Humans, known as Homo sapiens by taxonomically (Latin for "wise man"). Humans are the only living species in the Homo genus of bipedal primates in Homicidal, the great ape family. The earth is about 4.5 billion years old. Humans have been on earth for a miniscule percentage of that interval. Anatomically modern-appearing humans originated in Africa about 195,000 or 200,000 years ago, reaching full behavioral modernity around 50,000 years ago.Human has two sets of 23 chromosomes, each set received from one parent.( 22 pairs of autosomes and one pair of sex chromosomes ) If any pair fails to work Human will born in… The pattern of human postnatal brain growth differs from that of other apes. Human body types vary substantially. Although human body size is largely determined by genes. The average height of an adult human is about 1.5 to 1.8 m (5/6 feet) tall, although this varies significantly from place to place and depending on ethnic origin. The average mass of an adult human is 54–64 kg (120–140 lbs) for females and 76–83 kg (168–183 lbs) for males. Weight can also vary greatly. But if scientists found any bones of Human Being that is 7-8 feet tall they can not assure us that the owner of the bones was evolved. Because it is not evolution; it is a abnormal species. Or it will be that version of Human Being who was too long/tall –as described in Quran. Once Allah created a group of Humans.
