Question

The human species is adapted to quite a range of habitats, from deserts to mountains and from rain forests to tundra. Your job is to determine how humans might be adapted to live in a low gravity environment (half of Earth's gravity).

Write a brief description of the musculoskeletal system of a human that is adapted to a low gravity environment, and why it would look the way it does. Consider the following:

• What would be required to support and move the body, and to support their lifestyle? You are encouraged to look up other (non-human; can be non-mammalian) animals that share these habitats for ideas.
• What if humans had evolved and were adapted to live in very specific habitats? In other words, it would still look *basically* like a human but would have some important differences related to its circulatory and/or breathing systems.
• What would these systems of a human that adapted to a different environment look like, and why would it look like this?
• You should consider the following parts of the musculoskeletal system in your answer: Bone length, Bone diameter, Bone density, Muscle type, location, and size, Anything else you think is important to the musculoskeletal system.

Answer 1

The human species can be adapted to a veritable range of habitats. From the desert to mountains, rain forest to tundra, hot weather to cold weather etc. But the human being cant be adapted into a area of low gravity environment. There will be a lot of musculoskeletal problems , respiratory problems and other associated problems will arise gradually.
     
   The flow of the blood in the area of less gravity will have changes in that of blood flowing in the circulatory system of human in the normal gravity. The red blood cells in the blood will attract towards the gravity and flows the blood to the lower limbs. But as if the person is in the half of gravity of the earths gravity, the circulation of the blood is affected and the person is more prone to having circulatory associated problems such as heart attack . These system will be very difficult for the human beings to adapt to this environment.
  
   The bone density, bone length and the bone diameter is also affected. The bone density will be gradually decreased due to insufficiency in weight bearing and the bone length and diameter is also decreased due to lack of gravitational force which pulls the body into the surface of the ground. Their bones are fragile and there will be no hardness in the bone.
