Biology is a subject that fascinates one to no end; mainly because the human body, nay, the living world as a whole, is so captivating. There are so many facets to the living being that a lifetime is not enough to discover everything there is to know about it.

A lot of incredible facts about biology are not covered in school text books, but which exist, just waiting for the curious mind to discover.

Here, we compile a list of incredible biology facts that are sure to freak you out. Here goes-

  1. Did you know, the power generated by our brain is enough to illuminate a bulb? When we are awake, the brain generates enough power to light up a ten watt bulb!

 

  1. While on the subject of the human brain, did you know that a human brain cell has the ability to hold 5 times more information than an encyclopaedia? According to scientific estimates, the storage capacity of our brain is between 3 to 1000 terabytes! Also, the average human being uses not even 6% of the potential of his brain!

 

  1. The human lung is made up of more than 300 million alveoli! And the alveolar surface area is almost 100 times more than the surface of the human body!

 

  1. The hydrochloric acid secreted by the stomach is so potent that the stomach has to manufacture a new lining every three days to avoid digesting itself!

 

  1. The human bone is stronger than granite or concrete! Compared to concrete, the human femur bone is four times greater in support strength!

 

  1. Ever wondered how migratory birds find their way half-way across the globe? Well, they use the Earth’s magnetic field to do so! No kidding! Magnetoreception is a type of magnetic compass present in migratory birds that helps them navigate using the Earth’s magnetic field!

 

  1. The human bone marrow produces 260 billion red blood cells and 135 billion white blood cells each day! Phew! That’s a lot of work!

 

  1. Your body is made up of atoms that are literally billions of years old. Hydrogen is a major component of the human body and the most abundant element in the universe. Did you know that Hydrogen was a by-product of the big bang that took place 13.7 billion years ago? Carbon and Oxygen, the other two major elements of your body, were created between 7bn and 12 billion years ago inside stars. When these stars exploded, they scattered the Carbon and Oxygen atoms across space, some of which found their way towards Earth. Do you know what that really means? It means humans are actually made of stardust- stardust that is billions of years old! Isn’t that startling?

 

  1. Look up into the sky on a clear night. You might catch sight of the Andromeda Galaxy which appears to the human eye as a tiny patch of light. If you can see the Andromeda Galaxy, it’s because the human eye is extremely sensitive to even a few photons of light. Andromeda is the furthest you can see without the use of sophisticated technology, and it is the nearest large galaxy to our Milky Way. But chew this- in space terms, Andromeda is 2.5 million light years away from Earth! That means that the photons of light you’re seeing when you look at Andromeda started out from that galaxy 2.5 million years ago! That is even before human beings evolved! When you catch sight of the light from Andromeda, you’re actually looking back in time through 2.5m years! Goose-bumps inducing fact, isn’t it?

 

  1. The average human body carries ten times more bacterial cells than human cells!
