Humans have a long period of development after birth. Their life depends less on instinct than other animals, and more on learning. Humans are also born with their brains not so well developed as those of other mammals. This makes for an unusually long childhood, and so makes family life important. If their brains were better developed at birth, th...

Physical appearance
Human body measurements differ. The worldwide average height for an adult human male is about 172 cm (5 ft 7+1⁄2 in), and the worldwide average height for adult human females is about 158 cm (5 ft 2 in).

Life cycle
The human life cycle is similar in some ways to most other mammals. However, there are some differences. The young grow inside the female mother for nine months. After this time the baby is pushed out of the woman's vagina, with its brain only half developed. Unlike most other mammals, human childbirth is somewhat dangerous. Babies' heads are large, and the mothers pelvis bones are not very wide. Since people walk on two legs, their hips are fairly narrow. This means that birth can be difficu...

Music can be made using simple instruments only such as simple drums all the way up to electric guitars, keyboards and violins. Musi...
Race and ethnicity
Humans often categorize themselves by race or ethnicity. Modern biologists know that human gene sequences are very similar compared to many other animals. This is because of the "recent single origin" of modern humans. That is one reason why there is only one human race.: 360 Ethnic groups are often linked by linguistic, cultural, ancestral, and national or regional ties. Race and ethnicity can lead to different social treatment called racism.
