Sperling1 and Richard G. Stockey Department of Geological Sciences, Stanford University, 450 Serra Mall, Building 320, Stanford, CA 94305, USA From the symposium “From Small and Squishy to Big and Armored: Genomic, Ecological and Paleontological Insights into the Early Evolution of Animals” presented at the annual meeting of the Society for Integrative and Comparative Biology, January 3–7, 2018 at San Francisco, California. 1E-mail: [email protected] Synopsis Animals originated and evolved during a unique time in Earth history—the Neoproterozoic Era. This paper aims to discuss (1) when landmark events in early animal evolution occurred, and (2) the environmental context of these evolutionary milestones, and how such factors may have affected ecosystems and body plans. With respect to timing, molecular clock studies—utilizing a diversity of methodologies—agree that animal multicellularity had arisen by 800 million years ago (Ma) (Tonian period), the bilaterian body plan by 650 Ma (Cryogenian), and divergences between sister phyla occurred 560–540 Ma (late Ediacaran). Most purported Tonian and Cryogenian animal body fossils are unlikely to be correctly identified, but independent support for the presence of pre-Ediacaran animals is recorded by organic geochemical biomarkers produced by demosponges. -
Phylogenetic Comparative Methods: a User's Guide for Paleontologists
Phylogenetic Comparative Methods: A User’s Guide for Paleontologists Laura C. Soul - Department of Paleobiology, National Museum of Natural History, Smithsonian Institution, Washington, DC, USA David F. Wright - Division of Paleontology, American Museum of Natural History, Central Park West at 79th Street, New York, New York 10024, USA and Department of Paleobiology, National Museum of Natural History, Smithsonian Institution, Washington, DC, USA Abstract. Recent advances in statistical approaches called Phylogenetic Comparative Methods (PCMs) have provided paleontologists with a powerful set of analytical tools for investigating evolutionary tempo and mode in fossil lineages. However, attempts to integrate PCMs with fossil data often present workers with practical challenges or unfamiliar literature. In this paper, we present guides to the theory behind, and application of, PCMs with fossil taxa. Based on an empirical dataset of Paleozoic crinoids, we present example analyses to illustrate common applications of PCMs to fossil data, including investigating patterns of correlated trait evolution, and macroevolutionary models of morphological change. We emphasize the importance of accounting for sources of uncertainty, and discuss how to evaluate model fit and adequacy. Finally, we discuss several promising methods for modelling heterogenous evolutionary dynamics with fossil phylogenies. Integrating phylogeny-based approaches with the fossil record provides a rigorous, quantitative perspective to understanding key patterns in the history of life. 1. Introduction A fundamental prediction of biological evolution is that a species will most commonly share many characteristics with lineages from which it has recently diverged, and fewer characteristics with lineages from which it diverged further in the past. This principle, which results from descent with modification, is one of the most basic in biology (Darwin 1859). -

Constraints on the Timescale of Animal Evolutionary History
Palaeontologia Electronica palaeo-electronica.org Constraints on the timescale of animal evolutionary history Michael J. Benton, Philip C.J. Donoghue, Robert J. Asher, Matt Friedman, Thomas J. Near, and Jakob Vinther ABSTRACT Dating the tree of life is a core endeavor in evolutionary biology. Rates of evolution are fundamental to nearly every evolutionary model and process. Rates need dates. There is much debate on the most appropriate and reasonable ways in which to date the tree of life, and recent work has highlighted some confusions and complexities that can be avoided. Whether phylogenetic trees are dated after they have been estab- lished, or as part of the process of tree finding, practitioners need to know which cali- brations to use. We emphasize the importance of identifying crown (not stem) fossils, levels of confidence in their attribution to the crown, current chronostratigraphic preci- sion, the primacy of the host geological formation and asymmetric confidence intervals. Here we present calibrations for 88 key nodes across the phylogeny of animals, rang- ing from the root of Metazoa to the last common ancestor of Homo sapiens. Close attention to detail is constantly required: for example, the classic bird-mammal date (base of crown Amniota) has often been given as 310-315 Ma; the 2014 international time scale indicates a minimum age of 318 Ma.

Clearing the Highest Hurdle: Human-Based Case Studies Broaden Students’ Knowledge of Core Evolutionary Concepts
The Journal of Effective Teaching an online journal devoted to teaching excellence Clearing the highest hurdle: Human-based case studies broaden students’ knowledge of core evolutionary concepts Alexander J. Werth1 Hampden-Sydney College, Hampden-Sydney, VA 23943 Abstract An anonymous survey instrument was used for a ten year study to gauge college student attitudes toward evolution. Results indicate that students are most likely to accept evolu- tion as a historical process for change in physical features of non-human organisms. They are less likely to accept evolution as an ongoing process that shapes all traits (including biochemical, physiological, and behavioral) in humans. Students who fail to accept the factual nature of human evolution do not gain an accurate view of evolution, let alone modern biology. Fortunately, because of students’ natural curiosity about their bodies and related topics (e.g., medicine, vestigial features, human prehistory), a pedagogical focus on human evolution provides a fun and effective way to teach core evolutionary concepts, as quantified by the survey. Results of the study are presented along with useful case studies involving human evolution. Keywords: Survey, pedagogy, biology, evolution, Darwin. All science educators face pedagogical difficulties, but when considering the social rami- fications of scientific ideas, few face as great a challenge as biology teachers. Studies consistently show more than half of Americans reject any concept of biological evolution (Harris Poll, 2005, Miller et al., 2006). Students embody just such a cross-section of soci- ety. Much ink has been spilled explaining how best to teach evolution, particularly to unwilling students (Cavallo and McCall, 2008, Nelson, 2008). -
ZOOLOGY Exploring the Biodiversity of Colorado and Theworld
CHAPTER 4 — ZOOLOGY Exploring the Biodiversity of Colorado and the World CHAPTER 4 ZOOLOGY Exploring the Biodiversity of Colorado and the World Jeffrey T. Stephenson, Before the Museum Paula E. Cushing, The first collections of specimens that make up what is now the Denver John R. Demboski, and Museum of Nature & Science were actually established well before the Frank-T. Krell founding of the institution in 1900, the selection of a board of trustees, or the construction of a building to house and exhibit the specimens. Edwin Carter (1830–1900) (Fig. 4.1) collected Colorado birds and mammals from the 1860s through the 1890s. Born in New York in 1830, Carter arrived in Colorado in 1859 hoping to make it rich in the goldfields, but he soon became interested in the region’s natural history. He learned hide tanning and, as his prospects for hitting the mother lode faded, he earned his living selling buckskin clothing that he handcrafted. Carter supplemented these earnings by mar- keting foodstuffs and other provisions to the growing population of successful and (mostly) unsuccessful prospectors flooding the region. His interest in nature turned to concern as he observed dwindling numbers of mammals and birds, owing largely to habitat destruction and overhunting. Period photographs of the area’s mining district show a landscape largely denuded of vegetation. By the 1870s, Carter noted that many animal species were becoming scarce. The state’s forests were being devastated, ranches and farms were replacing open prairie, and some species, including the last native bison in Colorado, were on the verge of extirpation or extinction. -
