Science Presentation About ‘Why humans are considered as complex organisms’

Before I start, I would like to thank Teacher Asliza for giving me an opportunity to present my PBS Band 6D2E1…

Humans (variously Homo sapiens and Homo sapiens sapiens) are primates of the family Hominidae, and the only extant species of the genus Homo.Humans are distinguished from other primates by their bipedal locomotion, and especially by their relatively larger brainwith its particularly well developed neocortex, prefrontal cortex and temporal lobes, which enable high levels of abstract reason Humans (variously Homo sapiens and Homo sapiens sapiensing,language, problem solving, and culture through social learning. Humans use tools to a much higher degree than any other animal, and are the only extant species known to build fires and cook their food, as well as the only known species to clothe themselves and create and use numerous other technologies and arts. The scientific study of humans is the discipline of anthropology.

Humans are uniquely adept at utilizing systems of symbolic communication such as language and art for self-expression, the exchange of ideas, and organization. Humans create complex social structures composed of many cooperating and competing groups, fromfamilies and kinship networks to states. Social interactions between humans have established an extremely wide variety of values, social norms, and rituals, which together form the basis of human society. The human desire to understand and influence their environment, and explain and manipulate phenomena, has been the foundation for the development of science, philosophy, mythology, and religion.

The human lineage diverged from the last common ancestor with its closest living relative, the chimpanzee, some five million years ago, evolving into the australopithecines and eventually the genus Homo. The first Homo species to move out of Africa was Homo erectus, the African variety of which, together with Homo...
