Living in a dangerous climate : climate change and human evolution
\"Living in a Dangerous Climate provides a journey through human and Earth history, showing how a changing climate has affected human evolution and society. Is it possible for humanity to evolve quickly, or is slow, gradual, genetic evolution the only way we change? Why did all other Homo species go extinct while Homo sapiens became dominant? How did agriculture, domestication, and the use of fossil fuels affect humanity's growing dominance? Do today's dominant societies - devoted as they are to Darwinism and \"survival of the fittest\" - contribute to our current failure to meet the hazards of a dangerous climate? Unique and thought provoking, the book links scientific knowledge and perspectives of evolution, climate change, and economics in a way that is accessible and exciting for the general reader. The book is also valuable for courses on climate change, human evolution, and environmental science\"-- Provided by publisher.

Malacological insights into the marine ecology and changing climate of the late Pleistocene early Holocene Queen Charlotte Islands archipelago, western Canada, and implications for early peoples
The first intertidal species to colonize the Queen Charlotte Islands archipelago along the northeastern Pacific margin of Canada after the last glacial maximum (LGM) was Macoma nasuta at 13 210 ± 80
14
C years BP. Prior to this time, molluscs were likely excluded where grounded ice extended from the 2 km thick Cordilleran ice sheet on mainland British Columbia. Low water temperatures, high sedimentation rates, high turbidity, dilution, and low primary productivity limited invertebrate colonization subsequent to the LGM, a period of rapid sea-level and climate change. As an adult, M. nasuta is a facultative deposit-suspension feeder that tolerates high turbidity and lowered salinity, and its pediveligers and early juveniles must also have been able to survive these conditions. Subsequently, in addition to M. nasuta, Macoma irus (inquinata), Saxidomus giganteus, Protothaca staminea, Protothaca tenerrima, Hiatella pholadis, Clinocardium nuttallii, and Mytilus trossulus constituted a typical intertidal bivalve assemblage. These findings are explained in terms of the physiology, feeding mechanisms, development, and sediment preferences of living molluscs. The disappearance of most bivalve species between ~11 000 and 10 000
14
C years BP indicates the onset of a short interval of low sea-surface temperatures coincident with the Younger Dryas cooling event. Some cold-hardy species persisted, including Clinocardium californiense, Mya truncata, and Serripes groenlandicus. Bivalve species not previously reported as Pleistocene fossils were collected in sediments dating older than 10 000
14
C years BP. They include Macoma incongrua, Musculus taylori, Mytilimeria nuttallii, and Tellina nuculoides. Fossil assemblages of intertidal molluscs are used to map ancient shorelines and indicate which species were available as a subsistence resource for early peoples from at least 13 210 ± 80
14
C years BP. Intertidal food biomass densities may have reached present commercially harvested levels on southern Moresby Island by 8800 ± 70
14
C years BP and on northern Graham Island by 8990 ± 50
14
C years BP. When early peoples might have been migrating along the littoral zone, the molluscan productivity of the outer coast was much higher than it is at present.

Parasites, Paleoclimate, and the Peopling of the Americas
Paleoparasitological findings and paleoclimate modelling simulations indicate that early peoples migrating via the Clovis first route across Beringia into North America could not have traversed the required distance in time to provide a reasonable explanation for the presence of the hookworm in the preColumbian Americas. The introduction of the hookworm into the Americas by a land migration at around 13,000 years BP could have happened only under extraordinary circumstances and even then would have required displacement rates that appear to have no parallel in the archaeology of the continent. This implies that while the Clovis people may have been the first migrants to the Americas, they were almost certainly not the only such migrants.

Late Pleistocene coastal paleogeography of the Queen Charlotte Islands, British Columbia, Canada, and its implications for terrestrial biogeography and early postglacial human occupation
Molluscs, sediment lithology, and published sub-bottom profiles are used to deduce sea levels, outline the influence of glacially induced crustal displacement, and reconstruct the paleoenvironment of the northeast Pacific late Quaternary coastline. Geo-spatial modelling shows subaerially exposed land that could have been inhabited by plants and animals, and also coastally migrating early North American peoples. Ice-free terrain, present by at least 13 790±150 14C years BP, a land bridge, and edible molluscs are identified. Queen Charlotte Islands (QCI) late Pleistocene coastal paleogeography may assist in explaining the biogeography of many terrestrial plant and animal species along the broader northeastern Pacific margin and provide evidence for researchers seeking late Pleistocene-early Holocene glacial refugia. Late Pleistocene-early Holocene coastlines that are not drowned and that may harbour early archaeological sites are identified along the western QCI, where migrants probably first travelled and the westernmost British Columbia mainland, where the effects of glacial ice were reduced.

Hunting Down Woody
The DNA keys of the genetic keyboard are necessary if the music is to be played, but they are neither the player nor the score.Robert G. B. Reid, Biological Emergences: Evolution by Natural Experiment
In my early teenage years, I used to slip down to my older brothers’ room in the basement when they were not home and listen to their record collection, especially the Beatles’ Abbey Road, Janis Joplin’s Pearl, and, at Christmas, a record by Herb Alpert and his Tijuana Brass. I would search through the stack of LPs and belt out Woody Guthrie’s “This Land Is Our Land” and “The Farm-Labor Train,” and his son Arlo’s rendition of Steve Goodman’s “City of New Orleans.”Married three times, Woody Guthrie and his wives had eight children. It was during his third marriage that his increasingly unpredictable behavior was finally diagnosed as Huntington’s disease – the same degenerative disease that had led to his mother’s institutionalization thirty years previously. He died on October 3, 1967.
