a primate of a taxonomic tribe ( Hominini ), which comprises those species regarded as human, directly ancestral to humans, or very closely related to humans.
✭The Hominini, or hominins, form a taxonomic tribe of the subfamily Homininae ("hominines"). Hominini includes the extant genera Homo (humans) and Pan (Chimpanzees and Bonobos), but excludes the genus Gorilla (gorillas).
✭The term was originally introduced by John Edward Gray (1824), long before any details on the speciation of Pan and Homo were known. Gray's tribe Hominini by definition includes both Pan and Homo. This definition is still adhered to in the proposal by Mann and Weiss (1996), which divides Hominini into three subtribes, Panina (containing Pan), Hominina ("homininans", containing Homo "humans"), and Australopithecina (containing several extinct "australopithecine" genera).
Photosynthesis requires sunlight, carbon dioxide and water to produce glucose. This simple sugar is a carbohydrate that combines with other sugars to form the plant's structure and stores energy for future use. Hope it's useful!
Medulla oblongata is found at the lower half of the brainstem continuous with the spinal cord. The medulla oblongata controls the center of vomiting, vasomotor centers for regulating heart rate, cardiac, respiratory and blood pressure. Furthermore, Medulla oblongata connects the higher levels of the brain to the spinal cord and also controls autonomic functions.
