Ancient and Current Chaos Theories [PDF]
Interdisciplinary Description of Complex Systems, 2006 Chaos theories developed in the last three decades have made very important contributions to our understanding of dynamical systems and natural phenomena. The meaning of chaos in the current theories and in the past is somewhat different from each other.

Correlates of early reproduction and apparent fitness consequences in male Soay sheep
Ecology and Evolution, 2023 Life history trade‐offs are ubiquitous across species and place constraints on the timing of life history events, including the optimal age at first reproduction.

, 2004 A common method of improving how well understood a theory is, is by comparing it to another theory which has been better developed. Radical interpretation is a theory which attempts to explain how communication has meaning.

Evolutionary interplay between viruses and R‐loops
FEBS Letters, EarlyView.Viruses interact with specialized nucleic acid structures called R‐loops to influence host transcription, epigenetic states, latency, and immune evasion. This Perspective examines the roles of R‐loops in viral replication, integration, and silencing, and how viruses co‐opt or avoid these structures.

Monogamy removes constraints on reproductive tissue investment imposed by intense sexual selection
Scientific ReportsA key factor influencing the reproductive success and fitness of an individual is the allocation of resources to reproductive tissue. Previous research has documented positive influences of sexual selection on the evolution of male traits such as testes ...

Toxins, 2022 Snake venom is an adaptive ecological trait that has evolved primarily as a form of prey subjugation. Thus, the selection pressure for toxin diversification is exerted by the prey’s physiological targets, with this pressure being particularly acute for ...

Circulating histones as clinical biomarkers in critically ill conditions
FEBS Letters, EarlyView.Circulating histones are emerging as promising biomarkers in critical illness due to their diagnostic, prognostic, and therapeutic potential. Detection methods such as ELISA and mass spectrometry provide reliable approaches for quantifying histone levels in plasma samples.

Sole-Manrubia model of biological evolution: some new insights
, 2002 The Sole-Manrubia model of ``macro''-evolution describes the origination, evolution and extinction of species on geological time scales. We report some properties of this model which provide deep insight into this simple model which captures several ...
