This is the National Science Museum of Daejeon Metropolitan City Natural History Museum. About 4.5 million years ago, when humans first appeared in Africa, Australopithecus emerged, and from there, Homo habilis, Homo erectus (Peking Man and Java Man), Neanderthals, and modern humans emerged. The most important characteristics that distinguish modern humans from apes, which are ancestors of humans including chimpanzees, are that they walk on two feet and have large brains. Australopithecus, an ancestor of humans that originated from apes that walked on four feet, would have walked on two feet to easily locate predators and escape in the African grasslands, and thus would have used its two arms to use tools. It is estimated that the brain of Australopithecus was about 35 percent of that of modern humans. Migration of Modern Humans Modern humans are believed to have developed diverse racial characteristics as a result of a group that emerged in Africa about 200,000 years ago and spread around the world, adapting to the climate and environment of each region. Although skin and appearance differ depending on race, all humans are ultimately one group. Dokdo Undersea Topography Dokdo, which can be seen above the sea, is a small island, but under the sea, there is a huge seamount that is about 2 km high and about 20-25 cm in diameter at the bottom. In addition, there are Injeongbok Seamount, Simheungtaek Seamount, and Isabu Seamount under the sea around Ulleungdo and Dokdo. The animal kingdom is a multicellular organism with a nuclear membrane and organelles and no cell wall. Since there are no chloroplasts, they do not photosynthesize, but move through locomotion organs and are heterotrophs that obtain nutrients by ingesting food. They are classified according to body symmetry, formation and number of germ layers, relationship between the protostomes and the mouth, type of body cavity, presence or absence of notochord, presence or absence of segments, etc. The plant kingdom is a multicellular organism with a nuclear membrane, organelles, and cell walls made of cellulose. Depending on the presence or absence of vascular bundles, reproduction method, and ovaries, they are classified into bryophytes, ferns, gymnosperms, and angiosperms. Insects consist of a head, chest, and abdomen. They have three pairs of legs and a bilaterally symmetrical structure. Their bodies are made up of many segments and are covered with an outer layer called the cuticle. They live almost everywhere except in the deep sea. Insects are largely divided into wingless scutes and winged scutes. Fish consist of a head, torso, tail, and fins. They reproduce by laying eggs, and most fish are covered with scales. They live in the water by breathing with gills and moving with fins. They are broadly divided into jawless fish, cartilaginous fish with jaws, soft bones, and no swim bladder, and bony fish with jaws, hard bones, and swim bladder. There are about 1,200 species of fish in Korea, of which about 200 species live in freshwater and about 60 species are endemic. Amphibians have four legs and reproduce by laying eggs in water. They live in water when they are young and breathe with their gills, and when they go through metamorphosis and become adults, they come onto land and breathe with their lungs and skin. Since they breathe through their skin, they mainly live in humid environments to prevent their skin from drying out. When they become adults, amphibians are divided into tailless antheridia (frogs, toads) and tailed antheridia (salamanders). There are 20 species of amphibians in Korea, and 6 species are endemic. Pteridophytes reproduce by laying eggs, and most of them are made of a shell that allows oxygen and carbon dioxide to pass through and a membrane that prevents the inside from drying out. The skin is covered with keratinous scales, which prevents moisture from escaping from the body even when living on land. They are classified into crocodiles with their entire body covered with plates, turtles with shells and back plates, lizards without shells and back plates and with legs, and snakes without shells, back plates, or legs. There are 30 species of reptiles in Korea, and there are no endemic species. Birds have beaks without teeth and two modified wings for the front legs. They breathe through lungs and their body surfaces are covered with feathers. Feathers protect the body by insulating, waterproofing, and moisture-proofing, and help maintain balance during flight. They are also used to express courtship during mating. Most birds lay eggs in nests and reproduce. Depending on their ecotype, they are classified into songbirds, harpy harpy, fowl, and raptors. They are also classified by habitat or season. There are about 500 species of birds observed in Korea, and there are no endemic species. Mammals breathe through lungs and their bodies are covered with fur. Most give birth to young and raise them by feeding them milk secreted from their mammary glands. Most live on land and are very diverse in form, habits, and distribution. Mammals are divided into monotremes, marsupials, and placental mammals. #Domestic travel #Travel plan #February travel subsidy event
