The cultural evolution of cultural evolution [PDF]

Philosophical Transactions of the Royal Society B: Biological Sciences, 2020
What makes fast, cumulative cultural evolution work? Where did it come from? Why is it the sole preserve of humans? We set out a self-assembly hypothesis: cultural evolution evolved culturally. We present an evolutionary account that shows this hypothesis to be coherent, plausible, and worthy of further investigation. It has the following steps: (0) in

The evolution of deception [PDF]

Royal Society Open Science, 2021
Deception plays a critical role in the dissemination of information, and has important consequences on the functioning of cultural, market-based and democratic institutions. Deception has been widely studied within the fields of philosophy, psychology, economics and political science.

The fruticose genera in the Ramalinaceae (Ascomycota, Lecanoromycetes): their diversity and evolutionary history [PDF]

MycoKeys, 2020
We present phylogenetic analyses of the fruticose Ramalinaceae based on extensive collections from many parts of the world, with a special focus on the Vizcaíno deserts in north-western Mexico and the coastal desert in Namibia.

Evolution in pecunia [PDF]

Proceedings of the National Academy of Sciences, 2021
Significance We use an analogy between financial trading strategies and biological species and characterize an evolutionary stable strategy in an ecology with fix-mix strategies. The basis of our paper is that dividends are not exogenous but increase with the wealth invested in an asset, as is the case in a production economy.

Mutually stabilizing interactions between proto-peptides and RNA

Nature Communications, 2020
Cooperative relationships are widespread among different classes of biopolymers and are predicted to have existed during emergence of life. This study shows that proto-peptides engage in mutually stabilizing interactions with RNA, providing support for ...

Natural variation in the maternal and zygotic mRNA complements of the early embryo in Drosophila melanogaster

BMC Genomics, 2022
Background Maternal gene products supplied to the egg during oogenesis drive the earliest events of development in all metazoans. After the initial stages of embryogenesis, maternal transcripts are degraded as zygotic transcription is activated; this is ...

Evolution of the nucleus [PDF]

Current Opinion in Cell Biology, 2014
The nucleus represents a major evolutionary transition. As a consequence of separating translation from transcription many new functions arose, which likely contributed to the remarkable success of eukaryotic cells. Here we will consider what has recently emerged on the evolutionary histories of several key aspects of nuclear biology; the nuclear pore ...

The metabolic network of the last bacterial common ancestor

Communications Biology, 2021
Joana C. Xavier, Rebecca E. Gerhards and colleagues reconstruct the habitat and lifestyle of the last bacterial common ancestor (LBCA) through the construction of the metabolic network and gene tree analysis of 146 LCBA protein families.

Quantum speed of evolution of neutral mesons [PDF]

Eur. Phys. J. Plus 138, 597 (2023), 2022
We investigate the quantum-mechanical time-evolution speed limit for neutral $K$ and $B$ mesons, both single as well as correlated, within the framework of open quantum systems. The role of coherence--mixing, a crucial feature of the open system evolution of the underlying quantum systems (here, the mesons), on the quantum-mechanical time-evolution ...
