Human creativity, cultural evolution, and niche construction
Behavioral and Brain Sciences (Impact Factor: 20.77). 02/2000; 23(1):159-160. DOI: 10.1017/S0140525X00382413
Cultural evolution may be even more prolific in the generation of new forms than is biological evolution – especially when it takes the form of creative genius. Yet evolutionary theories have tended to overlook the factors that might select for outstanding individual creativity. A recent dual-inheritance theory is outlined and then integrated with the niche-construction theory of Laland et al.

ABSTRACT: This paper presents a new silica-based coating procedure for the protection of electrogalvanized steel against corrosion. Besides corrosion resistance properties, one of the main objectives of the study was to evaluate the viability of a simple and industrially easy-to-implement substitute to the widely employed chromate coatings that must be abandoned in the next years in the European Union. The silica-based layer was prepared from simple immersion of electrogalvanized sheets in a deposition bath composed of a nanometric silica particles/sodium metasilicate mixture at room temperature. After optimization of several parameters as deposition bath composition, immersion time, drying temperature and so on, the corrosion resistance was evaluated mainly by means of salt spray tests (SST) but also by electrochemical impedance spectroscopy (EIS) measurements. Results have shown to be very promising since the silica-based protective layer behaved almost as well as chromate coatings.Surface and Coatings Technology 05/2005; 194(2-3-194):363-371.

ABSTRACT: This review begins with a definition of biological evolution and a description of its general principles. This is followed by a presentation of the biological basis of culture, specifically the concept of social selection. Further, conditions for cultural evolution are proposed, including a suggestion for language being the cultural replicator corresponding to the concept of the gene in biological evolution. Principles of cultural evolution are put forward and compared to the principles of biological evolution. Special emphasis is laid on the principle of selection in cultural evolution, including presentation of the concept of cultural fitness. The importance of language as a necessary condition for cultural evolution is stressed. Subsequently, prime differences between biological and cultural evolution are presented, followed by a discussion on interaction of our genome and our culture. The review aims at contributing to the present discussion concerning the modern development of the general theory of evolution, for example by giving a tentative formulation of the necessary and sufficient conditions for cultural evolution, and proposing that human creativity and mind reading or theory of mind are motors specific for it. The paper ends with the notion of the still ongoing coevolution of genes and culture.Journal of Genetics 03/2015; 94(1):155-68. DOI:10.1007/s12041-015-0482-4 · 1.09 Impact Factor
