Human

Humans are a race of sentient, and very prominent species residing on a large terrestrial planet called Earth in the Sol System.

Biology
Humans closely reasemble the Qlaxika. Like most species, they have a torso, four limbs and a head. Humans have two eyes on their heads, a strong nose used for both breathing and smelling and a mouth used to eat. Humans also have two hands with five fingers on both, mirrored by their feet, which also have five fingers on both sides. Like most species, they are born in either male or female genders.

Anatomy
Human height averages from 1.7 meters as an adult and much lower as a child. Their internal structure, along with the Qlaxika is different than other species.

Humans have highly developed brains; they can think before they act and think reasonably. Their organs are connected to their brains by nerves, long wires which send information to the human brain for processing at over 270 miles per hour (435 km/h) Only Humans and Qlaxika have nerves. To digest, they use a long esophagus, at over 1 meter (3.2 feet) in length. The food is later neutralized inside their stomachs, huge pouches containing gastric acids and later send down their intestines and their nutrients are absorbed by villi.

Their respiratory system starts with their nose. This absorbs Earth air (oxygen) and sends it down a tube known as a windpipe and into their lungs. The lungs later absorb the air and release carbon dioxide which travels up the windpipe and through the mouth, where it enters the air.

Origin
Humans first appeared over 250 thousand years ago, making them relatively young compared to the Megalons, which at 2.7 billion years old, stand as the oldest living species in the Milky Way. Humans originated from apes, close relatives which come from the same planet, Earth. The process of evolution evolved the apes into the humans.
