Abstract The well‐known debate on the nature and origin of intracellular inclusions ( ICI s) in silicified microfossils from early N eoproterozoic B itter S prings F ormation has recently been revived by reports possible fossilized nuclei phosphatized animal embryo‐like fossils E diacaran D oushantuo outh C hina. revisitation this discussion prompted a critical comprehensive investigation s some oldest indisputable eukaryote microfossils—the ornamented acritarchs ictyosphaera delicata...
Abstract The imbalance between human activities and Earth's natural surface adversely affects the sustainability of Earth system. From an understanding suitability functions potential ramifications policy decisions, this study proposes a sustainable geographical pattern. It introduces national‐to‐provincial downscaling approach to optimizing national‐scale zoning scheme that covers 60%–80% land development protection in China creating major function model. Taking as case area, following...
Abstract Multicellularity arose multiple times in the evolutionary history of eukaryotes, and simple multicellularity may have a deep tracing back to Paleoproterozoic. However, complex multicellular organisms with cellular tissue differentiation did not appear fossil record until Mesoproterozoic, it is Ediacaran Period (635–541 Ma) when diverse assemblages eukaryotes evolved. In intervening Tonian (ca. 1000–720 Ma), poorly documented. To address this knowledge gap, we investigated Chuaria...
The Tonian Period (ca. 1000–720 Ma) follows the ‘boring billion' in Mesoproterozoic Era and precedes ‘snowball Earth' glaciations Cryogenian Period. It represents a critical transition Earth history. Geochemical data indicate that may have witnessed significant increase atmospheric pO2 levels major from predominantly sulfidic to ferruginous mid-depth seawaters. Molecular clock estimates suggest early animals diverged Period, raising intriguing possibility of coupled environmental changes...
Abstract The early E diacaran L antian F ormation in S outh C hina contains some of the oldest known representatives morphologically complex macroorganisms, including various macroalgae and putative animals. macroalgal fossils have been described previously several publications, but no taxonomic treatment has published for animal fossils. This hampers our ability to fully evaluate communicate significance these potentially important macrofossils. To address this deficiency, here we provide a...
Most sponges have biomineralized spicules. Molecular clocks indicate sponge classes diverged in the Cryogenian, but oldest spicules are Cambrian age. Therefore, either evolved spiculogenesis long after their divergences or Precambrian were not amenable to fossilization. The former hypothesis predicts independent origins of among and presence transitional forms with weakly spicules, this prediction has been tested using paleontological data. Here, we report an early that, like several other...
The global diversity of Proterozoic eukaryote fossils is poorly quantified despite its fundamental importance to the understanding macroevolutionary patterns and dynamics on early Earth. Here we report a new construction fossil from Paleoproterozoic Cambrian based comprehensive data compilation quantitative analyses. resulting taxonomic richness curve verifies Cryogenian glaciations as major divide that separates “Boring Billion” Ediacaran periods, with former characterized by prolonged...
As one of the core working parts a combine harvester, cleaning device directly affects operation performance whole machine. This is especially case on hilly and gently sloping terrain, which, due to uneven ground, causes harvester body incline material accumulates side, resulting in high loss rate. To solve this problem, self-leveling screen control system based fuzzy PID algorithm are developed for caterpillar enabling it operate gentle slopes 10°. verify applied system, simulation tests,...
Abstract Macrofossils with unambiguous biogenic origin and predating the one-billion-year-old multicellular fossils Bangiomorpha Proterocladus interpreted as crown-group eukaryotes are quite rare. Horodyskia is one of these few macrofossils, it extends from early Mesoproterozoic Era to terminal Ediacaran Period. The biological interpretation this enigmatic fossil, however, has been a matter controversy since its discovery in 1982, largely because there was no evidence for preservation...
