We are all guided by thousands of norms, but how did our capacity for normative cognition evolve? I propose there is a deep but neglected link between normative cognition and practical skill. In modern humans, complex motor skills and craft skills, such as toolmaking, are guided by internally represented norms of correct performance. Moreover, it i...

The ‘Major Transitions in Evolution’ (MTE) framework has emerged as the dominant paradigm for understanding the origins of life's hierarchical organization, but it has been criticized on the grounds that it lacks theoretical unity, that is, that the events included in the framework do not constitute a coherent category. I agree with this criticism,...

BackgroundThe process of calcium carbonate biomineralization has arisen multiple times during metazoan evolution. In the phylum Cnidaria, biomineralization has mostly been studied in the subclass Hexacorallia (i.e. stony corals) in comparison to the subclass Octocorallia (i.e. red corals); the two diverged approximately 600 million years ago. The p...

Globuligerina glinskikhae nov. sp. Gradstein & Waskowska and Globuligerina waskowskae nov. sp. Gradstein are new species of Jurassic planktonic foraminifera from the Middle Jurassic of Dagestan and Poland. G. glinskikhae nov. sp. with its remarkable ‘protoglobigerine’ test may be an early evolutionary offshoot of Globuligerina oxfordiana (Grigelis)...

The analysis of simple sequence repeats (SSRs) in 98 genomes across four genera of the family Polyomaviridae was performed. The genome size ranged from 3962 (BM87) to 7369 bp (BM85) but maximum genomes were in the range of 5–5.5 kb. The GC% had an average of 42% and ranged between 34.69 (BM95) and 52.35 (BM81). A total of 3036 SSRs and 223 cSSRs we...

BackgroundDinoflagellates are aquatic protists particularly widespread in the oceans worldwide. Some are responsible for toxic blooms while others live in symbiotic relationships, either as mutualistic symbionts in corals or as parasites infecting other protists and animals. Dinoflagellates harbor atypically large genomes (~ 3 to 250 Gb), with gene...

This paper presents the concepts and observations in the author’s keynote address at the May 2019 “Opportunity versus Challenge: Exploring Usage of Log-File and Process Data in International Large-Scale Assessments” conference in Dublin, Ireland. This paper recaps briefly some key points that emerged at the December 2018 ETS symposium on process da...

Stress and reproduction are both essential functions for vertebrate survival, ensuring on one side adaptative responses to environmental changes and potential life threats, and on the other side production of progeny. With more than 25,000 species, teleosts constitute the largest group of extant vertebrates, and exhibit a large diversity of life cy...

1. Despite their low contribution to forest carbon stocks, lianas (woody vines) play an important role in the carbon dynamics of tropical forests. As structural parasites, they hinder tree survival, growth and fecundity; hence, they negatively impact net ecosystem productivity and long-term carbon sequestration. 2. Competition (for water and light)...

Sex hormone-binding globulin (Shbg) is an important vertebrate blood carrier protein synthetized in the liver and involved in the transport and local regulation of sex steroids in target tissues. A novel shbg gene (shbgb) with a predominant ovarian expression was recently characterized. Being initially found only in salmonids, this shbgb was origin...
