Friendship and natural selection [PDF]
Proceedings of the National Academy of Sciences, 2014 More than any other species, humans form social ties to individuals who are neither kin nor mates, and these ties tend to be with similar people. Here, we show that this similarity extends to genotypes. Across the whole genome, friends’ genotypes at the single nucleotide polymorphism level tend to be positively correlated (homophilic).

THE CAUSES OF NATURAL SELECTION [PDF]
Evolution, 1990 We discuss the necessary and sufficient conditions for identifying the cause of natural selection on a phenotypic trait. We reexamine the observational methods recently proposed for measuring selection in natural populations and illustrate why the multivariate analysis of selection is insufficient for identifying the causal agents of selection.

Identification of Follower Status Based on Male Proximity Score in Crested Macaque
Hayati Journal of Biosciences, 2020 Crested macaque live in multimale-multifemale social groups where temporary association (consortship) typically occurs. Current theory and these limited qualitative observations suggest the hypothesis that behavior functions as a means for males to gain ...

Natural Selection and Scale Invariance
Life, 2023 This review points out that three of the essential features of natural selection—competition for a finite resource, variation, and transmission of memory—occur in an extremely simple, thermalized molecular population, one of colliding “billiard balls ...

The natural selection of bad science [PDF]
Royal Society Open Science, 2016 Poor research design and data analysis encourage false-positive findings. Such poor methods persist despite perennial calls for improvement, suggesting that they result from something more than just misunderstanding.

Natural Selection and Causal Productivity [PDF]
, 2013 In the recent philosophical literature, two questions have arisen concerning the status of natural selection: 1) Is it a population-level phenomenon, or is it an organism-level phenomenon?

Natural selection promotes antigenic evolvability. [PDF]
PLoS Pathogens, 2013 The hypothesis that evolvability - the capacity to evolve by natural selection - is itself the object of natural selection is highly intriguing but remains controversial due in large part to a paucity of direct experimental evidence.

COVID-19 pandemic and “survival of the fittest”
Journal of Infection in Developing Countries, 2021 Occurrence and recurrence of COVID-19 cases have been observed globally. The complex relationship of host-pathogen and the environment plays a vital role in understanding the widespread recurrence of the SARS-CoV-2 among humans.

The strength and pattern of natural selection on gene expression in rice
Nature, 2020 Levels of gene expression underpin organismal phenotypes1,2, but the nature of selection that acts on gene expression and its role in adaptive evolution remain unknown1,2.
