Early projectiles

Microscopic and morphometric analysis of Uluzzian backed lunates from Grotta del Cavallo, southern Italy, dated between ~45,000 and ~40,000 years ago, indicates that modern humans used these small lithics as hunting armatures and delivered them mechanically using a bow or a spearthrower.

    A full picture of biodiversity across space and time requires macro- and microevolutionary approaches.

Comment & Opinion

  • Comment |

    The past half century has seen a move from a multiregionalist view of human origins to widespread acceptance that modern humans emerged in Africa. Here the authors argue that a simple out-of-Africa model is also outdated, and that the current state of the evidence favours a structured African metapopulation model of human origins.

    Currently honeybees are the sole model insect pollinator for regulatory pesticide risk assessments globally. Here we question whether this surrogacy approach provides adequate protection against potential non-target impacts of pesticide exposure for the wide diversity of insect pollinators on which agricultural production and wild plant ecosystems depend.

    A simulation of expansion, fragmentation and extirpation of species ranges over multiple glacial–interglacial cycles matches empirical biodiversity gradients and shows that high levels of biodiversity in the tropics can emerge from temporally variable but spatially patchy precipitation regimes, driven by allopatric speciation.

    Measurement comparisons of ancient and modern carp push back the initial stages of aquaculture to 6000 bc, raising the possibility that rice paddy and fish co-culture systems are much older than previously thought. This research suggests carp were later independently domesticated twice, once in Europe and once in Asia.

    A Free Ocean Carbon Enrichment experiment that manipulates seawater pH on a coral reef flat shows that the level of ocean acidification at which net dissolution of corals occurs may arrive much sooner than expected.

Reviews

    Transnational corporations control large proportions of the industries and commodities that directly and indirectly impact the environment. Here, the authors discuss the problems, but also potential benefits, of such consolidation for sustainability.
