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.

Overwintering in Tegu Lizards
Overwintering in Tegu Lizards DENIS V. ANDRADE,1 COLIN SANDERS,1, 2 WILLIAM K. MILSOM,2 AND AUGUSTO S. ABE1 1 Departamento de Zoologia, Universidade Estadual Paulista, Rio Claro, SP, Brasil 2 Department of Zoology, University of British Columbia, Vancouver, BC, Canada Abstract. The tegu, Tupinambis merianae, is a large South American teiid lizard, which is active only during part of the year (hot summer months), spending the cold winter months sheltered in burrows in the ground. This pattern of activity is accompanied by seasonal changes in preferred body temperature, metabolism, and cardiorespiratory function. In the summer months these changes are quite large, but during dormancy, the circadian changes in body temperature observed during the active season are abandoned and the tegus stay in the burrow and al- low body temperature to conform to the ambient thermal profile of the shelter. Metabolism is significantly depressed during dormancy and relatively insensitive to alterations in body temperature. As metabolism is lowered, ventilation, gas exchange, and heart rate are adjusted to match the level of metabolic demand, with concomitant changes in blood gases, blood oxygen transport capacity, and acid-base equilibrium. Seasonality and the Tegu Life Cycle As with any other ectothermic organism, the tegu lizard, Tupinambis merianae, depends on external heat sources to regulate body temperature. Although this type of thermoregulatory strategy conserves energy by avoiding the use of me- tabolism for heat production (Pough, 1983), it requires that the animal inhabit a suitable thermal environment to sustain activity. When the environment does not provide the range of temperatures that enables the animal to be active year round, many species of ectothermic vertebrates become seasonally inactive (Gregory, 1982). -

Skeletal Variation in Extant Species Enables Systematic Identification of New Zealand's Large, Subfossil Diplodactylids
Scarsbrook et al. BMC Ecol Evo (2021) 21:67 BMC Ecology and Evolution https://doi.org/10.1186/s12862-021-01808-7 RESEARCH Open Access Skeletal variation in extant species enables systematic identifcation of New Zealand’s large, subfossil diplodactylids Lachie Scarsbrook1*, Emma Sherratt2, Rodney A. Hitchmough3 and Nicolas J. Rawlence1 Abstract New Zealand’s diplodactylid geckos exhibit high species-level diversity, largely independent of discernible osteologi- cal changes. Consequently, systematic afnities of isolated skeletal elements (fossils) are primarily determined by comparisons of size, particularly in the identifcation of Hoplodactylus duvaucelii, New Zealand’s largest extant gecko species. Here, three-dimensional geometric morphometrics of maxillae (a common fossilized element) was used to determine whether consistent shape and size diferences exist between genera, and if cryptic extinctions have occurred in subfossil ‘Hoplodactylus cf. duvaucelii’. Sampling included 13 diplodactylid species from fve genera, and 11 Holocene subfossil ‘H. cf. duvaucelii’ individuals. We found phylogenetic history was the most important predictor of maxilla morphology among extant diplodactylid genera. Size comparisons could only diferentiate Hoplodactylus from other genera, with the remaining genera exhibiting variable degrees of overlap. Six subfossils were positively identifed as H. duvaucelii, confrming their proposed Holocene distribution throughout New Zealand. Conversely, fve subfossils showed no clear afnities with any modern diplodactylid genera, implying either increased morphological diversity in mainland ‘H. cf. duvaucelii’ or the presence of at least one extinct, large, broad-toed diplodactylid species. Keywords: Diplodactylidae, Ecomorphology, Geometric morphometrics, Hoplodactylus duvaucelii, Taxonomy Background (e.g. coloration and scalation), with interspecifc skeletal New Zealand’s lizard fauna is characteristic of isolated variation rarely analysed. -
The Genetic Factors of Bilaterian Evolution Peter Heger1*, Wen Zheng1†, Anna Rottmann1, Kristen a Panfilio2,3, Thomas Wiehe1
RESEARCH ARTICLE The genetic factors of bilaterian evolution Peter Heger1*, Wen Zheng1†, Anna Rottmann1, Kristen A Panfilio2,3, Thomas Wiehe1 1Institute for Genetics, Cologne Biocenter, University of Cologne, Cologne, Germany; 2Institute for Zoology: Developmental Biology, Cologne Biocenter, University of Cologne, Cologne, Germany; 3School of Life Sciences, University of Warwick, Gibbet Hill Campus, Coventry, United Kingdom Abstract The Cambrian explosion was a unique animal radiation ~540 million years ago that produced the full range of body plans across bilaterians. The genetic mechanisms underlying these events are unknown, leaving a fundamental question in evolutionary biology unanswered. Using large-scale comparative genomics and advanced orthology evaluation techniques, we identified 157 bilaterian-specific genes. They include the entire Nodal pathway, a key regulator of mesoderm development and left-right axis specification; components for nervous system development, including a suite of G-protein-coupled receptors that control physiology and behaviour, the Robo- Slit midline repulsion system, and the neurotrophin signalling system; a high number of zinc finger transcription factors; and novel factors that previously escaped attention. Contradicting the current view, our study reveals that genes with bilaterian origin are robustly associated with key features in extant bilaterians, suggesting a causal relationship. *For correspondence: [email protected] Introduction The taxon Bilateria consists of multicellular animals -

