Why did humans lost their hair or fur on body ???

 Unlike other animals, humans are evolved to have a lot more sweat glands.

Instead of panting and hiding in the shade, our ancestors could cool down by sweating.

But for sweating to work well, body needed less hair to trap the heat and moisture.

This change led to a new way of hunting.  Here humans chase animals over long distances until the prey is collapsed from exhaustion in the heat.

By losing their fur, early humans gained an advantage. With less hair, they could effectively control their body temperature and had greater stamina.

In the hot climates, being less hairy isn't a drawback but it is a survival skill.

Why do owls sleep during the day ??

 Owls are nocturnal creatures.  They are naturally active during night and rest during day.

Owls hunt at night because their eyes are adapted to low light vision.

By hunting at night ,  owls face less competition from other predators.

Daytime sleep helps owls to conserve energy.

During the day, many predators are active.  Owls stay hidden.

Owl's daytime sleep is a part of their survival strategy.

Why doesn't stomach acid burns through our stomach ??

 If we are about to get an acid reflux, we feel a burning sensation when acid from stomach escapes into mouth.

This means stomach acid is harsh enough to irritate the inside of our throat. 

Why doesn't stomach acid burns through stomach ??

Stomach produces gastric juice to aid digestion. The main component of this gastric juice is hydrochloric acid.

It is strong enough to dissolve metal  !!!

Without protection, this strong acid would quickly begin to eat into stomach wall first forming painful ulcers before ultimately burning a hole.

However, cells that line inside of stomach called epithelium produces a very thick, sticky layer of mucus  which is alkaline and buffers the strong acid.

This layer is continuously renewed.

But when this layer is damaged, problems start.  Small breaks can allow acid to penetrate into mucus layer which can lead to inflammation and ulcers.

Avoiding acidic and spicy food and lifestyle changes help to relieve the suffering.
