010 THE FIRST VERTEBRATES 脊椎動物出現

THE FIRST VERTEBRATES ~530 million years Vertebrates are members of the subphylum Vertebrata, chordates with backbones or spinal columns. About 58,000 species of vertebrates have been described. Vertebrata is the largest subphylum of chordates, and contains many familiar groups of large land animals. Vertebrates comprise cyclostomes, bony fish, sharks and rays, amphibians, reptiles, mammals, and birds. Extant vertebrates range in size from the carp species Paedocypris, at as little as 7.9 mm (0.3 inch), to the Blue Whale, at up to 33 m (110 ft). Vertebrates make up about 5% of all described animal species; the rest are invertebrates which lack backbones. The grouping sometimes includes the hagfish, which have no vertebrae, but are genetically quite closely related to lampreys, which do have vertebrae. For this reason, the sub-phylum is sometimes referred to as "Craniata", as all members do possess a cranium. (click to see all the article on Wikipedia)脊椎動物出現 ~5億3千萬年前

008 SNOWBALL EARTH 雪球地球

SNOWBALL EARTH between ~750 and ~550 million years
Snowball Earth refers to hypotheses regarding paleoclimatic global-scale glaciation, claiming that the Earth's surface was nearly or entirely frozen at some points in its past. The occurrence of Snowball (or Slushball) Earths remains controversial . Proponents claim it best explains sedimentary deposits generally regarded as of glacial origin at tropical latitudes and other enigmatic features of the geological record. Opponents contest the implications of that geological evidence and the geophysical feasibility of an ice- or slush-covered ocean. (click to see all the article on Wikipedia)
