The Human Race is considered the most intelligent species on Earth. If the colonization of Mars is successful, the human race will be the only known species living on more than one planet.
Contents
What makes humans different from other species?
Unlike other known species, the human race has created artificial means for a great variety of activities. The accumulation and distribution of knowledge in written form and the global communication with nearly the speed of light is a special ability. The human race is also the only known species capable of space travel.
Biological
Adult human individuals on Earth have the following properties:
- Height: about 155..190 cm
- Weight: about 50..80 kg
- Maximum age: about 80 years
- Energy consumption by food: 6000 to 16000 kJ (1,66 to 4,44 kWh) (depends on size and activity)
- Air consumption: (to be completed)
- Water consumption: 2 to 4 liters per day
- Blood heat: 37°C
- Preferred environmental temperature: 20°C
- Symbiotic relationship with a number of microorganisms (especially in the gut.)
The metabolism of human beings depends, just like animals and various microbes, on water. The human body contains about 70% water.
Ah that's great I would love to visit a place like that!All the outfits from the games were cool and the D'Ni eltevaor was awesome Also, I realized I've only seen Rand Miller in pictures before, so it was cool to see him in the video. I might have to take a second look because I was pretty overwhelmed by all the things to look at in the video, and my eyes momentarily paid much more attention than my ears. So a second listen could give me a clue to what they're talking about!

Open issues
- What is the optimum temperature in the artificial habitat to minimize the energy consumption by food (may be different at day and night, during work and leisure)?
