What Would Happen to Humanoid Bone Structure If the Moon Crashed Into Earth?

In summary, the conversation discusses the potential bone structure of humanoid life if the moon were to crash into Earth and cause a mass extinction event. The conclusion is that there would likely be no significant changes to the bone structure, as evolution is based on adapting to the environment. However, there could be changes to the shape of life forms and changes in tidal activity.

Hi all,

This is a bit of a bizarre question, but:

If some way, some how, the moon crashed into Earth... then (oh so many) years later humanoid life appeared, what might its bone structure be like in contrast to ours?

That is all

There's no reason to think that it would be any different on a very basic level, since we evolved to match our environment and the moon crash thing wouldn't change things as much as living on a different planet would. There would still be vertebrates, invertebrates, plants, fungi, etc. and anyone of them could end up being an intelligent and therefore dominant species.
Lest you think that I wasn't paying attention, the term "humanoid" to me indicates a shape rather than a structure.

The Moon's mass is only 1.2% of the Earth's mass. Why should there be any significant changes to the bone structure?

I think that he's going for the "mass extinction—repopulation" scenario. You have to admit that a lunar impact would to a large extent bugger up our environment.

Thanks Danger for the great response!

So... the change of the shape (sorry, wrong terminology on my part there) of the life forms would be pretty much the same, that's super good to know.

There would be much less tidal activity also... What possible things might happen to undersea life?

again thank you so very much

Maybe our ancestors would have never made it out of the water, if they had not stranded during a low tide one day. Thanks Mr. Moon!

Well, tides wouldn't completely disappear. Solar gravity and Earth's axial tilt also contribute.

What is bone structure?

Bone structure refers to the arrangement and composition of bones in the human body. Bones are made up of a combination of collagen fibers, calcium, and other minerals, and their structure is designed to provide strength, support, and protection for the body.

How do bones grow and develop?

Bones grow and develop through a process called ossification, where new bone tissue is formed and replaces old or damaged bone tissue. This process is primarily controlled by hormones and is influenced by factors such as diet, exercise, and genetics.

What are the different types of bones in the body?

There are five main types of bones in the body: long bones, short bones, flat bones, irregular bones, and sesamoid bones. Long bones, such as the femur and humerus, are responsible for movement and support, while flat bones, such as the skull and ribs, protect vital organs. Short bones, like those found in the wrist and ankle, provide stability and flexibility, and irregular bones, such as the vertebrae, have unique shapes to fulfill specific functions. Sesamoid bones are small, round bones found near joints and help to reduce friction and provide leverage for muscles.

What is the purpose of bone structure?

The purpose of bone structure is to provide strength and support for the body, protect vital organs, and enable movement and flexibility. Bones also play a crucial role in the production of blood cells and the storage of minerals, such as calcium and phosphorus, which are essential for maintaining healthy body functions.

Can bone structure change over time?

Yes, bone structure can change over time due to factors such as aging, injury, and lifestyle choices. As we age, bones can become weaker and more brittle, leading to conditions like osteoporosis. Injuries can also affect bone structure, causing fractures or deformities. Additionally, diet and exercise can impact bone structure, as a lack of proper nutrition and physical activity can result in weaker bones.
