The Phoenix, Fernanda Perez-Alvarez Apr 2021

The Phoenix, Fernanda Perez-Alvarez

Montserrat Annual Writing Prize

This article uses a mythical creature, the phoenix, to examine and illustrate the biological principles for generation of an adult body plan from a single cell. Using the study of developmental biology, it explores the cellular and molecular biology that underpins the massive complexity of creating an adult body plan. It also explores the similarities and differences between different embryos, and how nature and evolution have shaped the biology of those embryos to create different body plans.


Evolutionary Bioethics Advanced By Ernest Everett Just: Implications For Biology, Ethics, And Theology, Theodore Walker Apr 2020

Evolutionary Bioethics Advanced By Ernest Everett Just: Implications For Biology, Ethics, And Theology, Theodore Walker

Perkins Faculty Research and Special Events

Ernest Everett Just (1883-1941) is an acknowledged “pioneer” in biology, being honored with a Black Heritage postage stamp in 1996. Here we discover that Just also made pioneering contributions to general evolutionary bioethics (distinct from special medical bioethics) by advancing a cell-biology-rooted theory of the origin and continuing evolution of ethical behavior influenced by the “law of environmental dependence.”

See especially “The Origin of Man’s Ethical Behavior (1941, unpublished book manuscript) by Ernest Everett Just and Hedwig Schnetzler Just, discovered in 2018 among the collected papers of E.E. Just at the Moorland-Spingarn Research Center at Howard University.

Accordingly, evolution is …


Analysis Of Spheno-Occipital Synchondrosis (Sos) Fusion In A Contemporary Southern Nevada Subadult Hispanic Population Using Archival Cone-Beam Computerized Tomography (Cbct) Images, Megan Baker May 2019

Analysis Of Spheno-Occipital Synchondrosis (Sos) Fusion In A Contemporary Southern Nevada Subadult Hispanic Population Using Archival Cone-Beam Computerized Tomography (Cbct) Images, Megan Baker

UNLV Theses, Dissertations, Professional Papers, and Capstones

This study employs the three-dimensional visualization capability of cone-beam computed tomography (CBCT) to investigate the relationship between chronological age and timing of fusion of the spheno-occipital synchondrosis in a male/female subadult Hispanic population of Southern Nevada. The sample includes cross-sectional data of 374 orthodontic patients (166 males and 208 females) aged 8-20 years. The SOS is scored by a four-stage scoring system as completely open (stage 0), less than half fused (stage 1), more than half fused (stage 2), or completely fused (stage 3) as visualized in the midsagittal plane in the CBCT image. The relationship between SOS fusion stage …


Growing Up In Tell El-Amarna: An Examination Of Growth And Non-Specific Stress Indicators In New Kingdom Children., Ashley Elizabeth Shidner Aug 2018

Growing Up In Tell El-Amarna: An Examination Of Growth And Non-Specific Stress Indicators In New Kingdom Children., Ashley Elizabeth Shidner

Graduate Theses and Dissertations

The health status of the subadult skeletal remains from the South Tombs Cemetery at Tell el-Amarna were assessed by examining fluctuations in childhood growth and rates of skeletal indicators of physiological stress within a biocultural framework. The long bone standardization method outlined by Goode et al. (1993) was used to compare the South Tombs cemetery’s cross-sectional growth data to subadult samples from other cemeteries during which major social, political, and economic changes were taking place. The comparative subadult samples included the HK43 cemetery from Hierakonpolis (Egypt), the African American Cemetery from Cedar Grove (Arkansas), and the St. Martin’s Churchyard from …
