A descriptive qualitative approach is employed using literature analysis and the interpretation of Landsat satellite imagery from 2011 and 2022. The findings show …

Indirect Genetic Effects Among Neighbors Promote Cooperation And Accelerate Adaptation In A Small-Scale Human Society, Jordan S. Martin, Bret Beheim, Michael Gurven, Hillard Kaplan, Jonathan Stieglitz, Benjamin C. Trumble, Paul Hooper, Daniel K. Cummings, Daniel Eid Rodriguez, Adrian V. Jaeggi

ESI Publications

Explaining the rapid evolution of human cooperation and its role in our species’ biodemographic success remains a major evolutionary puzzle. To address this challenge, we tested a social drive hypothesis, which predicts that social plasticity and social selection in human groups cause indirect genetic effects that accelerate the adaptation of fitness, promoting population growth via feedback between the environmental causes and evolutionary consequences of cooperation. Using Bayesian multilevel models to analyze fertility data from a small-scale society, we demonstrate that density- and frequency-dependent indirect genetic effects on fitness promote the evolution of cooperation among neighboring women, increasing the rate of …

Humans Rule? Implications Of Religious Undergraduates’ Changing Environmental Perceptions, J. Robert Nielson

Undergraduate Honors Theses

Addressing climate change requires correctly appraising one’s ethic toward the Earth. Historically, people have navigated their relationship to the natural world via environmental ethics of both religious and secular origin. Aldo Leopold described developing this relationship via the land ethic, a culturally informed process, as “an evolutionary possibility and an ecological necessity.” A land ethic provides a reference point from which individuals and societies make decisions about the Earth and its resources. This thesis considers the evolving land ethic of a young population of conservative Christian students at Brigham Young University with two separate cohorts of non-biology major undergraduates enrolled …

Open Field Two-Texture Preference Testing Is Not Associated With The Neuropathic Pain-Like Phenotype That Occurs Following Mouse Cervical Contusion Spinal Cord Injury, David A. Jaffe, Megan A. Lyttle, Angelo C. Lepore

Farber Institute for Neuroscience Faculty Papers

Development of neuropathic pain (NP) is one of the major complications associated with spinal cord injury (SCI). While well-established methods such as von Frey mechanical and facial grimace testing are often used to assess SCI-induced NP-like behaviors in animal models, these assays have significant limitations, including experimenter bias and long periods of active testing and analysis.
