The useless ideas are the preeminent weapons of animals!

It is hard to suspect that the features that seem to be 'leftovers' of animals such as the chicken crest, the tiger's fur color or the platypus's nose are the evolutionary achievements, helping them Become superior to your opponent!

Have you ever wondered, why tigers have yellow-striped fur, while this color makes them quite stand out between the jungle environment and their prey will be easy to spot? In fact, the tiger's prey is mostly deer, deer and other herbivores, not humans, and these animals suffer from color blindness , leading to them only seeing the world through green colors. - lam, this has turned the 'costume' of the lord of the lord into a perfect camouflage.

In a strange and somewhat adorable form, few people expect platypus to be a formidable predator in nature.The secret weapon of the animal half this half-duck animal is the two nostrils located in an extreme position, very sensitive to movement and electric current.Thanks to this biological radar, it can detect weak electric fields or any prey in the water environment, especially crayfish lobsters.

This human-like appearance of anteater only appears when they are in danger.Because there are no teeth but possess very strong and sharp claws, this posture helps them to use this weapon in the most effective way, which makes large carnivores also shy when face anteater.

The chicken crest is not as useless as we think it is, but in fact this is a huge evolution of the chicken compared to many other birds.According to biologists, because birds do not have sweat glands, they cannot cool their bodies the way humans and many animals still apply.So, during evolution, in chickens that have gradually formed a crest, an organ that replaces sweat glands.Specifically, when the temperature is high, the blood of the chicken will be transmitted through the crest and cooled here, thereby helping to regulate body temperature.

Few people know that the big, bizarre nose of the saiga antelope is one of the main reasons that this animal still exists and grows up to the present time.Specifically, the special nose has helped them effectively filter the air.Along with it is the ability to regulate body temperature (warming the inhaled air during cold weather, cooling in hot weather), thereby providing a rapid adaptation to climate change for saiga antelopes.

The long, spiky mouth of the swordfish acts as a biological radar, similar to the nose of the aforementioned platypus.Specifically, with the sensation of the electric current in the water, the swordfish easily understands what is hidden in the surrounding environment.In addition to the sensing function, this 'saw blade' also helps the blades to attack and stun the prey.
