Origins of the Classical Gene Concept, 1900–1950: Genetics, Mechanistic, Philosophy, and the Capitalization of Agriculture

In the period of “classical genetics” (roughly 1915–1950), the common view of the gene was mechanistic—that is, genes were seen as individual, atomistic units, as material components of the chromosomes. Although it was recognized early on that genes could interact and influence each other’s expression, they were still regarded as individually functioning units, much like the chemists’ atoms or molecules. Although geneticists in particular knew the story was more complex, the atomistic gene remained the central view for a variety of reasons. It fit the growing philosophy of mechanistic materialism in the life sciences, as biologists tried to make their field more quantitative, rigorous, and predictive, like physics and chemistry. Conceptually and pedagogically, it provided a simple way to depict genes (as beads on a string) that fit with the exciting new work on chromosomal mapping. The atomistic gene also fit well with the increasing drive to move capital into agriculture, both for potential patenting purposes and for ease of experimental manipulation and prediction. It is the latter point that the present essay explores most thoroughly. The rise of agriculture as an industrialized process provided a context and material support that fueled much of the rapid growth of genetics in the first half of the 20th century

“Culling the Herd”: Eugenics and the Conservation Movement in the United States, 1900–1940

While from a late twentieth- and early twenty-first century perspective, the ideologies of eugenics (controlled reproduction to eliminate the genetically unfit and promote the reproduction of the genetically fit) and environmental conservation and preservation, may seem incompatible, they were promoted simultaneously by a number of figures in the progressive era in the decades between 1900 and 1950. Common to the two movements were the desire to preserve the ‘‘best’’ in both the germ plasm of the human population and natural environments (including not only natural resources, but also undisturbed nature preserves such as state and national parks and forests). In both cases advocates sought to use the latest advances in science to bolster and promote their plans, which in good progressive style, involved governmental planning and social control. This article explores the interaction of eugenic and conservationist ideologies in the careers of Sacramento banker and developer Charles M. Goethe and his friend and mentor, wealthy New York lawyer Madison Grant. In particular, the article suggests how metaphors of nature supported active work in both arenas

Mesolithic and late neolithic/Bronze Age activity on the site of the American Express Community Stadium, Falmer, East Sussex

Excavations on the site of the American Express Community Stadium, Falmer, East Sussex have revealed evidence for over 7,000 years of human activity. The earliest occupation was a mesolithic camp, where the production of flint tools (microliths) was carried out, on a scale unprecedented in East Sussex. There was little recognisable human activity in the early and middle neolithic but geoarchaeological investigations have shown that the landscape continued to change, with probable deforestation causing colluvial deposition within the river valley to the west. In the late neolithic/Early Bronze Age, a series of three ring ditches were dug, close to the location of the mesolithic pits. There are a number of possibilities as to what these ring ditches represent, but the most likely explanation is a group of barrows or other type of ceremonial ring ditch. Whatever their function, the structures were re-visited later in prehistory, a testament to the continued topographic importance of the site. Finally the site became the focus of Anglo-Saxon habitation, including a sunken-featured building, perhaps an outlying part of the precursor to Falmer village

Constraints from TcT_c and the isotope effect for MgB2_2

With the constraint that $T_c = 39$ K, as observed for MgB$_2$, we use the Eliashberg equations to compute possible allowed values of the isotope coefficient, $\beta$. We find that while the observed value $\beta= 0.32$ can be obtained in principle, it is difficult to reconcile a recently calculated spectral function with such a low observed value

However, there is a limited understanding of potentially shared or analogous rules across vocal displays in different taxa. Recent work on songbirds has investigated syntax using network-based modelling. This technique quantifies features such as connectivity (adjacent signals in a sequence) and recurring patterns. Here, we apply network-based modelling to the complex, hierarchically structured songs of humpback whales (Megaptera novaeangliae) from east Australia. Given the song's annual evolving pattern and the cultural conformity of males within a population, network modelling captured the patterns of multiple song types over 13 consecutive years. Song arrangements in each year displayed clear ‘small-world’ network structure, characterized by clusters of highly connected sounds. Transitions between these connected sounds further suggested a combination of both structural stability and variability. Small-world network structure within humpback songs may facilitate the characteristic and persistent vocal learning observed. Similar small-world structures and transition patterns are found in several birdsong displays, indicating common syntactic patterns among vocal learning in multiple taxa. Understanding the syntactic rules governing vocal displays in multiple, independently evolving lineages may indicate what rules or structural features are important to the evolution of complex communication, including human language.PostprintPostprintPeer reviewe
