地球生命の進化を描いた科学インフォグラフィック

4:3 horizontal science infographic poster, theme *The Evolution of Life on Earth: From Primordial Oceans to Human Civilization*, style blends vintage natural history museum illustration plates, academic exhibition placard aesthetics and modern data visualization. Background features immersive cosmic gradient of deep black, ink navy and dark violet, subtly textured with embedded rock grain, faint fossil silhouettes, ocean particle details and sparse glowing stardust for a grand, professional, knowledge-packed visual texture. Top center displays large main headline "The Evolution of Life on Earth" with smaller subhead "From Primordial Oceans to Human Civilization". The whole scene unfolds chronologically from left to right: 1. Far left: Scorching primordial Earth, active volcanoes, lava flows, lightning and first ancient ocean, labeled "~4.6 billion years ago, Earth forms" 2. Adjacent left section: Primordial organic molecules, single-celled organisms, cyanobacteria and rising atmospheric oxygen markers 3. Middle-left: Cambrian Explosion scene full of trilobites, anomalocaris, sponges and early fish, dark red directional arrows show the evolutionary lineage: jawless fish → jawed fish → lobe-finned fish → early tetrapods 4. Central visual focal point: Large semi-realistic theropod dinosaur, accompanied by triceratops, stegosaurus, brachiosaurus, pterosaurs, dinosaur eggs, footprints and fossil specimens, with section header "Mesozoic: The Age of Reptiles", nearby asteroid impact scene clearly marked "~66 million years ago, mass extinction event" 5. Middle-right: Cenozoic mammal scene including mammoths, saber-toothed cats, early horses, whale ancestors and primates, with sequential outline visuals showing the full evolutionary transition of whales from land-dwelling to fully marine species 6. Far right: Hominin evolution sequence of *Australopithecus*, *Homo erectus*, Neanderthal and modern human, section header "Hominin Evolution and Rise of Civilization", paired with the displayed progression of stone tools, fire use, spears and early cultural artifacts A full-width geologic time timeline runs across the entire bottom edge, clearly labels all key geologic periods: Hadean, Archean, Proterozoic, Cambrian, Devonian, Triassic, Jurassic, Cretaceous, Cenozoic, Quaternary, with corresponding time markers at 4.6bya, 3.8bya, 540mya, 252mya, 66mya and present day, 5 small bright red nodes mark all major mass extinction events. Top right dedicated info box carries text "Evolution Does Not Follow A Straight Line" paired with a simplified abstract phylogenetic tree, explicitly notes that humans are only one small branch on the full tree of life. All art uses a semi-realistic, scientifically accurate illustration style, thin white leader lines for annotations, warm yellow strokes for key information highlights, dark red arrows for evolutionary direction cues, clear visual hierarchy of different subject sizes, dense but perfectly legible academic label layout, no Chinese text at all.
