Abstract
Climate change -- how do plants cope?
Judy R M Allen
65 - 68
General principles of palaeoclimate studies, with a particular emphasis on palynology, though other methods are also mentioned, such as the use of mass spectrometry to measure the ratio of oxygen isotopes in foraminifera shells. Explains the use of pollen diagrams by reference to an upland site at Laguna de la Roya in Zamora (Spain), and demonstrates how distribution maps can be drawn up of the pollen density of a particular species such as beech to analyse its migration patterns over time. Following a discussion of the types of response that plants make to climatic change, the author concludes with a plea for establishing a conservation strategy to take account of the climatic needs of plants potentially threatened by future global warming.
When, where, and why did humans lose their fur?
Charles B Goodhart
78 - 80
Speculates that modern humans may have lost their fur through sexual selection ie, that males preferred naked to hairy females. Earlier hominids including Homo erectus, archaic Homo sapiens, and Neanderthalers (who lived around the Pleistocene ice cap) would have retained their furry coats, leaving human nakedness to evolve late, perhaps in a small population living at a high latitude in Europe or Asia during the last Interglacial period (c 100,000~BP). This population would have been pale-skinned since no solar protection afforded by pigmentation would have been necessary due to the high latitude, while the need for Vitamin D would have favoured this development. With the advance of the last Ice Age, their descendants may then have moved south where they acquired pigmented skins and reduced beards and head hair. Although populations of still furry archaic H sapiens and even H erectus may have continued to live on for a time in the Tropics (until they became extinct), the naked H sapiens may have been unable to interbreed with them following a period of genetic isolation in the north. Also suggests that the cultural revolution of the later Palaeolithic may have been due, in part, to biological changes in human intelligence.
