Artificial Life, 2007 The evolution of complexity has been a central theme for Biology [2] and Artificial Life research [1]. It is generally agreed that complexity has increased in our universe, giving way to life, multi-cellularity, societies, and systems of higher ...

Few remarks on evolution algebras [PDF]
arXiv, 2013 In the present paper we study some algebraic properties of evolution algebras. Moreover, we reduce the study of evolution algebras of permutations to two special types of evolution algebras, idempotents and absolute nilpotent elements of the algebra. We study three-dimensional evolution algebras whose each element of evolution basis has infinite period.

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.

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 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.

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 ...

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.

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 ...

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 ...
