Enduring evolutionary embellishment of cloudinids: Lifting the veil of the Cambrian Explosion

Tae-Yoon Park, Jikhan Jung, Mirinae Lee, Sangmin Lee, Yong Yi Zhen, Hong Hua, Lucas V. Warren & Nigel C. Hughes
The Ediacaran–Cambrian transition and the following Cambrian Explosion are among the most fundamental events in the evolutionary history of animals. Understanding these events is enhanced when phylogenetic linkages can be established among animal fossils across this interval and their trait evolution monitored. Doing this is challenging because the fossil record of animal lineages that span this transition is sparse, preserved morphologies generally simple, and lifestyles in the Ediacaran and Cambrian quite different. Here we identify...

Three oaks Microsatellite data

Xiaodan Chen
Knowledge of interspecific divergence and population expansions/contractions of dominant forest trees in response to geological events and climatic oscillations is of major importance to understand their evolution and demography. However, the interspecific patterns of genetic differentiation and spatiotemporal population dynamics of three deciduous Cerris oak species (Q. acutissima, Q. variabilis and Q. chenii) that are widely distributed in China remain poorly understood. In this study, we genotyped 16 nuclear loci in 759 individuals sampled from...

Advanced Cambrian hydroid fossils (Cnidaria: Hydrozoa) extend the medusozoan evolutionary history

Xikun Song, Bernhard Ruthensteiner, Mingxin Lyu, Xi Liu, Jian Wang & Jian Han
Primitive cnidarians are crucial for elucidating the early evolution of metazoan body plans and life histories in the late Neoproterozoic and Palaeozoic. The highest complexity of both evolutionary aspects within cnidarians is found in extant hydrozoans. Many colonial hydrozoans coated with chitinous exoskeletons have the potential to form fossils; however, only a few fossils possibly representing hydroids have been reported, which still require scrutiny. Here, we present an exceptionally well-preserved hydroid found in the Upper...

Data from: Go large or go conical: allometric trajectory of an early Cambrian acrotretide brachiopod

Zhiliang Zhang, Timothy Topper, Yanlong Chen, Luke Stroze, Feiyang Chen, Lars Holmer, Glenn Brock & Zhifei Zhang
Acrotretides are extinct micromorphic brachiopods that exhibited considerable morphological variation during their rapid evolution in the early Palaeozoic. The plano-conical shells of acrotretides are distinct in comparison to other brachiopod groups and despite their diversity and abundance in early Palaeozoic communities, their origins, early evolution, life history and phylogeny are poorly understood. Here, we employ advanced geometric morphometrics to quantitatively investigate ontogenetic variation and allometry in the ventral valve of the oldest known acrotretide species...

Fossil evidence unveils an early Cambrian origin for Bryozoa

Zhiliang Zhang, Zhifei Zhang, Junye Ma, Paul Taylor, Luke Strotz, Sarah Jacquet, Christian Skovsted, Feiyang Chen, Jian Han & Glenn Brock
Bryozoans (ectoprocts or moss animals) are aquatic, dominantly sessile, filter-feeding lophophorates that construct an organic or calcareous modular colonial (clonal) exoskeleton. The presence of six major orders of bryozoans with advanced polymorphisms in lower Ordovician rocks strongly suggests a Cambrian origin for the largest and most diverse lophophorate phylum. However, a lack of convincing bryozoan fossils from the Cambrian has hampered resolution of the true origins and character assembly of earliest members of the group....

Data from: Potential geographic distributions of endangered Opisthopappus Shih in response to environmental changes

Hao Zhang, Hang Ye, En Zang, Qiyang Qie, Shan He, Weili Hao, Yafei Lan, Zhixia Liu, Genlou Sun & Yiling Wang
Environmental changes could dramatically influence the distribution area and niche of organisms. Taihang Mountains contain numerous endemic species, regarded as a center of distribution and diversity for many plant genera. It is necessary that having more comprehensive studies of test climate effects on species in this area. Opisthopappus (containing two species Opisthopappus taihangensis and Opisthopappus longilobus) is an endangered and endemic genus in the Taihang Mountains. Predicting the suitable potential distribution, exploring the niche difference...

A ten-faced hexangulaconulariid from Cambrian Stage 2 of South China

Junfeng Guo, Jian Han, Heyo Van Iten, Zuchen Song, Yaqin Qiang, Wenzhe Wang, Zhifei Zhang & Guoxiang Li
Hexangulaconulariids (Cambrian stages 1‒2) are an extinct group of medusozoan polyps having a biradially symmetrical, fan-shaped periderm that is distinct from those of medusozoan polyps showing three-, four-, five-, or six-fold radial symmetry. Hexangulaconulariids exhibit substantial variation in gross morphology, including variation in the number of faces on each of the two major sides of the periderm. An intermediate taxon of hexangulaconulariids with ten faces (five on each major side) was expected. Here we describe...

Virtual screening for functional foods against the main protease of 2019 novel coronavirus

Binglin Li, Jiao Wang, Xiaoli Zhang & Alejandra B. Omarini
Design and development of an effective method or technologyto combat the 2019 novel coronavirus remains a challenge. In this work, the special attention was paid on the interaction between functional foods and the main protease of 2019-nCoV. Here, 10870 ligands were employed and screened by the molecular docking, which involved 12 kinds of functional foods (carbohydrates, fat acids, phospholipids, vitamin, β-sitosterol, flavonoids, nordihydroguaiaretic acid, curcumin, nookatone, β-pinene, tincturoid, and their isomers/analogs/derivatives). Then, 60 ligands were...
