielded the oldest such tools and the oldest hominid specimens (including humans) with larger than ape-sized brains. This discovery increas scientists certainty a
bout when human ancestors began to eat more meat than prent-day nonhuman primates. But veral questions remain unanswered: how frequently meat eating occurred; what the social implications of meat eating were; and whether the incread u of meat coincides with the beginnings of the u of home bas.

    PASSAGE 11
    Plants are subject to attack and infection by a remarkable variety of symbiotic species and have evolved a diver array of mechanisms designed to frustrate the potential colonists. The can be divided into preformed or passive defen mechanisms and inducible or active systems. Passive plant defen compris physical and chemical barriers that prevent entry of pathogens, such as bacteria, or render tissues unpalatable or toxic to the invader. The external surfaces of plants, in addition to being covered by an epidermis and a waxy cuticle, often carry spiky hairs known as trichomes, which either prevent feeding by incts or may even puncture and kill inct larvae. Other trichomes are sticky and glandular and effectively trap and immobilize incts.
