The evolution of the brain refers to the progressive development and complexity of neural structures over millions of years, resulting in the diverse range of brain sizes and functions observed across different species today, particularly in vertebrates. The evolution of the brain has exhibited diverging adaptations within taxonomic classes ...
The brain controls most of the activities of the body, processing, integrating, and coordinating the information it receives from the sensory nervous system. The brain integrates the instructions sent to the rest of the body. The brain is contained in, and protected by, the skullof the head. The cerebrum, the largest part of the human brain ...
History of neuroscience. From the ancient Egyptian mummifications to 18th-century scientific research on "globules" and neurons, there is evidence of neuroscience practice throughout the early periods of history. The early civilizations lacked adequate means to obtain knowledge about the human brain. Their assumptions about the inner workings ...
Bone fragments unearthed in a cave in central Germany show that our species ventured into Europe's cold higher latitudes more than 45,000 years ago - much earlier than previously known - in a ...
Ancient DNA. Cross-linked DNA extracted from the 4,000-year-old liver of the ancient Egyptian priest Nekht-Ankh. Ancient DNA (aDNA) is DNA isolated from ancient sources (typically specimens, but also environmental DNA). [1][2] Due to degradation processes (including cross-linking, deamination and fragmentation) [3] ancient DNA is more degraded ...
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 ...
Homo habilis (lit. 'handy man') is an extinct species of archaic human from the Early Pleistocene of East and South Africa about 2.3 million years ago to 1.65 million years ago (mya). Upon species description in 1964, H. habilis was highly contested, with many researchers recommending it be synonymised with Australopithecus africanus, the only ...
Paleontology (/ ˌpeɪliɒnˈtɒlədʒi, ˌpæli -, - ən -/ PAY-lee-on-TOL-ə-jee, PAL-ee-, -ən-), also spelled palaeontology[a] or palæontology, is the scientific study of life that existed prior to the start of the Holocene epoch (roughly 11,700 years before present). [citation needed] It includes the study of fossils to classify ...