FITZGERALD, Jos~ MARIA CHANI, AND OSCAR E. DONADio 1\vo speciesof tegu lizards of the generaTupinambis, 1: teguixin, and 1: rufes- cens (fig. 21.1), are heavily exploited for their skins in Argentina. Each year, more than 1,250,000 skins are exportedfrom Argentina to the United States, Canada,Mexico, Hong Kong, Japan, and severalEuropean countries. Some skins are reexportedor madeinto exotic leatheraccessories, but the majority of the tegus are destinedto becomecowboy boots in Texas(Hemley 1984a).Sur- prisingly, the trade has continued at this level for at least 10 years (Hemley 1984a:Norman 1987). An internal Argentine market also exists foltegu skins, but it hasnot beenquantified. The large trade in Tupinambishas causedconcern among some government and nongovernmentorganizations because the biology of the lizards is essen- tially undescribed,and the effectson the tegu populationsand associatedbiotic communitiesof removing more than one million individuals annually are un- known. Although population declineshave not beendocumented, it seemspru- dent to study Tupinambisbiology and formulate long-term managementand conservationplans if the ecological, economic, and cultural valuesof the re- sourceare to be guaranteed. The Tupinambistrade is important to the Argentine economy.The export valueof the resourceis worth millions of dollars annually,and for rural peoples in northern Argentina with low wagesor intermittent employment,tegu hunt- ing is a significant sourceof income. -

JEWELL1 & RICHARD A. B. LESCHEN2* 1 216 Ripponvale Road, R.D., Cromwell, New Zealand 2 New Zealand Arthropod Collection, Private Bag 92170, Auckland, New Zealand, [email protected] * Address correspondence to R. Leschen Abstract A gecko from alpine scree in the Takitimu Mountains, South Island, New Zealand, is described as Hoplodactylus cryptozoicus n. sp. Hoplodactylus cryptozoicus is characterized by an orange mouth lining, a short tail, minute body scales, and a distinctive colour pattern which includes bright orange patches. It may be closely related to H. nebulosus (McCann) based on the sharing of grey pigment on the tongue. Hoplodactylus cryptozoicus is known from only a single locality and is one of the few species of Hoplodactylus in New Zealand that inhabits rocks in the alpine zone. Key words: Reptilia; taxonomy; endemism; conservation Introduction The New Zealand gecko fauna presently comprises 18 validly named species placed into two endemic genera of the Diplodactylinae, Hoplodactylus Fitzinger 1843 and Naultinus Gray 1842. Both genera occur throughout the country and remain poorly studied with sev- eral species needing to be described. Most species, in fact, are threatened and/or of con- servation importance (Hitchmough 2002). Even though there are only a handful of species, taxonomic revisions are lacking with the last monograph that of McCann (1955). Since that time five species were described in the 1980’s (Robb 1980; Thomas 1981; Whi- taker 1985), including the mysterious Hoplodactylus delcourti Bauer and Russell, the larg- est species of gecko in the world and known from a single specimen (Bauer and Russell 1986, 1987; Russell and Bauer 1986). -
A Phylogenomic Perspective on the Radiation of Ray-Finned Fishes Based Upon Targeted Sequencing of Ultraconserved Elements
1 A phylogenomic perspective on the radiation of 2 ray-finned fishes based upon targeted sequencing of 3 ultraconserved elements 1;2;∗ 1;2 1 1 4 Michael E. Alfaro , Brant C. Faircloth , Laurie Sorenson , Francesco Santini 1 5 Department of Ecology and Evolutionary Biology, University of California, Los Angeles, CA, USA 2 6 These authors contributed equally to this work 7 ∗ E-mail: [email protected] arXiv:1210.0120v1 [q-bio.PE] 29 Sep 2012 1 8 Summary 9 Ray-finned fishes constitute the dominant radiation of vertebrates with over 30,000 species. 10 Although molecular phylogenetics has begun to disentangle major evolutionary relationships 11 within this vast section of the Tree of Life, there is no widely available approach for effi- 12 ciently collecting phylogenomic data within fishes, leaving much of the enormous potential 13 of massively parallel sequencing technologies for resolving major radiations in ray-finned 14 fishes unrealized. Here, we provide a genomic perspective on longstanding questions regard- 15 ing the diversification of major groups of ray-finned fishes through targeted enrichment of 16 ultraconserved nuclear DNA elements (UCEs) and their flanking sequence. Our workflow 17 efficiently and economically generates data sets that are orders of magnitude larger than 18 those produced by traditional approaches and is well-suited to working with museum speci- 19 mens. Analysis of the UCE data set recovers a well-supported phylogeny at both shallow and 20 deep time-scales that supports a monophyletic relationship between Amia and Lepisosteus 21 (Holostei) and reveals elopomorphs and then osteoglossomorphs to be the earliest diverging 22 teleost lineages.
