Bipedalism is the ability to stand or move on two legs.

Unfortunately, humans have not fully adapted to bipedalism, therefore the pelvic region and spine become worn over time in humans. This makes movement much more difficult with age and creates back problems.", "He's very hairy.
The average human has more hair on his body than a chimpanzee. Although the chimp appears to have more hair, most human hair is shorter, finer and less colored than a chimp's, making it difficult to see.

The chimp's hair is designed to protect the animal from the sun, whereas humans have developed other forms of protection.", "Almost human.
About 96% of human DNA is shared with chimps. DNA is information that controls the makeup of an organism, so animals that look alike will have similar DNA. The similarity between chimpanzees and humans (in both DNA and appearance) is considered proof that modern humans and modern apes evolved from a common ancestor. ", "If we were to look at each human body part we might come up with different connections - the DNA of the eye is similar to an octopus, the mouth is like an orangutan, and the heart is like a pig. Scientists are even working on a pig to human heart transplant.", "He's got a big head.
Compared with other animals, human childbirth is difficult, mainly because the child's head is so large. bigger.

Human children are also born rather premature, if they were not the head would grow to large for the mother. At birth, the human child is quite helpless compared with other mammals. ", "Brain power!
The human brain is large in proportion to the body. Brain size compared to body mass gives a rough estimate of the intelligence of an animal.

Scientists often use this equation to estimate the intelligence of a species but will subtract the brain power used to run the body, which in humans is about 25%.", "Do you recognize me?
Humans are one of only six animals to pass the mirror test. The mirror test is a test developed to test the self-awareness of a subject. The subject is placed before a mirror and studied to see if it recognizes itself or not.

The other animals to pass the test are chimps, bonobos, orangutans, dolphins and pigeons. ", "A lot of big talk.
The faculty of speech is a defining characteristic of humans. Exactly when human language developed is not known but it is clear that humans posses an innate and advanced linguistic ability. All present languages today are capable of adapting, translating, and borrowing from other languages.

Children, even if not guided by adults, will often independently develop their own language, sometimes to very advanced degrees, as seen in the Nicaraguan Sign Language incident.", "You've got something in your eye.
Aside from the brain, the eye is the most complex organ in the body, capable of processing about 36,000 bits of information every hour. Only about 1/6 of the eye is exposed and it is an organ constantly at work, but remains the only muscle that needs no rest. ", "Need a shot?

Most diseases can be transferred from humans to gorillas and vice versa, hence the glass cases found in zoos. Baby gorillas are actually given the same inoculations as baby humans.", "That's a toasty fire.
Humans are the only animal to use fire. Fire has provided humans with a sophisticated diet, warmth, and greater control over their environment.

Most other members of the animal kingdom remain frightened of fire, making it an effective tool in scaring off dangerous predators.", "What's all that noise?

There are approximately 6000 human languages spoken in the world today. Some believe that these languages all evolved from a common language - the Proto-World language. It is difficult to prove, but some scientists point to certain common elements in all languages. Regardless of its origin, all known peoples are capable of adapting, translating, and expanding their own language.", "Where's the hammer?

Humans are not the only animals to use tools. Chimps use sticks to dig for ants and extract honey from hives. Some have also been known to use larger branches as poles in escape attempts.

Other animals, like octopuses and even crows, seem to have this ability as well. Scientists use this ability to judge the intelligence of animals.", "Can you do this?

The human child can breathe and drink at the same time, like every other animal. This changes after about three months when the larynx begins moving down to prepare for speech. ", "You're blushing.

Humans are the only animals that blush and cry from emotion. Humans blush fairly regularly, often when embarrassed. It is a rush of blood to the face, along with an increased heart rate. As Mark Twain said, 'Man is the only animal that blushes - or needs to.'", "Got milk?
Like other mammals, the human female produces milk to feed the infant immediately after birth, continuing until the infant is mature enough to eat more solid food.

But humans are one of only mammals to drink the milk of another species and to continue drinking it after infancy.", "It's cold up here.

Humans are the only animals capable of living on the South Pole. The South Pole is the southern most point on the planet and presently part of Antarctica.

At the edges of this continent, seals and penguins exist (although no Polar Bears, they live on the North Pole).", "Did my heart just skip a beat?

The human heart beats about 3 billion times in life time. By repeated contractions the heart pumps blood to the rest of the body. The amount of energy exerted with each pump is similar to that of holding a tennis ball and squeezing it.

It is a remarkable organ, only about the size of a fist and in one day will pump 2,000 gallons of blood. ", "Did you know?

Humans are able to hold their breath longer under water than on land.", "Last Known Survivor

More than 99.9 percent of all the animal species that have ever lived on earth were extinct before Homo sapiens appeared."];
