Introspection dynamics: a simple model of counterfactual learning in asymmetric games

New Journal of Physics, 2022
Social behavior in human and animal populations can be studied as an evolutionary process. Individuals often make decisions between different strategies, and those strategies that yield a fitness advantage tend to spread.

Collective narratives catalyse cooperation

Humanities & Social Sciences Communications, 2022
Humans invest in fantastic stories—mythologies. Recent evolutionary theories suggest that cultural selection may favour moralising stories that motivate prosocial behaviours.

Heterogeneous individual motility biases group composition in a model of aggregating cells

Frontiers in Ecology and Evolution, 2022
Aggregative life cycles are characterized by alternating phases of unicellular growth and multicellular development. Their multiple, independent evolutionary emergence suggests that they may have coopted pervasive properties of single-celled ancestors ...

Immediate action is the best strategy when facing uncertain climate change

Nature Communications, 2018
Reducing the adverse effects of climate change triggered by human activity requires cooperation on a global scale. Modelling this challenge as an evolutionary game shows that the emerging contributions of selfish players depend strongly on the risk ...

Single-cell phenotypic plasticity modulates social behavior in Dictyostelium discoideum

iScience, 2023
Summary: In Dictyostelium chimeras, “cheaters” are strains that positively bias their contribution to the pool of spores, i.e., the reproductive cells resulting from development.

Hierarchy Theory of Evolution and the Extended Evolutionary Synthesis: Some Epistemic Bridges, Some Conceptual Rifts [PDF]

, 2018
Contemporary evolutionary biology comprises a plural landscape of multiple co-existent conceptual frameworks and strenuous voices that disagree on the nature and scope of evolutionary theory.

How many samples are needed to infer truly clonal mutations from heterogenous tumours?

BMC Cancer, 2019
Background Modern cancer treatment strategies aim to target tumour specific genetic (or epigenetic) alterations. Treatment response improves if these alterations are clonal, i.e. present in all cancer cells within tumours.

The Antimicrobial Resistance Crisis: An Inadvertent, Unfortunate but Nevertheless Informative Experiment in Evolutionary Biology

Frontiers in Ecology and Evolution, 2021
The global rise of antimicrobial resistance (AMR) phenotypes is an exemplar for rapid evolutionary response. Resistance arises as a consequence of humanity’s widespread and largely indiscriminate use of antimicrobial compounds.

PALEONTOLOGY AND EVOLUTIONARY THEORY [PDF]

Evolution, 1974
In the introduction to the recently published collection Models in Paleobiology, Schopf (1972, p. 4) says, "We look with awe at the results which have followed the application of fundamental chemistry in a geochemical context, and the use of cartesian methodology in molecular biology.

The impact of information about tobacco-related reproductive vs. general health risks on South Indian women's tobacco use decisions

Evolutionary Human Sciences, 2021
Smokeless tobacco use among Indian women is increasing despite prevention efforts. Evolutionary theories suggest that reproductive-aged women should be more concerned about immediate threats to reproduction than threats to survival occurring late in life.
