Natural Selection as a Population-Level Causal Process [PDF]

, 2006
Recent discussions in the philosophy of biology have brought into question some fundamental assumptions regarding evolutionary processes, natural selection in particular.

Environmental coupling of selection and heritability limits evolution [PDF]

, 2006
There has recently been great interest in applying theoretical quantitative genetic models to empirical studies of evolution in wild populations. However, while classical models assume environmental constancy, most natural populations exist in variable ...

The human gut microbiome across the life course

FEBS Letters, EarlyView.
Despite significant individual variation and continuous change throughout life, the human gut microbiome follows some life stage‐specific trends. This article provides a brief overview of how gut microbiome composition shifts across different phases of life. Created in BioRender. Özkurt, E. (2026) https://BioRender.com/8q4nrnc.

Natural Selection and Morality [PDF]

Ideas y Valores, 2006
Resumen:En este ensayo abordo los intentos, relativamente recientes, de dar una explicación de la moralidad como adaptación por selección natural. Mi exposición tiene una introducción y cuatro partes: en la primera explico en qué consiste la paradoja del

Genomic Legacies of Ancient Adaptation Illuminate GC-Content Evolution in Bacteria

Microbiology Spectrum, 2023
Bacterial evolution is characterized by strong purifying selection as well as rapid adaptive evolution in changing environments. In this context, the genomic GC content (genomic GC) varies greatly but presents some level of phylogenetic stability, making

Natural selection and the predictability of evolution in Timema stick insects

Science, 2018
Estimating the predictability of evolution Evolution results from expected effects, such as selection driving alleles toward fixation, and stochastic effects, such as unusual environmental variation and genetic drift.

Are Random Drift and Natural Selection Conceptually Distinct? [PDF]

, 2001
The latter half of the twentieth century has been marked by debates in evolutionary biology over the relative significance of natural selection and random drift: the so-called neutralist/selectionist debates.

Phosphoinositides and inositol phosphates as molecular glues

FEBS Letters, EarlyView.
Inositol phosphates (IPs) and phosphoinositides (PIPs) regulate diverse eukaryotic processes. Beyond recruiting signaling proteins or acting as structural cofactors, recent studies suggest they mediate protein–protein interactions as natural molecular glues.

Teoria social e biologia: perspectivas e problemas da introdução do conceito de história nas ciências biológicas Social Theories and Biology: perspectives and problems of the introduction of the historical concept into biological sciences

História, Ciências, Saúde: Manguinhos, 2001
A teoria da evolução por seleção natural de Charles Darwin, ao relacionar os seres vivos genealogicamente, interpreta as espécies e sua fantástica diversidade como uma história de transformações lentas e graduais.

Structure and evolution of the squamate major histocompatibility complex as revealed by two Anolis lizard genomes

Frontiers in Genetics, 2022
The major histocompatibility complex (MHC) is an important genomic region for adaptive immunity and has long been studied in ecological and evolutionary contexts, such as disease resistance and mate and kin selection.
