Thinking About Evolutionary Mechanisms: Natural Selection [PDF]
, 2004 This paper explores whether natural selection, a putative evolutionary mechanism, and a main one at that, can be characterized on either of the two dominant conceptions of mechanism, due to Glennan and the team of Machamer, Darden, and Craver, that ...

Evolutionary ecology of hares (Lepus spp.) from northwest Africa: the existence of cryptic species and description of a new species (Lepus saharae sp. nov.) [PDF]
, 2019 Objective: We examine the different pressures that lead to the occurrence of new species and thus to their phylogenies. From an evolutionary ecology perspective, we examine the phylogenetic relationships of different lineages, as well as the evolutionary

Investigating sex differences in developmental origins of adolescent depression
Frontiers in Child and Adolescent PsychiatryIntroductionEvolutionary hypotheses propose that fetuses show “predictive adaptive” responses to the prenatal environment based on likely continuity with the postnatal environment, and males and females have different adaptive priorities.

Diversity and complexity in neural organoids
FEBS Letters, EarlyView.Neural organoid research aims to expand genetic diversity on one side and increase tissue complexity on the other. Chimeroids integrate multiple donor genomes within single organoids. Self‐organising multi‐identity organoids, exogenous cell seeding, or enforced assembly of region‐specific organoids contribute to tissue complexity.

Evolutionary synthesis of kinematic mechanisms [PDF]
Artificial Intelligence for Engineering Design, Analysis and Manufacturing, 2008 AbstractThis paper discusses the application of genetic programming to the synthesis of compound two-dimensional kinematic mechanisms, and benchmarks the results against one of the classical kinematic challenges of 19th century mechanical design. Considerations for selecting a representation for mechanism design are presented, and a number of human ...

Biophysical approaches for studying viral entry
FEBS Letters, EarlyView.Viruses infect all living organisms and have been responsible for major epidemics and pandemics. Their ongoing evolutionary battle with host defenses creates a constant need for improved tools to study viral behavior. Advancing methods to probe viral attachment, fusion, and genome release deepen our understanding of how infections begin and support the

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.
