Book excerpt: A Research Strategy to Examine the Taxonomy of the Red Wolf provides independent guidance about taxonomic research on the red wolf, Canis rufus. Building from the 2019 report Evaluating the Taxonomic Status of the Mexican Gray Wolf and the Red Wolf, this report reviews and ranks research applications to determine the taxonomy of wild canid populations in southern Louisiana and other relevant locations. The report then develops a research strategy to examine the evolutionary relationships between ancient red wolves, the extant managed red wolf populations, and the unidentified canid populations.

But taxonomy, the scientific study of biological classification and evolution, is often highly debated. Members of a species, the fundamental unit of taxonomy and evolution, share a common evolutionary history and a common evolutionary path to the future. Yet, it can be difficult to determine whether the evolutionary history or future of a population is sufficiently distinct to designate it as a unique species. A species is not a fixed entity â€" the relationship among the members of the same species is only a snapshot of a moment in time. Different populations of the same species can be in different stages in the process of species formation or dissolution. In some cases hybridization and introgression can create enormous challenges in interpreting data on genetic distinctions between groups. Hybridization is far more common in the evolutionary history of many species than previously recognized. As a result, the precise taxonomic status of an organism may be highly debated. This is the current case with the Mexican gray wolf (Canis lupus baileyi) and the red wolf (Canis rufus), and this report assesses the taxonomic status for each.

Available in PDF, EPUB and Kindle. Book excerpt: Comparison of 213 skulls of Canis rufus with 214 C. lupus and 335 C. latrans indicate that the red wolf is a distinct species. Before human disruption of the environment, rufus, lups, and latrans maintained their distinct status, and available specimens show no evidence that the red wolf intergraded with either coyote or gray wolf. A series of 71 skulls shows a complete variation from typical rufus to typical latrans. Apparently modification and decline of the red wolf population led to the breakdown of isolation and the formation of a hybrid swarm that suggests possible interbreeding with the coyote. Specimens indicate that as red wolves were extirpated in eastern Texas and elsewhere, a hybrid swarm moved eastward to occupy the niche that was created. By 1969, the swarm spread throughout most of eastern Texas and moved into Louisiana. Pure red wolves continued to survive only in a limited area along the Gulf Coast from Brazoria Counties, Texas, and in Cameron Parish.

Book excerpt: This paper discusses the red wolf's (Canis rufus) status, distribution and ecology; and describes and differentiates the red wolf from the closely related canids. Difficulties in distinguishing red wolves from coyotes (Canis latrans) and red wolf-coyote hybrids have resulted in much confusion over the range and status of the red wolf.

This book was released on 2011 with total page 326 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hybridization poses the greatest threat to the recovery of the critically endangered red wolf (Canis rufus ) in eastern North Carolina. Mitigating the impacts of hybridization requires understanding the scale at which this process occurs across the landscape. Such descriptions of hybridization also require an evaluation of the methods used to assess hybridization and mechanisms regulating this process. The goal of this dissertation was to discern landscape-level patterns of hybridization between red wolves and coyotes ( C. latrans ) and elucidate mechanisms governing interbreeding between these species. To describe the patterns of hybridization between these species, we used non-invasive genetic sampling to characterize the genetic profile of canids across the landscape. In 2008, we collected scat across a 22 000 km 2 region surrounding the Red Wolf Experimental Population Area (RWEPA) and used mitochondrial and nuclear microsatellite DNA data to identify individual canids and determine their ancestry (Chapter 1). From this survey we identified no pure red wolves and found little evidence of red wolf introgression into the coyote population. A similar follow-up survey conducted in 2010 confirmed that red wolves were restricted the RWEPA (Chapter 2). Coyotes were found to be widely distributed across the entire landscape; hybrids, however, were rare compared to the abundance of the parental species. For both surveys we utilized Bayesian clustering methods to estimate genetic ancestry for individuals identified through molecular genotyping. We tested the ability of these methods to detect genetic introgression under different scenarios using data from the red wolf pedigree (Chapter 3). We also examined characteristics of red wolves involved in known hybridization events within the RWEPA to illuminate potential mechanisms governing this process. Our review found that most of the red wolves that hybridized with coyotes did so following the disruption of a stable breeding pair of red wolves, often due to human-caused mortality (Chapter 4). Most hybrid litters occurred in the furthest west portion of the RWEPA and were produced by young, first-time breeding red wolves with mixed ancestry. Our findings provide valuable information regarding the patterns, process and detection of hybridization that can guide future management of this system.

Available in PDF, EPUB and Kindle. Book excerpt: If Darwin were to examine the evidence today using modern science, would his conclusions be the same? Charles Darwin’s On the Origin of Species, published over 150 years ago, is considered one of history’s most influential books and continues to serve as the foundation of thought for evolutionary biology. Since Darwin’s time, however, new fields of science have immerged that simply give us better answers to the question of origins. With a Ph.D. in cell and developmental biology from Harvard University, Dr. Nathaniel Jeanson is uniquely qualified to investigate what genetics reveal about origins. The Origins Puzzle Comes Together If the science surrounding origins were a puzzle, Darwin would have had fewer than 15% of the pieces to work with when he developed his theory of evolution. We now have a much greater percentage of the pieces because of modern scientific research. As Dr. Jeanson puts the new pieces together, a whole new picture emerges, giving us a testable, predictive model to explain the origin of species. A New Scientific Revolution Begins Darwin’s theory of evolution may be one of science’s “sacred cows,” but genetics research is proving it wrong. Changing an entrenched narrative, even if it’s wrong, is no easy task. Replacing Darwin asks you to consider the possibility that, based on genetics research, our origins are more easily understood in the context of . . . In the beginning . . . God, with the timeline found in the biblical narrative of Genesis. There is a better answer to the origins debate than what we have been led to believe. Let the revolution begin! About the Author Dr. Nathaniel Jeanson is a scientist and a scholar, trained in one of the most prestigious universities in the world. He earned his B.S. in Molecular Biology and Bioinformatics from the University of Wisconsin-Parkside and his PhD in Cell and Developmental Biology from Harvard University. As an undergraduate, he researched the molecular control of photosynthesis, and his graduate work involved investigating the molecular and physiological control of adult blood stem cells. His findings have been presented at regional and national conferences and have been published in peer-reviewed journals, such as Blood, Nature, and Cell. Since 2009, he has been actively researching the origin of species, both at the Institute for Creation Research and at Answers in Genesis.
