Exchange rate history of the Indian rupee. This is a list of tables showing the historical timeline of the exchange rate for the Indian rupee (INR) against the special drawing rights unit (SDR), United States dollar (USD), pound sterling (GBP), Deutsche mark (DM), euro (EUR) and Japanese yen (JPY). The rupee was worth one shilling and sixpence ...
The evolution of human intelligence is closely tied to the evolution of the human brain and to the origin of language. The timeline of human evolution spans approximately seven million years, [1] from the separation of the genus Pan until the emergence of behavioral modernity by 50,000 years ago. The first three million years of this timeline ...
Australopiths lived from 3.85 to 2.95 million years ago with the general cranial capacity somewhere near that of the extant chimpanzee—around 300–500 cm 3. [54] [55] Considering that the volume of the modern human brain is around 1,352 cm 3 on average this represents a substantial amount of brain mass evolved. [56]
The sequence of human evolution from Australopithecus (four million years ago) to Homo sapiens (modern humans) was marked by a steady increase in brain size. [ 264 ] [ 265 ] As brain size increased, this altered the size and shape of the skull, [ 266 ] from about 600 cm 3 in Homo habilis to an average of about 1520 cm 3 in Homo neanderthalensis ...
The timeline of human evolution outlines the major events in the evolutionary lineage of the modern human species, Homo sapiens, throughout the history of life, beginning some 4 billion years ago down to recent evolution within H. sapiens during and since the Last Glacial Period. It includes brief explanations of the various taxonomic ranks in ...
The brain is an organ that serves as the center of the nervous system in all vertebrate and most invertebrate animals. It consists of nervous tissue and is typically located in the head (cephalization), usually near organs for special senses such as vision, hearing and olfaction. Being the most specialized organ, it is responsible for receiving ...
The hominoids are descendants of a common ancestor. Human evolution is the evolutionary process within the history of primates that led to the emergence of Homo sapiens as a distinct species of the hominid family that includes all the great apes. [1] This process involved the gradual development of traits such as human bipedalism, dexterity ...
Sagittal view of cingulate region of human brain with a Talairach grid superimposed in accordance with standard locators. Talairach coordinates, also known as Talairach space, is a 3-dimensional coordinate system (known as an 'atlas') of the human brain, which is used to map the location of brain structures independent from individual differences in the size and overall shape of the brain.
