Evolution In The Information Age: Rediscovering The Nature Of The Organism, Daniel R. Brooks
Evolution In The Information Age: Rediscovering The Nature Of The Organism, Daniel R. Brooks
Harold W. Manter Laboratory of Parasitology: Faculty and Staff Publications
The newest synthesis of evolutionary thought is emerging, and promises to return evolutionary biology to Darwin’s panoramic view of life. The key element is a long-standing dualism in evolutionary theory. This dualism has a long history within evolutionary biology, being manifested under guises such as: (1) the nature of the organism and the nature of the conditions, (2) internal and external, or intrinsic and extrinsic, factors, (3) production and exchanges, (4) boundary and initial conditions, (5) metabolism and replication, (6) energy and information, and (7) costs and benefits, and conflict and resolution. A partially retrospective review suggests that there is …

Phylogenetic and divergence date analyses indicate that the occurrence of Taenia tapeworms in humans pre-dates the development of agriculture, animal husbandry and domestication of cattle (Bos spp.) or swine (Sus scrofa) Taeniid tapeworms in Africa twice independently colonized hominids and the genus Homo prior to the origin of modern humans. Dietary and behavioural shifts, from herbivory to scavenging and carnivory, as early Homo entered the carnivore guild in the Pliocene/Pleistocene, were drivers for host switching by tapeworms to hominids from carnivores including hyaenids and felids. Parasitological data provide a unique means of elucidating the historical ecology, foraging behavior …
