Xenosaurus Tzacualtipantecus. the Zacualtipán Knob-Scaled Lizard Is Endemic to the Sierra Madre Oriental of Eastern Mexico
Xenosaurus tzacualtipantecus. The Zacualtipán knob-scaled lizard is endemic to the Sierra Madre Oriental of eastern Mexico. This medium-large lizard (female holotype measures 188 mm in total length) is known only from the vicinity of the type locality in eastern Hidalgo, at an elevation of 1,900 m in pine-oak forest, and a nearby locality at 2,000 m in northern Veracruz (Woolrich- Piña and Smith 2012). Xenosaurus tzacualtipantecus is thought to belong to the northern clade of the genus, which also contains X. newmanorum and X. platyceps (Bhullar 2011). As with its congeners, X. tzacualtipantecus is an inhabitant of crevices in limestone rocks. This species consumes beetles and lepidopteran larvae and gives birth to living young. The habitat of this lizard in the vicinity of the type locality is being deforested, and people in nearby towns have created an open garbage dump in this area. We determined its EVS as 17, in the middle of the high vulnerability category (see text for explanation), and its status by the IUCN and SEMAR- NAT presently are undetermined. This newly described endemic species is one of nine known species in the monogeneric family Xenosauridae, which is endemic to northern Mesoamerica (Mexico from Tamaulipas to Chiapas and into the montane portions of Alta Verapaz, Guatemala). All but one of these nine species is endemic to Mexico.

This new species, Lepidophyma cuicateca sp. nov., is known from two areas in the Cuicatlan Valley. Lepidophyma cuicateca sp. nov. is a member of the Lepidophyma gaigeae species Group and is characterized by its small body size, small size of tubercular body scales, poorly differentiated caudal whorls and interwhorls, and relatively large dorsal, ven- tral and gular scales. It lives in shady places, below rocks along the Apoala River, and is commonly found in plantain, sapodilla, cherimoya, mango and coffee plantations, as well as tropical deciduous forest. The description of L. cuicateca sp. nov. increases the number of species in the L. gaigeae Group to five. Key words: Squamata, Lepidophyma gaigeae Group, Lepidophyma cuicateca sp. nov., new species, Xantusiidae, Mex- ico, Oaxaca Resumen Se describe una nueva especie de Lepidophyma para la parte oaxaqueña de la reserva de la biosfera de Tehuacán- Cuicatlán.

HISTORY and ANALYSIS of the CREATION RESEARCH SOCIETY by William E
AN ABSTRACT OF THE THESIS OF William E. Elliott for the degree ofMaster of Science in General Science presented on March 1, 1990. Title: History and Analysis of theCreation ltee Society Redacted for Privacy Abstractapproved: The resurgence of creationismthe past few years has been led by advocates of recent-creationism. These individuals, a minority among creationists in general, argue that the entire universe was created approximately 10,000 years ago in one six- day period of time.Recent-creationists support their position by appealing to the Genesis account of creation and scientific data. Their interpretation of Genesis is based on the doctrines of conservative, evangelical Christianity. Their interpretation of scientific data is informed by their theological presuppositions. The scientific side of recent-creationism is supported by several organizations, most of which had their origin in one group, the Creation Research Society. The CRS is a major factor in the rise of the modern creationist movement. Founded in 1963, this small (c. 2000 mem- bers) group claims to be a bona-fide scientific society engaged in valid scientific re- search conducted from a recent-creationist perspective. These claims are analyzed and evaluated. The Society's history is discussed, including antecedent creationist groups. Most of the group's founders were members of the American Scientific Affiliation, and their rejection of changes within the ASA was a significant motivating factor in founding the CRS. The organization, functioning, and finances of the Society are de- tailed with special emphasis on the group's struggles for independence and credibility. founding the CRS.

Origin and Significance of Lovén's Law in Echinoderms

C. Paul1 and Frederick H. C. Hotchkiss2 1School of Earth Sciences, University of Bristol, Bristol, UK <[email protected]> 2Marine and Paleobiological Research Institute, P.O. Box 1016, Vineyard Haven, Massachusetts, USA 02568 <hotchkiss@MPRInstitute. org> Abstract.—Lovén’s Law described the position of larger basicoronal ambulacral plates in echinoids. The smaller basi- coronal plates form first in ontogeny. We restate Lovén’s Law to describe the position of first ambulacral plates using Carpenter’s ambulacra and left (L) or right (R) as: AR, BL, CR, DL, ER, with EA the pair of ambulacra both identical and adjacent. First ambulacral plates of the Cambrian edrioasteroid, Walcottidiscus, code identically. The transition from a tri-radiate 1-1-1 pattern to the 2-1-2 ambulacral pattern of Walcottidiscus and other pentaradiate Paleozoic echinoderms results in Lovén’s Law. This provides an hypothesis for the origin of Lovén’s Law and predicts its widespread occurrence among echinoderm classes. The ‘BD different’ pattern of primary brachioles in pentaradiate glyptocystitoid Rhombifera results from subterminal branching of the ambulacra. The ontogenetic sequence was triradiate, then lateral ambulacra bifurcated, and finally second brachioles developed. -
Louis Pasteur's Views on Creation, Evolution, and the Genesis Of
Answers Research Journal 1 (2008): 43–52. www.answersingenesis.org/contents/379/Louis-Pasteur.pdf Louis Pasteur’s Views on Creation, Evolution, and the Genesis of Germs Alan L. Gillen, Professor of Biology, Department of Biology and Chemistry, Liberty University, 1971 University Boulevard, Lynchburg, VA 24502 Frank J. Sherwin III, Science Editor, Institute for Creation Research, 1806 Royal Lane, Dallas, TX 75229 “There is no remembrance of men of old, and even those who are yet to come will not be remembered by those who follow.” Ecclesiastes 1:11 (NIV) Abstract In past years revisionist historians have been rewriting the worldview of Christians who have made some of the major discoveries in biology and medicine. It appears that postmodern revisionists are rewriting history to support their agenda of a more “secular” explanation to science. The Judeo- Christian worldview is not politically correct in most universities. This is true in regard to past scientists such as Louis Pasteur who believed in creation. According to reliable, primary sources such as René Vallery-Radot, Pasteur’s son-in-law, Pasteur’s unique view and application of operational science gave him a significant advantage, benefiting mankind in a number of critical areas. Shortly after Darwin published On the Origin of Species in 1859, Pasteur began to challenge the idea of spontaneous generation—the foundation of the evolutionary view on the origin of life. Pasteur’s simple, but elegant swan-necked flask experiments not only put to rest the organic life-from-non- life idea, but also set the foundation for the law of biogenesis: life only comes from life.
