As you age your bone density decreases, thus resulting in you becoming shorter. Your limbs in turn are shorter as well.
weathering, and erosion
In simple terms - evolution ! Snakes & lizards share a common ancestry. While lizards chose to keep using their limbs, snakes evolved to depend on their external limbs less over time. Eventually, over many thousands of years, their limbs grew shorter until they disappeared completely. The only evidence their limbs existed - is remnants of bone in their skeletons.

To answer this question, let's look at the Peruvians in the Andes. Due to the high altitude, they have developed bigger lungs due to thinner air and shorter limbs for blood flow. This is a perfect example of how animals, especially humans, can adapt to changing climates over a large period of time.

It theory, it is possible. But would you want to? Most people can survive a long time without food, but a much shorter time without water.
Telomerase ends become shorter as humans age. This happens in part because of the process known as the end replication problem, whereby strands of DNA become uneven over time.
A starfish has five limbs and if one of those limbs (which can also called arms or legs) is lost it can regrow over time. A starfish that is halved can grow into two starfish.
The difference is that growing happens slowly over time, while sprouting can go over a shorter period of time.
Shadows become shorter only during the morning (before noon). Shadows are longest at sunrise and sunset, when the angle with the surface is greatest.
