human-homosapien
Humans (Homo sapiens) are the only extant members of the subtribe Hominina. Together with chimpanzees, gorillas, and orangutans, they are part of the family Hominidae (the great apes, or hominids). A terrestrial animal, humans are characterized by their erect posture and bipedal locomotion; high manual dexterity and heavy tool use compared to other animals; open-ended and complex language use compared to other animal communications; larger, more complex brains than other animals; and highly advanced and organized societies.[3][4]
Early hominins—particularly the australopithecines, whose brains and anatomy are in many ways more similar to ancestral non-human apes—are less often referred to as "human" than hominins of the genus Homo.[5] Several of these hominins used fire, occupied much of Eurasia, and gave rise to anatomically modern Homo sapiens in Africa about 315,000[6] years ago.[7][8] Humans began to exhibit evidence of behavioral modernity around 50,000 years ago, and in several waves of migration, they ventured out of Africa and populated most of the world.[9]
The spread of the large and increasing population of humans has profoundly affected much of the biosphere and millions of species worldwide. Advantages that explain this evolutionary success include a larger brain with a well-developed neocortex, prefrontal cortex and temporal lobes, which enable advanced abstract reasoning, language, problem solving, sociality, and culture through social learning. Humans use tools more and better than any other animal; and are the only extant species to build fires, cook food, clothe themselves, and create and use numerous other technologies and arts.
Humans uniquely use such systems of symbolic communication as language and art to express themselves and exchange ideas, and also organize themselves into purposeful groups. Humans create complex social structures composed of many cooperating and competing groups, from families and kinship networks to political states. Social interactions between humans have established an extremely wide variety of values,[10] social norms, and rituals, which together undergird human society. Curiosity and the human desire to understand and influence the environment and to explain and manipulate phenomena (or events) have motivated humanity's development of science, philosophy, mythology, religion, anthropology, and numerous other fields of knowledge.
Though most of human existence has been sustained by hunting and gathering in band societies,[11] increasingly many human societies transitioned to sedentary agriculture approximately some 10,000 years ago,[12] domesticating plants and animals, thus enabling the growth of civilization. These human societies subsequently expanded, establishing various forms of government, religion, and culture around the world, and unifying people within regions to form states and empires. The rapid advancement of scientific and medical understanding in the 19th and 20th centuries permitted the development of fuel-driven technologies and increased lifespans, causing the human population to rise exponentially. The global human population was estimated to be near 7.7 billion in 2015.
Velociraptor
Velociraptor was a type of dromaeosaurid dinosaur (bird-like dinosaur). There were two species of Velociraptor that lived in Central Asia 75 to 71 million years ago (end of Cretaceous period). First fossil of Velociraptor was discovered in 1923 in a Gobi Desert in Mongolia. Second species has been discovered in 2008 in China. Velociraptor lived in arid, sandy areas. It became very popular and widely recognized after the movie "Jurassic Park", even though it wasn't portrayed correctly (Velociraptor wasn't extremely intelligent, large and covered with scaly skin).
Interesting Velociraptor Facts:
Velociraptor was able to reach length of 6.6 feet and weight of 33 pounds.
Velociraptor had large, up-curved skull that was concave on the upper surface and convex on the bottom side. It had long, narrow snout and two large hand-shaped appendages with three curved claws. These appendages were anatomically very similar to the wing bones of modern birds. Velociraptor had long, inflexible tail whose main purpose was to provide balance.
Name "Velociraptor" means "swift thief". Name refers to the ability of this dinosaur to quickly grab its prey.
Hind feet of Velociraptor were equipped with sharp claws. 3-inches-long, sickle-shaped claw on the second toe was used for killing and to prevent escape of the prey.
