The Emergence of Tense in Early Bantu
Examination of a set of non-Bantu Niger-Congo languages shows that most are aspect-prominent languages, that is, they either do not encode tense —the majority case— or, as the quotation indicates, there is reason to think that some have added tense to an original aspectual base. Comparative consideration of tense-aspect categories and morphology suggests that early and Proto-Niger-Congo were as...
متن کاملInfluence of salicylic acid pre-treatment on emergence and early seedling growth of cucumber (Cucumis sativus)under salt stress
Salicylic acid (SA) is a common, plant-produced signal molecule that is responsible for inducing tolerance to a number of biotic and abiotic stresses. An experiment was therefore conducted to test whether the application of SA at various concentrations (0, 0.25, 0.50 or 1.0 mM) through a seed-soaking method would protect cucumber (Cucumis sativus L.) seedlings subjected to salt stress. Aft...
متن کاملEarly imitation and the emergence of a sense of agency
In this paper, I would like to emphasize the developmental role of imitation as a foundation for the emergence of a sense of agency (i.e. a sense of being the owner of one’s own action). There is a large body of psychological and neuroimaging experiments that have demonstrated that perception of action share some common neural and cognitive mechanisms with action generation, action simulation, ...
متن کاملEarly emergence of Yersinia pestis as a severe respiratory pathogen
Yersinia pestis causes the fatal respiratory disease pneumonic plague. Y. pestis recently evolved from the gastrointestinal pathogen Y. pseudotuberculosis; however, it is not known at what point Y. pestis gained the ability to induce a fulminant pneumonia. Here we show that the acquisition of a single gene encoding the protease Pla was sufficient for the most ancestral, deeply rooted strains of...
متن کاملEarly hominin diversity and the emergence of the genus Homo.
Bipedalism is a defining trait of hominins, as all members of the clade are argued to possess at least some characters indicative of this unusual form of locomotion. Traditionally the evolution of bipedalism has been treated in a somewhat linear way. This has been challenged in the last decade or so, and in this paper I consider this view in light of the considerable new fossil hominin discover...
