Stroke: Causes, Symptoms, Diagnosis and Treatment. Stroke is the 5th leading cause of death in the US, with one person dying every 4 minutes as a result. For black people, stroke is the 3rd leading cause of death. Approximately 800,000 people have a stroke each year; about one every 40 seconds. Strokes occur due to problems with the blood supply to the brain: either the blood supply is blocked or a blood vessel within the brain ruptures, causing brain tissue to die. A stroke is a medical emergency, and treatment must be sought as quickly as possible.
1 A hominid is a member of the family Hominidae: all of the great apes. 2  A hominine is a member of the subfamily Homininae: gorillas, chimpanzees, humans (excludes orangutans).  A hominin is a member of the tribe Hominini: including humans.
Hominids are included in the superfamily of all apes, the Hominoidea, the members of which are called hominoids. Although the hominid fossil record is far from complete, and the evidence is often fragmentary, there is enough to give a good outline of the evolutionary history of humans.
